3-O-ethyl ascorbic acid is an ethered derivative of ascorbic acid,the most excellent
derivative of ascorbic acid so far. It is very stable in chemical structure, a real stable and
discolored derivative of ascorbic acid, but also it can enter into skin and be metabolized
by body as ascorbic acid. So its effect is better than pure ascorbic acid. 3-O-ethyl
ascorbic acid is a unique lipophilic and hydrophilic material, easily used in cosmetic
formulation. The most important is that 3-O-ethyl ascorbic acid can easily enter into
dermis and play biological effect, while pure ascorbic acid almost does not enter into
dermis. 3-O-ethyl ascorbic acid is an excellent choice for cosmetic chemists.
