Abstract
Description
Die vorliegende Erfindung betrifft die Verwendung von Reinigungsmitteln, die in unverdünnter Form zur Reinigung harter Oberflächen, insbesondere Glas, eingesetzt werden können.The present invention relates to the use of cleaning agents which can be used in undiluted form for cleaning hard surfaces, in particular glass.
Bei den heute üblichen Reinigungsmitteln für harte Oberflächen handelt es sich in der Regel um wäßrige Zubereitungen, die als wesentliche Wirkstoffe oberflächenaktive Substanzen, organische Lösungsmittel sowie gegebenenfalls Komplexbildner für die Härtebestandteile des Wassers, Abrasivstoffe und reinigend wirkende Alkalien enthalten. Reinigungsmittel, die vor allem für die Reinigung von Glas- und Keramikoberflächen bestimmt sind, werden häufig als Lösungen der Wirkstoffe in einem Gemisch aus Wasser und mit Wasser mischbaren organischen Lösungsmitteln, in erster Linie niedere Alkohole und Glykolether, formuliert. Beispiele derartiger Mittel finden sich in der deutschen Offenlegungsschrift 22 20 540, den US-Patentschriften 3 839 234 und 3 882 038 sowie in den EP-Patentanmeldungen 344 847 und 393 772.The cleaning agents for hard surfaces which are customary today are generally aqueous preparations which contain, as essential active substances, surface-active substances, organic solvents and, if appropriate, complexing agents for the hardness constituents of water, abrasive substances and cleaning alkalis. Detergents, which are primarily intended for cleaning glass and ceramic surfaces, are often formulated as solutions of the active substances in a mixture of water and water-miscible organic solvents, primarily lower alcohols and glycol ethers. Examples of such agents can be found in German Offenlegungsschrift 22 20 540, US Pat. Nos. 3,839,234 and 3,882,038, and EP Patent Applications 344,847 and 393,772.
Bei der Anwendung der Reinigungsmittel stellt sich neben der selbstverständlichen Forderung nach hoher Reinigungsleistung auch die Forderung nach möglichst einfacher und bequemer Anwendung der Mittel. Meist wird erwartet, daß die Mittel bereits bei einmaligem Auftrag ohne weitere Maßnahmen die gewünschte Wirkung liefern. Hier stellt sich vor allem bei Anwendung auf glatten Oberflächen, insbesondere solchen, die wie Glas oder Keramik spiegelnd reflektieren können, Schwierigkeiten dadurch ein, daß Mittel, die gut reinigen, meist nicht streifenfrei auftrocknen, während solche Mittel, die im wesentlichen ohne sichtbare Rückstände auftrocknen, nur eine begrenzte Reinigungswirkung aufweisen. Um bei annehmbaren Rückstandsverhalten eine hinreichende Reinigungswirkung, insbesondere gegenüber fettigen Anschmutzungen zu erreichen, ist es notwendig, den Reinigungsmitteln neben organischen Lösungsmitteln auch größere Mengen an mehr oder weniger flüchtigen Alkalien zuzusetzen. Hier haben insbesondere Ammoniak und Alkanolamine Anwendung gefunden. Höhere Konzentration an Ammoniak bzw. Amin bewirken allerdings neben einer merklichen Geruchsbelästung eine entsprechende Erhöhung des pH-Wertes in der Reinigungsmittellösung mit der Folge, daß empfindlichere Oberflächen, wie beispielsweise Lackflächen, von diesen Reinigungsmitteln deutlich angegriffen werden. Es bestand daher nach wie vor Bedarf an Reinigungsmitteln, die bei hoher Reinigungsleistung die genannten Nachteile nicht aufweisen.When using the cleaning agents, in addition to the self-evident requirement for high cleaning performance, there is also the requirement for the simplest and most convenient use of the agents. Most of the time, it is expected that the funds will deliver the desired effect even with a single application without further measures. Difficulties arise especially when used on smooth surfaces, especially those that can reflect like glass or ceramics, because agents that clean well usually do not dry without streaks, while agents that dry essentially without visible residues , have a limited cleaning effect. In order to achieve a sufficient cleaning effect with an acceptable residue behavior, especially against greasy soiling, it is necessary to use the cleaning agents in addition to adding organic solvents, larger amounts of more or less volatile alkalis. Ammonia and alkanolamines in particular have been used here. Higher concentrations of ammonia or amine, however, cause not only a noticeable odor nuisance, but also a corresponding increase in the pH value in the cleaning agent solution, with the result that more sensitive surfaces, such as paint surfaces, are significantly attacked by these cleaning agents. There was therefore still a need for cleaning agents which did not have the disadvantages mentioned with high cleaning performance.
Die vorliegende Erfindung bietet eine Lösung dieses Problems durch Verwendung eines wäßrigen Reinigungsmittels, das anionisches Tensid, wassermischbares organisches Lösungsmittel aus der Gruppe der Alkohole, Etheralkohole und deren Gemische, Alkali aus der Gruppe Ammoniak, Alkanolamin mit bis zu 9 C-Atomen und deren Gemische, sowie eine Carbonsäure mit bis zu 6 C-Atomen oder ein Gemisch solcher Carbonsäuren enthält, wobei das Äquivalentverhältnis von Amin und/oder Ammoniak zu Carbonsäure zwischen 1 : 0,9 und 1 : 0,1 liegt. Vorzugsweise enthält das Reinigungsmittel darüber hinaus auch nichtionisches Tensid.The present invention offers a solution to this problem by using an aqueous cleaning agent which contains anionic surfactant, water-miscible organic solvent from the group of alcohols, ether alcohols and their mixtures, alkali from the group ammonia, alkanolamine with up to 9 C atoms and mixtures thereof, and also contains a carboxylic acid with up to 6 carbon atoms or a mixture of such carboxylic acids, the equivalent ratio of amine and / or ammonia to carboxylic acid being between 1: 0.9 and 1: 0.1. The detergent preferably also contains nonionic surfactant.
Das erfindungsgemäß verwendete Reinigungsmittel weist gegenüber einem solchen Mittel, das die gleiche Menge Alkali ohne Carbonsäurezusatz enthält, einen sehr viel schwächeren Geruch aus. Dagegen wird die hohe Reinigungsleistung durch den Zusatz der Carbonsäure praktisch nur unwesentlich verringert. Obwohl durch den Zusatz der Carbonsäure Ammonium- bzw. Aminsalze gebildet werden, zeigt das erfindungsgemäß verwendete Mittel ein ausgezeichnetes Rückstandsverhalten. Schmierige Rückstände, wie sie häufig bei alkanolaminreichen Mitteln zu beobachten sind, werden durch den Carbonsäurezusatz weitgehend vermieden. Auf diese Weise bleibt der Glanz der Oberflächen erhalten, ohne daß ein Nachspülen oder Nachpolieren notwendig wäre.The cleaning agent used according to the invention has a much weaker odor compared to such a agent which contains the same amount of alkali without the addition of carboxylic acid. In contrast, the high cleaning performance is practically only slightly reduced by the addition of the carboxylic acid. Although ammonium or amine salts are formed by the addition of the carboxylic acid, the agent used according to the invention shows excellent residue behavior. Greasy residues, as can often be observed with agents rich in alkanolamine, are largely avoided by the addition of carboxylic acid. In this way, the gloss of the surfaces is maintained without the need for rinsing or polishing.
Es folgt nun eine Beschreibung der einzelnen Bestandteile des verwendeten Mittels:There now follows a description of the individual components of the agent used:
Als oberflächenaktive Substanzen eignen sich für die erfindungsgemäßen Mittel Tenside, insbesondere aus den Klassen der anionischen und nichtionischen Tenside. Vorzugsweise werden Mischungen aus anionischen und nichtionischen Tensiden eingesetzt. Die Menge an anionischem Tensid liegt beim anwendungsfertigen Mittel vorzugsweise zwischen 0,05 und 0,3 Gew.-%, insbesondere zwischen 0,08 und 0,2 Gew.-%, bezogen auf das fertige Mittel. In konzentrierten Mitteln, die vor der Anwendung noch verdünnt werden müssen, liegt die Konzentration entsprechend höher und kann vorzugsweise bis zu 3 Gew.-% betragen. Sofern neben anionischen Tensiden auch nichtionische Tenside verwendet werden, liegt deren Konzentration in den anwendungsfertigen Mitteln vorzugsweise nicht über 0,15 Gew.-% und insbesondere zwischen 0,02 und 0,08 Gew.-%. In Konzentraten liegt sie entsprechend höher, vorzugsweise bis etwa 1 Gew.-%.Suitable surfactants for the agents according to the invention are surfactants, in particular from the classes of anionic and nonionic Surfactants. Mixtures of anionic and nonionic surfactants are preferably used. The amount of anionic surfactant in the ready-to-use agent is preferably between 0.05 and 0.3% by weight, in particular between 0.08 and 0.2% by weight, based on the finished agent. In concentrated agents which still have to be diluted before use, the concentration is correspondingly higher and can preferably be up to 3% by weight. If nonionic surfactants are also used in addition to anionic surfactants, their concentration in the ready-to-use compositions is preferably not more than 0.15% by weight and in particular between 0.02 and 0.08% by weight. It is correspondingly higher in concentrates, preferably up to about 1% by weight.
Als anionische Tenside eignen sich vorzugsweise Alkylbenzolsulfonate mit 9 bis 16 C-Atomen im Alkylteil, insbesondere mit etwa 12 C-Atomen im Alkylteil, Alkansulfonate mit 12 bis 20 C-Atomen im Alkylteil, Monoalkylsulfate mit 12 bis 18 C-Atomen im Alkylteil, Alkylethersulfate mit 12 bis 18 C-Atomen im Alkylteil und 2 bis 6 Ethylenoxideinheiten (E0) im Etherteil sowie Sulfobernsteinsäureester mit 8 bis 16 C-Atomen in den Alkoholresten. Die anionischen Tenside werden vorzugsweise als Natriumsalze eingesetzt, können aber auch in Form von Ammonium- oder Aminsalzen verwendet werden.Suitable anionic surfactants are preferably alkylbenzenesulfonates with 9 to 16 C atoms in the alkyl part, in particular with about 12 C atoms in the alkyl part, alkanesulfonates with 12 to 20 C atoms in the alkyl part, monoalkyl sulfates with 12 to 18 C atoms in the alkyl part, alkyl ether sulfates with 12 to 18 carbon atoms in the alkyl part and 2 to 6 ethylene oxide units (E0) in the ether part and sulfosuccinic acid esters with 8 to 16 carbon atoms in the alcohol residues. The anionic surfactants are preferably used as sodium salts, but can also be used in the form of ammonium or amine salts.
Beispiele derartiger Tenside sind Natriumlaurylethersulfat mit 2 E0, Natriumkokosalkylsulfat, Natrium-sec.-Alkansulfonat mit ca. 15 C-Atomen sowie Natriumdioctylsulfsosuccinat. Als besonders geeignet haben sich Fettalkylsulfate mit 12 bis 14 C-Atomen erwiesen.Examples of such surfactants are sodium lauryl ether sulfate with 2 E0, sodium cocoalkyl sulfate, sodium sec-alkane sulfonate with about 15 carbon atoms and sodium dioctyl sulfosuccinate. Fatty alkyl sulfates with 12 to 14 carbon atoms have proven to be particularly suitable.
Als nichtionische Tenside sind vor allem ethoxylierte langkettige Alkohole mit 12 bis 18 C-Atomen im Alkylteil und 5 bis 15 Ethylenoxideinheiten (E0), ethoxylierte Alkylphenole mit 8 bis 10 C-Atomen im Alkylteil und 8 bis 14 Ethylenoxideinheiten, ethoxylierte Fettsäureamide mit 12 bis 18 C-Atomen im Fettsäureteil und 2 bis 8 Ethylenoxideinheiten, langkettige Aminoxide mit 14 bis 20 C-Atomen und langkettige Alkylpolyglycoside mit 8 bis 14 C-Atomen im Alkylteil und 1 bis 3 Glycosideinheiten zu erwähnen. Beispiele derartiger Tenside sind Oleyl-Cetyl-Alkohol mit 10 E0, Nonylphenol mit 10 E0, Laurinsäurediethanolamid, Kokosalkyldimethylaminoxid und Kokosalkylpolyglucosid mit im Mittel 1,4 Glucoseeinheiten. Besonders bevorzugt werden als nichtionische Tenside neben den Additionsprodukten aus Ethylenoxid und Fettalkoholen die Alkylpolyglycoside, und von diesen wiederum die Vertreter mit 8 bis 10 C-Atomen im Alkylteil und bis zu 2 Glucoseeinheiten.The nonionic surfactants are, above all, ethoxylated long-chain alcohols with 12 to 18 C atoms in the alkyl part and 5 to 15 ethylene oxide units (E0), ethoxylated alkylphenols with 8 to 10 C atoms in the alkyl part and 8 to 14 ethylene oxide units, ethoxylated fatty acid amides with 12 to 18 C atoms in the fatty acid part and 2 to 8 ethylene oxide units, long-chain amine oxides with 14 to 20 C atoms and long-chain alkyl polyglycosides with 8 to 14 C atoms in the alkyl part and 1 to 3 glycoside units. Examples of such surfactants are oleyl-cetyl alcohol with 10 E0, nonylphenol with 10 E0, lauric acid diethanolamide, Coconut alkyl dimethyl amine oxide and coconut alkyl polyglucoside with an average of 1.4 glucose units. In addition to the addition products of ethylene oxide and fatty alcohols, the alkyl polyglycosides are particularly preferred as nonionic surfactants, and of these the representatives with 8 to 10 carbon atoms in the alkyl part and up to 2 glucose units.
Eine besonders bevorzugte Kombination aus Aniontensid und nichtionischem Tensid stellt die Kombination von Fettalkylsulfat mit Alkylpolyglucosid dar, bei der ein Optimum an Benetzung und Spreitungsverhalten vorzuliegen scheint.A particularly preferred combination of anionic surfactant and nonionic surfactant is the combination of fatty alkyl sulfate with alkyl polyglucoside, in which there appears to be an optimum in wetting and spreading behavior.
Neben nichtionischen und/oder anionischen Tensiden können die erfindungsgemäß verwendeten Mittel auch kleinere Mengen von amphoteren Tensiden (Betaintensiden) enthalten. Bei diesen Tensiden handelt es sich um langkettige Verbindungen, die sowohl eine quartäre Ammoniumgruppe oder eine aminische Gruppe und eine anionische Gruppe, insbesondere ein Carboxylat- oder Sulfonatgruppe, enthalten. Beispiele derartiger Tenside sind N-Kokosalkyl-N,N-dimethylammoniumacetobetain und N-(Kokosacylamidopropyl)-N,N-dimethylammoniumacetobetain.In addition to nonionic and / or anionic surfactants, the agents used according to the invention can also contain smaller amounts of amphoteric surfactants (betaine surfactants). These surfactants are long-chain compounds which contain both a quaternary ammonium group or an amine group and an anionic group, in particular a carboxylate or sulfonate group. Examples of such surfactants are N-cocoalkyl-N, N-dimethylammoniumacetobetaine and N- (cocoacylamidopropyl) -N, N-dimethylammoniumacetobetaine.
In den erfindungsgemäß verwendeten Reinigungsmitteln werden als organische Lösungsmittel wassermischbare niedere Alkohole und/oder Etheralkohole, vorzugsweise aber Gemische aus Alkoholen und Etheralkoholen eingesetzt. Die Menge an organischem Lösungsmittel beträgt in anwendungsfertigen Reinigungsmitteln vorzugsweise 0,5 bis 15 Gew.-%, insbesondere 3 bis 10 Gew.-%, bezogen auf das fertige Reinigungsmittel. In Konzentraten kann der Gehalt an organischem Lösungsmittel entsprechend höher sein und vorzugsweise bis zu 50 Gew.-% betragen.In the cleaning agents used according to the invention, water-miscible lower alcohols and / or ether alcohols, but preferably mixtures of alcohols and ether alcohols, are used as organic solvents. The amount of organic solvent in ready-to-use cleaning agents is preferably 0.5 to 15% by weight, in particular 3 to 10% by weight, based on the finished cleaning agent. In concentrates, the organic solvent content can be correspondingly higher and preferably up to 50% by weight.
Als Alkohole werdem insbesondere Ethanol, Isopropanol und n-Propanol eingesetzt, von denen wiederum Ethanol besonders bevorzugt wird. Als Etheralkohole kommen hinreichend wasserlösliche Verbindungen mit bis zu 10 C-Atomen im Molekül in Betracht. Beispiele derartiger Etheralkohole sind Ethylenglykolmonobutylether, Propylenglykolmonobutylether, Diethylenglykolmonobutylether, Propylenglykolmonotertiärbutylether und Propylenglykolmonoethylether. Besonders bevorzugt werden im Rahmen der Erfindung Ethylenglykolmonobutylether und Propylenglykolmonobutylether.In particular, ethanol, isopropanol and n-propanol are used as alcohols, of which in turn ethanol is particularly preferred. Sufficiently water-soluble compounds with up to 10 carbon atoms in the molecule are suitable as ether alcohols. Examples of such ether alcohols are ethylene glycol monobutyl ether, propylene glycol monobutyl ether, Diethylene glycol monobutyl ether, propylene glycol mono-tertiary butyl ether and propylene glycol monoethyl ether. Ethylene glycol monobutyl ether and propylene glycol monobutyl ether are particularly preferred in the context of the invention.
Werden Alkohol und Etheralkohol nebeneinander eingesetzt, so liegt das Gewichtsverhältnis beider vorzugsweise zwischen 1 : 2 und 4 : 1.If alcohol and ether alcohol are used side by side, the weight ratio of the two is preferably between 1: 2 and 4: 1.
Wesentlich für die gute Reinigungsleistung der erfindungsgemäß verwendeten Mittel ist neben dem Gehalt an organischem Lösungsmittel der Gehalt an flüchtigem Alkali. Als solches werden Ammoniak und/oder Alkanolamine, die bis zu 9 C-Atomen im Molekül enthalten können, verwendet. Als Alkanolamine werden die Ethanolamine bevorzugt und von diesen wiederum das Monoethanolamin. Der Gehalt an Ammoniak und/oder Alkanolamin beträgt im anwendungsfertigen Reinigungsmittel vorzugsweise 0,1 bis 3 Gew.-%, insbesondere 0,2 bis 1,5 Gew.-%. In Reinigungsmittel konzentraten liegt der Gehalt entsprechend höher und kann beispielsweise 1 bis 10 Gew.-% betragen.In addition to the organic solvent content, the volatile alkali content is essential for the good cleaning performance of the agents used according to the invention. As such, ammonia and / or alkanolamines, which can contain up to 9 carbon atoms in the molecule, are used. The ethanolamines are preferred as alkanolamines, and the monoethanolamine in turn is preferred. The ammonia and / or alkanolamine content in the ready-to-use cleaning agent is preferably 0.1 to 3% by weight, in particular 0.2 to 1.5% by weight. The concentration in cleaning agent concentrates is correspondingly higher and can be, for example, 1 to 10% by weight.
Vorzugsweise enthält das erfindungsgemäß verwendete Reinigungsmittel Ammoniak und Ethanolamin, insbesondere Monoethanolamin, nebeneinander. Hier scheint bei einem Gewichtsverhältnis von Ammoniak zu Monoethanolamin zwischen etwa 1 : 2 und etwa 1 : 10 eine besonders hohe Fettentfernungswirkung aufzutreten.The cleaning agent used according to the invention preferably contains ammonia and ethanolamine, in particular monoethanolamine, side by side. A particularly high fat removal effect appears to occur here with a weight ratio of ammonia to monoethanolamine of between approximately 1: 2 and approximately 1:10.
Von entscheidender Bedeutung für die besonderen Eigenschaften der erfindungsgemäß verwendeten Mittel ist der Gehalt an Carbonsäure, wobei das Äquivalentverhältnis von Amin und/oder Ammoniak zu Carbonsäure zwischen 1 : 0,9 und 1 : 0,1 liegt. Erfindungsgemäß geeignet sind Carbonsäuren mit bis zu 6 C-Atomen, wobei es sich um Mono-, Di- oder Polycarbonsäuren handeln kann. Je nach Äquivalentgewicht von Amin- und Carbonsäure liegt der Gehalt an Carbonsäure in anwendungsfertigen Reinigungsmitteln vorzugweise zwischen 0,05 und 3 Gew.-%, insbesondere zwischen 0,05 und 1 Gew.-%. In Konzentraten liegt der Gehalt entsprechend höher und kann beispielsweise 1 bis 10 Gew.-% betragen. Durch den Zusatz der Carbonsäure wird ein Teil des ansonsten frei vorliegenden Ammoniaks bzw. Alkanolamins in die Salzform übergeführt. Dadurch sinkt der pH-Wert deutlich und kann auf Werte zurückgestellt werden, bei denen eine Beschädigung empfindlicher Oberflächen nicht mehr eintritt. Vorzugsweise werden pH-Werte im gebrauchsfertigen Mittel von etwa 9 bis etwa 10 eingestellt. Trotz dieser Rücknahme des pH-Wertes weisen die Mittel nahezu die gleiche Reinigungsleistung wie entsprechende Mittel ohne den Säurezusatz auf. Mittel, die ohne Säurezusatz mit entsprechend weniger Amin bzw. Ammoniak auf derart niedrige pH-Werte eingestellt sind, weisen wesentlich schlechtere, nicht akzeptable Reinigungsergebnisse auf.The content of carboxylic acid is of crucial importance for the special properties of the agents used according to the invention, the equivalent ratio of amine and / or ammonia to carboxylic acid being between 1: 0.9 and 1: 0.1. Carboxylic acids with up to 6 carbon atoms are suitable according to the invention, which may be mono-, di- or polycarboxylic acids. Depending on the equivalent weight of amine and carboxylic acid, the content of carboxylic acid in ready-to-use cleaning agents is preferably between 0.05 and 3% by weight, in particular between 0.05 and 1% by weight. The concentration in concentrates is correspondingly higher and can be, for example, 1 to 10% by weight. By adding the carboxylic acid, part of the otherwise freely available ammonia or alkanolamine is converted into the salt form. As a result, the pH value drops significantly and can be reset to values at which damage to sensitive surfaces no longer occurs. PH values in the ready-to-use agent are preferably adjusted from about 9 to about 10. Despite this decrease in pH, the agents have almost the same cleaning performance as corresponding agents without the addition of acid. Agents that are adjusted to such low pH values without the addition of acid with correspondingly less amine or ammonia have significantly poorer, unacceptable cleaning results.
Beispiele geeigneter Carbonsäuren sind Essigsäure, Glykolsäure, Milchsäure, Zitronensäure, Bernsteinsäure und Adipinsäure, von denen vorzugsweise Essigsäure, Zitronensäure und Milchsäure verwendet werden. Besonders bevorzugt wird Essigsäure eingesetzt.Examples of suitable carboxylic acids are acetic acid, glycolic acid, lactic acid, citric acid, succinic acid and adipic acid, of which acetic acid, citric acid and lactic acid are preferably used. Acetic acid is particularly preferably used.
Neben den Komponenten a) bis d) können die erfindungsgemäß verwendeten Mittel Hilfs- und Zusatzstoffe enthalten, wie sie in derartigen Mitteln üblich sind. Dazu zählen insbesondere Farbstoffe, Parfümöle, Konservierungsmittel, Komplexbildner für Erdalkaliionen und Viskositätsregulatoren. Die Menge an derartigen Zusätzen liegt üblicherweise nicht über 2 Gew.-% im anwendungsfertigen Reinigungsmittel. Die Untergrenze des Einsatzes hängt von der Art des Zusatzstoffes ab und kann beispielsweise bei Farbstoffen bis zu 0,001 Gew.-% und darunter betragen. Vorzugsweise liegt die Menge an Hilfsstoffen zwischen 0,01 und 1 Gew.-%. In Konzentraten kann die Menge entsprechend größer sein und beispielsweise bis zu 10 Gew.-% betragen. Im übrigen bestehen die erfindungsgemäß verwendeten Mittel aus Wasser, wobei der Wassergehalt in Konzentraten wenigstens 10 Gew.-% betragen soll.In addition to components a) to d), the agents used according to the invention can contain auxiliaries and additives as are customary in such agents. These include dyes, perfume oils, preservatives, complexing agents for alkaline earth ions and viscosity regulators. The amount of such additives is usually not more than 2% by weight in the ready-to-use cleaning agent. The lower limit of use depends on the type of additive and can be up to 0.001% by weight and below, for example in the case of dyes. The amount of auxiliaries is preferably between 0.01 and 1% by weight. In concentrates, the amount can be correspondingly larger, for example up to 10% by weight. Otherwise, the agents used according to the invention consist of water, the water content in concentrates should be at least 10% by weight.

Die Anwendung der Mittel geschieht in der Weise, daß man das anwendungsfertige Mittel in Mengen von beispielsweise etwa 1,5 bis 5 g/m2 auf die zu reinigende Fläche aufträgt und unmittelbar im Anschluß daran diese Flächen mit einem saugfähigen weichen Gegenstand wischt und sie dadurch reinigt. Der Auftrag der Mittel geschieht vorzugsweise mit Hilfe geeigneter Sprühgeräte, um eine möglichst gleichmäßige Verteilung zu erreichen. Zum Wischen eignen sich in erster Linie Schwämme oder Tücher, die bei Behandlung größerer Flächen von Zeit zu Zeit mit Wasser ausgespült werden können. Eine weitere Behandlung der Oberflächen ist nicht notwendig, da die Reinigungslösungen praktisch schleierfrei auftrocknen und selbst auf kritischen hochglänzenden Oberflächen keine Streifen hinterlassen.The agents are used in such a way that the ready-to-use agent is applied in amounts of, for example, about 1.5 to 5 g / m 2 to the surface to be cleaned and immediately afterwards these surfaces are wiped with an absorbent soft object and thereby wiped cleans. The agents are preferably applied with the aid of suitable spraying devices in order to achieve the most uniform possible distribution. Sponges or cloths are primarily suitable for wiping, which can be rinsed out with water from time to time when treating larger areas. A further treatment of the surfaces is not necessary because the cleaning solutions dry practically free of fog and do not leave streaks even on critical high-gloss surfaces.
Die Mittel 1 bis 9 wurden unmittelbar aus den Rohstoffen als verdünnte wäßrige Lösungen aufgemischt, wobei das Parfüm zunächst in den organischen Lösungsmitteln vorgelöst wurde. Als letztes wurde die Carbonsäure zugegeben.Agents 1 to 9 were mixed directly from the raw materials as dilute aqueous solutions, the perfume being first pre-dissolved in the organic solvents. The carboxylic acid was added last.
Zur Prüfung der Reinigungswirkung unter extremen Bedingungen wurden zwei verschiedene Methoden eingesetzt:
- a) An weißen PVC-Platten (40 x 554 mm), die mit einer Testanschmutzung versehen waren, wurde nach standardisierter Behandlung im Gardener-Prüfgerät die Lichtremission vermessen. Der Testschmutz hatte folgende Zusammensetzung
- 7 % feinteiliger Ruß
- 57 % Myritol (R) (Fettsäuretriglycerid)
- 36 % Testbenzin
- b) Hochglanzpolierte Bleche aus rostfreiem Stahl (40 x 554 mm) wurden mit je 0,4 g einer Mischung aus Pflanzenöl und Testbenzin (1 : 1) gleichmäßig bestrichen und nach dem Abdunsten des Lösungsmittels 15 Stunden bei 80 °C an der Luft gelagert. Die Reinigung der Bleche erfolgte dann wie unter a) angegeben, während die Beurteilung der Reinigungswirkung visuell im Vergleich zu einem ungereinigten und einem nicht angeschmutzten Blech vorgenommen wurde. Folgende Bewertungsnoten wurden verwendet:
- 1 = Fett vollständig entfernt
- 2 = Fett weitgehend entfernt
- 3 = Fett teilweise entfernt
- 4 = Fett nur zu einem geringen Teil entfernt
- 5 = Fett nahezu unverändert
Die Ergebnisse sind ebenfalls in der Tabelle angeführt.
Aus den Ergebnissen wird deutlich, daß mit den erfindungsgemäß verwendeten Beispielen 2, 3 und 7 nahezu das gleiche Reinigungsergebnis zu erzielen ist, wie mit den Mitteln, die bei gleicher Alkalikonzentration keinen Säurezusatz aufweisen (1,6). Gleichzeitig ist die erheblich verbesserte Reinigungsleistung gegenüber den Mitteln ohne Alkalizusatz oder mit nur geringem Alkalizusatz (4, 5, 8, 9) zu erkennen (Der pH-Wert in den Mitteln 4 und 8 erklärt sich aus Alkalispuren in den Tensidrohstoffen).
- a) The light remission was measured on white PVC sheets (40 x 554 mm), which were provided with test soiling, after standardized treatment in the Gardener test device. The test dirt had the following composition
- 7% fine soot
- 57% myritol (R) (fatty acid triglyceride)
- 36% white spirit
- b) Highly polished sheets of stainless steel (40 x 554 mm) were evenly coated with 0.4 g of a mixture of vegetable oil and white spirit (1: 1) and stored in air at 80 ° C for 15 hours after the solvent had evaporated. The sheets were then cleaned as stated under a), while the cleaning effect was assessed visually in comparison with an unpurified and an unpolluted sheet. The following evaluation grades were used:
- 1 = fat completely removed
- 2 = fat largely removed
- 3 = fat partially removed
- 4 = only a small part of the fat removed
- 5 = fat almost unchanged
The results are also shown in the table.
It is clear from the results that with Examples 2, 3 and 7 used according to the invention almost the same cleaning result can be achieved as with the agents which have no added acid at the same alkali concentration (1.6). At the same time, the significantly improved cleaning performance compared to agents without added alkali or with only a small amount of alkali (4, 5, 8, 9) can be seen (the pH value in agents 4 and 8 is explained by traces of alkali in the surfactant raw materials).
