3-O-Ethyl-L-ascorbic Acid CAS 86404-04-8

Introduction to the research course of 3-O-Ethyl-L-ascorbic acid:The invention discloses a separation and purification method for preparing 3-O-alkyl ascorbate ether from vitamin C by one-step method. The method comprises the following steps: reacting vitamin C, alkali and alkylating agent in a solvent to synthesize 3-O-alkyl ascorbic acid ether; After the reaction is finished, the reaction solvent is recovered, the residue is diluted with water.subjected to ion exchange on a strongly basic anion exchange resin column, and washed with water until the pH of the effluent is less than or equal to 8;Then, the effluent containing 3-O-alkyl ascorbate ether is combined with a dilute acid washing column, and finally the elution can be stopped when there is no 3-O-alkyl ascorbate ether in the effluent;

Main effects:

1, 3-O-Ethyl-L-ascorbic acid directly participates in the synthesis of collagen to repair the activity of skin cells after entering the dermis, which increases collagen, thus making the skin full and elastic, and making the skin delicate and smooth.

2, inhibit tyrosinase activity, inhibit the formation of melanin, reduce melanin to colorless, and effectively whiten skin.

3, It has excellent antioxidant effect in cosmetics to ensure the availability of VC. Compared with VC, VC ethyl ether is very stable and does not change color. Really achieve the effect of whitening and freckle removal.

4, It has lipophilic and hydrophilic structure, which is easy to be absorbed by the skin and can reach the dermis directly.

5, strong antibacterial and anti-inflammatory effects, anti-inflammation caused by anti-Japanese light.

6, good stability, light resistance, heat resistance, acid resistance, alkali resistance, salt resistance and air oxidation.

7, Inhibitory effect of vitamin C and its derivatives on tyrosinase

8, Furunke used 3-O-Ethyl-L-ascorbic acid to achieve the effect of whitening and freckle removal.

How does the whitening effect of 3-O-Ethyl-L-ascorbic acid work?

3-O-Ethyl-L-ascorbic acid (VC ethyl ether) is an oleophilic and hydrophilic amphoteric vitamin C derivative, which not only retains the redox effect of vitamin C, but also is very stable. It is an amphipathic vitamin C derivative with no discoloration, and it is an oleophilic and hydrophilic Chemicalbook, which not only makes it very convenient to use in the formula, but also makes it easy to penetrate the stratum corneum and enter the dermis, and it is easy to be decomposed by biological enzymes after entering the skin to play the role of vitamin C, thus improving its bioavailability.
[Application] Whitening and freckle removing products, anti-aging products, aqua, gel, essence, emulsion, skin cream, etc. [Recommended dosage] 0.1-2.0%, which is suitable to be used in whitening and freckle removing products, wrinkle removing and anti-aging products. [Operation suggestion] It is best to use it under the condition of PH3.0-6.0, and the whitening and freckle removing effect is the best.
