- an agent according to the invention can contain graying inhibitors.
- Graying inhibitors have the task of keeping the dirt detached from the fiber suspended in the liquor and thus preventing graying of the fibers.
- 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 cellulose or salts of acidic sulfuric acid esters of cellulose or starch.
- Water-soluble polyamides containing acidic groups are also suitable for this purpose.
- liquid agents according to the invention presents no problems and can be done by simply mixing their ingredients.
- Particulate compositions according to the invention can be produced in the simplest way by mixing the individual particles in a conventional mixer, in particular a drum, roller, belt or free-fall mixer, optional other powdery components and, if desired, also liquid or liquefied components, in particular non-ionic surfactants, but also colorants and fragrances, which can be mixed in by spraying. It is preferred to convert the thermally resilient components into a particulate product in a manner known in principle by spray drying an aqueous slurry and, if appropriate, to mix this with thermally sensitive components, which in particular include the bleaching agents.
- Known extrusion and / or garnishing processes can also be used to produce particulate compositions according to the invention or their partial products.
- Granular detergents according to the invention with a high bulk density can preferably be prepared according to the method of international patent application WO 91/02047. This involves the extrusion of a homogeneous premix of detergent ingredients over perforated shapes, which preferably have an opening width of 0.5 mm to 5 mm, subsequent comminution of the extrudate and subsequent treatment in a rounding device, which results in largely uniform spherical shapes Products.
- the compacting extrusion step gives granular particles with bulk densities of generally 700 g / 1 to 1050 g / 1.
- These can be complete detergents or cleaning agents or constituents of such agents, which are added by admixing other components which are usually not co-extrudable, for example solid or solid foam regulators or enzymes. Examples
- a powder detergent (BW) with the composition given in Table 1 below was added alone and after adding 1.2% by weight of polyvinylpyrrolidone with an average molar mass of approximately 40,000 (VI), 8% by weight of perborate monohydrate and 2 %
- TAED 0.2% by weight of polyvinylpyrrolidone and 8% by weight of perborate monohydrate (MI) and 1.2% by weight of polyvinylpyrrolidone, 8% by weight of perborate monohydrate and 2% by weight of TAED (M2) tested for the ability to prevent "bleeding" (transfer of textile color from dyed textile to white textile when washing together).
- the agents (MI and N2) according to the invention have significantly better ink transfer inhibition performance than the agents which do not contain the combination of bleaching agent and polyvinylpyrrolidone.
