Definitions

  • alkaline cleaning agent mixtures are used for the automatic cleaning of dishes, which essentially consist of inorganic salts such as alkali phosphates, alkali silicates and alkali carbonates and compounds which release active chlorine and which, if necessary, contain small amounts of a low-foaming nonionic surfactant to improve wetting.
  • inorganic salts such as alkali phosphates, alkali silicates and alkali carbonates and compounds which release active chlorine and which, if necessary, contain small amounts of a low-foaming nonionic surfactant to improve wetting.
  • these mixtures At normal cleaning temperatures of 55 ° C to 65 ° C, these mixtures generally have good cleaning properties against all types of soiling.
  • the invention was therefore based on the object of finding a pretreatment or soaking agent which is easy to use and leads to the complete, automatic removal of problem soils in the mechanical cleaning process.
  • a pretreatment or soaking agent which is easy to use and leads to the complete, automatic removal of problem soils in the mechanical cleaning process.
  • strongly alkaline pot cleaning agents are known, which contain various thickening agents and active chlorine compounds, the agents being applied to the material to be cleaned and coated with water for a long time due to their gel structure the contact point remain and therefore have a particularly sustainable effect.
  • agents as described in the preceding invention would be suitable as pretreatment or cleaning agents for use in dishwashers.
  • the exposure time of the desired agent should on the one hand be kept as short as possible so as not to delay work processes, but on the other hand, even after treatment with this agent, even if the items to be washed have been in the dishwasher for a longer period of time, they should be prevented from drying out again with the agent will.
  • the agent according to the invention should be used in such a way that the user brings the food residues, which are difficult to remove, for example in a saucepan or in a frying pan, into contact with the agent, for example by spray pumps, brushes, foam guns, spray cans, and then the dishes immediately in a convenient position in the dishwasher, ie with the pot opening down in the direction of the water spray, the viscous product essentially adhering to the pot surface and starting the cleaning process as required. It should not be necessary to rinse out the pretreatment or soaking agent before the cleaning process.
  • Such pretreatment and soaking agents according to the invention for stubbornly soiled dishes for the complete, automatic removal of problem soils in the mechanical cleaning process are characterized in that they 0.5 to 20, preferably 1 to 15% by weight of nonionic, especially low-foaming, surfactants, 0.5 to 25, preferably 1 to 20% by weight of polyhydric aliphatic alcohols and / or glycol ethers, 0.5 to 10 preferably 1 to 8% by weight of a hydrotropic compound and 0.01 to 6, preferably 0.05 to 5 wt .-% viscosity regulators contained in aqueous suspension or solution and adjusted to a viscosity of at least 5, preferably at least 20 mPas.
  • Suitable nonionic, preferably low-foaming surfactants include ethylene oxide adducts with higher molecular weight propylene glycols with a molecular weight of 900 to 4000 and adducts with 1 to 10 mol ethylene oxide, or 1 to 10 mol ethylene oxide and 1 to 7 mol propylene oxide with higher molecular weight fatty alcohols with 8 to 22, preferably 10 up to 16 carbon atoms in the molecule or their naturally occurring mixtures and synthetic alcohols, for example those prepared by oxosynthesis, of the chain length C12-C18 and corresponding alkylene oxide adducts with nonylphenols.
  • Suitable humectants which are added to the formulations according to the invention in order to avoid re-drying together with the stubborn stains are the polyhydric aliphatic alcohols or glycol ethers or mixtures thereof, such as e.g. Ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol or diethylene glycol monobutyl ether.
  • the preferred humectant is glycerin.
  • Short-chain monohydric alcohols with 2 to 4 carbon atoms in the molecule e.g. Ethanol, propanol, butanol or preferably isopropanol or hydrotrope e.g. Octyl sulfate, benzene, xylene, toluene or cumene sulfonate or polydiols with molecular weights up to 1000 can be used.
  • Suitable thickeners are added to adjust the viscosity of the composition according to the invention.
  • It is e.g. B. water-soluble polyethylene glycols with molecular weights between 105 and 4. 106, preferably between 4. 105 and 9. 105.
  • Such raw materials are available, for example, under the name Polyox® from Union Carbide.
  • Also suitable are, for. B. Efacos GT 282® from Akzo, a nonionic polymer (dialkyl polyglycols) with an average molecular weight of approximately 3000, e.g. B. different Carbopol® types from BF Goodrich as representatives of the polycarboxylates, layered silicates such as Laponite RD® from Laporte Ind.
  • Attapulgite clays such as e.g. B. Attagel 40® from Chemie-Mineralien KG, polysaccharides such as e.g. B. Kelzan® from Kelco or Rhodopol 23® from Rhône-Poulenc Ind., Cellulose derivatives such as Tylose H200YP® from Hoechst AG, C12 to C20 fatty alcohol ethoxylates from about 40 to 150 EO units.
  • compositions according to the invention In order to adjust the compositions according to the invention to the preferred pH range from 3 to 6, small amounts of an acid or a salt are added if necessary. Preferred substances for this are acetic acid, citric acid, lactic acid, tartaric acid. To set an exact pH, small amounts of e.g. As sodium hydroxide, sodium hydrogen carbonate or sodium carbonate may be required. Depending on the recipe, the formulations according to the invention are clear, cloudy or opaque solutions.
  • the invention further relates to a method for cleaning stubbornly soiled dishes, which is characterized in that the soiled areas are coated with an agent according to claims 1 to 3, the dishes with the coated surface in the direction against the jet of water circulation in a crockery basket classifies the dishwasher and, after any exposure time, preferably after at least 30 minutes, initiates the normal machine cleaning process and allows it to run.
  • test results listed below show the advantages of the pretreatment or soaking agents according to the invention.
  • the household dishwasher type Miele G 520 was used.
  • the pots with the test soils described later were cleaned in the cleaning cycle at 55 ° C and for the purpose of better comparability without the subsequent use of rinse aid.
  • 4 pots - opening against the spray jet, down here - were placed in the lower dishwasher basket.
  • the effect of the pretreatment or soaking agent according to the invention was compared with the cleaning performance which results from the use of 30 g of a conventional standard cleaning agent alone, consisting of: 40% by weight pentasodium triphosphate, anhydrous 45% by weight sodium metasilicate, anhydrous 5% by weight sodium carbonate, anhydrous 1% by weight of trichloroisocyanuric acid 1 wt .-% of an adduct of 5 moles of ethylene oxide (E0) and 4 moles of propylene oxide (P0) to a C12-C14 fatty alcohol Rest of water.
  • a conventional standard cleaning agent alone consisting of: 40% by weight pentasodium triphosphate, anhydrous 45% by weight sodium metasilicate, anhydrous 5% by weight sodium carbonate, anhydrous 1% by weight of trichloroisocyanuric acid 1 wt .-% of an adduct of 5 moles of ethylene oxide (E0) and 4 moles of prop
  • test soils were mainly produced in enamel pots from Silit, diameter 16 cm and height 8 cm. Tests were also carried out in stainless steel pots, diameter 16 cm and height 16 cm.
  • the mean value of the cleaning performance rating for the soiling was from 1 to 3.
  • Mixture 2 was placed in a saucepan and heated on an oil bath (200 ° C.) for 1 minute. The pot was removed from the heat source and Mix 1 mixed in with a wooden spoon. The The stirred pudding was then allowed to burn on the oil bath for 10 minutes without stirring.
