(±)-α-Tocopherol acetate(CAT: I038801) is a synthetic, stable form of vitamin E composed of a racemic mixture of α-tocopherol esterified with acetic acid. This modification protects the antioxidant activity of α-tocopherol, enhancing its stability and shelf life. Once absorbed, it is hydrolyzed to free α-tocopherol, which functions as a potent lipid-soluble antioxidant, protecting cell membranes from oxidative stress and lipid peroxidation. Widely used in dermatology and nutritional supplements, it supports skin health, promotes wound healing, and combats inflammatory conditions. Its antioxidant properties also make it valuable in pharmaceutical and cosmetic formulations for protecting cells from oxidative damage.
