ABSTRACT:
The present invention comprises stabilizing aqueous solutions of aluminum zirconium based salts with a water soluble amino acid, especially glycine, wherein the Zr:glycine weight ratios used to form solutions of the active itself or used to form cosmetic compositions made according to this invention are in the range from 1:1.2 to 1:5, particularly 1:2 to 1:4, and more particularly in the range of 1:2 to 1:3 on a weight:weight basis. By reducing the polymerization of small zirconium species with an elevated amount of amino acid(s), the efficacy of the antiperspirant salt is maintained.
