Self-organization processes in mixed water solutions of zwitterionic surfactant – oleylamidopropyl betaine (OAPB) and anionic surfactant – sodium dodecylbenzolsulphonate (SDBS) were investigated in this work. It was established that in mixed solutions synergistic effects of reduced tension were observed. This is due electrostatic attraction between zwitterionic and anionic surfactants. By dynamic light scattering method it was found that at certain concentrations in the volume of mixed solutions of OAPB and SDBS the aggregates of several sizes coexist and network of micellar chain entanglements is present. Also, a correlation between structure transformations in micellar solution and viscosity changes was also established.
