  • Applications

    Magnesium Ascorbyl Phosphate (MAP), CAS 113170-55-1, is a water-soluble derivative of ascorbic acid that acts primarily as an antioxidant in formulations. In cosmetics/personal care, it is used as a stable vitamin C derivative to protect components from oxidation and stabilize product textures, commonly found in creams, serums, and lotions. In pharmaceuticals, MAP is used as an antioxidant additive in certain drug formulations and health-care products to help stabilize active ingredients and extend shelf life. In industrial manufacturing, MAP serves as a stabilizer for plastics and coating systems, helping to reduce oxidative aging of resins, pigments, and coatings. In coatings and inks, MAP is employed to improve oxidative stability of formulation components and extend product lifetimes.
