  • Patent number: 6383476
    Abstract: Disclosed are anhydrous antiperspirant and deodorant compositions that comprise from about 0.1% to about 30% by weight of an antiperspirant or deodorant active; from about 0.1% to about 20% by weight of a water-soluble, skin active solid (e.g., solid, water-soluble vitamins or other nutrients) other than the antiperspirant or deodorant active; from about 0.1% to about 40% by weight of a suspending agent; and from about 10% to about 99% by weight of an anhydrous carrier liquid, wherein the composition is substantially free of nonvolatile organic liquids having a C log P value greater than about 7.0. The anhydrous compositions allow the water-soluble skin active solids to release into the sweat or other moisture on the skin more rapidly or to a greater extent, thus enhancing any skin active effect resulting from such active materials contacting the skin, especially the underarm area of skin.

  • 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.

    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.

  • Patent number: 6149897
    Abstract: Disclosed is a process for making anhydrous compositions containing solubilized, enhanced antiperspirant active, which process comprises the steps of (A) heating an aqueous solution comprising from about 24% to about 55% by weight of a solubilized, non-enhanced, aluminum-containing antiperspirant active at a temperature of from 120.degree. C. to about 200.degree. C. for a period of time of from about 1 minute to about 15 minutes to form a solubilized, enhanced, aluminum-containing antiperspirant active; (B) adding an anhydrous solvent to the aluminum-containing solution at a weight ratio of the anhydrous solvent to the aluminum-containing antiperspirant actives of from about 1:2 to about 20:1; and C removing water from the anhydrous solvent-containing solution to form an anhydrous composition containing solubilized, enhanced, aluminum-containing, antiperspirant active. The process provides an improved method for making antiperspirant compositions containing solubilized, enhanced antiperspirant active.

  • Patent number: 6136303
    Abstract: Disclosed are anhydrous aerosol package compositions which comprise (a) a Lewis acid having a pKa of less than about 5.0; (b) from about 5% to about 95% by weight of a fluorinated hydrocarbon propellant; (c) a hydrogen bonded water source; and (d) a rust inhibition means. The aerosol package compositions are preferably anhydrous aerosol antiperspirants which comprise an antiperspirant active, a fluorinated hydrocarbon propellant such as 1,1-difluroethane, and a rust inhibition means, wherein the antiperspirant active acts as a Lewis acid and contains hydrogen bonded water. It was found that aerosol package compositions containing fluorinated hydrocarbons, a strong Lewis acid, and a hydrogen bonded water source are surprisingly susceptible to corrosion or rust formation of any metal surface within the package, unless a known or otherwise effective rust inhibition means is added to or used in association with the packaged aerosol composition.

  • Patent number: 6136302
    Abstract: Disclosed is a process for making zirconium-aluminum salts for use as antiperspirant active, which process comprises the step of anhydrous mixing of a zirconium salt and an aluminum salt to form a zirconium-aluminum salt, wherein the mixture of zirconium and aluminum salts is substantially free of unbound water at all times during the process. The zirconium, aluminum and zirconium-aluminum salts in the process are in the form of particulate or other solids, or can otherwise be dissolved or dispersed in a non-aqueous medium. The process allows for the formation of zirconium-aluminum salts as antiperspirant active without relying upon prior art methods which teach that zirconium-aluminum salts require reaction together in an aqueous medium. This process is more stable than the prior art methods and provides better control over optimizing the polymer size distribution within the resulting zirconium-aluminum salts.

  • Patent number: 6096296
    Abstract: A shaped crystalline deodorant is made from mixture of a mineral salt and water which is heated above the melting point of the salt, placed in a mold having the desired shape, and crystalized after insertion of an internally threaded member into the mixture. The deodorant has an oval cross-sectional shape with the insert imbedded therewithin and is secured into a container. The container includes a threaded stem attached to the container for rotational movement which is translated to axial movement of the deodorant with respect to the container. The threaded stem cooperates with the internally threaded insert to allow the crystallized deodorant to be moved up or down within the container by rotating the threaded stem.

  • Patent number: 6096297
    Abstract: An underarm composition is provided which includes C.sub.1 -C.sub.6 alkyl acetate, an underarm active selected from astringent salts and anti-microbial agents, and a carrier. The carrier may include propellant, silicone, ester and liquid paraffin. Methyl and t-butyl acetates are preferred. Acetates allow reduction in the levels of more volatile organics thereby decreasing air pollution. They also reduce formulation greasiness, are less clogging to spray nozzles, cause less metal can corrosion and reduce caking of actives through better resuspension.

  • Patent number: 6096298
    Abstract: The present invention is directed to deodorant compositions, and methods of using such compositions, wherein the compositions comprise from about 0.1% to about 99.9% by weight of a deodorant active, fragrance or combination thereof, and from about 0.1% to about 99.9% by weight of a carrier comprising isopropyl glycerol ether. The deodorant composition preferably further comprises a suitable gellant or structurant to provide the desired product form, including a deodorant gel solid stick. The isopropyl glycerol ether carrier is a highly effective coupling agent and is milder to the skin when applied topically to the axilla or other areas of the skin as compared to many other polyol-containing deodorant compositions. The present invention also relates to the use of triclosan/triclocarban combinations for improved deodorant efficacy.
