Product Introduction
3-O-Ethyl Ascorbicacid is a very useful vitamin C derivative. It is not only very stable chemically, it is a non-discoloring vitamin C derivative, and it is a lipophilic and hydrophilic amphoteric substance, which greatly expands its Scope of application, especially in daily chemicals. 3-O-ethyl ascorbic acid ether can easily enter the dermis through the stratum corneum. After it enters the body, it is easily decomposed by biological enzymes in the body to exert the biological effects of vitamin C.
3-O-Ethyl Ascorbicacid penetrates the stratum corneum directly to the melanocytes of the basal layer, inhibits tyrosinase activity, inhibits the formation of melanin, and reduces melanin to colorless, thereby effectively whitening the skin. Moreover, 3-O-Ethyl Ascorbicacid can enter the dermis and directly participate in the synthesis of collagen Chemicalbook protein to repair skin cell activity and increase collagen, thereby making the skin plump and elastic, making the skin delicate and smooth. 3-O-Ethyl Ascorbicacid may be a useful stabilizer for p-hydroxyacetophenone solutions.
3-O-Ethyl ascorbic acid ether (vitamin C ethyl ether) is a substance that is soluble in oil and water, which allows formulators to add it to the oil phase or water phase, or add it at high or low temperatures, making it easy to use. More importantly, this two-solubility makes it easier to penetrate the stratum corneum and enter the dermis to exert its biological effects, which is something other Chemicalbook vitamin C derivatives do not have. It can block the formation of melanin by inhibiting the activity of tyrosinase; it has whitening and freckle removal effects; it resists inflammation caused by sunlight and has strong antibacterial and anti-inflammatory effects; it also improves dull and dull skin, gives it luster, elasticity, and repairs Stimulates skin cell activity and promotes collagen production.

Product Function
1. Whitening effect: 3-O-Ethyl Ascorbicacid can inhibit the activity of tyrosinase in the skin, thereby preventing the formation of melanin and achieving whitening effects. At the same time, it can promote skin metabolism and help remove pigment spots that have formed.
2. Antioxidant effect: 3-O-Ethyl Ascorbicacid has strong antioxidant ability, which can scavenge free radicals and prevent skin from being damaged by ultraviolet rays and environmental pollution. Long-term use can improve the skin's luster and elasticity and delay skin aging.
3. Promote collagen synthesis: 3-O-Ethyl Ascorbicacid can also promote the synthesis of collagen in the skin, which is very important for maintaining the elasticity and firmness of the skin.
Product Application
3-O-Ethyl Ascorbicacid is widely used in whitening and anti-aging skin care products, such as lotion, cream, toner, mask, essence, etc. The recommended dosage in cosmetics is 0.5-3%.
