Description
Octyl gallate (E 311, Progallin O, PPC 17, NSC 97419) is a gallic acid ester with CAS number 1034-01-1, approved as a food antioxidant under EU regulation. It belongs to the alkyl gallate family and is registered under EC 213-853-0 with HS code 29182900.
In food and edible oil formulations, octyl gallate retards lipid oxidation by donating hydrogen atoms to free radicals, interrupting the oxidative chain reaction. In cosmetic and personal care products, it functions as both an antioxidant stabilizer for emulsions and a UV absorber, protecting formulations and skin lipids from photo-oxidative degradation.
Octyl gallate is available in food-grade and cosmetic-grade specifications, compliant with EU E 311 provisions, FCC standards, and REACH registration requirements. It is supplied in standard fiber drums and multi-layer bags. Procurement teams should confirm grade suitability against Ph.Eur. monographs when targeting pharmaceutical applications.
