Sol Composition Containing Organically Modified Clay Mineral Having Platy Particle Structure, Oily Gel Composition, And W/O Type Emulsion Composition Containing The Same

摘要

The present invention is to provide a sol composition, a oily gel composition, and a W/O type emulsion comprising an organically-modified clay mineral, having a platy particle structure with an average thickness of 0.1 μm or less and an average major axis of 0.5 to 50 μm in oil. It showed that the thicknening and gelling ability becomes significantly high, under the presence of a nonionic surfactant, by elaminating the aggregate of organically-modified clay mineral into platy particles in oil. In addition, because the stabilizing effect of a W/O emulsion is excellent, it is possible to provide a W/O emulsion with high emulsion stability at low viscosity by lowering the usage of the organically-modified clay mineral with a platy particle structure and the nonionic surfactant. Furthermore, it is possible to lower the viscosity of the composition, while maintaining the emulsion stability, by using an oil having COOH/OH groups. Thus, an emulsion with excellent stability at low viscosity and with an excellent feeling in use, such as spreadability and freshness, can be obtained.
