2082813 9118587 PCTABS00008 Disclosed are clear sprayable liquid antiperspirant compositions having viscosities of less than about 15 centistokes, comprising: an antiperspirant salt which is soluble, and which will remain soluble, in a monohydric alcohol solvent; high levels (30 % or greater) of emollient esters and silicone materials, having viscosities of from about 0.65 centistokes to about 50 centistokes, and solubility parameters of from about 4 to about 10; a surfactant solubilizer which is selected from the group consisting of ethoxylated or propoxylated nonionic surfactants having an HLB of from about 5 to about 18, and mixtures thereof, such that the average HLB of the solubilizer is from about 8 to about 14; and relatively low levels (less than about 50 %) of a monohydric alcohol solvent: wherein the antiperspirant compositions comprise no more than about 5 % water. These antiperspirant compositions provide excellent antiperspirancy and cosmetic in-use properties. They are non-sticky, non-greasy, and quick drying. They stain clothing less than other spray-on liquid antiperspirants. These compositions go onto the skin as a clear spray and leave no white, chalky, residue on skin upon dry down. These antiperspirant compositions also remain stable over time and a broad range of physical conditions, especially ambient temperatures.
