  • Low temperature process for making stable anhydrous solutions of antiperspirant active in selected 1,2-diol solvents
    Patent number: 6416750
    Abstract: Disclosed is process of making stable antiperspirant active solutions, which process comprises the steps of: (A) preparing an aqueous solution comprising an aluminum-containing antiperspirant active, water, and an anhydrous solvent having a solubility parameter of from about 9 (cal/cm3)0.5 to about 15 (cal/cm3)0.5; (B) spray-drying the aqueous solution to form a solid powder comprising aluminum-containing antiperspirant active and the anhydrous solvent; and (C) dissolving the solid powder in a second anhydrous solvent at a temperature of not more than 85° C., the second anhydrous solvent comprising a 1,2-diol solvent having at least 4 carbon atoms, to form a stable antiperspirant active solution comprising solubilized aluminum-containing antiperspirant active and the 1,2-diol solvent.
