Ethylated Ascorbic Acid
Ethylated Ascorbic Acid — a stabilized vitamin C derivative, also known as 3-O-ethyl ascorbic acid, in which an ethyl group is attached to ascorbic acid to improve stability while allowing conversion to active vitamin C. It is both water- and partly oil-compatible, making it versatile across formulations.
Key points
- Ethylated ascorbic acid (3-O-ethyl ascorbic acid) resists oxidation better than pure L-ascorbic acid.
- It is studied for antioxidant activity and support of a brighter, more even skin tone.
- Its structure allows relatively good skin penetration compared to some other derivatives.
- It is often used in modern serums seeking both stability and vitamin C benefits.
Frequently asked
What does the '3-O-ethyl' in ethylated ascorbic acid mean?
It refers to an ethyl group bonded at a specific position on the ascorbic acid molecule, which stabilizes it while still allowing conversion to active vitamin C in the skin.
Can ethylated ascorbic acid be used daily?
It is generally suitable for daily use and is well tolerated by many skin types, though introducing it gradually helps you gauge your skin's response.
