Ascorbyl Tetraisopalmitate
What is Ascorbyl Tetraisopalmitate?
Ascorbyl Tetraisopalmitate is a synthetic, lipid-soluble ester formed by attaching four isopalmitic acid chains to ascorbic acid, the core structure of vitamin C. This chemical modification boosts its stability against oxidation and light, unlike pure ascorbic acid, and enables solubility in oils for use in emulsions, serums, and creams. In cosmetic products, it serves in the antioxidant category to help protect formulation integrity and skin from environmental stressors, while functioning as an emollient to soften surface texture and a skin conditioning agent to enhance flexibility and moisture retention. Its lipophilic nature allows deeper penetration into the skin's outer layers, supporting its role in various skincare routines focused on conditioning and protection.
