Description

6-S-Hexadecyl-2-Methoxythioascorbic Acid is a specialized lipophilic derivative of ascorbic acid, engineered for enhanced stability and solubility in lipid-based systems. This compound matters for its potent antioxidant properties, which are crucial for protecting sensitive formulations from oxidative degradation. It is primarily needed by manufacturers in the cosmetics, nutraceutical, and specialty chemical industries seeking advanced stabilization solutions for high-value products.

Application

• Cosmetic & Skincare Formulations: Acts as a primary antioxidant and anti-aging agent in creams, serums, and lotions to prevent rancidity and protect skin from environmental stressors.
• Nutraceutical & Dietary Supplements: Used in oil-soluble supplement blends and softgel capsules for its enhanced bioavailability and stability compared to standard ascorbic acid.
• Pharmaceutical Intermediates: Serves as a key building block in the synthesis of more complex pharmaceutical agents requiring lipophilic antioxidant moieties.
• Food & Beverage Fortification: Employed as a stabilizer in fat-soluble vitamin premixes and functional food ingredients to extend shelf-life.
• Industrial Antioxidant: Protects polymers, lubricants, and other industrial materials from oxidative breakdown.
• Research & Development: Utilized in biochemical research to study lipid peroxidation and develop new antioxidant delivery systems.
