Property:
3-O-Ethyl-L-ascorbic acid is the best one of vitamin C derivatives by far, it is not only very stable, but also easily broken down by enzymes in the skin. 3-O-Ethyl-L-ascorbic acid is one amphiphilic substance, which makes it extremely easy to be used in the formulation. This amphiphilic makes it easier to penetrate the stratum corneum into the dermal layer, and play its biological effect.
Efficacy:  
By acting on the Cu2 + , inhibition of tyrosinase activity, blocking the formation of melanin;
Effective whitening and dispelling freckle effect;
Resistance inflammation caused by the sun light, there is a strong anti-bacterial anti-inflamm atory effect;
Promotes collagen synthesis, improves dull skin and gives skin elasticity.

Usage: skin lightening product, anti-aging product, liquid, gel, cream, lotion, skin cream, etc.; suggest the best used condition in the PH 3.0-6.0, the best skin lightening.

Vitamin C ethyl ether is a very useful vitamin C derivative. It is not only very chemically stable, it is a vitamin C derivative that does not change color, and it is a lipophilic hydrophilic amphoteric substance, which greatly expands him. The scope of application, especially in the application of daily chemistry. 3-O-ethyl ascorbate can easily enter the dermis through the stratum corneum. After entering the body, it is very easy to decompose the enzymes in the body to exert the biological effects of vitamin C.

VC ethyl ether, also known as vitamin C ethyl ether, is a high-purity vitamin C derivative synthesized by a national patented production process (one-step synthesis), which is essentially different from vitamin C (VC). Vitamin C (VC) is recognized for its high-efficiency freckle whitening effect and high safety, but it is easily oxidized, not easily absorbed by the skin, and has low skin utilization. Relative to the dimension C, VC ethyl ether easily penetrates the stratum corneum into the dermis layer, and is converted into VC and H2O by bio-enzyme decomposition after entering the skin, thereby exerting the role of VC and improving the utilization of VC, thereby playing a better role. The freckle whitening effect.


Main effects:

l. VC ethyl ether enters the dermis and directly participates in the synthesis of collagen to repair the skin cell activity, so that the collagen is increased, so that the skin becomes full and elastic, making the skin delicate and smooth.

2. inhibit tyrosinase activity, inhibit the formation of melanin, reduce melanin to colorless, high-efficiency whitening skin.

3. Excellent anti-oxidation effect in cosmetics, ensuring the utilization of VC. Compared with VC, VC ethyl ether is very stable and does not change color. Really achieve the effect of whitening and freckle.

4. with lipophilic and hydrophilic structure, easy to absorb the skin, can reach the dermis

5. strong antibacterial anti-inflammatory effect, anti-sunlight caused by inflammation.

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

8. vitamin C and its derivatives inhibit the effect of tyrosinase
