  • Patent number: 4414200
    Abstract: A powder stick composition for topical application, and particularly a powder stick containing an anti-perspirant as an active ingredient. The stick is produced by incorporating an active ingredient, a finely divided inert filler, and a fatty alcohol with a siloxane at an elevated temperature to form a slurry. The slurry is then molded into stick form at atmospheric pressure, and the molded stick is dried to evaporate a major portion of the siloxane. The resulting stick is firm, has a uniform distribution of the active ingredient throughout the cross section and has excellent pay-off characteristics.
