  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.

  本发明旨在提供一种溶胶组合物、一种油性凝胶组合物和一种 W/O 型乳液，该组合物由有机改性粘土矿物组成，在油中具有平均厚度为 0.1 微米或以下、平均主轴为 0.5 至 50 微米的板状颗粒结构。研究表明，在有非离子表面活性剂存在的情况下，通过将有机改性粘土矿物的集合体在油中洗脱成板状颗粒，增稠和胶凝能力会显著提高。此外，由于 W/O 型乳液的稳定效果极佳，因此可以通过降低具有板状颗粒结构的有机改性粘土矿物和非离子表面活性剂的用量，在低粘度条件下提供具有高乳液稳定性的 W/O 型乳液。此外，还可以通过使用具有 COOH/OH 基团的油来降低组合物的粘度，同时保持乳液稳定性。这样，就能获得一种在低粘度下具有出色稳定性的乳液，并且在使用时具有出色的感觉，如涂抹性和新鲜度。

  Structured surfactant systems with solid suspending properties comprise a substantially non-aqueous liquid continuous phase and a structuring surfactant capable of forming an L&agr; phase in said continuous liquid phase at a concentration between 10 and 20% by weight solid surfactant preferably comprising at least two hydrophobic C7-30 aliphatic groups per molecule, said groups preferably comprising bent chain groups such as cis monounsaturated alkenyl e.g. erucyl or singly branched alkyl e.g. isopalmityl.
