CAS No.: 86404-04-8
Product introduction:VC Ethyl Ether, also known as 3-O-Ethyl-L-ascorbic acid, is a stable, lipophilic derivative of vitamin C (L-ascorbic acid) developed to overcome the inherent instability and poor skin penetration of pure ascorbic acid . By introducing an ethyl group at the 3-position hydroxyl, this modification significantly enhances the molecule's resistance to oxidation while improving its ability to penetrate the stratum corneum. Once absorbed into the dermis, the compound is readily converted by biological enzymes to release active vitamin C, thereby exerting its antioxidant, collagen-synthesis-promoting, and skin-brightening effects
CAS No.:86404-04-8
VC Ethyl Ether is a white to off-white crystalline powder with the molecular formula C₈H₁₂O₆ and a molecular weight of approximately 204.18 g/mol . Its CAS number is 86404-04-8. The compound exhibits a melting point of approximately 114°C and a specific optical rotation of +45.0° to +49.0° (c=1, methanol) . It is freely soluble in water and various organic solvents, demonstrating good compatibility with both aqueous and oil-based formulation systems. For optimal stability, the product should be stored refrigerated (0-10°C) in a tightly sealed container, protected from light, as it is heat-sensitive . VC Ethyl Ether is typically available in research-grade and cosmetic-grade purities of ≥98% by HPLC.
