Abstract
Abstract Uniform, clear gelled antiperspirant compositions, free of waxes and conventional gelling agents are disclosed. The gel emulsions comprise in combination a volatile silicone fluid, a silicone emulsifier, a destabilizing auxillary emulsifier, water, a non-volatile emollient, a coupling agent, an active antiperspirant component and ancillary agents.

Claim 1
Independent Claim
160 words
A clear gelled antiperspirant composition free of waxes and gelling agents containing: (a) from about 10% to about 25% by weight of a cyclomethicone-dimethicone copolysilicone fluid having a viscosity of 25 C. of 600-2000 cps; (b) from about 10% to about 30% by weight of a volatile polydimethylcyclosiloxane exemplified by the formula [CCH 3 ) 2 SiO] x wherein x is an integer of from 4 to 6; (c) from about 1% to about 10% by weight of a non-volatile emollient material selected from the group consisting of fatty acid esters, fatty acid ethers, linear silicone fluids, polyalkylene glycols, lanolin, lanolin alcohol, mineral oil and mixtures thereof; (d) from about 2% to about 10% by weight of a coupling agent selected from the group consisting of low molecular weight alcohols and glycols; (e) from about 15% to about 25% by weight of an active antiperspirant material selected from the group consisting of aluminum chlorohydrates, aluminum zirconium chlorohydrates and complexes thereof.
