药用蔗糖脂肪酸酯(Sucrose Esters,简称SE)是国内最近研制成功的一类新的非离子型表面活性剂。这类化合物由蔗糖分子中一个或数个羟基与脂肪酸(硬脂酸、软脂酸、棕榈酸等)酯化而成。实际上,SE是单脂、双脂和三酯的混合物,改变它们的比例,其亲水性就发生变化。同时HLB值也可在1～16范围内变化。由于SE分子中同时存在性质相反的两亲性基团结构,且保持 Sucrose Esters (SE) is a new type of nonionic surfactant recently developed in China. Such compounds from sucrose molecule by one or several hydroxyl and fatty acids (stearic acid, palmitic acid, palmitic acid, etc.) from esterification. In fact, SE is a mixture of mono-, di-, and triesters whose hydrophilicity changes by changing their proportions. At the same time, the value of HLB can also be changed in the range of 1 ~ 16. Due to the simultaneous presence of amphiphilic groups in the SE molecule, they are maintained
