The critical micelle concentrations (CMC) of sorbitan monopalmitate and sorbitan monooleate have been determined at 25/sup 0/C in pure nonaqueous solvents like benzene and carbon tetrachloride, and also in a solvent mixture comprised of diesel oil and paraffin oil (50:50). An attempt has been made to correlate CMC data with the surfactant solvent interaction concept and the effect of the aromatic vs. aliphatic nature of the solvent is highlighted. The importance of unsaturation in the hydrophobic moiety in bringing up the CMC also is indicated.
