Patent number: 6136303Abstract: 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.Type: GrantFiled: March 10, 2000Date of Patent: October 24, 2000Assignee: The Procter & Gamble CompanyInventors: Nicholas Arthur Ruebusch, Scott Edward Smith, David Frederick Swaile

Patent number: 6136302Abstract: 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.Type: GrantFiled: February 18, 1999Date of Patent: October 24, 2000Assignee: The Procter & Gamble CompanyInventors: Prem Sagar Juneja, David Frederick Swaile

Patent number: 6126927Abstract: A method of making an antiperspirant powder is provided, including mixing a silicone rubber powder solution with an antiperspirant salt in a liquid carrier to form a uniform liquid mixture; and drying the liquid mixture to form an antiperspirant powder.Type: GrantFiled: June 19, 1998Date of Patent: October 3, 2000Assignee: The Gillette CompanyInventors: Stephen Provancal, Richard Oryszczak, Philip P. Angelone, Jr., Nancy M. Karassik

Patent number: 6113891Abstract: There are disclosed stable fluidized polymer suspensions containing cationic polysaccharide, stabilizing agent and emollient. The preferred cationic polysaccharides are cationic guar and cationic hydroxypropyl guar, and preferred emollients are hydrocarbons, silicone oils and esters. Processes for preparing personal care compositions utilizing the fluidized polymer suspensions are also disclosed. Using the fluidized polymer suspensions in the processes provides the advantages of more rapid dissolution and avoidance of lumps and gels when compared to using dry, powdered cationic polysaccharides.Type: GrantFiled: November 20, 1998Date of Patent: September 5, 2000Assignee: Hercules IncorporatedInventors: Charles Lee Burdick, Jacobus Johannes deBruin, Hans Hofman, Mohand Melbouci

Patent number: 6096296Abstract: 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.Type: GrantFiled: October 24, 1997Date of Patent: August 1, 2000Inventors: Theodore Alflen, William Miller

Patent number: 6096297Abstract: 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.Type: GrantFiled: January 12, 1999Date of Patent: August 1, 2000Assignee: Unilever Home & Personal Care USAInventors: Francis Jones, David Allen Brewster

Patent number: 6096298Abstract: 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.Type: GrantFiled: August 24, 1999Date of Patent: August 1, 2000Assignee: The Procter & Gamble CompanyInventor: David Frederick Swaile
