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 active chlorine-releasing compounds and which, in order to improve the wetting, may contain minor additions of a low-foaming nonionic surfactant.
  • inorganic salts such as alkali phosphates, alkali silicates and alkali carbonates and active chlorine-releasing compounds
  • a low-foaming nonionic surfactant 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 thickeners and active chlorine compounds, the agents being applied to the material to be cleaned and coated with water over a longer period of time due to their gel structure 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.
  • US Pat. No. 3,882,038 discloses cleaning agents for hard surfaces such as tiles, windows, stoves and the like, which consist essentially of monobutyl or monoamyl ethers of propylene glycol, dipropylene glycol or tripropylene glycol, a nonionic surfactant and water. They can also contain hydrotropes and thickeners and can be adjusted to different pH values. The use as a pretreatment or soaking agent for stubborn stains on dishes before the machine cleaning process is not recommended.

  • the use of the agents is far from that of the present invention.
  • 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 used 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 means of spray pumps, brushes, foam guns, spray cans, then that Immediately place items to be washed in a suitable position in the dishwasher, ie with the pot opening downwards 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.
  • the invention therefore relates to the use of agents which 0.5-20, preferably 1-15% by weight of nonionic, especially low-foaming surfactants, 0.5 - 25, preferably 1 - 20% by weight of polyhydric aliphatic alcohols and / or glycol ethers, 0.5-10, preferably 1-8% by weight of a hydrotropic compound, 0.01 - 6, preferably 0.05 - 5 wt .-% viscosity regulators and optionally fragrances and dyes, preservatives and very small amounts of acidic or alkaline agents for adjusting the pH in aqueous solution or suspension and to a viscosity of at least 5, preferably at least 20 mPas and a pH of 2-7, preferably 3-6, for pretreating or soaking stubbornly soiled dishes for the machine cleaning process.
  • agents which 0.5-20, preferably 1-15% by weight of nonionic, especially low-foaming surfactants, 0.5 - 25, preferably 1 - 20% by weight of polyhydric
  • Suitable nonionic, preferably low-foaming surfactants include the ethylene oxide adducts with higher molecular weight propylene glycols with a molecular weight of 900 to 4000 and adducts with 1 to 10 moles of ethylene oxide or 1 to 10 moles of ethylene oxide and 1 to 7 moles of 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 chain length C12-C18 and corresponding alkylene oxide adducts with nonylphenols.
  • the terminal hydroxyl groups of the adducts can also be converted into acetals or ketals, "end-capped", by reacting one mole of an aldehyde or ketone with two moles of an adduct each.
  • Ethoxylated diols with up to 18 carbon atoms and terminal or internal vicinal hydroxyl groups and the corresponding monoglycol ether diols are also suitable.
  • 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 achieve a desired viscosity of the composition used 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.
