Abstract: Activated aluminum sesquichlorohydrate (AASCH) powders prepared by (a) diluting the concentrated aluminum sesquichlorohydrate (ASCH) solution to from about 10% to about 25% by weight, (b) heating the diluted solution to obtain a Band III polymer concentration of at least about 20% and a Band IV polymer concentration of at least about 15%, (c) drying the heated solution to powders, and (d) optionally screen or light mill the powders to free flowing spherical particles are disclosed.

Abstract: Antiperspirant active composition of enhanced efficacy containing a zinc salt and an efficacy enhancing agent selected from the group consisting of amino acid, hydroxy acid and a mixture thereof is disclosed. Specifically, a shelf-stable antiperspirant active solution containing an aluminum or aluminum-zirconium salt, a zinc salt, and the efficacy enhancing agent, which maintains the peak 4 concentration of at least 10% upon aging is disclosed. The present invention also includes methods of making the antiperspirant active solutions and formulations containing same.
