  • Patent number: 4597887
    Abstract: An improved germicidal hard surface cleaning composition containing a quaternary ammonium germicide, detergent, builder salts and a binary solvent system comprising a saturated terpene hydrocarbon and a non-aqueous polar solvent is described. The binary system provides improved cleaning action for removal of greasy soil from porous and non-porous hard surfaces and does not interfere with the germicidal activity of the quaternary ammonium salt.

  • Patent number: 4526780
    Abstract: A novel stable anhydrous paste or cream composition having superior ultradry characteristics when applied to the skin comprising an antiperspirant or deodorant agent and an oil absorbent material homogeneously dispersed in a vehicle comprising about 25-55% of a volatile silicone and a clay suspending/thickening agent in the form of a gel, preferably a bentonite gel. Additionally preferable ingredients are stability agents to prevent syneresis (oil separation) such as the fatty acid metal salts, more specifically zinc, aluminum, calcium, magnesium, and lithium stearates. Additional thickeners, binders, suspending agents, emollients and nonionic emulsifiers may be added as desired to further enhance the aesthetics of the cream product. The resultant dry-feel cream products spread easily, are not wet, oily or sticky, and vanish almost immediately on rub-in when applied to the skin.

  • Patent number: 4439355
    Abstract: An elastic detergent product of improved form-retaining ability during elevated temperature storage and of improved foaming power after use comprises an organic detergent which is an ammonium or lower alkanolammonium anionic organic detergent salt or a mixture of such anionic detergent with amphoteric synthetic organic detergent, gelatin and a lower di- or polyhydric alcohol. The products made, which are essentially free of water, or anhydrous, and often are of bar, cake or shaped article forms, are of improved thermal stability, allowing them to be stored at higher temperatures than comparable products, without distortion, and do not readily form inhibiting gel structures or coatings after use, which could otherwise diminish foaming power. Also within the invention is a method of making the described detergent products.

  • Patent number: 4207198
    Abstract: An elastic detergent bar of improved form-retaining ability during elevated temperature storage and of improved foaming power after use comprises an organic detergent which is an ammonium or lower alkanolammonium anionic organic detergent salt or a mixture of such anionic detergent with amphoteric synthetic organic detergent, gelatin and a lower di- or polyhydric alcohol. The bars made, which are essentially free of water, are of improved thermal stability, allowing them to be stored at higher temperatures than comparable bars, without distortion, and do not readily form inhibiting gel structures or coatings after use, which could otherwise diminish foaming power. Also within the invention is a method of making the described detergent bars.

  • Patent number: 4154706
    Abstract: An all nonionic liquid shampoo which includes an amine oxide, a polyoxyethylene hexitan mono-higher fatty acid ester, and at least one of a higher alkoxy polyoxyethylene ethanol, an alkyl glycoside and a mixture of glycoside, a higher fatty acid lower alkanolamide and polyacrylamide. Optionally, the mixture of higher fatty acid lower alkanolamide and polyacrylamide may be present in the liquid shampoo containing amine oxide, polyoxyethylene hexitan mono-higher fatty acid ester and the higher alkoxy polyoxyethylene ethanol and/or alkyl glycoside. Another optional constituent is a polyethylene glycol higher fatty acid ester. The shampoos are essentially free of ions and are desirably completely free of ionic materials with the pH essentially neutral.

  • Patent number: 4112536
    Abstract: Apparatus for dispensing a fluent composition comprising a casing having a top opening with a stationary or rotatable arcuately surfaced web backing member projecting through the opening and a carrier web bearing the composition passes out of the casing through the opening at one side of the member to closely overlie the member and present a firmly backed convex applicator area outside said casing and then passes back into said casing along the other side of said member. In the preferred embodiments the used areas of the web are rewound within the casing, which may be disposable.

  • Patent number: 4088751
    Abstract: A packaged self-heating cosmetic, such as a shaving cream, hand lotion, depilatory, facial, or a shampoo, including separate exothermically reactive reductant material, such as 2-thio-4-oxypyrimidine or thiohydantoin or derivatives thereof, and an oxidant, which reacts with the reductant, generating heat. Means are provided for dispensing the packaged reductant and oxidant from separate zones and bringing them into contact with each other so that they react and heat a pressurized shaving cream or other cosmetic product whose constituents the exothermic reaction mixture contacts. The reducing agent employed is preferably 2-thio-4-oxypyrimidine or its tautomer, 2-mercapto-4-hydroxypyrimidine, or alkyl-substituted derivative thereof, and the oxidizing agent is preferably aqueous hydrogen peroxide.
