Aqueous micellar solutions of dodecyl- and hexadecyltrimethylammonium bromides, hexade- cylpyridinium bromide and chloride, domiphen bromide ((dodecyldimethyl- N -2-phenoxyethyl)ammonium bromide), hexadecyltriphenylphosphonium bromide, and sodium dodecyl sulfate have been investigated using dynamic light scattering. A local increase in the diffusion coefficient has been discovered...
Dynamic light scattering and capillary viscometry have been employed to study aqueous micellar solutions of nonionic (pentaoxyethylene dodecyl ether) and ionic (decyl-, dodecyl-, and tetradecyltrimethyammonium bromides) surfactants in a wide concentration range covering the first and second critical micelle concentrations (CMC 1 and CMC 2 , respectively). The concentration...
