Magnesium Ascorbyl Phosphate

Magnesium Ascorbyl Phosphate (CAS 114040-31-2 ), commonly abbreviated as MAP, is a water-soluble, stable derivative of Vitamin C used primarily in cosmetic and personal care formulations. Unlike pure ascorbic acid, it resists oxidative degradation, making it a reliable active ingredient for manufacturers seeking consistent performance across product shelf life. In skincare formulations, MAP is used as a brightening and antioxidant active in serums, moisturizers, and emulsions where standard Vitamin C would destabilize. Suncare and post-sun products incorporate it to support antioxidant protection alongside UV filters. In pharmaceutical topical preparations, it functions as a stabilized Vitamin C source. Food and nutraceutical manufacturers also use MAP as a Vitamin C fortification ingredient where stability under processing conditions is a sourcing priority for the industry. Magnesium Ascorbyl Phosphate is supplied as a white to off-white powder. It is available in cosmetic-grade and food-grade specifications, with purity levels typically at 95% or higher. Buyers should confirm grade compliance, particularly USP or FCC designation, when sourcing for pharmaceutical or food fortification end uses to ensure quality.
