• The ability to aggregate and the solubilizing activity were estimated for typical hydrotropic compounds and their structural analogues, i.e. salts of acetic and aromatic acids as well as non-electrolytes such as thymol and N-methylglucamine. The effect of these additives on aggregation characteristics, viscosity and solubilizing properties of typical surfactants was studied together with the self-aggregation in individual additive solutions. A decrease of the surface tension of aqueous surfactant solutions was observed in the presence of thymol, whereas conductivity has unchanged. Viscosity in the cetyltrimethylammonium bromide (CTAB)–thymol system increases by more than two orders of magnitude as compared to individual CTAB micelles. A maximum increase in the solubilizing ability of the CTAB solutions was observed in the presence of N-methylglucamine. [Display omitted] •A marked effect of cation nature on the solution behavior of salts of acetic acid occurs.•Viscosity of CTAB–thymol system increases by more than two orders of magnitude.•A 3-fold increase of the solubilization power of CTAB is induced by N-methylglucamine.
