摘要：
Addition of alcohol with longer chain length (C6H13OH, C8H17OH, and C12H21OH) caused a reduction the cloud point of a commercial nonionic surfactant, Tesgitol (T-15-s-9). The formation of lamellar liquid crystal (LLC) was favored so that isotropic liquid (L(1))-LLC two-phase region became wider with increasing temperature at an appropriate weight ratio of surfactant to alcohol. The isotropic liquid phase/liquid two phase transformation was replaced by a two-phase transformation to isotropic liquid/lamellar liquid crystal at the cloud point for the system without alcohol.
