  • Publication number: 20030026773
    Abstract: Disclosed are liquid anhydrous antiperspirant emulsions, comprising (a) an external phase containing a non-volatile hydrophobic liquid; and (b) an internal phase containing an antiperspirant active solubilized in a polar solvent; wherein the emulsions have an external to internal phase ratio of at least about 1.25 and a weight ratio of the non-volatile hydrophobic liquid to the combination of antiperspirant active and polar solvent in the internal phase of at least about 0.33. The anhydrous antiperspirant emulsions provide little or no visible residue on the skin and also provide for a smooth, dry, non-sticky, skin-feel during and after application. These emulsions are especially useful when delivered from a roll-on applicator.

  • Patent number: 6149897
    Abstract: Disclosed is a process for making anhydrous compositions containing solubilized, enhanced antiperspirant active, which process comprises the steps of (A) heating an aqueous solution comprising from about 24% to about 55% by weight of a solubilized, non-enhanced, aluminum-containing antiperspirant active at a temperature of from 120.degree. C. to about 200.degree. C. for a period of time of from about 1 minute to about 15 minutes to form a solubilized, enhanced, aluminum-containing antiperspirant active; (B) adding an anhydrous solvent to the aluminum-containing solution at a weight ratio of the anhydrous solvent to the aluminum-containing antiperspirant actives of from about 1:2 to about 20:1; and C removing water from the anhydrous solvent-containing solution to form an anhydrous composition containing solubilized, enhanced, aluminum-containing, antiperspirant active.
