ABSTRACT:
Encapsulated aluminum-zirconium salt compositions are produced by combining and heating an aqueous aluminum- zirconium salt selected from aluminum-zirconium halohydrates and mixtures thereof; a hydrophobic liquid; and a carboxylate. The mixture is heated until substantially all of the free water has been removed. The encapsulated aluminum-zirconium salts precipitate out after the removal of the water. The encapsulated aluminum-zirconium salts are useful in deodorant and antiperspirant compositions.
