An influence of solubilisation on electrokinetic properties of colloidal solutions of cationic surfactants based on octadecylpropylendiamine and alkylamidopolyamine is investigated. As shown, the introduction of polyatomic spirits and hexane into water solutions of surfactants based on alkylamidopolyamine results in growth of the micelles’ zeta-potential, which is caused by change of existence area of steady colloidal systems. Efficiency of hydrotropic- substances’ action forms the series as follows: ethylene glycol???hexane >glycerine. Introduction of these compounds into diamine solutions exerts insignificant influence on electrokinetic characteristics of a system.
