Description and Uses

3-O-Ethyl ascorbic acid ether, also called VC ethyl ether, is an ascorbic acid derivative. Ascorbic acid is a naturally occurring antioxidant and free radical scavenger, a reducing agent in the conversion process of biological enzymes, and has a preventive effect on some chronic diseases (cancer, diabetes and allergic skin diseases). From the molecular structure of ascorbic acid, it can be seen that compared to the 2-position enol hydroxyl group, the 3-position enol hydroxyl group has higher activity on electrophiles, and it is the product of 3-O-alkylation during O-alkylation modification. Mainly. 3-O-Ethyl ascorbate ether is a product of ascorbic acid-3-O-ethylation. It has a simple molecular structure and is easily absorbed by the skin. After entering the dermis through the stratum corneum of the skin, it is easily decomposed by the biological enzymes in the human body. The effect of ascorbic acid effectively solves the fat solubility problem of ascorbic acid, and is widely used in cosmetics as a whitening agent and antioxidant.

Vitamin C ethyl ether (VC ethyl ether) 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. It is a lipophilic and chemicalbook amphoteric substance, which not only makes it extremely convenient to use in the formula, but also makes it easy to penetrate the stratum corneum into the dermis. After entering the skin, it is easily decomposed by biological enzymes to play the role of vitamin C, thereby Improve its bioavailability.
