3-O-Ethyl-L-Ascorbic Acid/CAS:86404-04-8

3-O-Ethyl-L-Ascorbic Acid (EAA) is a novel, highly stable vitamin C derivative (CAS No. 86404-04-8), belonging to the high-end cosmetic active ingredient category. This product is a white to off-white crystalline powder with excellent antioxidant stability, water solubility, and skin penetration. It is one of the most widely used whitening, anti-aging, and skin-repairing ingredients in global skincare formulations.

Compared to traditional L-ascorbic acid (vitamin C), 3-O-Ethyl-L-Ascorbic Acid exhibits improved stability through structural modification, effectively reducing oxidative inactivation caused by changes in light, oxygen, and temperature, resulting in a longer activity retention time in skincare formulations. Furthermore, this ingredient can be converted into vitamin C within the skin, exerting vitamin C-related skincare benefits, thus attracting widespread attention from international cosmetic brands and raw material suppliers.
