MEASUREMENTS OF THE KRAFFT POINT SURFACTANT MOLECULAR-COMPLEXES - INSIGHTS INTO THE INTRICACIES OF SOLUBILIZATION

Of the surfactant molecular complexes widely I obtained by us in the s ystem of quaternary ammonium cationic surfactants such as CTAB (cetylt rimethylammonium bromide) and various aromatic substances as additives , we have already reported several solution characteristics which reve al them to be novel surfactant species. In the report; it was disclose d that they had their own critical micelle concentrations (cmc's) diff erent from those of the mother surfactants and that the solubilization of such surfactants solubilizates (additives) was just the dissolutio n of the surfactant. complexes gene rated in the solubilization proces ses, In this successive study through measurements of the Krafft point of the surfactant molecular complexes, it will again be clarified tha t the ''solubilization'' is not a special phenomenon but merely one wh ich is recognized to be the dissolution of those surfactant complexes like that of any other crystalline material, The facts that the solubi lization is obviously operative even at such a low surfactant concentr ation as below its cme and that the presence of surfactants far above their cme suppresses the solubilization to such an extent that it is m uch lower than that of the solubility of the solubilizates in pure wat er might be explained only by the novel concept we already presented, by which the obsolete theory for the solubilization so far should be s ubstituted.
