  • 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.
