PROBLEM TO BE SOLVED: To provide an organic modified clay mineral-based thickener/gelling agent which exhibits an excellent thickening/gelling ability to oils, to provide an oily gel composition using the same, to provide an organic modified clay mineral-based emulsifier which can exhibit excellent temporal stabilizing effects such as an effect for inhibiting the temporal coagulation/uniting of emulsified particles, when using a W/O emulsion, to provide a W/O emulsion using the emulsifier, to provide an organic modified clay mineral-based emulsifier which can exhibit a W/O emulsion stabilization effect even in a low viscosity, and also to provide a W/O emulsion using the emulsifier.SOLUTION: An oily gel composition contains (i) an organic modified clay mineral having an average thickness of &le0.1 &mum, an average major axis of 0.5 to 50 &mum, (ii) a nonionic surfactant, and (iii) an oil. A W/O type emulsion composition and a cosmetic each use the oily gel composition.COPYRIGHT: (C)2008,JPO&INPIT【課題】 油分に対して優れた増粘・ゲル化能を発揮する有機変性粘土鉱物系増粘・ゲル化剤ならびにこれを用いた油性ゲル組成物、また、W/O乳化物に用いた場合に経時的な乳化粒子の凝集・合一を抑制するなどの優れた経時安定化効果を発揮し得る有機変性粘土鉱物系乳化剤ならびにこれを用いたW/O乳化物、さらには低粘度においてもW/O乳化安定性化効果を発揮し得る有機変性粘土鉱物系乳化剤ならびにこれを用いたW/O乳化物を提供する。【解決手段】 (i)平均厚さが0.1μm以下、平均長径が0.5~50μmである板状粒子構造を有する有機変性粘土鉱物、(ii)非イオン性界面活性剤、及び(iii)油分を含有する油性ゲル組成物、また、これを用いたW/O型乳化組成物及び化粧料。【選択図】 なし
