A topical antiperspirant composition or preparation consisting essentially of an effective antiperspirant amount of a non-toxic water-insoluble occlusive film-forming polymer, and a method of reducing perspiration by applying such a composition to the skin of a subject in the area in which it is desired to reduce perspiration, is disclosed. A preferred polymer is an alkyl olefinic acid amide/olefinic acid or ester copolymer, e.g., octylacryl amide or propenamide/acrylates copolymer, alone or in combination with a PVP-linear alpha-olefin copolymer, especially a PVP/Eicosene copolymer or other water-repellant polymer. Normally-employed mineral salts, such as aluminum and zirconium chlorohydrate, may be included in the composition but, since not essential, may be employed in reduced amounts, if present. The composition may take various usual forms, such as solutions, suspensions, or other liquid forms, dab-ons, roll-ons, or stick forms, according to the convention of the art, with stick forms being preferred from the standpoint of extended and improved effectiveness. Evaporation of non-toxic solvent, in which the polymer may be dissolved or dispersed, leaves a cosmetically-acceptable and usually clear transparent antiperspirant film which is effective for its intended purpose.
