CAS 4218-81-9: Ascorbyldipalmitate

Description: Ascorbyldipalmitate, with the CAS number 4218-81-9, is a fat-soluble derivative of ascorbic acid (vitamin C) formed by the esterification of ascorbic acid with palmitic acid. This compound is characterized by its antioxidant properties, which help protect against oxidative stress by neutralizing free radicals. Ascorbyldipalmitate is often used in cosmetic formulations and food products due to its ability to stabilize formulations and enhance the shelf life of products by preventing lipid oxidation. It is typically recognized for its emulsifying properties, allowing for improved texture and stability in creams and lotions. Additionally, ascorbyldipalmitate can contribute to skin health by promoting collagen synthesis and providing a source of vitamin C, albeit in a less bioavailable form compared to its free acid counterpart. Its solubility in oils rather than water makes it particularly useful in oil-based formulations. Overall, ascorbyldipalmitate serves as a multifunctional ingredient in various applications, combining the benefits of vitamin C with the stability of fatty acids.
