ABSTRACT:
This invention pertains to a method of making non-aqueous solutions of aluminum and aluminum-zirconium compounds. The non-aqueous solutions are produced by: (A) protonating a hydroxylated solvent, such as ethanol or propylene glycol, by adding an acid selected from ZrOCl.sub.2, ZrO(OH)Cl, ZrCl.sub.4, AlCl.sub.3, HCl, HI, HBr, HNO.sub.3, and mixtures thereof to the hydroxylated solvent; and (B) adding at a controlled rate to protonated solvent aluminum chlorohydrate, Al.sub.2 (OH).sub.a Cl.sub.6-a, wherein a has the value of greater than 0 but less than 6; until the desired solution is formed. The non- aqueous solutions are useful in antiperspirant compositions.
