Viscosity, conductivity, density, and fluorescence quenching studies were conducted in aqueous micellar solutions at 25.0° C of sodium alkyl sulfoacetates and sodium dialkyl sulfosuccinates in a comparison of one-tailed and two-tailed surfactant systems. The hexyl, octyl, and decyl members of the former group and the dihexyl and dioctyl members of the latter group were investigated. The results indicated that the sulfoacetates most likely form ...
