Abstract:
An anhydrous antiperspirant cream composition comprising(a) from about 5% to about 35% by weight of a particulate antiperspirant active;(b) from about 0.1% to about 20% by weight of a crystalline gellant;(c) from about 10% to about 80% by weight of an anhydrous liquid carrier for the crystalline gellant wherein the anhydrous liquid carrier has a solubility parameter of from about 3 to about 13; and(d) from about 0.001% to about 5% by weight of an anhydrous liquid surfactant wherein the liquid surfactant is selected from the group consisting of nonionic surfactants, amphoteric surfactants, and combinations thereof;wherein the composition has a penetration force value of from about 75 gram.multidot.force to about 400 gram.multidot.force, a delta stress value of from about 300 dyne/cm.sup.2 to about 8,000 dyne/cm.sup.2 as measured after extrusion of the composition through a shear force delivery means, and a static yield stress value of from about 1,000 dyne/cm.sup.2 to about 63,000 dyne/cm.sup.2 as measured after extrusion of the composition through a shear force delivery means.
