Definitions

  • the present invention relates to a gel detergent, which is preferred can be used in flush toilets.
  • solid detergents in piece form become automatic Keeping toilets clean. These are either in the toilet bowl or attached in the water tank.
  • the moldings are with everyone Flushing process overflows with water, where they gradually dissolve and release their active cleaning agents during this time.
  • these cleaning tablets also contain perfume for room scenting or disinfectant agents for hygiene optimization.
  • the described lumpy detergent tablets are in suitable for this Containers partially applied with special refill options.
  • the moldings described are usually after casting, pressing, Extruding or pelletizing processes that have a high technical Effort and often due to the temperature load (casting / extrusion process) suffer undesirable loss of perfume.
  • Such a shaped body is described, for example, in the British patent application GB 2 288 186 A. It is a "gel cleaning block", which should contain surfactants, guar gum and monovalent ions. The production takes place at 90 ° C, then the block is poured into a mold and solidifies. Individual refilling of any quantities is therefore not possible.
  • the object of the invention was to develop a system which described the Does not have disadvantages. Surprisingly, it was found that special gel-like preparations with pseudoplastic properties the effort of Reduce production considerably and, because of the simple technology, it is cheaper are to be produced.
