Propyl gallate is an antioxidant that prevents the oxidation of foods containing oils and fats.

Health considerations

A 2009 study found propyl gallate to be a potential xenoestrogen capable of disrupting the effect of estrogen in the body. Consumption of propyl gallate has also been associated with stomach and skin irritability in addition to allergic reactions. The European Food Safety Authority completed a review of propyl gallate in 2014, concluding that propyl gallate had uncertain health effects but was not of concern at the level of reasonably expected consumption.
