Description

6-o-Acetylascorbic Acid is a chemically modified derivative of ascorbic acid (Vitamin C), designed to enhance stability and functionality. This compound is valued for its role as a versatile intermediate and active ingredient, offering improved lipophilicity and resistance to oxidation compared to its parent molecule. It is primarily sought after by manufacturers in the cosmetic, pharmaceutical, and nutraceutical industries for its skin-brightening, antioxidant, and stabilizing properties.

Application

• Cosmetic & Skincare Formulations: Used as a stable, oil-soluble source of Vitamin C in serums, creams, and lotions for skin brightening, antioxidant protection, and collagen synthesis promotion.
• Pharmaceutical Intermediates: Serves as a key synthetic precursor in the production of more complex pharmaceutical compounds and prodrugs.
• Nutraceutical & Food Fortification: Employed as a stabilized form of Vitamin C in dietary supplements and functional food products where enhanced shelf-life is required.
• Antioxidant Stabilizer: Functions as an antioxidant additive in various sensitive chemical mixtures and formulations to prevent oxidative degradation.
• Research & Development: Utilized in biochemical research and as a standard in analytical laboratories for method development and quality control.
