Description

6-(Oleoyloxy)-L-Ascorbic Acid is a lipophilic derivative of ascorbic acid (Vitamin C), formed by esterification with oleic acid. This chemical modification significantly enhances its stability and lipid solubility, making it a powerful oil-soluble antioxidant. It is primarily sought after by manufacturers in the cosmetics, personal care, and nutraceutical industries for its ability to protect formulations from oxidative degradation and deliver vitamin C benefits in oil-based systems.

Application

• Cosmetic & Skincare Formulations: As a key active ingredient in anti-aging serums, creams, and lotions for its antioxidant and skin-brightening properties.
• Hair Care Products: Used in oils and treatments to protect hair from environmental oxidative stress and improve scalp health.
• Nutraceutical & Functional Food Oils: Incorporated into edible oils and softgel supplements to prevent rancidity and enhance nutritional value.
• Pharmaceutical Topicals: Employed in ointments and transdermal delivery systems where oil solubility is required.
• Lipophilic Antioxidant for Industrial Oils: Protects sensitive oils and lipid-based ingredients in various industrial applications from oxidation.
• Research & Development: Serves as a biochemical reagent in studies related to lipid peroxidation and antioxidant mechanisms.
