ABSTRACT:
Encapsulated aluminum salts are produced by combining and heating an aqueous aluminum salt selected from aluminum halohydrate, aluminum nitrohydrate 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 salts precipitate out after the removal of the water. The encapsulated aluminum salts are useful in deodorant and antiperspirant compositions.
