Three anionic surfactants (Na-octysulfoacetate (A8), Na-dodecylsulfoacetate (A12), and Na-cetylsulfoacetate (A16) were prepared from alkyl bromoacetate. Several studies were carried out with aqueous surfactant solutions including surface tension, and electrical conductivity measurements. Surface properties, in particular, critical micelle concentration (CMC), effectiveness (ΠCMC), efficiency (Pc20), maximum surface excess (Γmax), and minimum surface area (Amin) were investigated at different concentrations at 20, 35 and 50°C, respectively. Free energies, enthalpies, entropies of micellization, and adsorption of the surfactants in the aqueous solution were studied.

Viscosity, conductivity, density, and fluorescence quenching studies were conducted in aqueous micellar solutions at 25.0 deg 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 spherical micelles with aggregation numbers 20 for hexyl, 42 for octyl, and 70 for decyl with three methods for size determination giving concordant results.For the sulfosuccinates, the aggregation numbers from fluorescence quenching were 38 for the dihexyl and 56 for the dioctyl in agreement with the results from the conductance technique which means that spherical micelles are likely formed also.Volume changes on micellization were obtained for the sulfoacetates.
