Abstract: A foaming antiperspirant or deodorant composition comprising: a. an oil and water emulsion; b. a first blowing agent with at least 0.1% water solubility at 20° C.; and c. a second blowing agent with a water solubility of at most 0.01% at 20° C.

Abstract: A foaming antiperspirant or deodorant composition comprising: a. an oil in water emulsion comprising: i. a first oil phase comprising one or more emollients; ii. a second oil phase comprising one or more emollients; wherein the second oil phase emollients have at most 5% solubility in the first oil phase emollients; iii. an antiperspirant or deodorant active; iv. one or more nonionic emulsifier; and v. a fragrance; and b. at most about 15%, by weight of the composition, of a blowing agent.

Abstract: The present invention comprises a process of preparing a solution of an enhanced efficacy aluminum antiperspirant salt in a polyhydric alcohol by(a) providing an aqueous solution consisting essentially of about 5% to about 18% by weight of an enhanced efficacy aluminum antiperspirant salt in water, the enhanced efficacy aluminum antiperspirant salt having been prepared in situ without having been dried to a solid powder;(b) mixing the aqueous solution with a sufficient amount of a liquid polyhydric alcohol to provide a mixed solution which has an antiperspirant salt to polyhydric alcohol ratio of about 1:4 to about 1.2:1; and(c) rapidly evaporating the water from the mixed solution under vacuum to provide a final liquid polyhydric alcohol solution containing about 20 to 50% enhanced efficacy aluminum antiperspirant salt and about 2 to 16% water, with the balance being polyhydric alcohol.

Abstract: A composition of zirconyl hydroxy chloride and aluminum chlorhydroxide in stable solid form having improved antiperspirant efficacy when dissolved in water is made by heating a 2-20% by weight aqueous solution containing at least the aluminum chlorhydroxide component of the composition at a temperature of at least 50.degree. C. until the ratio of the height of peak 4 at Kd=0.7 to that of peak 3 at Kd=0.5 as measured by gel permeation chromatography on cross-linked dextran is at least 2:1, then subjecting the solution to rapid drying to solid form.
