Description

L-Ascorbyl 2,6-Dipalmitate is a lipid-soluble derivative of ascorbic acid (Vitamin C), specifically engineered for enhanced stability and compatibility in lipid-based systems. This compound matters as a highly effective fat-soluble antioxidant, providing superior protection against oxidative rancidity in sensitive formulations. It is primarily needed by manufacturers in the food, cosmetic, and nutraceutical industries seeking to stabilize oils, fats, and emulsions while delivering the benefits of Vitamin C.

Application

• As a primary antioxidant in edible oils, fats, and fat-containing food products to extend shelf life.
• As a stabilizing agent in cosmetic and personal care formulations, particularly in creams, lotions, and serums to protect active ingredients.
• In nutraceutical and dietary supplement manufacturing for oil-based softgel capsules and liquid formulations.
• As an additive in animal feed to provide antioxidant protection and Vitamin C activity.
• For the stabilization of pharmaceutical ointments and topical preparations.
• In industrial applications involving lubricants or polymers where antioxidant properties are required.
