Abstract: High-viscosity liquid detergents which, as a result of using a thickening system, are storage- and viscosity-stable under very diverse climatic conditions, do not undergo phase separation, and have color stability when exposed to light.

Abstract: The invention relates to the use of mutated protease of the subtilisin type which carries at least one mutation in its amino acid sequence, leading to a reduced positive charge or an increased negative charge in the substrate binding region of the molecule, in liquid to gel-form laundry detergents. This protease shows increased stability above all in detergents such as these.

Abstract: The crude reaction products from the synthesis of alkyl glycosides are bleached by kneading the material substantially freed from the excess fatty alcohol and containing at most limited quantities of water with an oxidizing agent at such elevated temperatures that the reaction mixture lends itself to plastic processing. Temperatures of from about 50.degree. to 150.degree. C. are particularly suitable, although it is best to apply temperatures in the range from about 80.degree. to 100.degree. C. using aqueous hydrogen peroxide as the oxidizing agent. Bleaching is carried out under basic conditions, optionally by addition of an alkaline compound, such as for example 50% sodium hydroxide solution. The bleached product accumulates in the form of a solid. It is preferably mixed with typical compatible solids, more particularly typical constituents of detergents and cleaning preparations, to form a solid and preferably free-flowing alkyl glycoside compound.

Abstract: Powder-form preparations of surface-active alkyl glycosides contain 5 to 65% by weight of a surface-active alkyl glycoside and 35 to 95% by weight of an inert inorganic support. They are produced by mixing the crude product obtained in the industrial production of the alkyl glycosides with water and an inorganic particulate support, for example silica, chalk or sodium chloride, and drying the resulting mixture. Preferred powder-form preparations contain 20 to 50% by weight of the alkyl glycoside and 50 to 80% by weight of an inert inorganic support.
