同義語： Ascorbyl Tetraisopalmitate, VC-IP, Tetrahexyldecyl Ascorbate, Esterified Vitamin C, Lipid-Soluble Vitamin C, Ascorbic Acid Tetra-2-hexyldecanoate, Vitamin C Tetraisopalmitate, Ascorbyl Tetra-2-hexyldecanoate

Ascorbyl Tetraisopalmitate (VC-IP) is a highly stable, oil-soluble derivative of L-ascorbic acid (vitamin C). It is formed by esterifying the four hydroxyl groups of ascorbic acid with isopalmitic acid, resulting in a lipophilic compound that is chemically stable and resistant to oxidation—a major advantage over conventional water-soluble ascorbic acid.

This structural modification enables superior penetration into the stratum corneum and deeper skin layers, where it is gradually hydrolyzed to release active vitamin C. As a result, VC-IP provides the full spectrum of vitamin C benefits—antioxidant protection, collagen synthesis stimulation, and melanin inhibition—without the instability, irritation, or formulation challenges associated with traditional ascorbic acid.

Ascorbyl Tetraisopalmitate is widely used in premium skincare and cosmetic formulations, including serums, creams, lotions, and sun care products. Its compatibility with oil-based systems and its heat stability make it a preferred choice for formulators seeking stable and effective vitamin C derivatives.
