Overview
Ascorbyl palmitate is an ester compound formed by the esterification of L-ascorbic acid with palmitic acid, serving as a highly effective lipophilic antioxidant. The ester bond at the 6-position hydroxyl group preserves the antioxidant active center of vitamin C while conferring lipophilicity, enabling uniform dispersion in oil systems and sustained antioxidant activity.
