  • Other additives include, for example, release aids, fillers, crosslinking agents, surfactants, antioxidants, UV absorbers, antiblocking agents, anti-adhesive agents or mixtures thereof.
  • Suitable water-soluble films for use in the water-soluble wrappings of the water-soluble packaging according to the invention are films which are sold by MonoSol LLC, for example under the name M8630, C8400 or M8900.
  • Other suitable films include films with the designation Solublon® PT, Solublon® GA, Solublon® KC or Solublon® KL from Aicello Chemical Europe GmbH or the films VF-HP from Kuraray.
  • the multi-phase dishwashing detergent is closely enveloped by a water-soluble film
  • the water-soluble film which is preferably used in the narrow wrapping, particularly preferably comprises polyvinyl alcohol, as described above, the starting thickness preferably being from 10 ⁇ m to 100 ⁇ m, in particular from 12 ⁇ m to 60 ⁇ m, particularly preferably from 15 ⁇ m to 50 ⁇ m, especially from 20 ⁇ m to 40 ⁇ m, in particular from 22 ⁇ m to 35 ⁇ m is used.
  • the mechanism described here will not work if the casing is not snug, since the tablet can swell without the casing being blown up.
  • the use of a swellable disintegration agent is superior to a gas-generating system, since its explosive effect in any case leads to the casing being torn open. In a gas-generating system, the explosive effect can "dissipate" by the gas escaping from a leak in the casing.
  • Preferred detergent or cleaning agent disposable portions according to the invention are characterized in that the distance between the single portion and water-soluble coating over the entire area is 0.1 to 1000 ⁇ m, preferably 0.5 to 500 ⁇ m, particularly preferably 1 to 250 ⁇ m and in particular 2.5 to 100 ⁇ m.
  • the film covering is first loosely placed around a single detergent or cleaning agent portion and welded and then shrunk onto it, so that there is close contact between the film packaging and the cleaning agent concentrate.
  • disposable detergent or cleaning agent portions according to the invention are characterized in that the wrapper is a film packaging shrunk onto it.
  • this wrapping can be carried out by placing a water-soluble bottom film on a transport chain or a mold (s), then placing one or more detergent or cleaning agent portions (s) on the bottom film; then a water-soluble top film is placed on the detergent or cleaning agent portion (s) on the bottom film and this is then fixed on the bottom film, including the detergent or cleaning agent portion (s),
  • this step can also be carried out using a single-strand film, which is then placed around the one-time portions as a tube.
  • the foils are then sealed and optionally cut.
  • the film can then be shrink-wrapped using hot air or infrared radiation, optionally with pressure.
  • Exemplary formulations of the agents according to the invention in particular also include phosphate-free dishwashing agents.
  • An exemplary recipe in which those described herein Polymers can be used as additional components in the specified amounts the following is: Phosphate-free, solid dishwashing detergent formulation (tab): raw material Quantity (% by weight) Na citrate 15.00-20.00 Phosphonate (e.g.
  • the corresponding use of the automatic dishwashing agents according to the invention is also an object of the invention.
  • the invention also relates to a dishwashing method, in particular machine dishwashing method, in which a dishwashing agent according to the invention is used.
  • the subject of the present application is therefore also a method for cleaning dishes in a dishwasher, in which the agent according to the invention is metered into the interior of a dishwasher during the course of a dishwasher program before the start of the main wash cycle or in the course of the main wash cycle.
  • the metering or entry of the invention By means of the interior of the dishwasher can be done manually, but the agent is preferably dosed into the interior of the dishwasher by means of the dosing chamber.
  • the cleaning performance was determined in Miele GSL dishwashers in the 45 ° C program. Water hardness 21 ° dH. For this, 20 g of the above recipes (tab) were used. At the end of the wash cycle, the dishes were visually checked 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 bleaching phase, shows a better cleaning performance on enzyme-sensitive soiling, such as minced meat, compared to the comparison formulation V1, which contains MGDA in the enzyme phase (Table 2). Table 2: Cleaning performance ADW product (fresh) Minced meat E1 6.3 V1 5.9 ADW product After 1 week storage at 40 ° C E1 6.6 V1 5.9
