ABSTRACT:
Alkali metal and ammonium zirconyl carbonates (AZC) may be used as active antiperspirant ingredients when converted to complexes with various acidic antiperspirant agents, including particularly the highly acidic zirconium compounds. The acidic antiperspirant agent activates the zirconium in the zirconyl carbonate to an acidic, active antiperspirant species. The zirconyl carbonate comprises about 2 to 35 weight percent of the complex, and the antiperspirant activating agent is present in such an amount that the pH of a 5 to 20 weight percent aqueous solution of the complex will be about 3 to 6. Potassium and ammonium zirconyl carbonates are preferred, but sodium may also be used if the complex is kept in solution. The acidic, antiperspirant activating agent is preferably a zirconium oxy salt or zirconium hydroxy salt, such as a zirconium hydroxy halide. However, other water soluble, polyvalent metal salts of strong acids may be used, particularly aluminum halides and basic aluminum compounds. In addition, the complex may include organic complexing agents such as urea, amino acids and hydroxy carboxylic acids. The complexes may be used in various conventional antiperspirant forms, including aqueous solutions, aerosol sprays, powder-in-oil aerosol sprays, creams, lotions, cream sticks, etc.
