Patent number: 5431840Abstract: In the new process, cleaning and care preparations for floors, shoes, leather and furniture are produced by mixing a wax emulsion containing alkyl glycoside as emulsifier with the other constituents of the preparation. The alkyl glycosides correspond to the following general formulaR--O(--G).sub.n Iin which R is a long-chain C.sub.8-22 alkyl radical, G is a glycoside-bonded residue of a monosaccharide and n has a value of 1 to 10. The wax emulsions are distinguished by particular particle fineness and extremely good compatibility with the other constituents of the preparations.Type: GrantFiled: June 21, 1993Date of Patent: July 11, 1995Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Heinz-Dieter Soldanski, Bernd-Dieter Holdt, Juergen Noglich

Patent number: 5356479Abstract: Bathroom fittings and other hard surfaces are cleaned with a foam containing an alkyl polyglycoside as the principal surfactant. An effective amount of the foam is applied to a surface and removed by wiping with a cloth, sponge, or paper towel or by rinsing with water. Any residual foam remaining on the surface is not detectable by the naked eye because the residual material is transparent.Type: GrantFiled: August 24, 1992Date of Patent: October 18, 1994Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Ronald Menke, Bernd-Dieter Holdt, Petra Plantikow

Patent number: 4834900Abstract: A process for the removal of stains from fabrics, such as carpets. The process comprises treating the stained areas of the fabrics with a liquid, paste-form or foam-form stain remover and subjecting the entire fabric to cleaning with a powder-form cleaning composition before the treated areas have dried. The preferred stain remover is an aqueous composition containing a surfactant, and the preferred powder-form cleaning composition contains a finely divided cellulose powder as an adsorbent. The new process is suitable above all for the cleaning of carpets and carpeted floors.Type: GrantFiled: March 7, 1988Date of Patent: May 30, 1989Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Heinz Soldanski, Bernd-Dieter Holdt, Petra Keup, Ursula Meier-Krug

Patent number: 4813084Abstract: In a cleaning system for toilet bowls comprising a cleaning container for accommodating a cleaning preparation which is designed to be mounted on the rim of the toilet bowl and which is provided with correspondingly arranged openings for part of the flushing water to pass through, the invention enables the cleaning container to be filled with granular active substance without spillage and/or granulate to come into contact with the skin. In addition, the cleaning container is designed so that in the in-use position, its contents are substantially inaccessible to young children despite the refill facility.Type: GrantFiled: November 20, 1987Date of Patent: March 21, 1989Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Herbert Buecheler, Thomas Capune, Bernd-Dieter Holdt, Ronald Menke, Erich Tuerk
