在给定的水/油体系中，当两种表面活性剂混合以调整混合物的亲水-亲脂平衡（HLB）时，由微乳液、水和油相组成的三相体在矩形相图中被扭曲。这种畸变主要是由于每种表面活性剂在三个共存相中的溶解度不同。考虑表面活性剂在微乳相中微观水/油界面处的混合比例，采用HLB平面法了解微乳相中微观水/油界面的整个三相行为。利用该方法，计算了特定三相三角形在组合物空间中的位置。我们改进了HLB平面方法，使其适用于非离子表面活性剂-小两亲体体系的三相行为，其中小两亲体在水和油中都具有相当的可溶性。该方法可以准确地确定相图中的HLB平面（三相tie三角形）。聚氧乙基的三相行为…
A three-phase body consisting of microemulsion, water, and oil phases is distorted in a rectangular phase diagram, when two surfactants are mixed to adjust the hydrophile−lipophile balance (HLB) of the mixture in a given water/oil system. This distortion is mainly attributed to the difference in solubilities of each surfactant in three coexisting phases. The HLB plane method is used to understand the whole three-phase behavior considering the mixing fraction of surfactant at the microscopic water/oil interface inside the microemulsion phase. With this method, the position of a particular three-phase tie triangle is calculated in the space of compositions. We have modified the HLB plane method to be applicable for the three-phase behavior of nonionic surfactant−small amphiphile systems, in which small amphiphiles are considerably soluble both in water and oil. The method can be used to accurately determine the HLB plane (three-phase tie triangle) in phase diagrams. The three-phase behavior in polyoxyethyle...
