  • the particular advantage of this known procedure is that the breathability of the microflora in municipal wastewater can surprisingly be increased significantly. This leads to a noticeable reduction in the environmental impact, because the disinfectant effect is due to degradable natural substances, ie the lime-dissolving water-soluble substance, there in the form of a lime-dissolving water-soluble acid, the germ-inhibiting organic substances as well as the germ-promoting organic substances can be of natural origin.
  • This known proposal can therefore be used in a wide range of applications, such as in the entire sanitary area, such as in particular in toilet bowls, urine pools, bathtubs, wash basins, shower trays and the like.

  • the compounds of the formula (I) are used in whole or in part in the form of their salts or other precursors, which can promote solubility. In individual cases, this can only lead to the desired solubility in the sanitary cleaner according to the invention.

  • urea phosphate has an exceptionally good descaling capacity.
  • due to the urea released in solution it promotes desirable effects in the second phase of action. Its hazard potential is just as harmless as that of citric acid.
  • Urea phosphate thus not only satisfies the requirement of the state of the art to be assessed positively according to WO 94/28100 for the addition of urea, but also at the same time also fulfills the requirement of a safe and effective limescale-dissolving effect which, for example, is significantly stronger than citric acid. Therefore, the lime-dissolving, water-soluble substance, for example in the form of an acid, such as in particular citric acid, can be wholly or partly by the mono-substance
  • urea phosphate is advantageous both for the increased cleaning effect in the first and for increasing the microbial breakdown of organic substances in the second phase of action.
