Description
N-Propyl Gallate (CAS 121-79-9) is a propyl ester of gallic acid, approved as food antioxidant E310 and sold under trade names including Tenox PG, Progallin P, and Nipa 49. It is registered under FEMA 2974 for flavour applications and carries EC number 204-498-2.
In food and nutrition, N-Propyl Gallate retards oxidative rancidity in fats and oils by scavenging free radicals, extending shelf life in products such as edible oils, chewing gum, and meat products. In personal care formulations, it functions as a UV absorber and antioxidant stabiliser, protecting lipid-based emulsions and fragrance compounds from photo-oxidative degradation.
This material is available in food-grade and cosmetic-grade specifications, with compliance to FCC, Ph.Eur., and EU Regulation (EC) No 1333/2008 for E310 use. It is fully registered under REACH (HS code 29182950) and typically supplied in fibre drums or multi-layer bags.
