3-O-Ethyl-L-ascorbic acid(or VCE for short )
Product characteristics:
1. VC ethyl ether directly participates in collagen synthesis to repair skin cell activity after entering dermal layer, so that collagen is increased, thus making skin full and elastic, making skin delicate and smooth.
2. It inhibits tyrosinase activity, inhibits melanin formation, reduces melanin to colorless, thus effectively whitening skin.
3. It has excellent antioxidant effect in cosmetics, which ensures the utilization of VC. Compared with VC, VC ethyl ether is very stable and does not change color, which really achieves the effect of whitening and removing spots.
4. It has lipophilic and hydrophilic structure, which is easy to be absorbed by skin and can reach the dermis layer directly.
5. It has strong antibacterial and anti-inflammatory effects and can resist inflammation caused by sunlight.
6. It has good stability, light resistance, heat resistance, acid resistance, alkali resistance, salt resistance and air oxidation resistance.
7. The inhibitory effect of vitamin C and its derivatives on tyrosinase.
8. It can inhibit the Cu2+ activity of tyrosinase, block the formation of melanin, prevent skin inflammation caused by sunlight, improve skin color, promote the production of collagen and increase skin elasticity.
Product application:
It is a raw material for whitening and freckle removing cosmetics, which has strong antibacterial and anti-inflammatory effects. It is widely used in whitening, freckle removing, anti-aging and other skin care products such as gel, essence, lotion and cream. The normal addition amount is 0.5%-2.0%. It is suggested that 0.2% sodium citrate should be added to the formula, and the pH value of the formula should be controlled in the range of 4.0-6.0, so as to achieve the best effect.
