Abstract

AbstractAn exploratory study of the aqueous system of dimethyldodecyl amine oxide (DDAO) revealed it to be an interesting and instructive surfactant system showing the unusual occurrence of at least 5 stable phases at room temperature舒crystal (100‐about 80% DDAO), neat (about 80–70%), viscous isotropic (70–65%), middle (65–35%) and fluid isotropic or nigre (35–0%) in order of decreasing DDAO content. In many respects the system resembles anionic detergent systems such as that of sodium palmitate, in which, however, viscous isotropic is not observed. The maximum temperatures of existence for crystal, neat and middle are, respectively, 116, 145 and 110C. Neat phase is soft and anisotropic, viscous isotropic is somewhat brittle and isotropic, middle is plastic and anisotropic. The mesomorphic phases are particularly well shown microscopically in 舠dried‐down舡 samples under circular cover glasses. Middle and neat textures under the microscope are typical. At least four crystalline phases were recognized at various degrees of hydration.
