Definitions

  • the present invention relates to mixtures of surface-active substances for use in cleaning agents and in particular in dishwashing detergents for automatic dishwashing.
  • the cleaning of hard surfaces and especially the washing of dishes makes special demands on the cleaner used. This applies in particular to automatic dishwashing.
  • the three components of the machine system are cleaner, rinse aid and regenerating salt.
  • the central tasks of the main component cleaners are the soil release, the dirt dispersion, the binding of residual water hardness and the corrosion inhibition.
  • Conventional multifunctional automatic dishwashing detergents (so-called "ADD" automatic dish detergents) have a much poorer drying performance compared to the conventional rinse aid system (detergent, salt and rinse aid as separate products). Drying performance is to be understood in how far a dishwashing item which has been cleaned with a dishwashing detergent still has water, preferably water droplets, on the surface after passing through the dishwashing process.
  • the EP 1 306 423 A2 discloses aqueous detergents which contain alkyl ether sulfates and amphoteric glycine compounds and are suitable for improving the drying behavior of dishwashing detergents.
  • the DE 100 45 289 A1 describes hand dishwashing detergents which contain certain quaternary ammonium compounds and alkyl ether sulfates side by side and also show a particularly good drying behavior.
  • additives for cleaning agents must not adversely affect the rinsing and in particular the rinse performance of the cleaner. Ideally, an additive should even improve the overall performance of the cleaner.
  • An essential parameter for dishwashing is the rinse aid performance. It is determined how large the proportion of deposits on the dishes, after they were rinsed.
  • the deposits are essentially mineral compounds, in particular Ca and / or Mg salts, but also surfactant residues.
  • lime mainly leads to undesirable deposits for the user.
