3-O-Ethyl-L-Ascorbic Acid, or Ethyl Ascorbic Acid is a molecule produced
by modifying Ascorbic Acid, commonly known as Vitamin C. This
modification is done to increase the molecule’s stability and enhance
its transport through skin, as pure Vitamin C is easily degraded. In the
body, the modifying group is removed and Vitamin C is restored in its
natural form. Thus, Ethyl Ascorbic Acid retains the benefits of Vitamin
C, such as antioxidant activity. Furthermore, it is even more potent in
reducing skin darkening after UV exposure. It even has some additional
effects, not observed in pure Ascorbic Acid, such as promoting nerve
cell growth or reducing chemotherapy damage. Finally, the slower release
also ensures that no toxic effects are observed when using this Vitamin
C derivative.
3-O-Ethyl-L-Ascorbic Acid
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.
