Zinc Compound Containing Patents (Class 424/67)
  • 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: 6245324
    Abstract: A particulate antiperspirant active material which has been surface treated with an alkanolamine is described. After surface treatment, the surface treatment agent is in intimate contact with the surface or outer layer of the substrate material, that is, the antiperspirant material may be either deposited on the surface or at least a fraction of the agent may be absorbed within the outer layer of the substrate. The resultant particulate material shows a reduced tendency to separate from a liquid carrier phase containing a polyglycol ether and a suspending agent.

  • Patent number: 5911975
    Abstract: Disclosed is a cosmetic composition (solid or liquid, for example, including sticks and gels) containing an antiperspirant active aluminum-containing material, such as aluminum chlorohydrate, in a solvent therefor, and also containing poly(ethenylformamide) as a thickening agent of the composition. This composition can be an antiperspirant composition, where it contains an antiperspirant effective amount of the antiperspirant active aluminum-containing material, and can be applied to axillary regions of a human to reduce perspiration therefrom. Ammonium acetate can also be incorporated in the composition, to firm up the composition. The composition can be in the form of a gel, dispensed by extruding the gel through pores or slots in the top of a dispensing container. The composition can be clear and transparent, without the need of refractive index matching to achieve clarity.
