Abstract

The phase diagrams of fatty alcohol sulphates (FAS)/ fatty alcohol ether sulphates (FAES)/water and mixed FAS:FAES (1:1)/propylene glycol/water were constructed at room temperature. Another phase diagram of mixed FAES/FAS/soap (4.5:4.5:1.0)/propylene glycol/water were established at 60 °C. Birefringence was observed under cross-polarized light and their phase changes examined under a polarized microscope. The liquid crystalline region for FAES and FAS occurred only in a small region. The optical patterns of lamellar liquid crystal observed were oily streaks and a typical fine cross-striated structure.
