  • Applications

    Magnesium ascorbate (CAS 15431-40-0) is a salt of ascorbic acid that serves as a source of ascorbate and magnesium in multiple applications. In cosmetics/personal care it is used as a stable vitamin C derivative and antioxidant to help protect formulations from oxidation and support product stability. In pharmaceuticals and dietary supplements it is commonly evaluated as a vitamin C source in finished dosage forms and nutraceuticals, contributing to formulation stability and pH balance. In food processing it can function as an antioxidant and nutrient fortificant, helping preserve quality during storage and processing. In industrial manufacturing and coatings/inks it may act as a stabilizer or reducing agent in certain formulations, potentially supporting polymer and resin systems that require antioxidant protection. Use is subject to local regulations and formulation limits.
