Anti-perspirant complexes are provided which comprise a combination of a basic aluminum compound, a zirconium compound and a hydroxy carboxylic compound which may be a non-toxic salt of a hydroxy carboxylic acid, a non-toxic salt of an aluminum chelate of a hydroxy carboxylic acid, a codried mixture of aluminum hydroxide with a non-toxic salt of an aluminum chelate of a hydroxy carboxylic acid, or mixtures thereof. The various components are present in the complex in amounts such that the Al/Zr mol ratio is about 10:1 to 1:10 and the pH of an aqueous solution containing 5 to 15 weight percent of the complex (based on the oxides of aluminum and zirconium) is at least about 3. The complexes may be used in conventional anti-perspirant forms, including aqueous solutions, aerosol sprays (including powder-in-oil aerosol sprays), as well as creams, lotions and cream sticks. |
