    摘要: Free-flowing and storable granular compacts containing ingredients of detergent or cleaning compositions in concentrated form are prepared by(1) preparing an adhesively bound dry premix containing(a) fine-particle detergent ingredients substantially free of binding or adhesive properties, and(b) fine-particle detergent ingredients having binding or adhesive properties, and optionally, detergent ingredients which are liquid at room temperature, to form a substantially homogeneous premix, and(2) press-molding the premix at a temperature of from about 40.degree. C. to 80.degree. C. in the substantial absence of shear forces whereby air is microdispersed in the resultant compacts.

    摘要: A process for producing stable, bifunctional, phosphate- and metasilicate-free, low-alkali detergent tablets useful for dishwashing machines from granulated detergent additives consisting of sodium salts of at least one homopolymeric or copolymeric (meth)acrylic acid, comprising agglomerating the granulated detergent additives with builders and water to form an agglomerate, treating the agglomerate with hot air in a fluidized bed, mixing the agglomerate with a bleaching agent, and tabletting the mixture.

    摘要: 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.
