  • Patent number: 6274127
    Abstract: Disclosed are non-adhesive antiperspirant compositions comprising a water or sweat-reactive monomer as the antiperspirant active, an anhydrous carrier, and an optional polymerization inhibitor, wherein the compositions are applied topically to the underarm or other suitable area of the skin to inhibit or prevent perspiration. The applied compositions form a discontinuous polymer-containing antiperspirant active on the applied skin surface, wherein the polymer-containing active is derived from water-reactive monomers that reacts with sweat at the opening of the sweat ducts after application, to thereby polymerize and form the polymer-containing antiperspirant active over and within the affected sweat ducts. The antiperspirant compositions and corresponding methods of application provide alternative antiperspirant active materials and product formulations, and provide improved efficacy and/or application cosmetics.

  • 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.

  • Patent number: 6139826
    Abstract: Disclosed are personal care compositions, especially hair styling compositions containing:(a) a graft copolymer characterized by having a hydrophilic organic polymeric backbone and hydrophobic macromonomers grafted to said backbone; the hydrophilic polymeric backbone having a Tg of at least about -20.degree. C.; the hydrophobic macromonomers having a carbon based main chain; a Tg of less than about 0.degree. C. and a number average molecular weight of at least about 500; and(b) a hydrophilic solvent preferably selected from the group consisting of water, C.sub.2 -C.sub.3 monohydric alcohols and mixtures thereof.
