    Ascorbyl palmitate More Info

    Ascorbyl palmitate (6-O-palmitoyl-L-ascorbic acid, CAS 137-66-6) is an ester formed by combining ascorbic acid (Vitamin C) with palmitic acid, a saturated fatty acid . This produces a stable, lipid-soluble (oil-soluble) form of Vitamin C that is suitable for both cosmetic and food applications .

    In skincare, ascorbyl palmitate is valued for its antioxidant properties, helping to protect the skin from free radicals, environmental stresses, and UV damage . It supports collagen synthesis, which may improve skin elasticity and reduce signs of aging , and it can also help brighten skin tone and diminish the appearance of dark spots and hyperpigmentation . Compared to pure ascorbic acid, ascorbyl palmitate is less irritating and more stable, making it easier to formulate in cosmetic products. However, research suggests its penetration and conversion to active Vitamin C within the skin are less efficient than some other derivatives .

    In food applications, ascorbyl palmitate is used as an antioxidant to protect oils and fats from oxidative rancidity, extending shelf life . After ingestion, it is hydrolyzed into ascorbic acid and palmitic acid, both of which are safely absorbed . Regulatory agencies such as the FDA have affirmed its safety (GRAS) for use in foods .

    Overall, ascorbyl palmitate is recognized as a safe, effective, and versatile ingredient in cosmetics and foods, offering antioxidant benefits and enhanced stability compared to water-soluble Vitamin C.
