style="text-indent:25px">針對維生素C的市場應(yīng)用局限性，**對其進(jìn)行改良，使其充分發(fā)揮作用，目前zui常用的有兩種方法，一是把維生素C制成酯溶性的化妝品，這樣既穩(wěn)定了維生素C的還原力，而且還可以利用脂性物質(zhì)易深入皮膚的特點(diǎn)，使其順利地進(jìn)入皮膚。二是把維生素c制作成磷酸鎂鹽，因?yàn)榱姿徭V鹽經(jīng)皮膚吸收后，全被皮膚里的磷酸鹽分解酶所分解，從而發(fā)揮其作用。維生素C乙基醚（VC乙基醚）是一種親油親水的兩性維生素C衍生物，不僅保留了維生素C的氧化還原作用而且非常穩(wěn)定，是不變色的維生物C衍生物，而且它是親油親水兩性物質(zhì)，這不僅使其在配方中能夠極為方便的使用，更加使其容易穿透角質(zhì)層進(jìn)入真皮層，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。常州通用乙基VC

style="text-indent:25px">維生素C乙基醚說的是具有美白淡斑組合物及美白淡斑護(hù)膚品，根據(jù)所描述的美白淡斑組合物分由VC乙基醚、熊果苷、白芷提取物、煙酰胺、甘草酸二鉀、野菊維素組成。可以通過有效阻礙或阻止皮膚黑色素的生成、轉(zhuǎn)移，可以快速、有效地達(dá)到美白效果；能夠有效地解決美白活性成分易分解、易氧化、易變色等問題，降低了光線、熱對功效成分的影響，使其活性降低的問題；使用維生素C乙基醚所述的美白淡斑組合物及美白淡斑護(hù)膚品沒有其他作用，安全性好，能達(dá)到長久美白淡斑作用。</p><p style="text-indent:25px">維生素C乙基醚促進(jìn)膠原蛋白的合成。在膠原蛋白合成的程中，維生素C乙基醚的還原性可以刺激合成膠原蛋白過程中需要的酶。膠原蛋白可以增加皮膚的韌性，使皮膚更容易適應(yīng)環(huán)境，不容易因?yàn)楸砬橹惖囊蛩禺a(chǎn)生皺紋。所謂”剛強(qiáng)易折“，皮膚失去韌性發(fā)脆，就呈現(xiàn)剛性，容易受傷，而膠原蛋白可以避免這種情況。而且從視覺上，膠原蛋白可以令皮膚看上去飽滿。膠原蛋白可以提高皮膚含水量，使皮膚視覺上更白更通透。由于膠原蛋白主要依賴于體內(nèi)合成（至于比較偏門不被主流接受的“外敷膠原蛋白可以痕量吸收“這種理論，這里就不討論了），就需要皮膚中維生素C乙基醚含量足夠，來保證皮膚中膠原蛋白的合成過程。將維生素C乙基醚濕品送入干燥器進(jìn)行干燥,在去除乙酯后得到維生素C乙基醚干品。</p><div

style="text-indent:25px">從已知黑色素生成阻礙劑的作用機(jī)制來看可以分為兩類：1、對黑色素細(xì)胞的細(xì)胞毒性，阻礙黑色素的生成；2.阻礙黑色素細(xì)胞內(nèi)黑色素的生成。目前我國市場上還沒有一種公認(rèn)的安全有效的美白淡斑功能添加劑。大部分的美白淡斑護(hù)膚品的美白效果短暫，不明顯且見效慢，而有些淡斑產(chǎn)品為了增強(qiáng)和加快美白淡斑或淡斑效果，加入大劑量的氫醌或氨基**等有害物質(zhì)，致使部分消費(fèi)者出現(xiàn)嚴(yán)重過敏或不可逆汞斑（汞中毒）等毀容事件。因此對安全、有效的美白淡斑產(chǎn)品的研究一直是美容化妝行業(yè)重點(diǎn)關(guān)注的課題。維生素C乙基醚克服上述不足，提供一種含有VC乙基醚的美白淡斑組合物，以及含有該美白淡斑組合物的護(hù)膚品，能有效解決了現(xiàn)有美白產(chǎn)品美白效果短暫，不明顯且見效慢的問題，同時(shí)使用沒有其他作用，安全性好，能達(dá)到長久美白淡斑作用。維生素C乙基醚比VE的抗氧化能力強(qiáng)，可以說是自由基的收割機(jī)。浙江專業(yè)生產(chǎn)乙基VC

style="text-indent:25px">維生素C乙基醚進(jìn)入皮革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。阻礙酪氨酸酶活性，阻礙***，還原黑色素為無色，高效美白肌膚。在化妝品中有比較好的抗氧化效果，確保VC的利用度，相對VC而言，VC乙基醚非常穩(wěn)定，且不變色。真正達(dá)到美白淡斑的效果。具有親油和親水結(jié)構(gòu)，易于皮膚吸收，可直達(dá)皮革層.有效抑菌***作用，**光所引起的炎癥。穩(wěn)定性好，耐光、耐熱、耐酸、耐堿、耐鹽和空氣氧化維生素C以及其衍生物阻礙酪氨酸酶的效果.常州通用乙基VC
