  • Water-soluble colloids of mostly organic nature are suitable for this purpose, for example the water-soluble salts of polymeric carboxylic acids, glue, gelatin, salts of ether carboxylic acids or ether sulfonic acids of starch or of cellulose or salts of acidic sulfuric acid esters of cellulose or starch.
  • water-soluble polyamides containing acidic groups are suitable for this purpose.
  • particulate compositions according to the invention can be carried out in the simplest manner by mixing the individual particles in a conventional mixer, in particular a drum, roller, belt or free-fall mixer, whereby optional other pulverulent constituents and, if desired, also liquid or liquefied constituents, to which in particular nonionic surfactants , but also colorants and fragrances may be added by spraying. It is preferred to convert the thermally loadable components in a manner known in principle by spray-drying an aqueous slurry into a particulate product and, if appropriate, to mix this with thermally sensitive constituents, to which in particular the bleaching agents are to be expected.
  • a conventional mixer in particular a drum, roller, belt or free-fall mixer
  • Granular high-density detergents according to the invention may preferably be prepared according to the method of International Patent Application WO 91/02047 getting produced. This is the strand-like compression of a homogeneous premix of detergent ingredients via hole-forming, which preferably have an opening width of 0.5 mm to 5 mm, followed by comminuting the extrudate and subsequent treatment in a Rondier réelle, which leads to substantially uniformly spherical products. Granular particles having bulk densities of generally 700 g / l to 1050 g / l are obtained by the compacting extrusion step. These may be complete washing or cleaning agents or components of such agents, which are completed by admixing usually not co-extrudable further components, such as solid or formulated foam regulators or enzymes in solid form.
  • a powdered detergent ( BW ) of the composition given in Table 1 below was used alone and after addition of 1.2% by weight of polyvinylpyrrolidone having an average molar mass of about 40,000 ( V1 ), 8% by weight perborate monohydrate and 2 %
