Some say it’s safe. Yet others believe the dog food preservative… propyl gallate… may be responsible for causing a number of serious health problems.
That’s because of the chemical’s unusual ability to mimic the negative effects of the female hormone… estrogen.
Although research has found the additive to be safe… recent studies have linked propyl gallate with a special group of hormone-like compounds known as xenoestrogens (zee-no-es’-tro-jenz).
Xenoestrogens have the potential to adversely affect reproductive health. In humans, they have the ability to turn a normal breast cell into a cancer cell.
Propyl gallate can also affect a developing fetus… as well as decrease the sperm count in males.
Any way you look at it… feeding a dog the same chemical additive… not just occasionally… but with every meal… certainly favors the creation of problems associated with long term exposure to any toxic substance.
My recommendation? Whenever you spot propyl gallate on a dog food label… step aside. Look for a safer naturally-preserved product.

So, why is this ingredient included in foods? Is there supposed to be some benefits (according to the food manufacturers), or is it a by-product of overly engineered protein sources? Thanks.
Hi Janet… As hard as it is to believe, propyl gallate is still used as a fat preservative in some dog foods.
