Abstract
Abstract A water-in-oil type emulsified composition containing a water-swellable clay mineral, a nonionic surfactant, an oil component, and water as the essential constituents or containing a water-swellable clay mineral, a quaternary ammonium salt type cationic surfactant, one or two more kinds of polyoxyalkylene modified organopolysiloxane, an aqueous phase, and an oil phase containing one or two or more kinds of organic silicone resin comprising the units of the formula: RnSiO.sub.(4-n)/2 wherein R is a hydrocarbon group having 1 to 6 carbon atoms or a phenyl group, and n represents a value of 1.0 to 1.8, and a water- and polyhydric alcohol-in-oil type emulsified composition containing an oil phase containing a polyoxyalkylene modified organopolysiloxane, a water-swellable clay mineral, a quaternary ammonium salt type cationic surfactant and a silicone oil, water, and a polyhydric alcohol.
