Ethyl Ascorbic Acid is an excellent skin whitening agent,it inhibits the activity of Tyrosinase by acting on Cu2+ and it prevents the synthesis of melanin.It is an etherfied derivative of ascorbic acid,one of the most stable derivates of ascorbic acid.It's also showing a very good stability in all kinds of cosmetic formulations.
Ethyl Ascorbic Acid penetrates into skin where it is metabolized to ascorbic acid. Due to this process its efficacy is more pronounced than the one of pure ascorbic acid. Nonirritating to skin and eyes.

Description:
Vitamin C is a very useful vitamin C derivative. It is not only very stable in terms of chemical substances and is a non-discoloring vitamin C derivative, but also a hydrophilic and lipophilic substance, which greatly expands its applicable chemical book scope, especially in daily chemical applications. 3-O-ethyl ascorbic acid ether can easily pass through the stratum corneum into the dermis. After entering the body, it is very easy for the biological enzymes in the body to decompose and exert the biological effects of vitamin C.
Structural characteristics:
3-O-ethyl ascorbic acid ether is also called vitamin C . Vitamin C cannot be directly absorbed by the skin due to its 4 hydroxyl groups in its structure, and is easily oxidized and discolored, so its use as a whitening agent in cosmetics is limited. Vitamin C prepared by Chemicalbook after alkylation of the 3-hydroxyl group is a vitamin C derivative that does not change color and does not affect its biological activity, thus filling the gap in similar products on the market. Studies have shown that vitamin C ethyl is easily decomposed by enzymes after entering the skin and exerts the effect of vitamin C.
Use:
Vitamin C (VC ) is a lipophilic and hydrophilic amphoteric vitamin C derivative. It not only retains the redox effect of vitamin C but is also very stable. It is a non-discoloring vitamin C derivative and it is a lipophilic and hydrophilic amphoteric substance. This not only makes it extremely convenient to use in formulas, but also makes it easier to penetrate the stratum corneum and enter the dermis. After entering the skin, it is easily decomposed by biological enzymes to play the role of vitamin C, thereby improving its bioavailability.
Application:
1. Inhibit the activity of tyrosinase by acting on Cu2+, blocking the formation of melanin.
2. Very effective whitening and freckle removal (when added at 2%).
3. Anti-inflammatory caused by sunlight, with strong antibacterial and anti-inflammatory effects.
4. Improve dull skin and give skin elasticity.
5. Repair skin cell activity and promote collagen production.
