2-O-Ethyl Ascorbic Acid
What is 2-O-Ethyl Ascorbic Acid?
2-O-Ethyl Ascorbic Acid is a synthetic, water-soluble derivative of L-ascorbic acid, modified by attaching an ethyl group to enhance stability against oxidation, light, and heat compared to pure vitamin C. This chemical alteration allows it to remain effective in a broader pH range and various formulations. Commonly incorporated into serums, creams, and lotions within the antioxidant and skin conditioning categories of cosmetics, it functions by gradually releasing active ascorbic acid upon skin penetration. Its stability makes it suitable for daytime products without rapid degradation, supporting its role in formulations aimed at environmental protection and conditioning. Derived through esterification processes, it maintains the core structure of vitamin C while improving solubility and shelf-life in aqueous systems.
Benefits
