摘要: 对人豆卵磷脂进行羟氯化改性,以此为表面活性剂,醇为助表面活性剂。采用三相图形式和电导率来进行跟踪检测。对室温下改性卵磷脂各体统中微乳区域的形成以及微乳液理化性质随系统中各组分的变化情况进行了研究。结果发现醇中碳的数目为3时,微乳区域最大;电导率与微乳化有关。改性后的大豆卵磷脂比改性前的效果有明显的改善,羟氯化改性卵磷脂为不错的制备药物载体。

Abstract: The formation of microemulsion phase for systems containing modified soybean lecithin and the effect of formulationvariables on the physical-chemistry characterization of micioemuision were studied. Soybean lecithin was modified byhydroxychloride in NaClO. Then it was used as surfactant and several short chain alcohols and investigated as cosurfactant.Investigation of the phase and conductance for the microemulsion showed that if C≈3,it could hold the biggest microemulsion.And conductivity would change with water. Modified soybean lecithin was found more effective than lecithin. It was used betterin drug delivery system. And it could be used in reduced amount in cholesterin.

Key words: soybean lecithin, modification, microemulsion, cosurfactant, pseudo-ternary diagrams, conductivity
