3-O-Ethyl-L-ascorbic acid Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
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.
Verwenden
3-O-Ethyl-L-ascorbic Acid could be a useful stabilizing agent for a para-hydroxyacetophenone solution. It could be a useful stabilizing agent for a para-?hydroxyacetophenone solution.
Mechanism of action
VC ethyl ether penetrates the stratum corneum to reach the melanocytes in the basal layer, inhibits tyrosinase activity, inhibits the formation of melanin, and restores melanin to colorless, thereby effectively whitening the skin. And Chemicalbook and VC ethyl ether can directly participate in the synthesis of collagen and repair skin cell activity after entering the dermis, increasing collagen, so that the skin becomes full and elastic, making the skin delicate and smooth.
