ABSTRACT:
Unusually effective anti-perspirant compositions are provided by forming an astringent complex of a basic aluminum compound, a zirconium compound and a trace amount of an alkaline earth metal salt. The alkaline earth metal may be either calcium or magnesium or both, but preferably magnesium, and may be added as any of the usual salts such as halides, carbonate, oxide, hydroxide, etc. The basic aluminum compounds may be any of the usual basic aluminum anti-perspirant salts, particularly basic aluminum halides, and the zirconium compound may be a zirconium oxy salt and/or zirconium hydroxy salt. The complex should have an Al/Zr mole ratio of about 10:1 to 1:10, and preferably about 4:1 to 1:1, and the pH of an aqueous solution containing 5 to 15 weight percent of the complex (based on the oxides of aluminum and zirconium) should be 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.
