Propylene Glycol — Dog Food Aid or Automotive Antifreeze?

Share

Propylene glycol is a controversial additive used to help preserve the moisture content in some commercial dog foods.

AntifreezeYou may already recognize this chemical by its more “infamous” use: as the key component in newer automotive antifreeze.

However, propylene glycol is considerably safer (less toxic) than its far more dangerous cousin — ethylene glycol.

Yet because of its proven ability to cause a serious type of blood disease — Heinz body anemia — propylene glycol has been banned by the FDA for use in cat food.

However, it can still be used to make dog food.

Propylene Glycol in Dog Food
The Bottom Line

No matter how safe propylene glycol may seem, it’s the continuous feeding of this controversial chemical additive to the daily diet of any animal that concerns me.

And if you love your dog as much as I love Bailey and Molly, long term use of any non-nutritive additive should concern you, too.

  • ThedRat

    You are incorrect, Dr, It is a used widely in food and industrial processing as an antifreeze and food additive.

  • Melissaandcrew

    Wow its obvious that you have not done research. The newer antifreezes are propylene glycol based instead of Ethylene glycol, commonly touted as being “less toxic” to animals. This is not “new” but rather have been on the market for a number of years. I agree-idiots will believe anything-they also will post inaccurate comments..course, they usually do not have a “DR” before their name : )

  • Dr. Whaley

    As soon as they said propylene glycol is in antifreeze I knew this
    article wasn’t researched at all. It’s Ethylene glycol that’s in
    antifreeze. Idiots will believe anything.

  • tjcole

    It’s killing dogs, the new Milk Bone Brushing Chews contain it do Not Feed These To Your Dog..!

  • Dori

    Stop feeding your dog Beneful. Transition him to a better food. Check out the 3 & 4 star reviewed food. Beneful is really one of the worst foods out on the market. Also please throw away the Pupperoni’s and don’t feed your dogs things like that. Another awful product on the market. Just because he’s 14 1/2 now doesn’t mean that he might not have a better chance with a better Grain Free food. Also no soy in the ingredients.

  • Cyndi

    Beneful is one of the worst foods you can feed. You should try getting your poor pup on a better food right away. NutriSource I’ve heard is pretty easy to transition to and a much better food. You can try giving probiotics and digestive enzymes to make the switch easier. You could also buy some good canned food and use as a topper, it’s much better for dogs than dry. Good luck to you and your boy.

  • Sandra Devine

    I’ve been feeding my golden retriever Beneful Health Weight for years and he has neurogical problems which affected his hind legs, don’t know if this is the cause or not and he has also had Pupperoni once a day as a treat. He is 14 1/2 now so now I worry that may be what caused his hind legs not to work. (like dishrags).

  • Misty Hall

    More testimonies about PG. We need to know and pay attention that this is not in our food, toiletries or household products. Throw them out.

    Notification to Industry: Products using oils, glycerin, or protein derived from the Jatropha plant may have toxic effects
    This includes Propylene Glycol. Sorbitol and Glycerin http://www.fda.gov/ForIndustry/IndustryNoticesandGuidanceDocuments/ucm391133.htm

  • Shropshire Lass

    Thanks for that clarification.. I see now that Food grade IS Pharmaceutical grade. However, the issue as far as the FDA is concerned is that there is no test available for the toxins in Jatropha-derived PG, Glycerin and Sorbitol (products used in BENEFUL and Jerky Treats for example). A few milligrams of undetectable Curcin or Ricin can kill a dog. Can you imagine the impact of contaminated PG ending up in a few million flu vaccinations? Think Russian spy assassination! Think Chinese bioterrorist attack..

  • Shropshire Lass

    Bob, NO high end dog foods add Propylene Glycol as far as I am aware .. please name me one if you can.

  • Shropshire Lass

    I DID my research.. and poisoning still can occur. 1. Kulkarni ML, Sreekar H, Keshavamurthy KS, Shenoy N. – Jatropha curcas – poisoning. The Indian J Pediatr 2005; 72 : 75-76. “though it is commonly believed that roasting detoxifies the seeds, catastrophes have been reported after eating roasted seeds..”

  • Shropshire Lass

    No, Purina’s source of Propylene Glycol has NOT been revealed. They said that this was “proprietary” information when I approached them!

  • Jonathon Brownback

    It’s the raw, untreated seeds that are toxic…. They’re actually commonly eaten as a snack after roasting. -_- do your research…

  • Think about it

    Since Benefu by Purina has been sold since 2001…with feeding trials pre-approval, plus ongoing feeding at the facilities…I would say those “trials” have been ongoing for over 14 years.

  • Think about it

    It IS on the label, so you can choose to not buy it. Let others do as they please, also.

  • Think about it

    It keeps the food from going rancid for one thing.

    Tufts Veterinary Newsletter reported that a medium-sized dog would have to ingest about 20 ounces of propylene glycol before getting seriously ill. That is over 2 cups!

  • Think about it

    It has NOT been proven to be any of that, except if a person is sensitive to it. It does NOT “provoke skin irritation” unless you are sensitive. It is also in intravenous medicines!
    Cats are not dogs, and react differently.
    “Any substance that is created in a lab doesn’t belong in food.”???
    “If the definition of natural is something that exists in nature, and has not been subjected to ANY chemical change, this would suggest that (assuming that you eat cooked food) a large proportion of the food you eat is not natural…as the process of cooking initiates chemical change…so, in effect, much of our diet is comprised of synthetic chemicals.”
    There is no body mechanism that can distinguish between synthetic and natural.
    Also…”Many of the ingredients used in natural health products like all the B vitamins (B1, B2, B3, B5, B6, etc), minerals like selenium, zinc, boron etc., and virtually all the amino acids are synthesized in laboratories because they are much more commercially viable. Trying to extract a molecule from nature and then concentrate it in a high enough potency is often just too costly.”

  • Think about it

    It was patented in 1931 for heaven sake. It is in over a thousand products.

  • Think about it

    Critical information left out…the grade of PG used in pet food is the pharmaceutical grade, NOT the industrial grade used in auto antifreeze. Also…auto anti-freeze contains other additives like rust inhibitors, etc. There is no evidence it is the culprit in any illness or death. Purina has stated its PG is sourced in the U.S.

  • Diana Dellana

    if you bake i found Pg in most natural flavorings

  • theBCnut

    Well, there you go. I wouldn’t feed a pig those soft foods and I certainly wouldn’t feed them to my dog. They are nothing but junk food. OK for an occasional treat, but definitely not ok to eat day in and day out as the only source of nutrition.

  • theBCnut

    Um, that’s what the post I was replying to said. That’s what I was saying I missed. We’ve recently found that essential oils work better than our emergency inhalers. We have made our own inhalers with peppermint arvensis, eucalyptus radiata, fir balsam, thyme, and birch.

  • Mike

    The absence of mold.
    PG has anti-fungal and anti-microbial properties, that prevents the growth of molds. That’s why its in “soft” dog foods, and also used in hospital air purifiers (which doctors and nurses inhale from constantly while at work).

  • Mike

    Check the ingredients on her inhaler. PG’s there too.

  • Mike

    Because the WHOLE POINT of this discussion is to NOT ingest the other 3000 known chemicals and poisons in cigarettes.

  • Mike

    Then I wonder why it’s also used in most vaccinations? If it’s considered safe to inject directly into the blood stream, how is inhaling it (which by the way is done 24/7 in hospitals) going to be so bad? Yes, Doctors and Nurses have been inhaling the stuff on a daily basis for 60+ years !

  • Mike

    Hope you don’t take medicines. NyQuil uses it, almost ALL asthma inhalers use it. I’ll bet YOU use it daily and just don’t realize it. Start looking at the ingredients of things you use, and you’ll find it in more places than you think.

  • Patti BluCowgirl Holly

    I am a customer assistance team member at Virgin Vapor http://www.virginvapor.com and we offer ZERO nic and /or ZERO PG Organic E-Liquids, we do let our family of ccustomers order 50VG/50PG E-Liquids, but we keep our PG nowhere in the vicinity of our VERY CAREFULLY SOURCED Palm Vegetable Glycerin and I ca not imaging wanting our Organic product with PG added to it. It reminds me of people that want a salad with a tanker of Cola with corn syrup and sugar… OY! I do furbaby rescue, transport & foster along with many furbabies that own me and I can’t magine EVER having my furbabies breathe or ingest PG, why the heck would I. Especially after I took the time to quit using analogs. JMHO here, sorry to go on so long ;)

  • Deirdre Doyle

    There are some dubious sources there – Dow Chemical funded studies, for example. Further, although I might be willing to concede that PG has low toxicity, I prefer not to expose my animals to any toxicity that may be avoided, especially day after day after day. It is one thing to be exposed to something occasionally, but relentless exposure for years has not been studied, I see. Also PG appears in dog food that is characterized by many low-quality ingredients and so is a good indicator of a low-quality food as a rule of thumb.

  • Shropshire Lass

    BENEFUL and JERKY TREAT still KILLING and SICKENING DOGS.. update: Jatropha contains RICIN and not just lethal Curcin .. well, that explains a lot about its killer potential! It shares a very similar toxicity profile to the Castor Oil plant because both Jatropha and Castor oil plant are members of the SAME FAMILY.. Euphorbia. Even more worrying, Castor Oil plant is ALSO being used as a biofuel feedstock in China, India, Brazil and other countries.. remember that most PROPYLENE GLYCOL, GLYCERIN and SORBITOL, all used by Putrina and by most jerky treat manufacturers, can come from BIOFUEL, produced very cheaply in mainly third world countries such as India, China and Brazil! I believe that ONLY when contaminated Propylene Glycol ends up in vaccinations where it can make up 40% of the ingredients, will serious attempts be made to find tests for these toxins. http://earthgenbiofuel.com/wp-content/uploads/2013/05/EarthGen-Biofuel-Castor-Bean-Production.jpg

  • Shawna

    Like Patty, I don’t think that ends the discussion.. If you vape you are likely familiar with the phrase “throat hit”. There are several factors that create a more intense throat hit but the amount of PG in the product is a major factor. If one is getting too much of a throat hit they can reduce it by replacing some or all of the PG with vegetable glycerin.

    My co-worker and I have both had some painful throat hits from juices high in PG (with varying nicotine levels (including zero nic)). I have a Halo unit and prefer juices with no PG.

    According to this website a throat hit that is too strong can be damaging to your throat. http://www.learn.eversmoke.com/throat-hit-and-electronic-cigarettes.html

    …if I switch to anything, maybe I’ll give those Blu ecigs a shot. No antifreeze there.

    Woooah there, not so fast… before you invest in one, check the content ingredients and the forums for how to make your own. I think you will find that many if not most of the flavoring ingredients have PG in them. :( dang!

  • Moneyispower

    “The Department of Health and Human Services (DHHS), the International Agency for Research on Cancer (IARC), and the EPA have not classified propylene glycol for carcinogenicity. Animal studies have not shown this chemical to be carcinogen.”

    Sorry Rover, we listened to Mike.

  • Shropshire Lass

    PROPYLENE GLYCOL, adds sweetness to food and is a humectant (allows more water to be added to the food to make it look “meatier”) Propylene Glycol is also an antifreeze that has one third of the toxicity of the more commonly known antifreeze Ethylene Glycol. It is also a possible carcinogen. Now THESE are the kickers..

    1. The Chinese manufactured product can be contaminated with Diethylene Glycol (DEG). This is not the case with the way more pure, much more expensive, food grade product. DEG has caused organ failure and death in humans and animals.

    http://www.accessdata.fda.gov/cms_ia/importalert_145.html

    2. Propylene Glycol along with Glycerin and Sorbitol can also be manufactured in China from Jatropha, a highly toxic plant, used to make biodiesel, from which these substances can be derived. There is NO test for Jatropha toxins and the FDA is desperately looking for one right now. Three Jatropha seed are enough to kill a human!

    FDA wants industry to watch for glycerin from Jatropha – http://www.fiercepharmamanufacturing.com/story/fda-wants-industry-watch-glycerin-jatropha/2012-07-10#ixzz2iYgZocBN

    FDA Notification to Industry: Products using oils, glycerin, or protein that were derived from the Jatropha plant may have toxic effects
    http://www.fda.gov/downloads/ForIndustry/IndustryNoticesandGuidanceDocuments/UCM310867.pdf

    The most prominent symptoms of jatropha intoxication are nausea and vomiting followed by watery diarrhea after a delay of 30 minutes to 2 hours from the time of ingestion. There is also acute abdominal pain and burning feeling in the throat. In severe poisoning these symptoms progress to hemorrhagic gastroenteritis and marked dehydration.

    Hind limb weakness has been reported in several species.

    In serious cases of poisoning, liver damage may occur.

    The bottom line?

    Do NOT give your pets ANY product containing Propylene Glycol, Glycerin or Sorbitol!

  • Hound Dog Mom

    If you read the above post you’ll see that propylene glycol can cause issues in very low concentrations. Water can be toxic but it would sure take a lot of it. Water is also essential, propylene glycol is not. Why run the risk for an item is not essential and offers no potential benefit?

  • Troy Foster

    Dihydrogen monoxide (water) is also a chemical….let’s ban that!

  • Texas Mom

    My experience is– Propylene Glycol is harmful. Noticed son had developed grooves on the top of his head. These grooves were PG deposits, since he had gotten too much of it. Searched our foods and toiletries. Had to throw away many foods, sports drinks, energy drinks, deoderant, toothpaste, shampoos, cream rinse, mouthwash, shaving cream, etc. We found PG in about 25 products in kitchen pantry and bath cab.

    Yikes!!!! At first, the grooves on head from the PG, were hills and valleys in head. It was so strange. Did he eat or wear products with PG???? Yep, we found them, tossed them.

    The worst culprits were DEODERANT, Sports drinks, and some candies!!! Son was using too much deoderant, TOO OFTEN, in order to smell nice!!!! Vanity! Or, maybe just a young person, tricked by the mfg, thinking it was SAFE. And, he liked his sports drinks and certain candy.

    PG, in large quantities, was UNSAFE for him. Body did not digest it, just eliminated some, as much as body can, and stored the rest. So, my son quit eating PG, and quit using it on skin. His ridges are going away gradually. It has been about a year without PG products, and the condition is mostly gone!!!! Hurray! We found the cure!!!!!!!!!! DO NOT INGEST Propylene GYLCOL !!! Do not eat it, or put it on your skin. Avoid these products, and drink more WATER, to gradually flush this stuff out of your system!!!!!!

    One final note. In case someone does not understand, the things you put ONTO your skin, will soak INTO your skin and go into your body. If your kidneys and liver cannot eliminate ALL of the PG you take in, your body will store it. Thanks!! [email protected]

  • Hound Dog Mom

    Good thing I don’t eat store bought cake very often – sure tasted good though. I totally get why dogs love their Beneful and ‘Ol Roy. lol.

  • Pattyvaughn

    I think it is used in the cake mix to keep it moist while it’s sitting around. I wouldn’t be surprised if they put it in frosting for the same reason.

  • Hound Dog Mom

    I think it’s used in frostings too for commercially made baked goods, I got some cupcakes once that had propylene glycol.

  • Jen

    It’s not just in DOG food…. they’re using it instead of Aspartame (Nutrasweet) in many sugar-free foods for humans too!! I’ve recently noticed it in the water-flavorings like Mio and Crystal Light!!

  • making mischief55

    I don’t know about anybody else, but I am extremely sensitive to this additive. I am trying to find out when this first started being added to our products and what the first product was. As I recall my first experience with a bad reaction was with my sister’s noxzema in 1968. It scaled my face; made it look like the side of the trout that my dad had caught the week before. I would like more information if anyone has it. thanks

  • Amanda

    Ok, so they banned it from cat food and it’s not really safe to feed to fido, but we’re supposed to believe it’s safer than regular cigarettes? When comparing antifreeze to my Marlboros, I think I’ll just stick with what I already know. Or if I switch to anything, maybe I’ll give those Blu ecigs a shot. No antifreeze there.

  • Mike

    The FDA has categorized propylene glycol as “Generally Recognized as Safe.”
    An interesting fact about propylene glycol is that it is non-toxic when
    ingested even in reasonably large amounts. Unlike its dangerous and
    frequently lethal cousin, ethylene glycol, PG is easily metabolized by
    the liver into normal products of the citric acid metabolic cycle, which
    are completely nontoxic to the body. Approximately 45 percent of any
    ingested PG is excreted directly from the body and never even comes into
    contact with the liver. The elimination half-life for propylene glycol
    is approximately four hours, and there is no bioaccumulation (buildup
    in the body over time). A few rare incidents have occurred where a
    person ingested a large quantity of propylene glycol and suffered some
    liver and neurological effects as a result, but these were short-lived
    and subsided once the material was metabolized and excreted.

  • Johnandchristo

    Hi Shawna,

    I have had organic beer. I think it was Samuel Smith also, but the lager not the stout. I loved it, very hoppy. Just for the heck of it, any beer brewed according to the German purity law, ” Reinhotzgabot ” can only have barley, hops, yeast, and water so those are good ones too. They taste good anyways ;)

    ( I know I spelled Reinwhateverbot wrong )

  • Shawna

    Looks like we’ll have to resort to “organic beer”.. I actually just had one a few weeks ago that I LOVE LOVE LOVE.. It’s a stout, which is generally too much for me but the flavor is SO good, in my opinion, that I found if I drink 1/3rd of it each day it is perfect..

    It’s “Samuel Smith’s Organic Chocolate Stout”. Obviously have to be a chocolate lover to enjoy this beer… :) VERY chocolate tasting… And at almost $4.00 a bottle you won’t have to worry about becoming addicted to it ;0)…

  • Shawna

    Interesting that you bring up the PG in ecigs!! Literally JUST yesterday morning a co-worker asked my opinion on the PG in ecigs. My response — “I couldn’t find any damning research data but I am concerned about long term health risks especially at the exposure you are getting” (he gave me exact ml of what he was inhaling). I went on to say “BUT, I would imagine that the damages that might be caused by PG are far less problematic than the damages done by continuing to smoke cigarettes. It’s a trade off but in this case I think the PG in ecigs wins”. :)

  • Shawna

    I would imagine rats have unique biological differences as compared to humans and dogs as well. In fact, one of those differences is the reason why incorrect and potentially harmful data about restricting protein in dogs and cats with kidney disease came about.

    Aimee, one of the contributors on this site, has a saying that goes something like this “eating is risky business”. PG MAY be safe for some, but is it safe for all. My reason for questioning this — some folks have no issue with gluten grains while others develop life threatening and/or debilitating illnesses because of gluten — like neurological (including brain) damage, kidney disease, diabetes etc. Gluten is a “toxin” to those people.

    Dairy is a toxin for me — I have MRI diagnosed brain damage (which I used to believe was due to MSG but now am not sure). I am sure that I am intolerant of and allergic to dairy. In susceptible people it can cause anything from malnutrition to autism to schizophrenia to heart disease and more. My husband gets food poisoning from the lectin proteins in pinto beans if not properly processed.

    If certain foods are problematic, even dangerous, to certain people are you willing to go so far as to say that a man made chemical is 100% safe long term for all those that consume it? I’m not..

  • Johnandchristo

    Did you guys know propylene-glycol is added to Miller Lite? It is and people report GI disturbances from consuming it.

    What exactly is in my beer?Most humans simply are not logical creatures. Even when compared to other animals we seem to be the only ones that frequently engage in harmful behaviors that serve no purpose. When was the last time you saw a cat pushing 120 in his new Porsche? This statement may provide a little clarity to why the most dangerous regulated product consumed by people is the only one that isn’t required to list its ingredients.

    Alcohol companies have successfully lobbied to allow their products to not legally be required to list their contained ingredients. Has anyone questioned this ruling over the years? Of course not! Now some may say that it’s already common knowledge that alcohol has no nutritional benefits. I would respond and either does a microwavable TV dinner, but with the latter at least I’m conscious of the sodium nitrate I’m ingesting. Have you’ve ever wondered how these beverage companies conjure up a brew with their desired flavor and texture. With chemicals of course!

    You think after 50 people died in the 60’s from drinking beer laced with the foaming agent cobalt sulfate the booze industry would have to list their ingredients. Online you can find out that Miller Lite contains propylene glycol alginate, water, barley malt, corn syrup, chemically modified hop extracts, yeast, amyloglucosidase, carbon dioxide, papain enzyme, liquid sugar, potassium metabisulfite, and Emka-malt. That’s more than just hops, water, and yeast. Only God knows what else they’re putting in there!! Beer has been found to contain lupulin, geraniol, Gum Arabic, dextrin, tartaric acid, magnesium sulfate, cobalt, tannic acid, ammonium phosphate, potassium metabisulfite, and sodium hydrosulfite.

    Whether or not these chemicals are harmful to the human body it’s still the FDA’s job to ensure us that we are safe. Currently the ATF is in charge of regulating all alcohol and it’s time someone over their stood up to the powerful corporations. Americans have a right to know what’s going in to our stomachs. Unfortunately voting with our dollars will be much too daunting of a task for most us drinkers because of their greatest ingredient; alcohol. So sit back, pour yourself a nice cold one, write an angry letter to the ATF, than hop in that Porsche and drop it in the mailbox!

    I take 2 puffs on my inhaler every 4 to 6 hours a few days a year, twice a day a few days a year, and once a day a few days a year. That kind of dosage is nothing like someone who smokes an ecig and it is nothing like an animal eating it every meal day in and day out. It’s just not a risk I’m willing to take for an unnecessary ingredient. What positives does PG add to food, that wouldn’t be better gotten from some other source?

  • Pattyvaughn

    Cat pee is more concentrated than dog or human pee usually is but other than that is is not so different.

  • Ryan

    PF was a typo, meant PG. I also forgot to mention that the whole debate whether the PG in ecigs is safe or not can pretty much be concluded by looking at the evidence from asthma inhalers. There is no evidence that PG is seriously harmful even if inhaled daily for decades. PG is also the same substance used in fog machines at rock concerts and such. I vote that it is perfectly harmless, but who knows? Maybe in a few more decades we’ll realize that the long term use of PG over many years causes the onset of some nasty disease, but I find that highly unlikely since asthma inhalers containing PG have been around for about 60 years. If there is a health risk, I believe it’s most likely so small that it is insignificant.

  • Ryan

    About long term effect studies of PG on animals . . . Just read an article that said this was done on lab rats. They were fed a diet consisting of 5% PG daily for 2 years. No side effects were observed. The article was on naturallycurly dot com. It was referenced but I can’t vouch for the validity. Can’t believe everything you read. On the other hand, I can give my opinion from PG intake from personal experience. I have asthma and have been using an inhaler all my life that contains almost entirely PG as have millions of other asthma sufferers for decades. I’ve never heard of any side effects from PF inhalation except for a small percentage of people who are mildly allergic to PG.
    About cats . . . I would guess that they have a very different biology than dogs and humans and that the blood disease that PG causes in cats does not occur in humans or dogs (at least not because of PG intake) because of this biological difference. Again, this is only an assumption, but one only has to take into consideration that cat pee is largely ammonia based while dog and human urine is not.

  • Pattyvaughn

    No, we are pretty much poisoning our environment at an alarming rate, which is why cancer is becoming so prevalent. Even the safest and purest food sources still have environmental toxins in them. And while our air isn’t as bad as China’s, the whole world shares the same source, so even if you live deep in the woods somewhere, you still get to breath pollution, just less of it. You can’t avoid it, but that doesn’t mean you shouldn’t be aware and make the best choices you can. You don’t have to live in fear, but you shouldn’t live in ignorance either.

  • sw01fl

    Wow! Is it safe to breath the air, drink the water or eat anything we buy at the store? And read the labels. Are we to believe everything we read? Or can we safely partake by moderation?

  • mike

    “Have long term daily feeding trials been done with PG?”

    does feeding rats 5% PG every day for 2 years count.

    that study has been done….in 1947.

    it was found to have no noticeable effects.

    be careful what you read on here, there are 2 people citing different ratings on pg from the same environmental working group listing.

    one is even saying that this environmental working group listing shows that it has reproductive issues, and has been linked to cancer.

    both of which appear nowhere http://www.ewg.org/skindeep/ingredient/705315/PROPYLENE_GLYCOL/

    the EWG says this about
    Developmental/reproductive toxicity

    “Not likely to be a toxicant in humans”

    yet people keep spouting this nonsense.

    i suggest that instead of blindly accepting what you read here that you do your own diging.

    From the history that I’ve read it is my understanding that J.D. Searle tried for 10 years to get aspartame passed. Then they hired Donald Rumsfeld as CEO (or CFO or some high other ranking postition) and within the year aspartame was passed.

    I hadn’t heard anything about a “Reagan appointee”, interesting… If memory serves, some FDA scientists that continued to oppose aspartame ended up losing their jobs too (admitedly I may be thinking of another product though? Been a while since I researched all this).

    Sorry! Didn’t mean to step on your toes. Didn’t see this until after I posted. The interesting thing about aspartame is that it had been turned down numerous times until a new Reagan appointee added a sixth member to the board. With a 3-3 tie, he cast the tie-breaker to approve it.

  • Rick

    The FDA is a political organization not a health organization. If you have the right connections you can even get neuro-toxins like aspartame approved.

  • Bob Bamberg

    I agree that we don’t have to fear all chemicals. Ethylene glycol is the main ingredient in antifreeze while propylene glycol is used in “pet-safe” antifreeze. It’s safer (although certainly not totally safe) than ethylene glycol and is only toxic in much higher concentrations. A commenter said that there were reports of dogs fed food containing propylene glycol getting sick and some deaths. The sickness and deaths could be attributed to any number of things. Even high end foods add propylene glycol, and it seems to me that if it were a problem, dogs would be dropping off like flies.

  • LawofRaw

    Cyanide is natural too, and you definitely wouldn’t want to consume that!

    Propylene glycol is definitely a controversial chemical. It is even used in human skin products and rated a category 3 by the Environmental Working Group, which 3, deems it as a “moderate” health issue.

  • Carl Oakley

    Thanks for the information. I did find something that suggests it *may* be safe.
    I found a reference to it at the Agency for Toxic Substances and Disease Registry. They list it as non carcinogenic and used as an antifreeze when leakage might cause contact with food among other uses. The article can be found here.
    http://www.atsdr.cdc.gov/substances/toxsubstance.asp?toxid=240
    I found a few other articles, EHow and Wikipedia to name a couple, but I don’t consider them to be reliable. ATSDR, however seems to be a creditable source.

  • Shawna

    Yes, my example was regarding aspartame in an attempt to demonstrate that a GRAS classification really isn’t a guarantee that something is truly “safe”.

    However, that said, I too don’t find a lot of negative data on PG. But, like Mike, I am concerned about long term affects? The FDA says it is completely safe to feed dogs small amounts of pento too.. However the US Fish & Wildlife says it is a poison and should not be rendered into animal feed.. Have long term daily feeding trials been done with PG?

    All that said, I’m really a food snob. I prefer foods, preservatives etc that are made by nature not in labs (this includes synthetic and even isolated vitamins and amino acids). Sometimes exceptions have to be made due to budget or other reasons but I want the food that is the most natural be it raw (which I primarily feed), canned or kibble.

  • Carl Oakley

    I’m just curious here. Are you speaking of adverse effects of Aspertame or PG? If PG, I haven’t been able to find many adverse effects. Some few people seem to be mildly allergic to it, but other than that, and the adverse effects on cats, I can find no adverse effects. As for it being a chemical, sure. So is water. Just because something is a chemical doesn’t mean it’s necessarily bad for you. Just trying to understand here.

  • Pattyvaughn

    Me either!!!

  • Shawna

    There are a lot of “foods” and addatives that are classified by the FDA and GRAS. Doesn’t make them “safe” however — take aspartame as an example.

    “From all the adverse effects caused by this product, it is suggested that serious further testing and research be undertaken to eliminate any and all controversies surrounding this product.” http://www.nature.com/ejcn/journal/v62/n4/full/1602866a.html
    I have no trust a GRAS classification..

  • Pattyvaughn

    You’re preaching to the choir on this one. I don’t eat processed garbage and I said that ecigs were the best use for PG that I have ever heard of. PG is also used to dilute oral meds. I prefer to just stay healthy in the first place.

  • Carl Oakley

    You don’t want it in your food? Sorry, it’s added to many human foods as a food additive and has been classified by the FDA as “Generally Recognized As Safe”. It’s also used to dilute medications for injection that are not soluable in water. I’m not saying it’s safe (it obviously not for cats), I’m simply reporting the facts.
    And as for electronic cigarettes, I don’t see how inhaling propylene glycol vapor can be more harmful than all those tars and other nasty chemicals.

  • Cyndi

    Well good for you, but I am STILL proud of myself! I may still be smoking nicotine, but atleast I’m not still smoking the 5 million other poisons that are in real cigarettes, and THAT is a good thing. Some people aren’t as strong as you are & can’t do it cold turkey. I need to do it gradually, which I am.

  • http://www.wtf.me.pn/ rewwssfgg

    Well I don’t think you want salt in your radiator any more than I want to eat antifreeze. Salt in really any dose that isn’t already naturally in the food is also bad for pets. Bad for people too however our bodies have a great deal of saline in our bodies. Mammals use salt but mammals don’t drink or eat propylene glycol nor does our body use it nor produce it like we do with salt.
    It’s basically a filler that is not needed nor is it “Natural” being it takes human manipulation to create it.
    It is not approved for use in Cats because it can cause life threatening illness. It also still has a sweet flavour which can attract cats or dogs to drink it.
    It is still considered poisonous to dogs and cats but at High levels. Eating it everyday can’t be good I wouldn’t feed it to any dog I had. There have been reports of people feeding their dogs with that added to the dog food made the dogs sick, some died and others got better after changing the food to non PG added brands.

  • http://www.wtf.me.pn/ rewwssfgg

    I quit cold turkey and didn’t need more poison to help me quit..If someone wants to smoke antifreeze go ahead..
    The fact is you haven’t quit smoking because you rely on Nicotine to be burned and put in your lungs and you exhale the smoke from the e-Cigarette..
    I smoked as much as you..3 years..never looking back..

  • Pattyvaughn

    Depending on the breed of dog, 12 years is not as old as you think. The old 7 dog years for every 1 human year is an average at best and flat out wrong because you can’t compare how dogs age to how humans age at worst.

  • Brandon

    You put a dog to sleep at 12 years of age? That’s a long life for a dog. Are you going to be flabbergasted when a human dies at 84? Your dog was old. That would be a different story if you had to put a 4 year old dog to sleep.

  • Pattyvaughn

    Oh absolutely, you should keep a glass of the most toxic in the fridge so it will be refreshing as you drink it down yourself, maybe even pour it over ice.

  • Doofus

    Thank you. Now I know I need to find antifreeze with ethylene glycol to soak food in.

  • Cyndi

    I tried to go cold turkey, but the nicotine withdrawal was horrible! They have different strengths of nicotine in the ecigarette liquid. I am on the medium now, so hopefully soon, I’ll be done with them.

  • Pattyvaughn

    Everyone I know who quit smoking said that finding something to do with their hands was one of the biggest hurdles. One of my friends took up doing slight of hand tricks, because its one of those things you have to practice until you can do it without thinking to get it right. It really worked for her. Good luck on your last little bit, you’ve done the worst part already, so I know you’ll be successful.

  • Cyndi

    I agree! & Thank you! :) I NEVER thought I would be able to quit smoking! I smoked between a pack and a half and two packs a day for almost 31 years! These ecigarettes have been a godsend for me. I am starting to ween myself off of them and then I will be done for good! Yay me! :)

  • Pattyvaughn

    Then that is the best use I’ve heard of for PG!! Congratulations!! They also use it in some liquid medications to cut them to the proper strength.

  • Cyndi

    I haven’t done any reading on propylene glycol, but that is one of the main ingredients in those Ecigarettes. I am currently using those and smoke them daily. If it wasn’t for those, I wouldn’t have been able to quit smoking the real cigarettes. I smoked my last one just about 3 months ago. :)

  • Shawna

    Interesting post.. MY brain damage was diagnosed via MRI (most of the regulars here on DFA know I have brain damage due to free glutamic and aspartic acid — I’ve mentioned it here before). By the way I was a smoker for about 15 years before the diagnosis…. So cigs don’t help that much.. At least not at a pack a day.

    “Glu” IS present in protein as you mention. All bound up with other amino acids. NOT isolated.. The problem is not “glu” it is the way it is processed and “freed” and the large amounts consumed in processed foods. MY information, in part, came from Neurosurgeon Dr. Russell Blaylock’s book “Excitotoxins: The Taste that Kills”. I own the book if you’d like to read it. Or, you can get the electronic version on Amazon. http://www.amazon.com/Excitotoxins-Taste-That-Kills-ebook/dp/B003X4M6PC/ref=tmm_kin_title_0

    And yes, by the way, I do suggest limiting the diet of foods with freed glutamic and aspartic acids. Especially if the person/pet has or has had hypoglycemia, brain injury etc.

  • http://www.facebook.com/ryan.gambord Ryan Gambord

    Glu is a well-known excitatory molecule that causes neuronal death when applied to brain cells in-vitro. I’ve done this myself and watched it happen. Nicotine strengthens the myelin sheath neurons in-vitro (done this myself too). Glu is present in all protein containing foods, so I suppose you propose we stop eating… food? I guess you’re right, we should stop eating food, and start eating cigarettes.

  • Hound Dog Mom

    “According to the Environmental Working Group, propylene glycol can cause a whole host of problems. It is rated a 4 by them, which is categorized as a ‘moderate’ health issue. It has been shown to be linked to cancer, developmental/reproductive issues, allergies/immunotoxicity, neurotoxicity and endocrine disruption. It has been found to provoke skin irritation and sensitization in humans as low as 2% concentration, while the industry review panel recommends cosmetics can contain up to 50% of the substance.” [The Good Human]

    Hmm…if propylene glycol carries these risks when in human cosmetics, imagine what eating it day after day would do to a dog? BTW – propylene glycol is banned from cat food because it causes Heinz body anemia. I agree with Patty – this is a chemical, not a food. Any substance that is created in a lab doesn’t belong in food.

  • Pattyvaughn

    That is so true, but why should we want propylene glycol in our dogs food. I don’t want it in mine either. It is a chemical, it is not food.

  • http://twitter.com/neandervalley Ana Banana

    propylene glycol is used in antifreeze because it helps lower the freezing point of water. you know what else has antifreeze properties? salt. should we ban it from all foods?
    Just because something is used in a toxic product does not mean the product itself is toxic. likewise, just because something is safe and “natural” does not mean it can’t cause harm. case in point: even excess water consumption can kill, and dirt and poop are natural but I wouldn’t want to eat them.
    we don’t have to fear all chemicals…

  • http://www.theholisticchatterbox.com/ Shawna

    I think your research skills may be a bit lacking. It is EASY to find research on the damages of MSG and aspartame.

    ” We demonstrated that (1) Treatment with MSG induces a dose-dependent swelling and death of mature neurons” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2802046/ (aka KILLS brain cells.)

    From the Annals of Neurology

    “Information obtained over the past 25 years indicates that the amino acid glutamate functions as a fast excitatory transmitter in the mammalian brain. Studies completed during the last 15 years have also demonstrated that glutamate is a powerful neurotoxin, capable of killing neurons in the central nervous system when its extracellular concentration is sufficiently high. Recent experiments in a variety of preparations have shown that either blockade of synaptic transmission or the specific antagonism of postsynaptic glutamate receptors greatly diminishes the sensitivity of central neurons to hypoxia and ischemia. These experiments suggest that glutamate plays a key role in ischemic brain damage, and that drugs which decrease the accumulation of glutamate or block its postsynaptic effects may be a rational therapy for stroke.”
    http://onlinelibrary.wiley.com/doi/10.1002/ana.410190202/abstract

    The “wood grain alcohol” in aspartame is just as damaging as the free aspartic acid..

    If that isn’t enough though, this research paper discuses glutamate AND aspartate

    “Glutamate and aspartate also caused glial and neuronal changes in other periventricular structures, e.g., septum, hypothalamus, caudate and habenula, as well as in the most dorsal portion of the cerebellum. Dendritic swelling induced by glutamate and aspartate in the cerebellar molecular layer was accompanied by acute necrosis of Purkinje cell somata. These results suggest that seizure-associated brain damage is initiated by excessive endogenous excitatory amino acid receptor activation.”

    People who follow this site religiously, should be directed to report their testimonials within the proper channels. There is much hate, anger and frustration directed to a dog food FB page. It is sad to see them persist, with no results. People who are experiencing no problems are panicking. They need to be directed to the FDA and Dept. of Agriculture, or their own attorney. The way they are going, they will be lucky if the company doesn’t sue them.

    As for the claims below, regarding MSG and Aspartame…I can find no evidence of danger. Studies, in fact, point the opposite way.

    Poppy211,

    As I mention in my article, although propylene glycol is less toxic than ethylene glycol, the fact remains that the compound is still at least controversial.

    That’s because the FDA has stated, “According to the FDA “It was known for some time that propylene glycol caused Heinz Body formation in the red blood cells of cats (small clumps of proteins seen in the cells when viewed under the microscope), but it could not be shown to cause overt anemia or other clinical effects. However, recent reports in the veterinary literature of scientifically sound studies have shown that propylene glycol reduces the red blood cell survival time, renders red blood cells more susceptible to oxidative damage, and has other adverse effects in cats consuming the substance at levels found in soft-moist food. In light of this new data, CVM amended the regulations to expressly prohibit the use of propylene glycol in cat foods.”

    Unlike most human foods, commercial dog foods tend to be fed continuously, twice each day, 365 days each year. For this reason and in addition to the fact propylene has been banned from use in cat food (for safety reasons), we still feel compelled to remind pet owners they should avoid products containing propylene glycol.

    PROPYLENE GLYCOL

    The truth about Propylene Glycol

    In chemistry ingredients are often known by more than one name. Examples are “glycerin” whose chemical name is usually referred to as “glycols” because there is more than one form of them. Glycerin and glycol are the same thing. Glycols, or glycerin’s are combinations of sugars and alcohols. In chemistry nomenclature all carbohydrates are known as “sugars”. But the word “sugars” does not refer to what most people think of when they hear the word “sugar.” What people sometimes misunderstand is that they mistakenly believe the word “sugar” is what they think of as “table sugar”. Like you use to sweeten your coffee, tea, or other foods. Actually that type of sugar is actually “sucrose”. Whereas to a chemist the word “sugar” refers to any carbohydrate, even dextrin’s, starches, celluloses or any other carbohydrate.

    Many people, falsely claim to be experts on the subject, claim that propylene glycol is used in “anti-freeze’. What they don’t tell you, probably because they don’t know the difference, is that propylene glycol is used as an anti-freeze in fruit juices, beer, and other liquid foods. Anti-freeze in automobiles or cars is usually “methylene glycol” not “propylene glycol”. Methylene glycol is used in cars because it is much cheaper and it would be toxic ingested orally. The alcohol used in it is “wood alcohol (methanol)”.

    Propylene glycol is used in liquid foods because when ingested orally it is converted in your body to “pyruvic acid (blood sugar)” and 5% acetic acid” which is usually known by most people as “vinegar”. They are the same thing, the word “vinegar” is the common name. The word “5% acetic acid” is it’s chemical name”, they are the same thing.

    Since “Pyruvic Acid” is “blood sugar” which is absolutely necessary for life to exist, both chemicals are harmless. You could drink it start by the pints or even gallons without any problems, other than increasing your blood sugar. That’s why it is used in food liquids.

    As you state propylene glycol being both “water” and “oil soluble” it serves to be the “coupling agent” to mix water and oil together which normally will not mix without using it. That’s how it keep the ingredients from separating.

    Also the alcohol part of propylene glycol serves to act as an anti-bacterial and anti-fungal. It is an excellent natural preservative, which has the extra benefit of being totally safe for internal use.

    There are many false statements that some people have mislead about. Actually the chemicals found in propylene glycol are common in most foods we consume in a normal diet everyday. To say that they are dangerous to our health is ridiculous. God would not have put them there if they were bad for our health.

    My sweet pup had just turned 12 when we put her to sleep over a yr ago – due to chronic kidney disease, which I shall always believe was caused by all the years of feeding her Purina Beneful – due to my trust in the ‘great Purina company’ and my own stupidity! This was a dog that was never sickly, until the symptoms really showed up the last year of her life. Jessie and our 2 cats had always been fed Purina products – and all 3 of them, as it turns out, always shed like crazy – another thing I never gave too much thought about. Long, sad story short – I’ve switched our pets (a rescued puppy joined our home recently) to Blue Buffalo after much research and seeking advice from reliable people. BENEFUL CONTAINS PROPYLENE GLYCOL as one of its main ingredients – SHAME ON THEM!

    The rule of thumb is that milk chocolate is considered toxic at 1 oz of chocolate per pound of body weight. Dark chocolate is stronger and bakers chocolate worse still. I don’t want my dog to develope a taste for it, so we have a zero tolerance policy. We make homemade candy so always have loads of the stuff around. We keep it in plastic containers in a closed pantry.

  • Hound Dog Mom

    DogLover,

    Whether or not chocolate will prove toxic to your dog depends on both the your dog’s weight and the type of chocolate. The darker the chocolate the more toxic (white chocolate is not toxic). Also larger dogs would have to eat a rather large quantity of traditional milk chocolate to cause issues. When I was a kid I had an 85 lb. german shepherd, she got into my easter basket one year and ate everything (including my rather large milk chocolate rabbit) – nothing happened to her. I also know of someone who had a golden retriever, they were baking chocolate chip cookies and left the room, the dog got onto the counter at half a bag of semi-sweet chocolate chips and died.  I would STRONGLY advise against voluntarily feeding your dog chocolate, it’s not worth the risk.

  • DogLover

     I have a serious question about the “chocolate is bad for dogs” thing.  My miniature dachshund ate it all her life, we didn’t know it was “toxic to dogs” back then.  Now, we did not feed it to her daily or in large quantities, but just a nibble every now and then.  She lived to be 17 years old.

But second, I got another e-mail saying that PG is not antifreeze, that it is not harmful and that it is used in many products, including cookies. Therefore, they said, it is safe for my dog. I have seen multiple reports of it being unsafe. This really bothers me that it is still being used on the market when there are other alternatives! Why are we killing our pets and ourselves?

    The FDA doesn’t work that way. It’s banned in cats because there were dramatic, documented reactions. The PPG poisoning in other species acts differently. The FDA requires a different “warning proceedure” for slower, less well defined toxic reactions. It first requires that consumers make the connection them selves, and file a complaint. Enough complaints must be filed, with an assigned dollar value to accumulate sufficient funding to run 10 trials before a fact finding declaration in filed. Then following the required red tape, hearings and appeals by manufacturers, the “warning” may be issued. That s the government process. It typically takes 20 years or more for factual evidence to be proclaimed by the FDA.

    I don’t wait on them. I rely on credible science. And it says PPG is an accumulatory toxin in all life forms.

    You really think the FDA is more concerned with the welfare of cats than people? PPG is banned in cat food because it causes a reaction which only occurs in cats. Propolyne glycol, along with all of the other unrecognizable ingredients are there because they’re cheap and create an end product which can be sold for much more than the cost to produce. Not saying its completely safe, but is anything completely safe these days? Cows are being pumped full of hormones and antibiotics, fed corn when they should be eating grass, and plants are grown with chemical pesticides and fertilizers. The big companies have gotten into the “organic” market too, and the term is so broad, that it basically has no meaning.

    From what I have read, small quantities only cause health problems in cats. One chemical can be safe for one species, but toxic to another. Dogs shouldn’t eat chocolate; does that mean chocolate isn’t safe for human consumption?

  • Kikib127

    Propylene Glycol is in almost everything humans consume that is listed as “flavoring”” on the ingredients. Cake icing, suckers etc. Also in body lotion, make-up, soaps, asthma inhalors, variety of baby wipes and e-cigarettes

    How is Propylene Glycol Made?
    -Crude oil is made into Petroleum Naptha-Petroleum Naptha is made into Propylene-Propylene is made into Propylene Oxide-Propylen Oxide is made into Propylene Glycol
     Technically PG is a derivative of a petroleum product, but it is so far removed that the petroleum characteristics are not apparent.
    It is well proven that large doses of pure Propylen Glycol are necessary to induce a toxic response, for dogs, doses in the range of 9ml/kg are nessesary to induce toxics effects, thats 9ml of pure Pg in one KG of blood, to reach blood volume levels of 9m/kg would require a massive amount of PG to be ingested all at once by the dog, other animals in lab tests required levels in the 20ml/kg for toxic effect to occur.
    PG is one of the safest food additives in existence and has over 50 years of scientific data to prove it, it’s not the one you need to worry about.

    While propylene Glycol is approved for use, that is not the same as “safe” or “healthy.” MSG is approved for use in human food, is on the FDAs GRAS list and it is an excitatory neurotoxin. It’s proven to kill brain cells. Aspartame, (now labeled Neotame) is highly toxic. It’s also “approved.” it is an excitatory neurotoxin and causes tumors. Both cause obesity.

    Propylene Glycol is a petroleum derivative. Would you feed your animals crude oil, or gasoline? Even a little, with every meal?

  • slojas

    Is propylene glycol used in pet food safe for all animals?
    Propylene glycol is an approved feed material. However, whilst it is safe for use in cattle, dogs and poultry it shall not be used in cat feed.  When fed with propylene glycol containing feed, cats show an increase in Heinz body formation, which are deformities of erythrocytes and shorten the life time of the red blood cells. This is unique to cats.

    Waggin Train Treats do not contain propylene glycol.  However, if you have been feeding the chicken jerky treats, you do have reason for concern.  While there hasn’t been an official recall, there was a warning issued by the FDA in 2011, Nov?, regarding Chinese chicken jerky treats.  They have received hundreds of reports of illness linked to them and in some cases death.  Waggin Train was one of 3 companies identifies by the FDA as “possible links” to the problem treats.  They haven’t pinpointed the specific contaminant.  Kidney failure is being seen.  There are some good articles on here for you to read. 

  • Roslynmeadows

    My 2 pound, 14 month old yorkie Gigi is in kidney failure as I write this…..has there been any connection with waggin train treats and propylene glycol?

  • Gordon

    Yep Toxed, Australian don’t have a 1st amendment in our constitution like yous do. “The right to bear arms” if I got that right?

    And our gun laws got even tougher since 1997′s – now world’s second biggest lone gunman mass murders (The biggest one being the recent one in Norway), of Port Aurthur in Tasmania.

    And subsequently our stricter laws were able to overcome the country’s gun lobby, contrary to your own powerful gun lobby which has to date, been able to stave off any significant restrictive gun laws. At least, to my knowledge. Happy to be stood corrected? But the point is, yes you’re right, Australia has a much greater restriction re gun laws than the US.

    Debbie, I’m sorry to read about your dog’s death too. You are right. “Less toxic” is still toxic. That is so sad!

    Gordon, “You hit the nail right on the head!” There is no need for all those toxins in our consumer products. There are non-toxic or safer alternatives for just about everything. Until manufacturers start listening, as consumers, our best choices are organic and additive free. Raising our own and hunting are still better than CAFO or processed meats. You’re also right about this being “right up my alley.” This is where I live. :-)

    (Yeah, I always wanted to live in Australia :-D … But my husband is a hunter and heard you couldn’t have guns there.
    :-( Besides, I just couldn’t eat kangaroo! Too cute!)

    Having that knowledge certainly helps in evaluating dogfood and it’s processing. But what I keep learning is that there are always more layers of “the onion” to peel. I only feed raw scrap from our own livestock or game and dehydrated liver treats as treats to our dog, or a 5 star kibble as training treats. I had never read a soft dog treat package and didn’t even realize they were putting PPG in there! I always tell people, Read the Label! If you don’t recognize it as regular food, don’t eat it and don’t put it on your body!

  • Gordon

    Sorry to read about your loss, Debbie.

    These articles would be right up your ally, Toxed, re these questionable additives to commercial dog food. Let me rephrase that….these and many other questionable and toxic additives found not only in dog foods, but even so called whole fresh fish re mercury, and raw meats containing sulphur dioxide, hormones and antibiotics, even.

    That’s why it’s always best to try and seek certified organic where possible. Failing that, hunt for game oneself, lol.

    I’m probably still a little more lucky in that in Australia, I can sill obtain more prevalent grass fed and drug free raw meats, than maybe the US.

  • Debbie

    I just had a dog die from propylene glycol poisoning. She apparently got into it after my husband was done servicing a solar hot water system. The vet even suspected poisoning but when I brought up ppg she said “oh that wouldn’t have caused this” THINK AGAIN, just because it is less toxix than peg doesn’t mean it isn’t toxic!!!!!!!!!!!

    I don’t care when it was originally written! I just read your post today and greatly appreciate the your professional input! I say, Thank goodness you posted!

    Sorry Mike! I see the first post was Dated Jan. 2010. Is that when this was written?

  • http://www.facebook.com/Toxed2loss Toxed2loss

    Hi Mike,
    I LOVE this article! I am so glad you raised this important issue. I have certifications in PPG & PEG poisoning from CDC. So I can actually say I am an “expert” on this. I hope you don’t mind my making a few clarifications. PPG is just now becoming an anti-freeze product, due to the number of poisonings from PEG, antifreeze. PPG is tons LESS toxic than PEG. However, that doesn’t invalidate any of the things you listed as concerns. :-)

    Mainly Accummulative effect. It is toxic, and persons or animals can become extremely reactive to it. The CDCs monograph on it says that it’s not toxic enough to warrant concern for dermal and respiratory vectored poisonings, unless your reactant to it.

    Did you all get that? (sometimes I don’t communicate clearly, so I’ll restate it bluntly…) It is toxic if accumulated to a high enough level, primarily by ingestion but even by transdermal and respiratory routes! “High enough level” is determined on a case by case basis, as each individual is different, in so many ways!

    So, re-read agostine’s post specifically for topicals. He’s extremely well informed, except for the ice cream thing. It is used in some ice creams and it doesn’t have to be on the label due to US Code of Federal Regulations concerning milk and milk products when used as a “thickening agent” to enhance consumer appeal…. Bet that floors ya’. Did me too!

    Moving along to Jason’s comment… PPG is used a lot in veterinary medicine. PPG is a petroleum based synthetic sugar. It is toxic, wether you feed it or inject it or trowel it on. You won’t notice anything that you can connect to it with random application. It will, however, still depress your critters immune response. My vet told me to use this, straight, for sheep that were experiencing pregnancy toxemia, with the caution that no more than x amount, or it will kill ‘em. (I used stock molasses instead. Hid response, “that will work.”)

    Interesting that they know it’s toxic but figure there’s a lower limit that’s the same for every critter. Food for thought….

    I would just like to note that, in addition to the existing propylene glycol content in some foods, some wormers require dilution using propylene glycol. So that is even more they are ingesting. I’m not 100% sure, but I believe long term effect of ingestion can lead to blindness amongst other things. I personally use Ivermec which uses propylene glycol as the diluting agent, but I feed a raw natural diet. This way I know exactly what my dog is eating, and if / when I need to pinch pennies and use a kibble, I use Blue Buffalo. It does not contain many of the known harmful ingredients which so many others do.

  • agostine

    Propylene Glycol doesn’t just exist in ice cream. It is in many baked goods, it is the basis of many artificial flavorings, it is in cake mixes, it is in salad dressings, it binds artificial flavoring to coffee beans, it’s a foam stabilizer in many beers…
    So it doesn’t matter if you don’t eat a tub of ice cream daily, people are consuming PPG. Beyond that, it is an ingredient in most topical creams, make-ups, soaps, hair products, cleaning products and medicines. So it is not just about a gel cap or two here and there. I know, because I am allergic to PPG and I can assure you it is nearly impossible to eliminate it because it is in EVERYTHING! Even so-called “natural” products. While PPG may be deemed safe in small quantities, it is the cumulative effect of all the products that it is in that concerns me.

  • Joseph LattaTorres

    I think that if its bad for cats it should be just as bad for dogs and people. I think that if these people who think its ok for dogs and people to ingest this chemical they themselves should be more than willing to consume reasonable amounts of this chemical and see what they long term effects are.

  • Meagan

    I was not aware this was used in moist dog treats, but I will definealty be watching for it now.

  • citygirl

    Let me tell you something. If you can get it in a supermarket, it is NOT good pet food! Learn to read labels, learn what those ingredients actually are. Check out your local pet feed store, where they cater to the better brands. And no, more expensive does not mean THE BEST. There are a few out there that are in the middle price bracket that I still would not feed to my dogs, and they call themselves Premium. You still spend the same amount of money, because the cheap crum is fillers that your dog poops right out again. Then you buy it again in a week. Get the ultra-premium foods, and you buy LESS and without all of the added gunk. Same money spent.

  • Angela Griede

    You can say small amounts of glycol in food for people or dogs is safe..I don’t believe it..thats nice to know that the FDA banned it in cat food, but what about dogs and people?
    Don’t think somebody isn’t out there to slowly kill us with poison. We need to wake up and pay attention.

  • http://DogFoodAdvisor.com Mike Sagman

    Hi Terry… Your point is well-taken. However, infants don’t eat baby wipes. And most of us don’t consume a meal-size chunk of ice cream twice a day, every day, seven days a week, 365 days a year… year after year.

    I’m never concerned about an occasional “dose” of most food additives. It’s when consumption becomes chronic that I worry. Like I said in the article, “no matter how safe this stuff may seem, it’s the continuous, day-after-day feeding of this controversial chemical that worries” us.

  • Terri

    you should also be checking your favorite human food labels. propylene glycol is used in human foods & baby wipes! Check the label of your favorite ice cream. If the FDA has banned in cat food why are they allowed to use in our food?

  • http://DogFoodAdvisor.com Mike Sagman

    Karen… your point is well-taken. However, we’re talking species-specific and dose-specific toxicity here. Using PPG in larger doses (not as an excipient in human medications but as a humectant in pet food) can present greater toxic risk to dogs (especially at doses exceeding 9ml/kg). And PPG is even more toxic to cats.

    By the way, dog food manufacturers do not publicly inform buyers regarding the actual amount of PPG in the food.

    Dogs and cats are significantly more sensitive to (the toxicity of) PPG than humans. As I stated in my article… “No matter how safe this stuff may seem, it’s the perpetual daily feeding of this controversial chemical that worries me.” Chronic ingestion of any toxin on a steady, long-term basis can have greater impact on a pet’s health than just occasional ingestion.

    OK, maybe some human medicines require PPG as an excipient (a therapeutic “carrier”)… but no dog food ever “needs” PPG for anything of vital importance. So, why take the risk?

  • karen

    If you are having trouble with PEG, and PPG in dog foods, you need to check your gelcap medicines and supplements. All contain these as an excipient. That’s the stuff that they use to keep the active ingredients soluable. Good luck finding a form that can be digested any other way…..other than eating them in FOOD! :-) Food, the ultimate excipient! hehehe

    Hi, Mike.

    Great information. Readers should know to be as diligent in checking labels on treats and chewies as they are in shopping kibble and canned foods.

    Glycol is high on the list of ingredients of most soft (i.e., moist) training treats.

    I couldn’t believe it when I first noticed this. I had to look around me to make sure I hadn’t walked into an auto parts store by mistake.
