特性及用途：
白色結晶粉末，維生素C乙基醚是迄今為止較好的維生素C衍生物，它不僅在化學性能上非常穩(wěn)定，是真正意義上的不變色的維生素C衍生物，而且它進入皮膚后容易被生物酶分解而支持其維生素C的作用。維生素C乙基醚是親油親水物質(zhì)，這種性質(zhì)不僅使得其在配方中使用極其方便，更重要的是使其更容易穿透角質(zhì)層進入真皮層，使其抗氧化功能比其它維生素C衍生物強，而且美白作用也比維生素C及其衍生物效果好。它的美白作用一方面是通過抑制酪氨酸酶的活性，阻斷黑色素的產(chǎn)生；另一方面它還能將氧化型黑色素直接還原成淺色，充分發(fā)揮維生素C的生物學作用。而純的維生素C則很難被吸收進入皮膚。
1、 通過作用于酪氨酸酶的Cu2+抑制其活性，阻斷黑色素形成，還原黑色素為無色，高效祛斑美白肌膚；改善皮膚暗淡無光澤，賦予皮膚彈性；
2、 抗日光引起的炎癥，有較強的抗菌消炎作用；
3、 修復皮膚細胞，促進膠原蛋白產(chǎn)生。
因此在美白祛斑產(chǎn)品，抗衰老產(chǎn)品，水劑，凝膠，精華素，乳液，護膚霜等化妝品中得到應用。
建議用量：最好在PH值為3.0-6.0條件下使用，可以達到最佳效果，使用量：0.5-3%。
包裝貯存：1kg/袋，25 kg/桶。密封保存，有效期兩年。

Product description
3-O-Ethyl Ascorbic Ether (VCE) is etherified Vitamin C. It is an effective whitening agent and anti-oxidant that is metabolized by the human body in the same manner as regular vitamin C. It has also solved the structural instability of vitamin C and soluble in water as well as oil, making it optimal for use in cosmetics. Furthermore, VCE has anti-inflammatory effect. It is a multi-functional ingredient.
Effectiveness
1. Whitening Effect
Clinical tests conducted on human skin have proved that a 2% cosmetic formulation of EVC is effective for bleaching and brightening skin. It brightens and tones sun-damaged and dull-looking skin with dark spots.
2. Anti-Oxidant Effect
EVC is an antioxidant with a powerful reduction capability that dissolves both in water and oil. It reduces fat peroxide generated with cosmetics, prevents deterioration and is metabolized inside the human body just like regular vitamin C.
3. Formation and Synthesis of Collagen
EVC reacts to the formation and synthesis of skin cells and collagen in proportion to their consumption. The level of activation is about the same as ascorbic acid and ester phosphate. EVC restores the activities of collagen including its formation and synthesis. Also, it reduces the copper ion of tyrosinase to diminish its activation and thus prevent the formation of dark spots.
4. Anti-Inflammatory Effect
EVC works as a powerful anti-inflammatory when applied to the surface of skin. It suppresses the development of serotonin edema.
5. Delivery of Vitamin C to the dermis
EVC is not only stable but also soluble in water aswellas oil, enabling it to beabsorbedby the skin into the dermis.
