Description

Ascorbyl Palmitate USP

Ascorbyl Palmitate USP is a high-purity, fat-soluble ester of Ascorbic Acid used in pharmaceutical, nutraceutical, food, and cosmetic formulations for its antioxidant properties. Compliant with United States Pharmacopeia (USP) standards, it combines the antioxidant activity of Vitamin C with enhanced lipid solubility, making it suitable for protecting oils, fats, and lipid-based formulations from oxidative degradation.
Ascorbyl Palmitate is chemically designated as L-Ascorbic Acid 6-Palmitate. It appears as a white to pale yellow crystalline powder that is practically insoluble in water and soluble in oils and organic solvents. Its lipophilic nature allows effective incorporation into emulsions, creams, capsules, and fat-containing dosage forms.
In pharmaceutical and related applications, Ascorbyl Palmitate USP is used in:
• Antioxidant stabilization of lipid-based drug products
• Oral supplements and multivitamin formulations
• Softgel capsules and oil-filled dosage forms
• Cosmetic and dermatological products requiring oxidative protection
• Food and medical nutrition products as an antioxidant preservative
• Combination formulations with Tocopherols and other antioxidants
Ascorbyl Palmitate USP functions by scavenging free radicals and inhibiting lipid peroxidation, thereby extending shelf life and preserving the integrity of active ingredients. In vivo, it can be hydrolyzed to release Ascorbic Acid, contributing additional antioxidant support.
