The phase diagram of the ternary dodecyltetraethylene glycol tion at a fixed surfactant content. L al and L ah are birefrigent, (C 12 E 4 )/benzyl alcohol/water system with a surfactant concentra-and lamellar phases, L / a and L 3 , are optically isotropic, with tion of up to 0.2 M was determined. With an increase in the alcohol streaming birefrigence and located at, respectively, smaller concentration, the sequence of the phases was L al , L ah , L 3 /L ah ,

The influence of a small amount of cetylpyridinium chloride on the phase diagram of the diluted C 12 E 4 /benzyl alcohol/water system is studied. The presence of the ionic surfactant results in the stabilization of the vesicles in relation to the open bilayers. The bilayer structures are less sensit
