ABSTRACT:
Disclosed is a process for making anhydrous compositions containing solubilized, enhanced antiperspirant active, which process comprises the steps of (A) heating an aqueous solution comprising from about 24% to about 55% by weight of a solubilized, non-enhanced, aluminum-containing antiperspirant active at a temperature of from 120.degree. C. to about 200.degree. C. for a period of time of from about 1 minute to about 15 minutes to form a solubilized, enhanced, aluminum-containing antiperspirant active; (B) adding an anhydrous solvent to the aluminum-containing solution at a weight ratio of the anhydrous solvent to the aluminum-containing antiperspirant actives of from about 1:2 to about 20:1; and C removing water from the anhydrous solvent-containing solution to form an anhydrous composition containing solubilized, enhanced, aluminum-containing, antiperspirant active. The process provides an improved method for making antiperspirant compositions containing solubilized, enhanced antiperspirant active.
