  • Suitable water-soluble films are sold, for example, by MonoSol LLC under the designation M8630, M8720, M8310, C8400 or M8900.
  • Other suitable films include films with the label Solublon ® PT, Solublon ® GA, Solublon KC ® or Solublon ® KL by Aicello Chemical Europe GmbH, or VF-HP film available from Kuraray.
  • the water-soluble films can contain additional active substances or fillers, but also plasticizers and/or solvents, in particular water, as further ingredients.
  • the group of further active ingredients includes, for example, materials which protect the ingredients of preparation (A) enclosed by the film material from decomposition or deactivation by exposure to light.
  • Antioxidants, UV absorbers and fluorescent dyes have proven to be particularly suitable here.
  • glycerol ethylene glycol, diethylene glycol, propanediol, 2-methyl-1,3-propanediol, sorbitol or mixtures thereof can be used as plasticizers.
  • the surface of the water-soluble film can optionally be powdered with fine powder.
  • Sodium aluminosilicate, silica, talc and amylose are examples of suitable powdering agents.
  • the detergent portion unit has a plurality of receiving chambers.
  • the several receiving chambers of the detergent portion unit can be arranged spatially next to one another or one above the other (stacked). These technical advantages are particularly obvious in the case of detergent portion units with receiving chambers which at least partially enclose one another.
  • the detergent portion unit has at least two receiving chambers, one receiving chamber being at least partially surrounded by at least one further receiving chamber. It is also very particularly preferred if the detergent portion unit has at least one further receiving chamber which is filled with a colored detergent preparation.
  • a detergent portion unit preferred according to the invention has at least two receiving chambers which are surrounded by a water-soluble film, one receiving chamber being filled with the free-flowing detergent preparation and the other receiving chamber being filled with a second colored detergent preparation different from the free-flowing detergent preparation.
  • Another exemplary preferred detergent portion unit comprises at least three receiving chambers, which are surrounded by a water-soluble film, one receiving chamber being filled with the free-flowing detergent preparation and at least two other receiving chambers being filled separately from one another with a second and a third colored detergent preparation that are different from one another and from the free-flowing detergent preparation are.
  • the detergent portion unit has at least four receiving chambers, which are surrounded by a water-soluble film, with one receiving chamber being filled with the free-flowing detergent preparation and the other three receiving chambers being separated from one another with a second and a third and a fourth from one another and from the free-flowing detergent preparation different colored detergent preparations are filled.
  • a second subject of this application is a method for cleaning textiles, in which a previously described free-flowing detergent preparation or a previously described detergent portion unit is introduced into the wash liquor of a textile washing machine.
  • the starting point of the method according to the invention is the provision of a first free-flowing detergent preparation containing surfactant, fatty acid and solvent.
  • the preparation of this preparation can be carried out in advance in a continuous or discontinuous manner.
  • a line system preferably provided with mixing devices, in which the components of the preparation are brought into contact with one another and mixed, is suitable for continuous production. Due to the reduced outlay in terms of equipment and operations, however, it is preferred if the first free-flowing detergent preparation is provided discontinuously.
  • providing the preparation as a storable mixture (master batch) in a stirred tank or some other container is suitable for this.
  • Such a container not only enables the storage of intermediate products, but also makes it possible to buffer any fluctuations in the throughput rates of the subsequent process steps, which are preferably carried out continuously. It is therefore also preferred if the first free-flowing detergent preparation is introduced continuously from a buffer container into a main line.
  • the salt of a divalent cation is introduced into the liquid composition. This is preferably done via a secondary line, through which the salt is continuously introduced into the main line. In order to simplify the procedure, it is preferred if the salt of a divalent cation is introduced into the main line via a secondary line in the form of a carrier liquid-particle dispersion.
  • the addition of the salt of a divalent cation results in the formation of a cloudy white appearance and a sufficiently high and stable viscosity, which is advantageous for the further course of the process and subsequent use.
  • the development of both physical properties of the liquid composition is promoted by mixing all the ingredients. It is therefore also preferred to provide the outlet opening of the secondary line, through which the salt of a divalent cation is introduced into the main line via a secondary line, in the effective area of a mixing device which is mounted within the main line.
  • the mixing device can be a static or a dynamic mixer.
  • the resulting metal salt-containing composition can subsequently be expanded or differentiated by adding further active substances.
  • the addition of an active substance from the group of optionally encapsulated fragrances, enzymes, preservatives, bitter substances, preferably from the group of optionally encapsulated fragrances, enzymes and preservatives, is particularly suitable for this purpose, which is preferably carried out after the Introduction of the salt of a divalent cation, is introduced into the main line via a side line. It is particularly preferred, after the introduction of the salt of a divalent cation, to introduce an active substance from the group of fragrances or enzymes into the main line via a secondary line.
  • the additional active can be added to the composition before mixing the salt and colorant-containing composition or after this step.
  • the further active substance is introduced after the mixing of the salt- and colorant-containing composition.
  • a further mixing step which follows the introduction of the active substance.
  • the use of static mixers is particularly suitable for this mixing step.
