  • the method according to the invention will / become one or more detergent, detergent or dishwashing active preparation (s) in surrounding, preferably concentric or coaxial with each other Compartments filled or arranged in the form concentric or coaxial with each other or partially or completely surrounding compartments.
  • These will, optionally together with one or more washing active, cleaning active or rinse-active preparation (s), in a separately prepared dimensionally stable shaped body brought in.
  • the partially or completely surrounding each other Compartments, preferably arranged concentrically or coaxially to each other Compartments, in addition to one or more others, with one or more in the detergent-containing or rinse-active preparation (s) filled compartment (s) in the dimensionally stable hollow body are present or contained alone in this.
  • one or more washing-active, detergent-active or rinse-active preparation in a compartment-containing or in Formally stable hollow bodies containing distributed over several compartments closed and so the Preparation (s) sealed inside.
  • This can - as already described above - by Applying a "lid" on the still open (n-th) surface of the dimensionally stable hollow body or -
  • For spherical or elliptical hollow bodies by applying a corresponding partial spherical shell or partial ellipse shell done on the opening.
  • the application can preferably by way of bonding, preferably with a water-soluble adhesive, fusing, welding or otherwise, to a person skilled in the art Known ways of connecting done.
  • the water solubility of the walls / compartments surrounding the phases can be set so that every 5 to 10 minutes after opening a compartment pass until the contents of the next compartment are released.
  • Simplified forms of detergent portion can be prepared by the Phase 2 is omitted and their contents on the phases 1 (protease) and 3 (soda, Alkali carrier) is distributed, and that in a further simplification in addition to the phase 2 and the Phase 4 is omitted, perfume, optical brightener and Phase 3 Soil Repellent be slammed and the fabric softener is dosed in a separate product.
  • the detergent, detergent or detergent portions according to the invention are solved in an advantageous manner the tasks. So can be incompatible wash-active, cleaning-active or rinse-active preparations or their components spatially separate and can not due to the lack of a common contact area React reactions with each other, in particular no activity of the respective preparation debilitating reaction. This leads - especially at elevated drug concentrations - to an increased storage stability of the detergent, detergent or detergent portions, to an improved washing performance due to the lack of activity loss and to Saving of active substance, since earlier due to the expected loss of activity to be used excess of active substance in the detergent, detergent or Detergent portions according to the invention can be omitted.
  • the in the hollow bodies with one or several compartments contained detergent, makesmittek- or detergent portions promise a consistent and pre-packaged dosage with all for the entire washing, cleaning or rinsing required or desired Components.
  • the dosage is done in one step, and the solubility of the enclosure or the hollow body material to release the Ingredients are reliable according to predetermined or predetermined kinetics, so that the Clearly improve washing, cleaning or rinsing results compared to powdered ones Means or compressed moldings of the same composition without compartmentalized Separation of the components.
  • Example 1 Polyvinyl alcohol granules (Vinex® 2019 from the company Texas Polymers) were used on a hydraulic Screw injection molding machine of the company Arburg melted and in simple tools with Hot runner nozzle injected.
  • Example 2 a trochoidal shell with three corrugated Partitions and a peripheral edge made in Example 2 a hemisphere with a circumferential stacking approach and a border.
  • the mold shells prepared in the manner described above were introduced into water and measured time to disintegration or to complete dissolution: Temperature [° C] 20 30 40 50 60 Decay after [min] 12 7 5 4 2 complete resolution after [min] 18 11 8th 6 4
  • Polyvinyl alcohol granules (Vinex® 2019 from the company Texas Polymers) were used on a hydraulic Screw injection molding machine of the company Arburg melted and in simple tools with Hot runner nozzle injected, wherein the shell is in the form of a hemisphere with a circumferential Stacking neck and a border showed.
  • a half-shell was treated with a low-water commercial liquid detergent (Persil® Gel, commercial product of the Applicant) and filled with a polyvinyl alcohol film of the company Greensol closed.
  • a second half-shell was made with an extruded, bleach-containing Heavy duty detergent (Persil® Megaperls®, commercial product of the Applicant) filled and also plugged with a PVAI film.
