Food additives

Cosmate®EVC,Ethyl Ascorbic Acid is an effective whitening agent and anti-oxidant that is metabolized by the human body in same manner as regular vitamin C. Vitamin C is a water-soluble antioxidant but cannot be dissolved in any other organic solvents. Because it is structurally unstable, Vitamin C has limited applications. Ethyl Ascorbic Acid dissolves in a variety of solvents including water, oil and alcohol and therefore can be mixed with any prescribed solvents. It can be applied to suspension, cream, lotion, serum. water-oil compound lotion, lotion with solid materials, masks, puffs and sheets.

Description:
3-O-Ethyl-L-ascorbic acid inhibits tyrosinase activity, inhibits the formation of melanin, restores melanin to colorless, effectively removes freckles and whitens, improves dull skin, and endorses skin elasticity. It has an excellent antioxidant effect in cosmetics and ensures the utilization of vitamin C. Compared to the vitamin C prototype, it is very stable and does not discolor. It has a strong antibacterial and anti-inflammatory effect and fights inflammation caused by sunlight. It enters the dermis, directly participates in the synthesis of collagen, repairs the activity of skin cells, increases collagen, and makes the skin full, elastic, delicate and smooth. It has a lipophilic hydrophilic structure, which is easily absorbed by the skin and can reach the dermis directly. It demonstrates good stability against light exposure as well as resistance to heat, acid-alkali conditions, salt corrosion, and air oxidation.

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.
