Abstract

The invention is a clear, elastomer-free, gel composition comprising: (a) 0.1-25 weight % of an antiperspirant active having a low metal to chloride ratio in the range of 0.9-1.3: 1; (b) 9-23.95 weight % of one or more volatile silicones having a flash point of 100 degrees C or less; (c) 0.05-0.5 weight % of a silicone surfactant having an HLB value≦8; (d) 30-70 weight % water; (e) 0-50 weight % selected water soluble organic solvents; and (f) 0-10 weight % of an emollient; wherein the composition is a liquid gel having a viscosity in the range of 5-50,000 centipoise and a ratio of oil phase to water phase in the range of 10:90 to 24:76.
