3-O-ethyl-L-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-L-ascorbic acid is a unique lipophilic and hydrophilic
material, easily used in cosmetic formulation. The most important is
that 3-O-ethyl-L-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.
l-ascorbic acid (AA), commonly known as vitamin C, has been widely used
in topical formulations for many years as an antioxidant and anti-aging
ingredient. However, the physicochemical properties of AA are not
optimal for skin uptake and the molecule is also unstable, readily
undergoing oxidation on exposure to air. The compound
3-o-ethyl-l-ascorbic acid (EA) has been developed as a stable vitamin C
derivative and has been used in topical products.
