Product Overview

3-O-Ethyl Ascorbic Acid (CAS 86404-04-8) is a highly stable, etherified derivative of Vitamin C (Ascorbic Acid). Unlike pure Vitamin C, which oxidizes rapidly, this Cosmetic Ingredient offers superior stability in aqueous and anhydrous formulations while maintaining excellent lipophilic and hydrophilic properties. It is easily absorbed by the skin and subsequently metabolized into natural Vitamin C, providing potent antioxidant protection, collagen synthesis promotion, and significant skin-brightening effects by inhibiting tyrosinase activity.
