  • Patent number: 3963833
    Abstract: The development of perspiration is inhibited by topical application of 3-phenyl-3-carbo-(beta-di-lower alkylamino)-lower alkoxy-2,3-dihydrobenzofuran or a salt thereof, preferably the hydrochloride, and an antiperspirant aluminum, zinc, or zirconium salt, preferably aluminum chlorohydrate or aluminum chloride. The compositions applied may be aqueous, preferably including a surface active agent, such as a nonionic synthetic surface active compound of poly-lower alkylene oxide, or they may be non-aqueous, as in "aerosol" powder sprays.
