Definitions

  • the invention relates to alkaline, phosphate-free cleaning agents in powder form, in particular for dishes, these agents being stable in storage and automatically meterable for dishwashers.
  • the automatic dosing is of outstanding importance. On the one hand, this prevents users from coming into contact with powders containing alkaline chemicals unnecessarily often, and on the other hand ensures that the concentration of cleaning agent is always uniform, which guarantees that dishes are cleaned properly.
  • the automatic dosage is for the rational workflow z. B. indispensable in commercial kitchens and is usually state of the art.
  • the automatic dosing of powdered dishwashing detergent takes place with the help of conductivity meters, which, for . B. are coupled with overflow or rinse-out dispensers.
  • the detergent in the dosing devices must not clump and / or harden when water is added, but should form a loose slurry that is as stable as possible.
  • detergent stocks are stored regularly and of course it is also important that their storage behavior is flawless even at elevated temperatures, which can occasionally rise up to 50 ° C. that is, the product does not cake and harden under any circumstances, but maintains the free-flowing properties that it is aware of during its manufacture. These properties are imperative for loading and stocking the dosing machines mentioned.
  • Storage-stable and meterable cleaning agents for automatic dishwashing with the properties specified above have so far been able to be produced by using suitable commercially available raw materials, in particular sodium tri-polyphosphates which are specially anhydrated. At first, this standard could not be easily maintained with phosphate-free cleaners.
  • the presence of potassium and sodium ions is decisive, 20 to 80, preferably 30 to 60% by weight of the mixture constituents being present as potassium salts. It is assumed that the size of the potassium ions, when mixed with Na salts, act in the sense of a crystal lattice disorder and thus prevent the formation of compact crystals.
  • the ammonium ion NH 4 ⁇ or cations from organo-substituted ammonium compounds NR 1 R 2 R 3 R 4 ⁇ behave in a similarly favorable manner, where R preferably denotes hydrocarbon radicals having 1 to 4 carbon atoms. But also connections with longer-chain residues such.
  • B. dimethyl-distearylammonium chloride can produce the desired effect.
  • Suitable alkali carbonates include anhydrous sodium carbonate and anhydrous potassium carbonate, and especially a mixture of anhydrous sodium and potassium carbonate. Soda-water containing soda should be avoided for use in the agents according to the invention.
  • Potassium metasilicate can be used as the anhydrous alkali metasilicate, but preference is given to commercially available sodium metasilicate in anhydrous form. Metasilicates containing hydrate are also unsuitable for use in the agents according to the invention.
  • Alkali hydroxide is used as solid potassium hydroxide or preferably as solid sodium hydroxide, again preferably as so-called prills.
  • the hydrated water content of these compounds should be as low as technically possible.
  • Part of the cleaning-active carbonate component can be replaced by cleaning-inactive sulfates, preferably as anhydrous potassium sulfate introduce the required amount of potassium ions into the mixture.
  • Preferred compounds containing active chlorine are the alkali metal salts of dichloroisocyanuric acid, namely potassium dichloroisocyanurate or sodium dichloroisocyanurate, the latter anhydrous or, if appropriate, also here as a dihydrate, but also trichloroisocyanuric acid.
  • water-soluble complexing agents in the form of various polyphosphonates can also be used. These include the sodium and potassium salts of ethane-1-hydroxy-1,1-diphosphonic acid, methylene diphosphonic acid, ethane-1,1,2-triphosphonic acid, hydroxymethane diphosphonic acid, ethane-1-hydroxy-1,1,2-triphosphonic acid, propane 1,1,3,3-tetraphosphonic acid, propane-1,1,2,3-tetra-phosphonic acid and propane-1,2,2,3-tetraphosphonic acid or 2-phosphonobutane tricarboxylic acid-1,2,4.
  • the cleaning agents were produced by mixing the individual constituents in any order in customary technical mixing apparatus, such as, for example, a Lödige mixer or a Schugi mixer. In some cases, small amounts of 0.5 to 1.0% by weight paraffin oil were added to bind dust.
  • the cleaning agents were stored in commercially available watertight containers at a temperature of 45 ° C for a period of 6 months and remained in place stable, ie they did not bake, but remained pourable.
