SOLUTION BEHAVIOR OF ANIONIC SURFACTANT MOLECULAR-COMPLEXES

We have already reported the solution behavior as examined by electric al conductivity for cationic surfactant molecular complexes composed o f quaternary ammonium salts such as CTAB and various aromatic additive species such as phenols and amines. By the same electrical conductivi ty method, we have obtained many valuable results which establish the newly obtained anionic surfactant molecular complexes to be novel surf actant species displaying their own characteristic CMCs and Krafft poi nts different from those of their mother surfactants, Through the solu tion behavior, furthermore, we could deduce that a solubilized solutio n system that was of molar composition equal to that of the complex in the surfactant and the solubilizate (additive) was perfectly identica l to the dissolution system of the complex, The facts satisfactorily c onfirmed that a solubilized solution system was only the dissolution s ystem of the complex which spontaneously resulted in the process of so lubilization.
