Claim:
1. A method of making activated aluminum sesquichlorohydrate (AASCH) powders consisting of: (a) diluting a concentrated aluminum sesquichlorohydrate (ASCH) solution to about 1% to about 25% by weight, (b) heating the diluted solution to activate the solution, (c) drying the activated solution to form the activated aluminum sesquichlorohydrate (AASCH) powders, (d) optionally adding a buffering agent prior to the drying, and (e) optionally sieving or milling the AASCH powders, wherein the activated AASCH powders have an Al:Cl ratio of from about 1.60 to about 1.90, a Band III polymer concentration of at least 20%, and a Band IV polymer concentration of at least 15%, wherein no acid or acidic aluminum chloride is introduced after the heating of the diluted solution.
