Definitions

  • the present invention relates to a process for the preparation of formulations according to the invention and their use as or for the production of dishwashing agents, in particular dishwasher detergents for automatic dishwashing.
  • Dishwashing detergents have many requirements to fulfill. So they have to clean the dishes thoroughly, they should have no harmful or potentially harmful substances in the wastewater, they should allow the draining and drying of the water from the dishes, and they should not cause problems when operating the dishwasher. Finally, they should not lead to aesthetically undesirable consequences on the good to be cleaned. Especially in this context is the glass corrosion.
  • Glass corrosion is caused not only by mechanical effects, for example by rubbing glasses or mechanical contact of the glasses with parts of the dishwasher, but is mainly promoted by chemical influences.
  • certain ions can be released from the glass by repeated mechanical cleaning, adversely altering the optical and thus the aesthetic properties.
  • Glass corrosion has several effects. On the one hand, one can observe the formation of microscopically fine cracks, which are noticeable in the form of lines. On the other hand, one can often observe a general cloudiness, for example a roughening, which makes the glass in question look unaesthetic. Overall, such effects are also subdivided into iridescent discoloration, scoring and surface and annular opacities.
  • WO 2006/108857 discloses alkoxylated polyethyleneimines as additives to detergents.
  • Detergents containing zeolites or polyaminocarboxylates such as EDTA or triethylenediamine pentaacetate as complexing agents are disclosed by way of example.

  • WO 2009/062699 discloses dishwashing compositions containing MGDA or IDS as complexing agent and percarbonate as bleaching agent.
  • Dishwashing agents which contain polyethyleneimine. Such dishwashing agents may contain phosphate or be phosphate-free. It is attributed to them a good inhibition of glass corrosion.
