Definitions

  • the invention relates to a concentrate for the production of a cleaning fluid and its use for the cleaning of windows in motor vehicles, in particular for use in windscreen washer systems. Furthermore, it relates to the ready-to-use cleaning liquid which can be prepared from the concentrate by dilution with water.
  • U.S. 3,679,609 describes disc cleaner concentrates that are also suitable for vehicle windows.
  • Such a concentrate may be composed of 30 to 40 parts by weight of lower alcohols, 14 to 18 parts by weight of a substance selected from hexylglycol, diethyleneglycol, ethylene glycol and glycerol, up to 15 parts by weight of ethylene glycol monoethyl ether, 1.5 to 2.5 parts by weight of surfactant and 0.25 to 0.75 parts by weight of ethylenediamine tetraacetate in addition to other components.
  • the surfactants may be anionic, such as the unspecified surfactants with the trade names Ultra-Wet 60K, Dow Fax, LS 44 or LS 55.
  • window cleaning fluids for motor vehicles do not yet solve all the demands placed on such liquids equally satisfactorily. These requirements include, for example: sufficient cold stability at low temperatures, good cleaning performance, which requires a sufficiently long moisturizing the windshield despite wind, little tendency to form stress cracks in plastics, especially in the used as a backlight disc polymethyl methacrylate (Plexiglas). These are requirements that do not apply to normal window cleaner for domestic use.
  • Another difference between window cleaner for household and those for vehicle windows is the different type of stains and the speed with which they must be removed. These include, for example, soiling from road salt or fly debris, which regularly occurs in vehicle windows, but does not occur in the household. Therefore, compositions for window cleaner in the household are not readily transferred to the cleaning of vehicle windows.
  • the present invention has as its object to provide a window cleaning liquid and a concentrate therefor, which is optimized in terms of the above requirements.
  • the cleaning liquid concentrate to be used according to the invention differs from concentrates according to the prior art except by the specific amount combination of the individual components, in particular by the organic builder d).
  • This is selected from organic substances containing both nitrogen atoms and carboxyl groups. Such substances act especially as their anions as chelating complexing agents.
  • EDTA ethylenediamine tetraacetate
  • EDTA can be remobilising for heavy metal ions. This should be prevented if possible. The poor biodegradability of EDTA increases this problem. Therefore, the use of EDTA in cleaning fluids for vehicle windows is undesirable and prohibited by law in some countries.
  • a windscreen cleaning fluid for vehicles is usually used so that it can be supplied from a reservoir through one or more nozzles on the Vehicle window is sprayed and distributed with the windscreen wiper. Often this happens while driving.
  • the windscreen cleaning fluid must not evaporate too quickly despite the wind.
  • the component b) in conjunction with the water present for a sufficiently long moisturizing the disc is usually used so that it can be supplied from a reservoir through one or more nozzles on the Vehicle window is sprayed and distributed with the windscreen wiper. Often this happens while driving.
  • the windscreen cleaning fluid must not evaporate too quickly despite the wind.
  • the cleaning fluid to be used according to the invention has the advantage over a number of currently commercially available cleaning fluids for windscreen washer systems that it causes no or at most a reduced stress cracking corrosion in plastic parts, in particular in polymethyl methacrylate. It is therefore particularly suitable for use in a windscreen washer system of motor vehicles, the body of which contains plastic components, in particular headlamp and tail lamp disks made of polymethyl acrylate.
  • the monohydric alcohol a) is preferably selected from alcohols having 2 to 4 carbon atoms or mixtures thereof.
  • ethanol and propanols, especially isopropanol are suitable. This means that it is preferable to dispense with the use of methanol because of its toxic properties. Therefore, it is preferred that the cleaning fluid concentrate contains as the monohydric alcohol a) not more than 2 wt .-%, preferably not more than 1 wt .-% and in particular not more than 0.1 wt .-% methanol.
  • Methanol may be contained in ethanol as a denaturant component. To avoid this, it is preferable to choose ethanol denatured with methyl ethyl ketone.
  • at least 37% by weight, in particular at least 40% by weight, of monohydric alcohol are present as component a).
  • the concentrate preferably contains not more than 70% by weight and in particular not more than 60% by weight of monohydric alcohol.
  • alkylene glycol, dialkylene glycol or trialkylene glycol having in each case 2 or 3 C atoms in each alkylene group is to be understood as meaning that in the presence of 3 C atoms, the two OH groups are present either in the 1,2- or 1,2-carbon atoms the 1,3-position can stand.
  • the component b) is preferably selected from glycerol as an example of a triol, ethylene glycol, propylene glycol, in particular 1,2-propylene glycol, diethylene glycol, dipropylene glycol, triethylene glycol, and monoethers of ethylene glycol or propylene glycol with monohydric alcohols having 1 to 5 carbon atoms, for example with Methanol, ethanol, propanol, butanol or pentanol.
  • the monohydric alcohol is preferably the linear primary alcohol. Branched or secondary alcohols can but also be etherified with the glycol. For reasons of product stability, glycol ethers of relatively long-chain alcohols, for example ethylene glycol hexyl ether, are less preferred.
  • the diols or their monoethers b) are present in the concentrate, preferably at a concentration of at least 4.5% by weight, in particular of at least 6% by weight. Preferably, their maximum concentration in the concentrate is not more than 20% by weight.
  • the anionic surfactants c) are present in the concentrate, preferably with a minimum concentration of 0.1% by weight, in particular of 0.2% by weight and more preferably of 0.3% by weight.
  • the upper limit of the surfactant concentration is preferably 1% by weight, in particular 0.7% by weight.
  • the anionic surfactants c) are preferably selected from the group of alkyl sulfates, alkylaryl sulfates, alkyl sulfonates and alkyl ether sulfates having in each case 8 to 22 carbon atoms in the alkyl group.
  • alkyl ether sulfates When alkyl ether sulfates are used, preference is given to those which are ethoxylated with from 1 to 10, preferably from 2 to 6, in particular from 3 to 5, mol of ethylene oxide (EO) per mole of alcohol.
  • EO ethylene oxide
  • an ether sulfate of a lauryl / myristyl alcohol mixture with an average of 4 moles of EO can be used.
  • the minimum concentration of the organic builder d) is preferably 0.01% by weight, the upper limit preferably 0.5% by weight, particularly preferably 0.3% by weight.
  • the organic builder d) is selected from iminodisuccinic acid, ethylenediamine disuccinic acid and polyaspartic acid or in each case their salts soluble in one of the mixtures described above. If these builders are used in the form of their salts, suitable cations are, in particular, sodium ions, potassium ions and / or ammonium ions.
  • Windscreen cleaning fluids made from these concentrates are all the more cold-stable, with less water being diluted.
  • the dilution ratio therefore depends on the requirement for cold stability.
  • window cleaning liquids which were prepared from a concentrate to be used according to the invention by dilution with water in a volume ratio of between 1: 1 and 1: 4, are liquid up to a temperature of -10 ° C.
  • the above has described the use of a cleaning fluid concentrate or cleaning fluid suitable for winter operation.
  • the combination of components a) and b) ensures that the cleaning fluid even at Freezing temperatures of pure water is still fluid.
  • the solidification point of the cleaning liquid is between 0 ° C and -10 ° C and with suitable composition even lower.
  • this freezing point depression is not required.
  • the cleaning fluid concentrate contain no more than 0.05% by weight of glycol ethers of monohydric alcohols having more than 5 C atoms in the alkyl group. This can reduce stability problems, especially for the concentrate for winter operation.
  • For the summer concentrate come as other active ingredients and auxiliaries, in particular substances into consideration, which improve the biostability of the concentrate and a cleaning liquid prepared therefrom.
  • examples which may be mentioned are alcohols of group a), phenoxyethanol and N-hydroxymethylglycerol, which may be present in amounts of from 0.1 to 10% by weight, depending on the extent of their biostabilizing action.
  • the cleaning liquid concentrate of the invention contains not more than 0.001 wt .-%, in particular not more than 0.0001 wt .-% fluorine-containing surfactants.
  • the concentrate for adjusting the pH to the range of 7 to 10 in the diluted window cleaning liquid organic acids or their anions, in particular acetic acid or acetate ions, preferably in amounts between 0.005 to 0.1 wt. %.
  • the concentrate may also contain solubilizers such as cumene sulfonate.
  • This concentrate is in turn a concentrate for winter operation.
  • Components a) and b) have the task of lowering the freezing point in the diluted ready-to-use window cleaning liquid compared to pure water. Furthermore, component b) serves to keep the discs moist.
  • component a) to d) and their amounts the explanations given above in connection with the use of the concentrate apply.
  • the organic builder d) is selected from iminodibemic acid, ethylenediamine disuccinic acid and polyaspartic acid or in each case their salts soluble in the concentrate mixture, in particular the sodium, potassium or ammonium salts.
  • the concentrate may contain additional components such as biocides, as described above in connection with the use of the concentrates.
  • the present invention relates to a cleaning liquid for windscreen washer systems of motor vehicles, obtainable by mixing a cleaning liquid concentrate according to claim 6 in a volume ratio between 2: 1 and 1: 5 with water or by adding directly from the components manufactures.
  • This cleaning liquid is thus obtained from a winter concentrate by dilution in a volume ratio of between 2: 1 and 1: 5, in particular in a volume ratio of between 1: 1 and 1: 4.
  • this is more cumbersome and therefore less preferred and does not conform to the practice of preparing cleaning fluids for windshield washer systems of motor vehicles.
  • the ready-to-use cleaning fluid is suitable for all car window cleaning systems. It is also suitable for use in windscreen washer systems equipped with wide jet or fan jet nozzles or with swiveling nozzles.
