Definitions

  • the present invention relates to a Dishwasher detergent in the form of a tablet containing a bleach and a bleach activator and other common ingredients.
  • Tablet detergent compositions deteriorated cleaning effect compared to those in Can have powder form. This can be attributed to this be that the individual in compressed tablets Components are much closer together than in powders, so that negative interactions, the individual Exercise components on each other, occur more can. This can lead to partial inactivation individual components come.
  • Dishwasher detergent occurs in tablet form and the washing performance deteriorates is that such Dishwasher detergents are less effective than comparable powder since the tablets dissolve more slowly and therefore in the wash liquor only later than in the Use of powders are available.
  • This problem occurs particularly in dishwashing detergents, which contain a bleaching agent, since when such Tablet means one necessary for bleaching Bleach concentration is relatively late during the Rinsing process is reached.
  • EP-A 504 091 Solution to this problem suggested a certain one Combination of alkali carbonate, polycarboxylate, one polyfunctional carboxylic acid, sodium silicate, one use nonionic surfactant and the bleach, so the bleaching effect is obtained with compressed tablets remains.
