  • the granular washing and cleaning agents according to the invention can be a Have bulk density between about 300 and 1100 g / l. Thereby granules preferred, which has a bulk density above 450 g / l, in particular have between 500 and 1100 g / l.
  • Detergents and cleaning agents can be used in a conventional manner, for example by mixing, granulating, extruding and / or by Spray drying an aqueous slurry and optionally subsequent Admixture of temperature-sensitive components can be produced.
  • detergents and cleaning agents they can be manufactured separately Builders combinations in the form of a spray-dried or granulated Compounds as an admixture to other granular components of the detergent and cleaning agent are used. It is the same possible, the builders and complexing agents individually in a conventional manner To incorporate into the funds in a manner and in any order.
  • Granular detergents of the following composition were prepared and tested in a conventional manner by spray drying.
  • the constituents perborate, bleach activator and enzyme granulate and the complexing agents including the copolymeric polyacrylate and 1-hydroxyethane-1,1-diphosphonate (HEDP) were subsequently mixed in Comparative Example C3.
  • HEDP 1-hydroxyethane-1,1-diphosphonate
  • the test was carried out under practical conditions in household washing machines. For this, the machines charged with 3.5 kg clean laundry and 0.5 kg test fabric, some of the test fabric with usual test soiling was impregnated (for testing the primary washing ability) and consisted partly of white fabric (to check the secondary washing ability). Quarreling from standardized was used as white test fabric Cotton fabric (Krefeld laundry research institute; WFK), nettle (BN), knitwear (cotton jersey; B) and terry toweling (FT) used.
  • WFK white test fabric
  • BN nettle
  • knitwear cotton jersey
  • FT terry toweling
  • Washing conditions tap water of 23 ° d (equivalent to 230 mg CaO / l), used Amount of detergent per detergent and machine 146 g, washing temperature 25 to 90 ° C (heating up time 60 minutes, 15 minutes at 90 ° C), liquor ratio (kg of laundry: liters of wash water in the main wash) 1: 5,7, rinse 4 times with Tap water, centrifuging and drying.
  • the total incrustation was therefore used as a control determined (1st weighing of the untreated tissue, 2nd weighing of the Tissue after 25 washing cycles, 3rd weighing of the tissue after extraction with EDTA, 4. Determination of the so-called "soluble ash” from the difference weighing 2nd and 3rd, 5th ashing of the extracted tissue for determination the remaining ash, 6. Determination of the total incrustation (sum of soluble Ash and residual ash)).
