Abstract

Abstract Disclosed are liquid antiperspirant compositions useful for both roll-on and aerosol antiperspirant applications. The compositions have reduced incidence of in-use skin irritation. The compositions comprise from about 10% to about 70%, by weight, of an antiperspirant active material, from about 1% to about 15%, by weight, of a suspension agent, from about 25% to about 75%, by weight, of a non-volatile silicone fluid component, and no more than about 15%, by weight, of volatile silicone fluid. In aerosol embodiments, the compositions can comprise the above composition as a concentrate in combination with an aerosol propellant.
