Definitions

  • the present invention relates to pre-portioned multi-phase detergents, in particular automatic dishwashing detergents and their use.
  • Hard surface cleaners such as dishwashing detergents
  • dishwashing detergents are available to the consumer in a variety of forms.
  • traditional solid agents are gaining increasingly increasingly flowable and especially liquid to gel detergent in importance.
  • the consumer particularly appreciates the rapid solubility and the associated rapid availability of the ingredients in the cleaning liquor, especially in short-dishwashing programs and at low temperatures.
  • compositions in which in particular the water content is reduced compared to conventional compositions, increases.
  • compositions whose water content is as low as possible are particularly desirable.
  • Disposable portions in particular water-soluble bags or multi-chamber tablets made of water-soluble material, enjoy the consumer not only because of increasing popularity, because the consumer with the chemical composition is no longer in contact, but not least because of the attractive appearance of the bag. For the consumer, it is therefore a nuisance if the bags lose their attractive appearance.
  • Multifunctional automatic dishwashing detergents save the user the separate use of rinse aid and the refilling of salt in the dishwasher.
  • certain builders are used in their formulations which achieve a good rinse aid result and counteract the formation of coatings even at higher water hardness.
  • Modern dishwashers provide for dosing of cleaning products before a dosing, which automatically opens during the wash program and releases the product.
  • the size of the metering chamber is however limited in its capacity. For a good cleaning performance, however, sufficient quantities of various functional blocks of the dishwashing detergent formulation, such as builder, alkalinity, enzymes, surfactants, etc., must be made available. This means that the available volume of the dosing chamber must be used optimally in order to produce a sufficient amount of the active substances and thus a good cleaning performance.
  • the object of the present invention was to provide a multi-phase pre-portioned detergent, in particular dishwashing detergent, preferably automatic dishwashing detergent, with at least one liquid and at least one solid, preferably pulverulent phase, which fits into the dispensing compartment of the dishwasher and still exhibits good cleaning performance.

  • co-builders In particular in cleaning agents, in particular in those which contain only small amounts of phosphate or which are substantially free of phosphates, co-builders must be used in addition to the phosphate-containing and / or phosphate-free builders in order to achieve a sufficiently high complexation of divalent cations from the used Rinse water, usually local tap water to ensure that otherwise leave on the dishes coverings.
  • Polymeric, polycarboxylate-containing cobuilders are usually marketed as aqueous preparations. In aqueous machine dishwashing detergents, they are therefore usually formulated directly into the aqueous cleaning agents. If they are to be used in solid formulations, they must first be dried time-consuming and energy-intensive and then formulated as granules. Then they are particularly suitable for solid, especially granular products.
  • aqueous preparations of co-builders are not suitable due to the high water input.
  • a space-saving formulation In a multi-phase pre-portioned detergent, in particular machine dishwashing detergent, which contains at least one solid and one liquid phase, which is optimized in terms of the dimensions of the metering chamber in dishwashers, a space-saving formulation must be used in particular.
