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.

Clear antiperspirant stick containing dibenzylidene alditol

A clear gel cosmetic stick includes a liquid vehicle, a dibenzylidene alditol as a gelling agent, an antiperspirant salt dissolved in the liquid vehicle, and a hydroxyalkyl cellulose co-gellant. The cosmetic stick comprises in percent by weight about 70% to about 95%, preferably 75 to 92%, of a liquid vehicle comprising a polyhydric alcohol having from 3 to 6 carbon atoms and from 2 to 6 hydroxyl groups, about 0.5% to about 1.5%, preferably 0.7% to 1.3%, of a dibenzylidene alditol, about 3% to about 22%, preferably 6% to 15%, of an antiperspirant salt dissolved in said vehicle, and about 0.1% to about 0.5%, preferably 0.2% to 0.4%, of a hydroxyalkyl cellulose. Preferably the liquid vehicle is substantially free of monohydric alcohol and is also substantially free of strong alkali such as NaOH and KOH. Preferably the cosmetic stick will have a pH greater than 4.4, more preferably greater than 4.7, a turbidity of less than about 120 NTU, more preferably less than 100 NTU, and a hardness of about 60 to 150. By lowering the dibenzylidene alditol level to 1.5% or lower, the clarity and odor characteristics of the stick are greatly improved. The hardness of the stick is maintained by the addition of the hydroxyalkyl cellulose.

A clear gel cosmetic stick includes a liquid vehicle, a dibenzylidene alditol as a gelling agent, an antiperspirant salt dissolved in the liquid vehicle, and a chelating agent. The cosmetic stick comprises in percent by weight about 40% to about 95% of the liquid vehicle, from about 0.1% to about 5% of the dibenzylidene alditol, from about 0.5% to about 25% of the antiperspirant salt, and from about 0.05% to about 3% of the chelating agent. The cosmetic stick is preferably substantially free of alkaline gelling agent stabilizers such as NaOH and KOH.

A conditioning shampoo is provided in the form of an aqueous solution having a pH of about 5 to 6 and which includes, in percent by weight of the total composition:

Conditioning shampoo

An improved hair conditioning composition comprises water, a cationic hair conditioning agent, a nonionic surfactant, a fatty alcohol, and an extremely small but effective amount of a fluorosurfactant, the hair conditioning composition preferably comprising from about 0.5 to 5 percent of the cationic hair conditioning agentm, up to about 5 percent of the nonionic surfactant, from about 0.5 to 10 percent of one or more fatty alcohols, less than 0.05 percent of the fluorosurfactant, and water.
