Abstract

Disclosed are anhydrous gel deodorant compositions comprising from about 0.001% to about 50% by weight of deodorant active, fragrance, or combination thereof, from about 0.01% to about 20% by weight of a gellant; from about 1% to about 50% by weight of a nonpolar volatile solvent having a solubility parameter of less than 8.0 (cal/cm.sup.3).sup.0.5, a vapor pressure of from about 0.01 mm Hg to about 6 mm Hg at 25.degree. C., and a boiling point at 1 atm of less than about 250.degree. C.; from about 1% to about 15% by weight of a polar solvent having a solubility parameter of from 12.5 (cal/cm.sup.3).sup.0.5 to about 25 (cal/cm.sup.3).sup.0.5 and optionally a moderately polar solvent having a solubility parameter of from about 8.0 (cal/cm.sup.3).sup.0.5 to less than 12.5 (cal/cm.sup.3).sup.0.5, preferably 1,2-hexanediol. Other preferred embodiments include those which contain combinations of triclosan and triclocarban for improved deodorant efficacy.
