  • Method of making polyhydric alcohol solutions of enhanced efficacy antiperspirant actives
    Patent number: 5939057
    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.
    Type: Grant
    Filed: June 13, 1997
    Date of Patent: August 17, 1999
