Conclusions 1. The organic ions of antibiotics (tetracycline, hydroxytetracycline, and chlorotetracycline) in aqueous acidic solution form associates (at concentrations above 10−4 M), the size of which, like surfactants, reaches tens of molecules. The associates, like the surfactant micelles, are probably formed as a consequence of the hydrophobic interaction between molecules. 2. The viscosity of the solutions decreases during the formation of an organic ion-polyelectrolyte complex in the case of associated hydroxytetracycline and cetylpyridinium bromide ions and changes little for unassociated triethylbenzylammonium ions. This is explained by the interaction of ions among themselves (associations) in the polymer-bonded state.
