  • Patent number: 6187300
    Abstract: Disclosed are anhydrous antiperspirant cream compositions that have improved wash-off performance and good antiperspirant efficacy, which compositions have a penetration force value of from about 75 gram·force to about 500 gram·force, a delta stress value of from about 300 dyne/cm2 to about 8,000 dyne/cm2 as measured after extrusion of the composition through a shear force delivery means, and a static yield stress value of at least about 1,000 dyne/cm2 as measured after extrusion of the composition through a shear force delivery means. These compositions comprise from about 0.1% to about 20% by weight of a crystalline gellant, 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, from about 5% to about 35% by weight of a particulate antiperspirant active, and from about 0.
