Abstract
Abstract An antiperspirant formulation containing an extract from the aloe vera plant that prevents irritation in most persons sensitive to the metallic salts in common use as antiperspirants. A basic formulation consists of a 50% aqueous metallic salt astringent solution of 85 parts by weight and the natural gel of aloe vera of 15 parts by weight. The preferred metallic salt is aluminum chlorohydroxide. The salt may be combined with various other anti-microbial agents, drying agents, fragrances and the like with aloe vera extracts either in the natural gel form or as aloe extract oil to provide formulations for manual or aerosol sprays, roll-ons, creams and the like. The antiperspirant of the invention permit use by most persons formerly unable to tolerate many antiperspirants due to irritation of the skin.
