Description

2-o-Octadecylascorbic Acid is a lipophilic derivative of ascorbic acid (Vitamin C) where an octadecyl (stearyl) chain is attached to the 2-position oxygen, significantly altering its solubility profile. This structural modification is crucial for enhancing stability and facilitating incorporation into lipid-based systems where traditional ascorbic acid is ineffective. It is primarily sought after by formulators in the cosmetics, personal care, and nutraceutical industries for its antioxidant properties and skin benefits.

Application

• Cosmetic & Skincare Actives: As a stabilized, oil-soluble antioxidant in anti-aging serums, creams, and lotions to protect skin from oxidative stress.
• Personal Care Formulations: Used in sun care products, color cosmetics, and hair care treatments where lipid compatibility is required.
• Nutraceutical & Functional Food Ingredients: Potential use in fat-soluble vitamin C supplements or fortified lipid-based food products.
• Pharmaceutical Intermediates: Serves as a key synthetic intermediate for more complex lipophilic ascorbic acid derivatives with targeted bioactivity.
• Industrial Antioxidants: Application in stabilizing oils, fats, and polymer matrices against oxidation due to its lipid-soluble nature.
• Research & Development: Used in biochemical research to study the effects of lipophilic antioxidants in cellular lipid membranes.
