title: Influence of the purification of sodium dodecyl sulfate on the physical properties of solutions and O/W emulsions.
abstract: The effect of the purification of sodium dodecyl sulfate (SDS) has been studied in aqueous solutions and in o/w emulsions. The physical properties (surface tension, conductivity, light dispersion, viscosity, and granulometry) depend on the degree of purity of surfactant. This effect is less important within the emulsion technology when thickener or cosurfactant agents are added to the emulsion.
