In order to make detailed analysis of the phase inversion of the emulsified system by a nonionic surfactants, temperature of phase inversion was calculated from the electric resistance-temperature curve by measuring changes in the electric resistance with variation in temperature, and Winsor's theory in the solubilized system from changes in the condition of a system was proved to be applicable to the emulsified system using a non-ionic surfactant. In the present series of work, some factors contributing to the phase inversion temperature during the preparation of an emulsified system were examined. Changes in the temperature of phase inversion in the standard emulsified system were measured while changing the ratio of oil and water phases, concentration of the surfactant, and component of the oil phase, using an apparatus devised in this laboratory. It was found that, by the application of Winsor's classification on the solubilized system, it became possible to make a quantitative examination of factors contributing to the phase inversion of an emulsified system.
