Data have been accumulated on the physico-chemical properties such as solubility, micelle formation, and solubilization in nonaqueous ionic surfactant solutions, but information on nonionic surfactants solutions is limited; thus, general information on the solubility behavior of nonionic surfactants in nonaqueous systems could not be obtained from previous publications. In order to obtain reliable information on the solubility behavior of nonionic surfactants in nonpolar media, glycerol and sorbitan monofatty acid esters, which have homogeneous or pure state, were utilized, and the measurements of the solubility and the vapor pressure lowering were conducted at varying temperatures. The critical solution temperature, critical aggregating or micellar concentration and aggregate weight estimated from the measurements were examined by varying the hydrocarbon chain length of surfactants, the solvent, and the temperature.
