Abstract
Disclosed is an anhydrous topical antiperspirant composition comprising a dermatologically acceptable carrier and a perspiration reducing effective amount of a particulate antiperspirant salt suspended in the carrier. The antiperspirant salt comprises an aluminum-zirconium chlorohydrate having a metal to chloride ratio between about 0.9 and about 1.3. The composition also includes, separate from the antiperspirant salt, a stabilizing basic material in an amount sufficient to prevent degradation of the antiperspirant composition or to minimize acid odor. Also disclosed is a method of reducing perspiration from human skin by applying the aforementioned topical composition.
