Abstract
The critical micelle concentration (CMC) of mag-nesium soaps in n-propanol and butanol have been determined by viscosity measurements. The equations of Vand and Moulik are applicable only above CMC. The parameters of equations may be used to calcu-late the viscosity of soap solutions in the concentra-tion range in which the equations hold good. The temperature effect on viscous flow follows Arrhenius’ equation. The effect of soap concentration on fluidity of soap solutions has been discussed in the light of Eyring’s equation and the activation param-eters of viscous flow, ΔH*, ΔS*, and ΔG* with respect to the solvent have been calculated.
