    • PURPOSE: A polyoxyethylene(POE)-polyoxypropylene(POP) vitamin E is provided, which shows strengthened hydrophobicity of vitamin E(formula) by adding POP, and shows better surfactant effect by adding POE, then improves degradation-stabilizing degree of ethylene oxide(EO) in POE, so enhances oxidization-stability and makes each molecules cannot being penetrated into skin to show good skin safety and anti-oxidant effect. CONSTITUTION: A process for the preparation of polyoxyethylene-polyoxypropylene vitamin E comprises: pouring synthetic vitamin E(dl α-tocopherol) into a stainless steel autoclave; adding CH3ONa, and dehydarting for 30minutes while heating to 78deg.C(vacuum degree is 750mmHg); reacting with propylene oxide(PO) for 7hrs at 155-160deg.C to get liquid reactant(POP vitamin E); adding methoxy natrium, and pressure-pouring EO and reacting for 7hrs at 160-165deg.C while stirring; removing unreacted PO, EO and 1,4-dioxane, cooling to 50deg.C, and neutralizing alkali ingredient by adding citric acid; removing unreacted vitamin E with toluene, and refining with cephadex LH-50 column chromatography to get POE-POP vitamin E.
    • 目的:提供聚氧乙烯(POE) - 聚氧丙烯(POP)维生素E,通过加入POP显示出维生素E(配方)的疏水性增强,并通过加入POE显示更好的表面活性剂效果,提高环氧乙烷的降解稳定度( EO),因此提高了氧化稳定性,使每个分子不能渗入皮肤,表现出良好的皮肤安全性和抗氧化作用。 构成:制备聚氧乙烯 - 聚氧丙烯维生素E的方法包括:将合成维生素E(dlα-生育酚)倒入不锈钢高压釜中; 加入CH3ONa,脱水30分钟,同时加热至78℃(真空度为750mmHg); 与环氧丙烷(PO)反应,在155-160℃下反应7小时,得到液体反应物(POP维生素E); 加入甲氧基钠和加压注入EO,搅拌下在160-165℃下反应7小时; 除去未反应的PO,EO和1,4-二恶烷,冷却至50℃,加入柠檬酸中和碱成分; 用甲苯除去未反应的维生素E,并用cephadex LH-50柱色谱法精制得到POE-POP维生素E.
