特性及用途：

白色结晶粉末，维生素C乙基醚是迄今为止较好的维生素C衍生物，它不仅在化学性能上非常稳定，是真正意义上的不变色的维生素C衍生物，而且它进入皮肤后容易被生物酶分解而支持其维生素C的作用。维生素C乙基醚是亲油亲水物质，这种性质不仅使得其在配方中使用极其方便，更重要的是使其更容易穿透角质层进入真皮层，使其抗氧化功能比其它维生素C衍生物强，而且美白作用也比维生素C及其衍生物效果好。它的美白作用一方面是通过抑制酪氨酸酶的活性，阻断黑色素的产生；另一方面它还能将氧化型黑色素直接还原成浅色，充分发挥维生素C的生物学作用。而纯的维生素C则很难被吸收进入皮肤。

1、 通过作用于酪氨酸酶的Cu²⁺抑制其活性，阻断黑色素形成，还原黑色素为无色，高效祛斑美白肌肤；改善皮肤暗淡无光泽，赋予皮肤弹性；

2、 抗日光引起的炎症，有较强的抗菌消炎作用；

3、 修复皮肤细胞，促进胶原蛋白产生。

因此在美白祛斑产品，抗衰老产品，水剂，凝胶，精华素，乳液，护肤霜等化妆品中得到应用。

建议用量：最好在PH值为3.0-6.0条件下使用，可以达到最佳效果，使用量：0.5-3%。

包装贮存：1kg/袋，25 kg/桶。密封保存，有效期两年。

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.
