Abstract
Antiperspirant emulsion compositions are described which comprise an aqueous solution of an astringent agent; a volatile, water-insoluble liquid; a polydiorganosiloxane-polyoxyalkylene copolymer; an oil-in-water type surfactant; and a water-in-oil type surfactant. A preferred embodiment comprises an emulsion of aqueous aluminum chlorhydrate in cyclopolydimethylsiloxanes as the volatile fluid. These compositions have improved efficacy as measured by their drying times.
