Propyl gallate, or propyl 3,4,5-trihydroxybenzoate is an ester formed by the condensation of gallic acid and propanol. It is an antioxidant added to foods containing oils and fats to prevent oxidation.[citation needed] As a food additive, it is used under the E number E310.

Propyl gallate is an anti-oxidant. It protects against oxidation by hydrogen peroxide and oxygen free radicals, in a catalytic manner similar to superoxide dismutase.

Propyl gallate is used to protect oils and fats in products from oxidation.

It is used in foods, cosmetics, hair products, adhesives, and lubricants.

It is used as a triplet quencher in fluorescence microscopy.

Recent studies found this compound to mimic estrogen similar to other xenoestrogens. This may result in male organisms developing female traits. Increased estrogen load is often associated with increased risk of developing cancer in estrogen-sensitive tissues such as ovary, breast, prostate, etc.
