ABSTRACT:
The present invention is directed to a composition comprising an antiperspirant salt suspended in a carrier vehicle thickened with a silicone latex. The composition typically comprises about 50 to 90% carrier vehicle, which is advantageously substantially comprised of a volatile silicone, about 3 to 30% antiperspirant salt, which is typically an aluminum chlorohydrate or aluminum-zirconium chlorohydrate, and about 3-25% silicone latex. Preferably the composition will contain an auxiliary thickening agent such as a fumed silica, hydrated silica or trihydroxystearin, typically in an amount of 0.01 to 10%. The composition will preferably have a viscosity of about 12,000 to 20,000,000 cP. The present invention also embraces an apparatus for delivering the above-described composition when formulated with a medium viscosity of about 12,000 to 50,000 cP, said apparatus having a porous dome with a porosity of about 150 .mu.m to 400 .mu.m through which the composition is delivered.
