Propyl gallate, or propyl 3,4,5-trihydroxybenzoate is an ester formed by the condensation of gallic acid and propanol. Since 1948, this antioxidant has been added to foods containing oils and fats to prevent oxidation.[1] As a food additive, it is used under the E number E310..Propyl gallate is an antioxidant. It protects against oxidation by hydrogen peroxide and oxygen free radicals.
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 state quencher and an antioxidant in fluorescence microscopy
