Description

L-Ascorbic Acid Phosphate Magnesium Salt is a stable, water-soluble derivative of Vitamin C, designed to overcome the inherent instability of ascorbic acid. This compound is valued for its ability to deliver the antioxidant and collagen-synthesizing benefits of Vitamin C in a more bioavailable and shelf-stable form. It is a critical ingredient for manufacturers in the cosmetic, nutraceutical, and pharmaceutical industries seeking effective and reliable active ingredients.

Application

• Cosmetic & Skincare Formulations: As a stabilized Vitamin C source in anti-aging serums, creams, and lotions for skin brightening, antioxidant protection, and collagen production.
• Nutraceutical & Dietary Supplements: Used in tablet, capsule, and powder formulations to provide a non-acidic, bioavailable source of Vitamin C.
• Pharmaceutical Intermediates: Serves as a key starting material or active component in specialized drug delivery systems and medicinal products.
• Functional Food & Beverage Fortification: Incorporated into health drinks and foods where a neutral pH and high stability of Vitamin C are required.
• Biochemical Research: Utilized in cell culture media and as a reagent in studies involving oxidative stress and collagen synthesis.
• Animal Feed Additives: Employed as a vitamin supplement in premium feed to support animal health and immunity.
