Abstract
The solubilization of oily materials and/or oil dyes by water-soluble surfactants was studied in terms of the limit of solubilization, solubilizing power, cmc depression, viscosity, dielectric constants, electrical conductivity, electrophoresis, diffusion, surface tension and the heat of mixing. Differences in the solubilization mechanism and size of micelles due to different solubilizates, and the energy gap between solubilization and emulsion regions with increasing amount of solubilizate are discussed. Moreover, thermochromism and fading phenomena for solubilized solutions of oil dye are described.
