Cationic And Anionic Surfactants

Interactions taking place in aqueous solutions when cationic surfactants, alkyl trimethyl ammonium bromides (CnTABs, dodecyl or octadecyl), are added to solutions of anionic surfactants, like alkyl dithiocarbonates (xanthates, hexyl or nonyl) and dodecyl sulfate or laurate ions, result either in the formation of 1:1 complexes or in mixed micelles. Infrared and ultraviolet spectra show that complexes are largely ionic, with some perturbations of bonds in anions and a limited hydrolysis in the case of laurate ions.

General Method

Equilibrium vesicles, those which are the stable form of aggregation and form spontaneously on mixing surfactant with water, have never been demonstrated in single component bilayers and only rarely in lipid or surfactant mixtures. Designing a simple and general method for producing spontaneous and stable vesicles depends on a better understanding of the thermodynamics of aggregation, the interplay of intermolecular forces in surfactants, and an efficient way of doing structural characterization in dynamic systems.
