Comparing the phase diagrams of three binary soap systems KC18/ethylene glycol, KC18/buthylene glycol, and KC18/glycerol, we found systematic alterations in the types of phase diagrams that depend on the chemical structure of the solvents. The following mesophases were observed: lamellar phases, hexagonal phases isotropic phases, and gel phases. Differences in number, position, extension, and the sequence of the occurring mesophases were found as a function of concentration of the mixtures and temperature. We came to the conclusion that the influence which the solution medium exerts on the formation of structures in the binary systems is very distinct and pronounced.
