Definitions
- the invention relates to a concentrate for producing a cleaning liquid and its use for cleaning 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.
- citrate as an essential component is also known from DE 199 58 173.
- US 3,679,609 describes window cleaner concentrates which are also suitable for vehicle windows.
- Such a concentrate can consist of 30 to 40 parts by weight of lower alcohols, 14 to 18 parts by weight of a substance selected from the group consisting of hexylglycol, diethylene glycol, 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 up to 0.75 parts by weight of ethylenediaminetetraacetate, among other components.
- the surfactants can be anionic, such as, for example, the non-characterized surfactants with the trade names Ultra-Wet 60K, Dow Fax, LS 44 or LS 55.
- window cleaning fluids for motor vehicles do not yet satisfactorily meet all the requirements placed on such fluids. These requirements include, for example: sufficient low-temperature stability at low temperatures, good cleaning performance, which requires the windshield to be kept sufficiently moist despite the wind, low tendency to form stress cracks in plastics, particularly in the case of polymethyl methacrylate (plexiglass) used as the rear light panel. These are requirements that do not apply to normal window cleaners for household use.
- Another difference between window cleaners for the home and those for vehicle windows is the different types of soiling and the speed at which they have to be removed. This includes, for example, soiling from road salt or from fly remnants that occur regularly in vehicle windows, but not in the household. For this reason, compositions for window cleaners in the household are not readily transferable to the cleaning of vehicle windows.
- the object of the present invention is to provide a window cleaning liquid and a concentrate therefor which is optimized with regard to the above-mentioned requirements.
- the present invention relates to the use of a cleaning liquid concentrate comprising: a) 35 to 80% by weight of monohydric alcohol with 1 to 4 C atoms, b) a total of 3 to 25% by weight of alkylene glycol, dialkylene glycol or trialkylene glycol with 2 to 3 carbon atoms in each alkylene group, triols with 3 to 5 carbon atoms and / or monoethers thereof, c) 0.05 to 1.5% by weight of anionic surfactants, d) 0.005 to 1.5 %
- organic builders selected from substances containing nitrogen atoms and carboxyl groups, with the exception of ethylenediaminetetraacetate, the sum of the constituents not exceeding 100% by weight and a remainder of 100% by weight consisting of water and / or other active ingredients. and auxiliaries, for the production of a cleaning liquid for the cleaning of windows Motor vehicles, wherein the concentrate is mixed with water in a volume ratio of concentrate: water in the range from 2: 1 to 1: 5.
- the cleaning liquid concentrate to be used according to the invention differs from concentrates according to the prior art except in the special combination of the individual components, in particular in the organic builder d).
- This is selected from organic substances that contain both nitrogen atoms and carboxyl groups. Substances of this type act particularly as chelate complexing agents in the form of their anions.
- EDTA ethylenediaminetetraacetate
- EDTA can have a remobilizing effect for heavy metal ions. This should be avoided if possible.
- the poor biodegradability of EDTA increases this problem. Therefore, the use of EDTA in cleaning fluids for vehicle windows is undesirable and is legally prohibited in some countries.
- a second aspect of the present invention relates to the use of a cleaning liquid which can be obtained by a cleaning liquid concentrate containing a) 35 to 80% by weight of monohydric alcohol with 1 to 4 C atoms, b) a total of 3 to 25% by weight .-% alkylene glycol, dialkylene glycol or trialkylene glycol, each with 2 to 3 carbon atoms in each alkylene group, triols with 3 to 5 carbon atoms and / or monoethers thereof, c) 0.05 to 1.5% by weight of anionic surfactants , d) 0.005 to 1.5% by weight of organic builders, selected from substances containing nitrogen atoms and carboxyl groups, with the exception of ethylenediaminetetraacetate, the sum of the components not exceeding 100% by weight and the remainder remaining at 100% by weight consists of water and / or other active substances and additives, mixed with water in a volume ratio concentrate: water in the range from 2: 1 to 1: 5, as a window cleaning liquid for vehicles.
- a windshield washer fluid for vehicles is commonly used to be dispensed from a reservoir through one or more nozzles as needed Vehicle window is sprayed on and distributed with the wiper. This often happens while driving.
- the window cleaning fluid is allowed to
- the cleaning fluid to be used according to the invention has the advantage over a number of the currently commercially available cleaning fluids for windshield washer systems that it causes no or at most reduced stress crack corrosion in plastic parts, in particular in polymethyl methacrylate. It is therefore particularly suitable for use in a windshield washer system of motor vehicles, the body of which contains plastic components, in particular headlight and taillight lenses made of polymethylacrylate.
- the monohydric alcohol a) is preferably selected from alcohols having 2 to 4 carbon atoms or mixtures thereof. Ethanol and propanols, in particular isopropanol, are particularly suitable. This means that methanol is preferably not used because of its toxic properties. It is therefore preferred that the cleaning liquid concentrate contains as monohydric alcohol a) not more than 2% by weight, preferably not more than 1% by weight and in particular not more than 0.1% by weight of methanol. Methanol can be contained as a denaturing component in ethanol. To avoid this, it is preferable to choose ethanol denatured with methyl ethyl ketone.
- Component a) is preferably at least 37% by weight, in particular at least 40% by weight, of monohydric alcohol. For economic reasons, the concentrate preferably contains a maximum of 70% by weight and in particular a maximum of 60% by weight of monohydric alcohol.
- alkylene glycol, dialkylene glycol or trialkylene glycol each having 2 or 3 carbon atoms in each alkylene group is to be understood to mean that when 3 carbon atoms are present, the two OH groups are either in the 1,2- or in 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 with 1 to 5 carbon atoms, for example with methanol, ethanol, propanol, butanol or pentanol, where the monohydric alcohol is preferably the linear primary alcohol, branched or secondary alcohols can however, must also be etherified with the glycol.
- glycol ethers of longer-chain alcohols for example ethylene glycol hexyl ether, are less preferred.
- the diols or their monoethers b) are preferably present in the concentrate at a concentration of at least 4.5% by weight, in particular at least 6% by weight. Their maximum concentration in the concentrate is preferably not more than 20% by weight.
- the anionic surfactants c) are preferably present in the concentrate with a minimum concentration of 0.1% by weight, in particular 0.2% by weight and particularly preferably 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 each having 8 to 22 carbon atoms in the alkyl group.
- alkyl ether sulfates preference is given to those which are ethoxylated with 1 to 10, preferably 2 to 6, in particular 3 to 5 moles 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 mol 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 preferably selected from iminodisuccinic acid, ethylenediaminedisuccinic acid and polyaspartic acid or their salts which are soluble in one of the mixtures described above. If these builders are used in the form of their salts, sodium ions, potassium ions and / or ammonium ions are particularly suitable as cations.
- window cleaning fluids made from these concentrates are more stable to cold, the less water they are diluted.
- the dilution ratio therefore depends on the cold stability requirement.
- window cleaning liquids which have been prepared from a concentrate to be used according to the invention by dilution with water in a volume ratio between 1: 1 and 1: 4 are liquid down to a temperature of -10 ° C.
- a cleaning liquid concentrate or a cleaning liquid which is suitable for winter operation has been described above.
- the combination of components a) and b) ensures that the cleaning liquid also Temperatures below the freezing point of pure water is still liquid.
- the freezing point of the cleaning liquid is between 0 ° C and -10 ° C and even lower with a suitable composition. This lowering of the freezing point is not necessary for summer operation, when no outside temperatures below the freezing point of pure water are to be expected.
- the window cleaning liquid consists essentially of water and contains surfactants c) and builder substances d) in order to achieve a satisfactory cleaning effect.
- the present invention also includes the use of a concentrate for summer operation, which essentially contains components c) and d).
- a concentrate for summer operation which essentially contains components c) and d).
- the concentrate In contrast to the agent for winter operation, it is not necessary for the concentrate to contain considerable amounts of the alcohol or ether components a) and b). It is therefore possible to provide the active substances c) and d) in water in a much higher concentration than in the winter concentrate. Accordingly, the cleaning liquid concentrate for summer operation for use as a window cleaner can be diluted much more with water than the concentrate for winter operation.
- the present invention relates in a further embodiment to the use of a cleaning liquid concentrate
- a cleaning liquid concentrate comprising: c) 0.5 to 30% by weight of anionic surfactants, d) 0.05 to 10% by weight of organic builders selected from nitrogen atoms and substances containing carboxyl groups, with the exception of ethylenediaminetetraacetate, the sum of the constituents not exceeding 100% by weight and the remainder being 100% by weight water and / or other active substances and auxiliaries, but not more than in total 15% by weight of monohydric or polyhydric alcohols or alkyl ethers thereof, for the preparation of a cleaning liquid for cleaning windows of motor vehicles, the concentrate being mixed with water in a volume ratio of concentrate: water in the range from 1:20 to 1: 200 ,

- the cleaning liquid concentrate contains no more than 0.05% by weight glycol ether of monohydric alcohols with more than 5 carbon atoms in the alkyl group. In this way, stability problems, in particular for the concentrate for winter operation, can be reduced.
- the cleaning liquid concentrate according to the invention contains not more than 0.001% by weight, in particular not more than 0.0001% by weight, of fluorine-containing surfactants.
- the concentrate for summer or winter operation to adjust the pH to the range from 7 to 10 in the diluted window cleaning liquid can contain organic acids or their anions, in particular acetic acid or acetate ions, preferably in amounts between 0.005 to 0 , 1% by weight. If necessary, but not preferred, the concentrate can also contain solubilizers such as cumene sulfonate.
- the invention relates to a cleaning liquid concentrate for producing a cleaning liquid for cleaning windows of motor vehicles, the cleaning liquid concentrate containing the following constituents: a) 35 to 80% by weight of monohydric alcohol with 1 to 4 carbon atoms , b) a total of 3 to 25% by weight of alkylene glycol, dialkylene glycol or trialkylene glycol, each having 2 to 3 carbon atoms in each alkylene group, triols having 3 to 5 carbon atoms and / or monoethers thereof, c) 0.05 to 1 , 5% by weight of anionic surfactants, d) 0.005 to 1.5% by weight of organic builders, selected from substances containing nitrogen atoms and carboxyl groups, with the exception of ethylenediaminetetraacetate and nitrilotriacetate, the sum of the components not exceeding 100% by weight and a remaining remainder consists of 100% by weight of water and / or other active substances and auxiliaries.
- This concentrate in turn represents 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.
- Component b) also serves to keep the panes moist.
- the explanations given above in connection with the use of the concentrate apply to components a) to d) to be used preferably and their amounts.
- This concentrate according to the invention for winter operation differs from that concentrate whose use for the production of a window cleaning liquid has been described above in that the organic builder is said not to contain EDTA or nitrilotriacetate (NTA).
- the invention therefore also relates to a cleaning liquid concentrate for producing a cleaning liquid for cleaning windows of motor vehicles, the cleaning liquid concentrate containing the following constituents: c) 0.5 to 30% by weight of anionic surfactants, d) 0.05 to 10% by weight of organic builders, selected from substances containing nitrogen atoms and carboxyl groups, with the exception of ethylenediaminetetraacetate and nitrilotriacetate, the sum of the components not exceeding 100% by weight and the remainder being 100% by weight Water and / or other active substances and auxiliaries consists, however, not more than a total of 15% by weight of mono- or polyhydric alcohols or alkyl ethers thereof.
- the organic builder d) is preferably selected from iminodisuccinic acid, ethylenediamine disuccinic acid and polyaspartic acid or their respective salts soluble in the concentrate mixture, in particular the sodium, potassium or ammonium salts.
- both the winter concentrate and the summer concentrate can 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 windshield washer systems of motor vehicles, obtainable in that a cleaning liquid concentrate according to claim 9 in a volume ratio between 2: 1 and 1: 5 or a cleaning liquid concentrate according to claim 10 in a volume ratio between 1: 20 to 1: 200 mixed with water or that they are made directly from the components.
- This cleaning liquid is thus obtained either from a winter concentrate by dilution in a volume ratio between 2: 1 and 1: 5, in particular in a volume ratio between 1: 1 and 1: 4.
- This cleaning liquid can be obtained from the summer concentrate with its higher surfactant c) and organic builder d) content by adding the summer concentrate in a volume ratio between 1:20 to 1: 200, in particular between 1:50 to 1: 120 mixed with water.
- the respective cleaning liquid can also be prepared by adding the individual components in the appropriate amounts directly to water. However, this is more cumbersome and therefore less preferred and does not correspond to the practice of preparing cleaning fluids for windscreen washer systems in motor vehicles.
- the ready-to-use cleaning fluid is suitable for all car window cleaning systems. It is also suitable for use with windscreen washer systems that are equipped with wide jet or fan jet nozzles or with swiveling nozzles.
- the diameter of the metal pin is slightly larger than the hole, so that the plastic is put under tension.
- the correct angle at which the metal pin is pressed in is important. This is guaranteed by the press. It is a small hydraulic press with a clamping device and adjustable force.
- test strip pretreated in this way is immediately immersed in the test liquid for 10 seconds at room temperature and then, without further treatment, stored in an open glass.
- the visual assessment of stress cracks takes place after 4 hours and after 24 hours.
- the cycle is then repeated (up to a maximum of 10 cycles).
- test strips, the metal pins and the press come from the company "Kunststofftechnik Buzzi GmbH, D 77761 Schiltach”.
