Zirconium Compound Containing Patents (Class 424/66)
  • Patent number: 6488919
    Abstract: Semi-solid antiperspirant compositions are disclosed. These compositions do not leave a significant white residue on the skin of the user and exhibit good skin feel when applied. In addition, the compositions allow for the incorporation of free water into the formulation without deactivating the antiperspirant active. This is particularly useful in the incorporation of solutions of natural botanical components into the antiperspirant composition. The semi-solid antiperspirant compositions of the present invention comprise from about 5% to about 35% of a particulate antiperspirant active; from about 10% to about 60% of a volatile solvent; from about 2% to about 15% of a thickening agent; from about 1% to about 10% of an ester wax; and from about 0.5% to about 10% water.

  • Patent number: 6361766
    Abstract: Anhydrous antiperspirant formulations in which a particulate antiperspirant active is suspended in a carrier fluid can result in significant visible deposits when applied to skin or when transferred onto clothing. Anhydrous antiperspirant suspension sticks which exhibit very low visible deposits are obtainable by employing a carrier fluid in which at least 45% and preferably at least 60% of its weight comprises an oxygen-containing emollient oil having a refractive index of at least 1.465, in conjunction with structurant comprises a wax or a non-polymeric fiber-forming gellant, excluding certain gellants or gellant combinations. Preferred emollient oils include alkyl benzoates and alkylphenylsiloxanes. The waxes can even comprise fatty alcohols.

  • Patent number: 6342210
    Abstract: A method for forming micronized antiperspirant salts is disclosed wherein the method comprises the steps of: (1) forming an aqueous salt solution of a parent salt wherein the solution has a glycol content of less than 5 weight %; (2) pouring the salt solution onto a bounded flat surface; (3) evaporating the solvent from the salt solution so as to form a glass; (4) breaking up the glass using one or more steps to form particles having an average size in the range of 0.5-2.00 cm2; (5) mixing the particles from step (4) with a non-aqueous liquid vehicle in which the salt is not appreciably soluble and subjecting the mixture to an intermediate grinding process to form a suspension with particles having an average size of less than 200 microns; and (6) grinding the mixture from step (5) at a temperature in the range of 20-70 degrees C. without added water or external heating being required so that the particles in the suspension have an average particle size of less than or equal to 20 microns.

  • Publication number: 20010055574
    Abstract: A cosmetic composition is a structured emulsion of a continuous phase containing water-immiscible liquid carrier plus a structurant, and a disperse phase which is a solution of antiperspirant active in a more polar, probably aqueous, solvent. The structurant is a material which forms a network of fibers in the continuous phase, thereby gelling it. The structurant has an enthalpy of gelation in the carrier liquid or a test liquid with a magnitude of at least 30 kJ/mole. This minimum enthalpy of gelation facilitates processing at conveniently accessible temperatures and promotes stability.

  • 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: 6261543
    Abstract: Antiperspirant emulsions which exhibit excellent phase stability even in the presence of an effective concentration of antiperspirant salts in solution and which are thickened are obtainable by dispersing a hydratable polymer and particularly an amphoteric or cationic modified starch in an aqueous emulsion forming a viscous emulsion, often at an elevated temperature, subjecting the emulsion to high shear, thereby reducing the droplet size of the dispersed oil phase, bringing the emulsion to below 40° C. and introducing the antiperspirant, preferably in aqueous solution. The viscous emulsion subjected to high shear mixing desirably has a Sheer Stress of 10 to 500 Pa. The resultant emulsions show good phase stability even when they contain aluminium/ zirconium antiperspirant salts that promote instability and even at elevated storage temperatures such as at 50° C.
