Abstract

Two non-ionic surfactants (Simulsol OL 50 and Simulsol 98) separately or as 1:1 mixtures, together with corn oil-undecylenic acid and water formed various phases. Phase equilibrium studies were made. In all phase equilibrium diagrams investigated, both at 20 and 37 degrees C, lamellar and hexagonal liquid crystalline and oily isotropic phases were found, besides the emulsion system. Emulsions were composed of mixed lamellar and hexagonal liquid crystalline phases which formed at low concentrations of surfactant and oil and correspondingly high water concentrations.

摘要

两种非离子表面活性剂（Simulsol OL 50和Simulsol 98）单独或按1:1混合，与玉米油 - 十一烯酸和水形成了不同的相。进行了相平衡研究。在所有研究的相平衡图中，无论是在20℃还是37℃，除了乳液体系外，还发现了层状、六方液晶和油性各向同性相。乳液由混合的层状和六方液晶相组成，这些相在低浓度的表面活性剂和油以及相应高浓度的水的情况下形成。
