| 摘要 |
Antiperspirant stick compositions are described which comprise an aqueous solution of an astringent dispersed in a solid matrix comprising a volatile, water-insoluble liquid; a polydiorganosiloxane-polyoxyalkylene copolymer; a solid alkanoic acid; a waxy ester; and optionally containing a solid alkanol. A preferred embodiment comprises an aqueous solution of aluminum chlorhydrate dispersed in a solid matrix comprising cyclopolydimthylsiloxanes as the volatile liquid. These compositions are stable to separation in the molten state and provide non-leaking sticks of controllable softness when solidified by cooling.
