  • washing or cleaning agent disposable portions according to the invention are characterized in that the wrapping is a film packaging shrunk onto the latter.
  • this wrapping can be done by placing a water-soluble lower film on a conveyor chain or a mold (s) tool, then one or more detergent or cleaning agent portion (s) are placed on the lower film; then a water-soluble upper film is placed on the washing or cleaning agent portion (s) on the lower film and this is then fixed on the lower film, including the washing or cleaning agent portion (s),
  • this step can also be done by a single-stranded film, which is then placed around the disposable portions as a tube. This is followed by sealing and optional cutting of the films. Subsequently, then the shrinking of the film by the use of hot air or infrared radiation, optionally with pressing done.
  • Exemplary formulations of the agents according to the invention also include, in particular, phosphate-free dishwashing detergents.
  • An exemplary formulation in which those described herein Polymers in the indicated amounts can be used as an additional constituent, is the following:
  • the corresponding use of the automatic dishwasher detergents according to the invention is likewise an object of the invention.
  • the invention likewise relates to a dishwashing process, in particular a machine dishwashing process, in which a dishwashing detergent according to the invention is used.
  • the subject matter of the present application is therefore furthermore a process for the cleaning of dishes in a dishwashing machine, in which the agent according to the invention is passed into the interior of a dishwasher during the passage of a dishwashing program before the main wash cycle or during the main wash cycle
  • Dishwasher is metered.
  • the metering or the entry of the invention Means into the interior of the dishwasher can be done manually, but preferably the agent is metered by means of the metering chamber into the interior of the dishwasher.
  • Nonionic surfactants 5.1 5.1
  • Nonionic surfactants 1, 5 1, 5 are nonionic surfactants 1, 5 1, 5
  • Nonionic surfactant 0,2 0,2
  • the cleaning performance was determined in Miele GSL dishwashers in the 45 ° C program. Water hardness 21 ° dH. For this purpose, 20 g of the above formulations (tab) were used. After completion of the rinse cycle, the dishes were visually peeled off on a scale of 1-10. The higher the value, the better the cleaning performance. It can be seen that the formulation E1 according to the invention, which contains MGDA in the bleach phase, shows a better cleaning performance on enzyme-sensitive soils, such as minced meat, compared to the comparison formulation V1, which contains MGDA in the enzyme phase (Table 2).
