The critical micelle concentration, degree of ionization, and ionization constant of samarium caproate in alcohols (methanol, ethanol, propanol‐1, butanol‐1 and pentanol‐1) were determined by using conductometric measurements. The results show that the soap behaves as simple electrolyte in dilute solutions below the CMC. The viscosity results of samarium soap have been explained in terms of equations proposed by Einstein, Vand, Moulik and Jones‐Dole. The critical micelle concentration (CMC) was found to decrease with increasing dielectric constant of the solvent.
