[ Description ]
Ethyl Ascorbic Acid (also known as 3-O-Ethyl-L-Ascorbic Acid or VC Ethyl Ether) is a derivative of vitamin C designed to have greater stability than pure ascorbic acid. It retains antioxidant and skin-brightening properties. It is more resistant to degradation by light, air, and heat than L-ascorbic acid, making it highly suitable for cosmetic formulations.

[ Source and Characteristics ]
[ source: ] Chemically derived from L-ascorbic acid by ethylation (adding an ethyl group at the 3-O position).
[ appearance: ] White to off-white crystalline powder.
[ CAS: ] 86404-04-8
[ Molecular Formula: ] C₈H₁₂O₆

[ Main Components ]
Ethyl Ascorbic Acid is a single defined compound. The main component is 3-O-Ethyl-L-ascorbic Acid (also called VC Ethyl Ether).

[ Applications ]
1. Used in cosmetic formulations such as serums, creams, and lotions for skin brightening by inhibiting melanin production.
2. Acts as an antioxidant, protecting the skin from free radicals and oxidative stress caused by UV exposure and pollution.
3. Helps reduce the appearance of fine lines, improves firmness and elasticity by stimulating collagen synthesis.
4. Provides enhanced chemical stability compared to pure vitamin C, minimizing discoloration and preserving efficacy in formulations.
5. Often chosen for its gentler action with reduced irritation compared to pure L-ascorbic acid.
