PURPOSE:To enhance temp. stability, by preparing an emulsifier composition from organically modified clay mineral obtained by treating water-swellable clay mineral with a quanternary ammonium salt type cationic surfactant and a nonionic surfactant. CONSTITUTION:Water-swellable clay mineral, an quaternary ammonium salt type cationic surfactant and a noinoic surfactant are dispersed in water or a low b.p. solvent such as acetone or lower alcohol under stirring to prepare a water in oil type emulsifier composition. The content of the quanternary ammonium salt type cationic surfactant is pref. 5-100g mg equivalent per 100g of water-swellable clay mineral and that of the noinionic surfactant is pref 5-100g per 100g of water-swellable clay mineral. As the water-swellable clay mineral natural one such as montomollilonite, saponite or hectrite is disignated. |
