1.外觀為白色結(jié)晶粉末。2.維生素C乙基醚是一種親油的水溶性維生素C衍生物。其在配方中能夠極為方便的使用,容易穿透角質(zhì)層進(jìn)入皮革層,進(jìn)入皮膚后容易被生物酶分解而發(fā)揮維C的作用,從而提高其生物利用度,而普通的維生素C則很難被皮膚吸收,生物利用度很低。3.維生素C乙基醚相對普通的維生素C顯示出極高的穩(wěn)定性。4.維生素C乙基醚通過阻礙酪氨酸酶的Cu2+活性,阻斷***;防止日光引起的皮膚炎癥;改善皮膚色澤,促進(jìn)膠原蛋白產(chǎn)生,增加皮膚彈性。5.可用于凝膠、精華素、乳液、膏霜等美白淡斑、**老及其它護(hù)膚品。添加量:小于2%。</p><p

style="text-indent:25px">VC乙基醚，也叫維生素C乙基醚，它是采用擁有企業(yè)標(biāo)準(zhǔn)的生產(chǎn)工藝(一步合成法)合成的高純度維C衍生物，與維生素C（VC）有著本質(zhì)上的區(qū)別。維生素C（VC）以其淡斑美白作用以及高安全性得到認(rèn)可，但其本身極易被氧化，不易被皮膚真正吸收，皮膚利用度低。相對維C而言，VC乙基醚很容易穿透角質(zhì)層進(jìn)入層，進(jìn)入皮膚后被生物酶分解轉(zhuǎn)化為VC和H2O,從而發(fā)揮VC的作用，提高VC的利用度，從而起到更好的淡斑美白功效。阻礙酪氨酸酶活性，阻礙***，還原黑色素為無色，淡斑美白肌膚。VC乙基醚進(jìn)入層后直接參與膠原蛋白的合成修復(fù)皮膚細(xì)胞活性，使膠原蛋白增加，從而使皮膚變得充盈富有彈性，使肌膚細(xì)膩光滑。維生素C乙基醚分子量：204，分子式：C8H12O6。什么是維生素C乙基醚</p><p

1、維生素C乙基醚具有比較好的抗氧化能力，比VE的抗氧化能力強(qiáng)，可以說是自由基的收割機(jī)。 2、外用較高濃度的維生素C乙基醚可以防護(hù)光老化。 3、可以修復(fù)UVB帶來的損傷，協(xié)助防曬劑防護(hù)紫外線。 4、提高防曬霜的防護(hù)時間，所以很多防曬霜里都含有維生素C乙基醚。 5、VC還是膠原蛋白的調(diào)節(jié)因子，控制細(xì)胞間膠狀物質(zhì)的形成比如膠原蛋白。 6、還可以加強(qiáng)皮膚的免疫系統(tǒng)。 7、維生素C乙基醚可以滲透到皮膚底層，促進(jìn)曬傷或傷口的愈合。 8、近期的研究發(fā)現(xiàn)維生素C乙基醚具有***癥的作用。 9、也經(jīng)常出現(xiàn)在**老的產(chǎn)品中。
