ABSTRACT:
Anti-perspirant complexes are provided which comprise a combination of a basic aluminum compound, a zirconium compound and an amino compound which may be an alkaline or hydroxy salt of an amino acid in which the number of amino groups is equal to the number of carboxyl groups in the molecule. 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 basic aluminum compound may be any of the usual basic aluminum anti-perspirant salts, particularly the basic aluminum halides, and the zirconium compound may be a zirconium oxy salt and/or zirconium hydroxy salt. The amino salts may be soluble or insoluble, and particularly preferred compounds include the alkaline and alkaline earth glycinates, aluminum dihydroxy or monohydroxy glycinates, and aluminum-magnesium-hydroxy-glycinate compounds. 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.
