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. An alkaline glycinate salt, such as sodium, potassium or zinc glycinate, may be added to the polyhydric alcohol prior to the addition of the antiperspirant salt solution in order to raise the pH of the recovered product to about 4.1 to 5.0.
