Vitamin C ethyl ether is on the 3-position hydroxyl structure of vitamin C, replaced by ethyl group, so as to protect vitamin C from oxidation and damage to activity, is a hydrophilic and lipophilic amphoteric vitamin C derivative, not only can be more convenient to use into the formula, and easy to penetrate the stratum corneum into the dermis, into the skin after being decomposed by biological enzymes to play the role of vitamin C.
Efficacy
1. Inhibit tyrosinase activity, inhibit the formation of melanin, reduce melanin to colorless, effectively remove freckle and whiten skin, improve skin dullness and dullness, and give skin elasticity.
2. It has excellent antioxidant effect in cosmetics to ensure the utilization of vitamin C, and compared with vitamin C prototypes, vitamin C ethyl ether is very stable and not easy to discolor.
3. Strong antibacterial and anti-inflammatory effect, anti-inflammatory inflammation caused by sunlight.
After entering the dermis, 4-dimensional C ethyl ether directly participates in the synthesis of collagen to repair the activity of skin cells, so that collagen increases, so that the skin becomes plump and elastic, and the skin is delicate and smooth.
5. It has a lipophilic and hydrophilic structure, which is easy to absorb by the skin and can reach the dermis directly.
6. Good stability, light, heat, acid, alkali, salt and air oxidation.
Stability test comparison
BeriCos® VCE has a good stability.
Test Subject: 10% aqueous VCE solution
Test content: Placed at room temperature/window sill light/45°C oven
Test duration: 2023.5.16~2023.9.5(>3 months)
Test results: As shown in the figure below, the 10% VCE aqueous solution does not require any protective agent or pH adjustment, and does not have any color change under high temperature and light conditions; In contrast, the aqueous solution of 10% prototype VC showed a significant color change.
