The surfactant solution contains a combination of alkyl polyglycoside and alkylether sulphate. This process achieves remarkable cleaning results without leaving visible residues on the floor.

Description

Die vorliegende Erfindung liegt auf dem Gebiet der Reinigung von Fußböden mit Hilfe wäßriger Tensidlösungen.The present invention is in the field of cleaning floors using aqueous surfactant solutions.

Die heute gebräuchlichsten Verfahren zur Reinigung und Pflege von Fußböden lassen sich im wesentlichen in drei Klassen einteilen:Today's most common methods of cleaning and maintaining floors can be divided into three classes:

Verfahren, die in erster Linie die Pflege und Konservierung der Fußböden zum Ziel haben, verwenden Mittel, die nach dem Auftragen und Verteilen auf den Fußbodenoberflächen mehr oder weniger harte widerstandsfähige Schutzfilme erzeugen. Die Mittel enthalten zu diesem Zweck, meist in emulgierter Form, Wachse oder filmbildende Polymere und vernetzende Wirkstoffe, in der Regel Schwermetallsalze, die zusammen nach dem Abtrocknen auf den behandelten Flächen selbstglänzende oder polierbare Filme bilden. Auf diese Weise läßt sich eine langanhaltende Konservierung der Oberflächen erreichen, wobei je nach Qualität des Films auch starke mechanische Beanspruchungen gut vertragen werden. Nachteilig ist bei diesen Mitteln, daß eine Entfernung der festhaftenden Filme, wenn sie, etwa wegen Verschmutzung oder Beschädigung, notwendig wird, nur unter extremen Bedingungen möglich ist.Processes that primarily aim to care for and preserve the flooring use agents that, after being applied and distributed on the flooring surfaces, produce more or less hard, protective films. For this purpose, the agents usually contain heavy metal salts, mostly in emulsified form, waxes or film-forming polymers and crosslinking agents, which together form self-glossy or polishable films on the treated surfaces after drying. In this way, long-lasting preservation of the surfaces can be achieved, with strong mechanical loads being well tolerated, depending on the quality of the film. A disadvantage of these agents is that removal of the firmly adhering films, if it becomes necessary, for example because of dirt or damage, is only possible under extreme conditions.

Im Gegensatz dazu verwendet man bei Verfahren, deren Ziel die Reinigung und Wiederherstellung der ursprünglichen Oberfläche ist, Mittel die hohe Anteile an Tensiden, oft zusammen mit alkalisch reagierenden Stoffen, organischen Lösungsmitteln oder Abrasivstoffen enthalten. Mit diesen Mitteln ist in vielen Fällen eine gründliche Entfernung von Verschmutzungen und alten Belägen möglich, doch sind die so gereinigten Oberflächen danach in der Regel der Wiederanschmutzung schutzlos ausgesetzt, sofern nicht eine Konservierungsbehandlung angeschlossen wird.In contrast, in processes whose aim is to clean and restore the original surface, agents are used which contain high amounts of surfactants, often together with alkaline substances, organic solvents or abrasives. In many cases, these agents can be used to thoroughly remove dirt and old coverings, but the surfaces cleaned in this way are usually exposed to re-soiling without protection, unless a preservation treatment is connected.

Neben diesem Verfahren der Grundreinigung, bei dem die alten Selbstglanzbeläge entfernt werden, kennt man Verfahren zur oberflächlichen Reinigung, bei dem nur lose aufliegender und anhaftender Schmutz entfernt wird, ohne daß es zu einem Angriff auf die Pflegefilme kommt. Die dabei verwendeten Mittel enthalten Tenside nur in geringer Konzentration und allenfalls geringe Mengen an Alkali. Meist sind gleichzeitig geringe Konzentrationen an pflegenden Substanzen enthalten, weshalb diese Mittel auch als Wischpflegemittel bezeichnet werden. Ein Beispiel eines solchen Mittels wird in der japanischen Patentanmeldung 3/182596 beschrieben.In addition to this process of basic cleaning, in which the old self-gloss coverings are removed, processes are known for superficial cleaning, in which only loosely lying and adhering dirt is removed without the care films being attacked. The agents used contain surfactants only in low concentrations and at most small amounts of alkali. Usually, low concentrations of nourishing substances are contained at the same time, which is why these agents are also referred to as wiping agents. An example of such an agent is described in Japanese Patent Application 3/182596.

Bei den zuletzt genannten Verfahren, zu denen auch das Verfahren gemäß der vorliegenden Erfindung gehört, liegt ein wesentliches Problem darin, bei guter Schmutzentfernung die sonstigen Eigenschaften der Fußbodenoberfläche, insbesondere deren Glanz, nicht zu beeinträchtigen. Dieses Problem ist bei den heute angewandten Verfahren vielfach nur mangelhaft gelöst, weil die verwendeten Reinigungsmittel nicht gleichmäßig genug verteilt werden können und streifenförmig auftrocknen. Es bestand daher trotz vieler Vorschläge auf diesem Gebiet nach wie vor die Aufgabe, ein insgesamt befriedigenderes Verfahren zu entwickeln.With the last-mentioned methods, which also includes the method according to the present invention, a major problem lies in not impairing the other properties of the floor surface, in particular its gloss, with good dirt removal. This problem is often only poorly solved in the processes used today because the cleaning agents used cannot be distributed evenly enough and dry up in strips. In spite of many suggestions in this area, there was therefore still the task of developing an overall more satisfactory process.

Die vorliegende Erfindung bietet eine Lösung dieses Problems in Form eines Verfahrens zur Reinigung von Fußböden, bei dem eine wäßrige Tensidlösung in einer Menge von 0,2 bis 5 g pro Quadratmeter unverdünnt auf den Fußboden, vorzugsweise durch Sprühen, aufgetragen und dort durch Wischen verteilt wird, wobei diese Lösung eine Tensidkombination aus Alkylpolyglycosid und Alkylethersulfat enthält.The present invention offers a solution to this problem in the form of a method for cleaning floors, in which an aqueous surfactant solution in an amount of 0.2 to 5 g per square meter is applied undiluted to the floor, preferably by spraying, and is distributed there by wiping , wherein this solution contains a surfactant combination of alkyl polyglycoside and alkyl ether sulfate.

Durch den Vorgang des Aufsprühens und insbesondere das anschließende Wischen des Fußbodens wird eine weitgehend gleichmäßige Verteilung des Reinigungsmittels erreicht, so daß dessen Wirkung sich gleichmäßig entfalten kann. Der nach dem Wischen auf dem Fußboden verbleibende Anteil der Tensidlösung trocknet in bisher unerreichter Weise so gleichmäßig auf die Fußbodenoberfläche auf, daß keine Streifen erkennbar sind und der Glanz der Oberfläche voll erhalten bleibt. Die hohe Reinigungswirkung und die Eigenschaft des streifenfreien Auftrocknens werden entscheidend durch die in der Lösung vorliegende Tensidkombination aus Alkylpolyglycosid und Alkylethersulfat bestimmt. Bei den erfindungsgemäß verwendeten Alkylpolyglycosiden handelt es sich um Tenside der allgemeinen Formel I

        R-O(-G)n     I

in der R einen langkettigen Alkylrest mit 8 bis 22 C-Atomen, G einen glycosidisch gebundenen Rest eines Monosaccharids und n einen Wert zwischen 1 und 10 bedeuten.The process of spraying and in particular the subsequent wiping of the floor results in a largely uniform distribution of the cleaning agent, so that its effect can develop evenly. The portion of the surfactant solution remaining on the floor after wiping dries on the floor surface so uniformly in an unprecedented manner that no streaks can be seen and the surface gloss remains intact. The high cleaning effect and the property of streak-free drying are decisively determined by the surfactant combination of alkyl polyglycoside and alkyl ether sulfate present in the solution. The alkyl polyglycosides used according to the invention are surfactants of the general formula I.

RO (-G) n I

in which R is a long-chain alkyl radical having 8 to 22 carbon atoms, G is a glycosidically bonded radical of a monosaccharide and n is a value between 1 and 10.

Alkylpolyglycoside sind als oberflächenaktive Substanzen seit mehr als 50 Jahren bekannt und können auf verschiedenen Wegen hergestellt werden. In diesem Zusammenhang sei nur auf die europäische Patentanmeldung 362 671 hingewiesen, in der auch Literatur zu älteren Verfahren zitiert wird.Alkyl polyglycosides have been known as surface-active substances for more than 50 years and can be produced in various ways. In this context, reference should only be made to European patent application 362 671, which also cites literature on older processes.

Eine für den technischen Maßstab heute bedeutsame Synthese besteht im wesentlichen in der säurekatalysierten Kondensation von Monosacchariden vom Typ der Aldosen (HO-G) mit langkettigen Alkoholen (R-OH), die 8 bis 22, vorzugsweise 8 bis 18 C-Atome enthalten. Unter Wasseraustritt entstehen Alkylglycoside der Formel I

        R-O(-G)n

wobei der Wert von n durch die Wahl der Reaktionsbedingungen in weiten Grenzen variiert werden kann. Erfindungsgemäß brauchbar sind Alkylglycoside der Formel I mit n = 1 bis 10; bevorzugt werden Verbindungen mit Werten für n zwischen 1 und 6, inbesondere 1 bis 2. In Produkten, bei denen n größer als 1 ist, stellt n naturgemäß einen statistischen Mittelwert dar.A synthesis which is important on an industrial scale today consists essentially in the acid-catalyzed condensation of monosaccharides of the aldose type (HO-G) with long-chain alcohols (R-OH) which contain 8 to 22, preferably 8 to 18, C atoms. When water escapes, alkyl glycosides of the formula I are formed

RO (-G) n

the value of n can be varied within wide limits by the choice of reaction conditions. Alkyl glycosides of the formula I with n = 1 to 10 can be used according to the invention; Compounds with values for n between 1 and 6, in particular 1 to 2, are preferred. In products in which n is greater than 1, n naturally represents a statistical mean.

Bei der Herstellung der Alkylglycoside kann man auch von Oligo- oder Polysacchariden ausgehen, die dann im Verlauf der säurekatalysierten Reaktion zunächst durch Hydrolyse und/oder Alkoholyse zu niederen Bruchstücken depolymerisiert werden ehe sich die Alkylglycoside der Formel I bilden. Auch Gemische verschiedener reduzierender Monosaccharide oder Polysaccharide, die verschiedene Monosaccharideinheiten enthalten, lassen sich als Ausgangsmaterialien verwenden, wobei, falls n größer als 1 ist, entsprechend gemischt zusammengesetzte Alkylglycosidmoleküle entstehen können.In the production of the alkyl glycosides, one can also start from oligosaccharides or polysaccharides, which are then depolymerized to lower fragments in the course of the acid-catalyzed reaction by hydrolysis and / or alcoholysis before the alkyl glycosides of the formula I form. Mixtures of different reducing monosaccharides or polysaccharides which contain different monosaccharide units can also be used as starting materials, and if n is greater than 1, appropriately mixed alkylglycoside molecules can be formed.

Als Ausgangsmaterialien eignen sich vorzugsweise folgende Monosaccharide: Glucose, Mannose, Galaktose, Arabinose, Apiose, Lyxose, Gallose, Altrose, Idose, Ribose, Xylose und Talose sowie die aus diesen Monosacchariden zusammengesetzten Oligo- und Polysaccharide, beispielsweise Maltose, Lactose, Maltotriose, Hemicellulose, Stärke, Partialhydrolisate der Stärke und Zuckersirup. Im Rahmen der Erfindung werden allerdings Alkylglycoside bevorzugt, die aus gleichen Monosaccharideinheiten aufgebaut sind. Besonders bevorzugt werden dabei Alkylglycoside, bei denen der Rest (-G) von der Glucose abgeleitet ist. Für diese auch als Alkylglucoside bezeichneten Verbindungen werden entsprechend als Ausgangsmaterialien Glucose, Maltose, Stärke und andere Oligomere der Glucose verwendet.The following monosaccharides are preferably suitable as starting materials: glucose, mannose, galactose, arabinose, apiose, lyxose, gallose, old rose, Idose, ribose, xylose and talose, and the oligosaccharides and polysaccharides composed of these monosaccharides, for example maltose, lactose, maltotriose, hemicellulose, starch, partial hydrolysates of starch and sugar syrup. In the context of the invention, however, alkyl glycosides are preferred which are composed of the same monosaccharide units. Alkyl glycosides in which the rest (-G) is derived from glucose are particularly preferred. For these compounds, which are also referred to as alkyl glucosides, glucose, maltose, starch and other oligomers of glucose are used accordingly as starting materials.

Der Alkylteil R leitet sich bei der oben beschriebenen Herstellung von langkettigen, gegebenenfalls ungesättigten, vorzugsweise primären Alkoholen ab, die verzweigt sein können, vorzugsweise aber nicht verzweigt sind. Beispiele sind die synthetischen Oxoalkohole mit 9 bis 15 C-Atomen und die aus natürlichen Fettsäuren gewonnenen Fettalkohole mit 8 - 22 C-Atomen. Bevorzugt werden die Fettalkohole mit 8 bis 18 C-Atomen sowie die Oxoalkohole mit 11 bis 15 C-Atomen, insbesondere aber die Fettalkohole mit 8 bis 10 C-Atomen oder mit 12 bis 14 C-Atomen.In the preparation described above, the alkyl part R is derived from long-chain, optionally unsaturated, preferably primary alcohols which can be branched, but are preferably not branched. Examples are the synthetic oxo alcohols with 9 to 15 C atoms and the fatty alcohols obtained from natural fatty acids with 8 - 22 C atoms. The fatty alcohols with 8 to 18 carbon atoms and the oxo alcohols with 11 to 15 carbon atoms are preferred, but in particular the fatty alcohols with 8 to 10 carbon atoms or with 12 to 14 carbon atoms.

Neben den eigentlichen Alkylglykosiden der Formel I enthalten technisch hergestellte Produkte im allgemeinen noch gewisse Anteile an freiem Alkohol R-OH und nicht acetalisierte Saccharide, gegebenenfalls in oligomerisierter Form. Diese technischen Verunreinigungen stören in den meisten Fällen beim beabsichtigten Verwendungszweck nicht. Wird bei der Herstellung der Alkylglykoside von Alkoholgemischen ausgegangen, beispielsweise von Alkoholen auf Basis natürlicher Fette, handelt es sich selbstverständlich auch bei den Alkylglykosiden um Gemische mit entsprechend weiter Bedeutung von R in der Formel I.In addition to the actual alkyl glycosides of formula I, technically manufactured products generally also contain certain proportions of free alcohol R-OH and non-acetalized saccharides, optionally in oligomerized form. In most cases, these technical impurities do not interfere with the intended use. If alcohol mixtures are used in the production of the alkyl glycosides, for example alcohols based on natural fats, the alkyl glycosides are of course also mixtures with a correspondingly larger meaning of R in formula I.

Bei der zweiten im erfindungsgemäßen Tensidgemisch verwendeten Komponente handelt es sich um Alkylethersulfate. Chemisch gesehen sind dies Salze von Schwefelsäuremonoestern ethoxylierter langkettiger Alkohole mit der allgemeinen Formel II

        R'-O(-CH2-CH2-O)m-SO4M     II

Alkylethersulfate sind als Tenside seit langer Zeit im praktischen Gebrauch, so daß auf die Herstellung an dieser Stelle nicht näher eingegangen werden muß. Ein übliches Verfahren ist die Ethoxylierung langkettiger Alkohole R-OH mit m Mol Ethylenoxid und anschließende Sulfatierung und Neutralisierung. In Formel II leitet sich der Rest R' von langkettigen, gegebenenfalls ungesättigten, vorzugsweise primären Alkoholen ab, die verzweigt sein können, vorzugsweise aber nicht verzweigt sind. Beispiele sind die synthetischen Oxoalkohole mit 9 bis 15 C-Atomen und die aus natürlichen Fettsäuren gewonnen Fettalkohole mit 8 bis 22 C-Atomen. Bevorzugt werden im Rahmen der Erfindung Ethersulfate, bei denen sich R' von Fettalkoholen mit 10 bis 18 C-Atomen oder von Oxoalkoholen mit 11 bis 15 C-Atomen ableitet. Der Index m gibt die Anzahl der Mole Ethylenoxid (EO) an, die im Molekül gebunden sind. Der Wert für m liegt bei den erfindungsgemäß verwendbaren Ethersulfaten zwischen 1 und 6, vorzugsweise zwischen 2 und 4. Es ist bei dem üblichen Herstellungsverfahren, das über die Ethoxylierung von langkettigen Alkoholen R'-OH verläuft, selbstverständlich, daß m stets nur einen Mittelwert mehrerer ganzer Zahlen bedeuten kann. M stellt das Kation der zur Neutralisation des Schwefelsäurehalbesters verwendeten Base dar. Bei den erfindungsgemäß verwendbaren Alkylethersulfaten ist M vorzugsweise Alkalimetall oder Ammonium, insbesondere Natrium.The second component used in the surfactant mixture according to the invention is alkyl ether sulfate. Chemically speaking, these are salts of sulfuric acid monoesters of ethoxylated long-chain alcohols with the general formula II

R'-O (-CH 2 -CH 2 -O) m -SO 4 M II

Alkyl ether sulfates have long been in practical use as surfactants, so that the preparation need not be discussed in more detail here. A common method is the ethoxylation of long-chain alcohols R-OH with m mol of ethylene oxide and subsequent sulfation and neutralization. In formula II, the radical R 'is derived from long-chain, optionally unsaturated, preferably primary alcohols which can be branched, but are preferably not branched. Examples are the synthetic oxo alcohols with 9 to 15 carbon atoms and the fatty alcohols with 8 to 22 carbon atoms obtained from natural fatty acids. Preferred within the scope of the invention are ether sulfates in which R 'is derived from fatty alcohols with 10 to 18 C atoms or from oxo alcohols with 11 to 15 C atoms. The index m indicates the number of moles of ethylene oxide (EO) that are bound in the molecule. The value for m in the ether sulfates which can be used according to the invention is between 1 and 6, preferably between 2 and 4. In the conventional production process which proceeds via the ethoxylation of long-chain alcohols R'-OH, it goes without saying that m is always only an average of several integers can mean. M represents the cation of the base used to neutralize the sulfuric acid half-ester. In the alkyl ether sulfates which can be used according to the invention, M is preferably alkali metal or ammonium, in particular sodium.

Die besonderen Vorzüge des erfindungsgemäßen Reiniungsverfahrens beruhen ganz wesentlich auf der gleichzeitigen Verwendung der Alkylpolyglycoside und Alkylethersulfate in der wäßrigen Reinigungsflotte. Üblicherweise liegt das Gewichtsverhältnis zwischen Alkylpolyglycosiden und Alkylethersulfaten zwischen etwa 1 : 10 und 10 : 1. Bevorzugt werden Gewichtsverhältnisse zwischen 4 : 1 und 1 : 4 und insbesondere zwischen 2 : 1 und 1 : 2. Auf Grund des besonderen Zusammenwirkens dieser Tenside ist in der Reinigungslösung nur eine geringe Konzentration des Tensidgemisches erforderlich, die vorzugsweise 0,2 bis 4 Gewichtsprozent und insbesondere 0,5 bis 2 Gewichtsprozent beträgt.The particular advantages of the cleaning process according to the invention are based to a very large extent on the simultaneous use of the alkyl polyglycosides and alkyl ether sulfates in the aqueous cleaning liquor. The weight ratio between alkyl polyglycosides and alkyl ether sulfates is usually between about 1:10 and 10: 1. Weight ratios between 4: 1 and 1: 4 and in particular between 2: 1 and 1: 2 are preferred. Due to the particular interaction of these surfactants, the Cleaning solution required only a low concentration of the surfactant mixture, which is preferably 0.2 to 4 percent by weight and in particular 0.5 to 2 percent by weight.

Neben der erfindungsgemäß verwendeten Tensidkombination enthält die Reinigungslösung üblicherweise keine anderen Tenside, wenn auch deren Anwesenheit nicht ausgeschlossen ist, sofern sie die vorteilhafte Wirkung des Gemisches aus Alkylpolyglycosiden und Alkylethersulfaten nicht stört. Dagegen kann der Zusatz anderer Reinigungswirkstoffe und Pflegemittel zweckmäßig sein. Zu erwähnen sind hier in erster Linie wassermischbare organische Lösungsmittel, Komplexbildner für die Wasserhärte, Wachse und filmbildende Polymere. Daneben seien Farbstoffe, Duftstoffe, Schauminhibitoren und antimikrobielle Wirkstoffe sowie Säuren und Basen zur Regulierung des pH-Wertes genannt. Es ist selbstverständlich, daß bei der Auswahl nur solche Vertreter dieser Stoffe gewählt werden, die die vorteilhaften Wirkungen des Tensidgemisches aus Alkylpolyglycosiden und Alkylethersulfaten nicht beeinträchtigen.In addition to the surfactant combination used according to the invention, the cleaning solution usually does not contain any other surfactants, albeit their Presence is not excluded, provided that it does not interfere with the advantageous effect of the mixture of alkyl polyglycosides and alkyl ether sulfates. In contrast, the addition of other cleaning agents and care products can be useful. First of all, water-miscible organic solvents, complexing agents for water hardness, waxes and film-forming polymers should be mentioned. In addition, dyes, fragrances, foam inhibitors and antimicrobial agents as well as acids and bases for regulating the pH are mentioned. It goes without saying that only representatives of these substances are selected in the selection which do not impair the advantageous effects of the surfactant mixture of alkyl polyglycosides and alkyl ether sulfates.

Bei den erfindungsgemäß verwendbaren wassermischbaren organischen Lösungsmitteln handelt es sich in erster Linie um leicht flüchtige Alkohole und Etheralkohole. Beispiele sind insbesondere die niederen Alkohole mit 2 bis 4 C-Atomen, von denen wiederum Ethanol besonders bevorzugt wird. Der Gehalt an organischen Lösungsmitteln in der Reinigungsmittellösung liegt im allgemeinen nicht über 20 Gewichtsprozent, vorzugsweise zwischen 1 und 10 Gewichtsprozent.The water-miscible organic solvents which can be used according to the invention are primarily volatile alcohols and ether alcohols. Examples are in particular the lower alcohols with 2 to 4 carbon atoms, of which ethanol is particularly preferred. The content of organic solvents in the cleaning agent solution is generally not more than 20 percent by weight, preferably between 1 and 10 percent by weight.

Die Mitverwendung von Wachsen und/oder filmbildenden Polymeren in der Reinigungsmittellösung hat den Zweck, den auf der Fußbodenoberfläche zurückbleibenden dünnen Film stärker schmutzabweisend auszurüsten und gegebenenfalls geringfügige Beschädigungen in der Oberfläche des Fußbodens, die den Glanz beeinträchtigen, auszugleichen. Als Wachse eignen sich sowohl synthetische Wachse, wie beispielsweise Polyethylenwachse, teilsynthetische Wachse, wie die Montanesterwachse und na-türliche Wachse, wie beispielsweise Carnaubawachs und Candelilawachs. Erfindungsemäß bevorzugt werden die natürlichen Wachse, insbesondere Carnaubawachs. Die Konzentration der Wachse in der Reinigungslösung liegt überlicherweise nicht über etwa 0,3 Gewichtsprozent, vorzugsweise zwischen 0,05 und 0,2 Gewichtsprozent. Als Polymere eignen sich generell alle in Wasser im schwach alkalischen Bereich löslichen Polymerverbindungen, die aus Lösungen unter Filmbildung auftrocknen. In der Regel handelt es sich dabei um Copolymerisate mit einem gewissen Anteil an carbonsäuregruppenhaltigen Monomeren, insbesondere Acrylsäure oder Methacrylsäure, die außerdem nichtionische Monomere, insbesondere aus der Gruppe der Acrylsäure- oder Methacrylsäureester mit niederen Alkoholen und Styrol enthalten. Auch der Gehalt an Polymeren in den Reinigungsmittel lösungen liegt üblicherweise nicht über 0,3 Gewichtsprozent, vorzugsweise zwischen 0,05 und 0,2 Gewichtsprozent. Polymere Filmbildner und Wachse können auch gleichzeitig anwesend sein.The use of waxes and / or film-forming polymers in the cleaning agent solution has the purpose of making the thin film remaining on the floor surface more dirt-repellent and, if necessary, to compensate for minor damage to the surface of the floor which impair the gloss. Suitable waxes are both synthetic waxes, such as polyethylene waxes, partially synthetic waxes, such as montan ester waxes, and natural waxes, such as carnauba wax and candelilla wax. According to the invention, natural waxes, in particular carnauba wax, are preferred. The concentration of the waxes in the cleaning solution is usually not more than about 0.3 percent by weight, preferably between 0.05 and 0.2 percent by weight. Suitable polymers are generally all polymer compounds which are soluble in water in the weakly alkaline range and which dry out from solutions with the formation of a film. As a rule, these are copolymers with a certain proportion of monomers containing carboxylic acid groups, in particular acrylic acid or methacrylic acid, which also contain nonionic monomers, in particular from the group of acrylic acid or methacrylic acid esters with lower alcohols and styrene. The content of polymers in the cleaning agent solutions is usually not more than 0.3 percent by weight, preferably between 0.05 and 0.2 percent by weight. Polymeric film formers and waxes can also be present at the same time.

Zur Durchführung des erfindungsgemäßen Verfahrens wird die vorstehend geschilderte Reinigungsmittel lösung in möglichst gleichmäßiger Form auf den zu behandelnden Fußboden aufgetragen und unmittelbar anschließend durch Wischen auf dem Boden verteilt. Das Auftragen geschieht in besonders vorteilhafter Weise durch Aufsprühen entweder mit Hilfe kleiner Handsprühgeräte oder aber, vor allem im gewerblichen Bereich, mit Hilfe maschineller Sprühvorrichtungen. Die aufzutragende Menge richtet sich in gewissen Grenzen nach dem Verschmutzungsgrad des Bodens und seiner Oberflächenrauhigkeit. Sie liegt erfindungsgemäß im Bereich zwischen 0,2 g und 5 g/m2 und insbesondere zwischen etwa 0,3 und 2 g/m2. Das Wischen erfolgt vorzugsweise mit einem angefeuchteten saugfähigen weichen Gegenstand, insbesondere mit einem Tuch, einem Schwamm oder einem Mop. Während des Wischens wird einerseits die Reinigungsmittellösung gleichmäßig über die gesamte Fläche verteilt, andererseits der angelöste Schmutz zusammen mit überschüssiger Reinigungsmittel lösung von dem saugfähigen Gegenstand aufgenommen. Der saugfähige Gegenstand wird von Zeit zu Zeit in klarem Wasser ausgespült, wobei der aufgenommene Schmutz und überschüssige Tensidlösung abgegeben werden. Größere Flächen können abschnittweise gereinigt werden, um zu verhindern, daß die aufgesprühte Reinigungsmittellösung zu stark antrocknet. Neben hervorragender Reinigungswirkung und der Vermeidung von Streifenbildung auf den Oberflächen zeichnet sich das erfindungsgemäße Verfahren auch noch durch ökologische Vorteile aus. Durch die Applikation der Reinigungsmittel lösung direkt auf die zu reinigende Fußbodenoberfläche wird immer nur die für die Reinigung notwendige Mindestmenge eingesetzt, während bei der herkömmlichen Wischreinigung das Reinigungsmittel in den Wassereimer verdünnt wurde, so daß immer ein großer Anteil ungenutzt mit dem Wischwasser in die Kanalisation gelangte.To carry out the method according to the invention, the cleaning agent solution described above is applied in as uniform a form as possible to the floor to be treated and is then immediately distributed by wiping on the floor. The application takes place in a particularly advantageous manner by spraying either with the aid of small hand-held sprayers or, particularly in the commercial sector, with the aid of mechanical spraying devices. The amount to be applied depends within certain limits on the degree of soiling of the floor and its surface roughness. According to the invention, it lies in the range between 0.2 g and 5 g / m 2 and in particular between approximately 0.3 and 2 g / m 2 . The wiping is preferably carried out with a damp, absorbent soft object, in particular with a cloth, a sponge or a mop. While wiping the detergent solution is evenly distributed over the entire surface, on the other hand the loosened dirt together with excess detergent solution is absorbed by the absorbent object. From time to time, the absorbent article is rinsed out in clear water, the absorbed dirt and excess surfactant solution being released. Larger areas can be cleaned in sections to prevent the sprayed-on cleaning solution from drying too much. In addition to excellent cleaning action and the avoidance of streaking on the surfaces, the method according to the invention is also distinguished by ecological advantages. By applying the detergent solution directly to the surface of the floor to be cleaned, only the minimum amount necessary for cleaning is used, whereas with conventional wiping cleaning, the detergent was diluted in the water bucket, so that a large proportion of the wiping water always reached the sewage system unused .

  • 1. Rückstandsverhalten
    Ein Fußbodenstück der Größe 75 x 60 cm, das mit schwarzen hochglänzenden Kacheln belegt war, wurde zur Hälfte mit dem Reinigungsmittel behandelt und nach dem Abtrocknen visuell durch drei Prüfer abgemustert. Zur Durchführung des Reinigungsverfahrens wurden auf die zu behandelnde Hälfte des Fußbodenstückes mit einer Glaspipette 0,2 ml des jeweiligen Reinigungsmittels aufgebracht und dieses Mittel mit einem feuchten, gut ausgewrungenen Baumwolltuch (25 x 25 cm) durch Wischen gleichmäßig verteilt. Dieser Vorgang wurde, um eine Akkumulation des Reinigungsmittels beobachten zu können, nach Zwischentrocknung des verbleibenden feuchten Reinigungsmittels viermal mit einem frischausgespülten Tuch wiederholt. Nach dem Antrocknen des letzten Auftrags wurde die Bewertung durchgeführt, wobei nach Absprache der Prüfer folgende Bewertungsziffern vergeben wurden:
    1 =
    kein sichtbarer Unterschied zwischen behandelter und nichtbehandelter Fläche
    2 =
    leichte Streifenbildung
    3 =
    stärkere Streifenbildung
    4 =
    deutlicher, flächig sichtbarer Rückstand
  • 1a. Rückstandsverhalten bei Anwendung der Mittel im herkömmlichen Reinigungsverfahren (Wassereimer-Methode)
    In einem Wassereimer wurde eine Mischflotte dadurch hergestellt, daß 10 g der jeweiligen Mittel pro Liter Leitungswasser (Wasserhärte 25°d) aufgelöst wurden. Mit dieser Lösung wurde ein Baumwolltuch der Größe 25 x 25 cm getränkt und dann das tropfnasse Baumwolltuch zum Wischen der unter 1. beschriebenen Fläche benutzt. Das Tuch wurde dann ausgewrungen und die Fläche einmal mit diesem Tuch nachgewischt. Wie unter 1. angegeben wurde der Wischvorgang jeweils nach dem Abtrocknen der Fläche viermal wiederholt. Die visuelle Bewertung entspricht der unter 1.
  • 2. Reinigungsvermögen nach Gardner (nicht erfindungsgemäß)
    Die Prüfung erfolgte in der für Wischpflegemittel in der Zeitschrift "Seifen-Öle-Fette-Wachse" 1986 S. 371-72 angegebenen Weise an weißen, künstlich angeschmutzten PVC-Platten der Größe 40 x 554 mm. Als Anschmutzung diente das dort angegebene Gemisch aus 7% Ruß, 57% Fettsäuretriglycerid und 36% Benzin. Es wurde in Variante a auf unbehandelte PVC Streifen aufgetragen, während in Variante b PVC-Streifen angeschmutzt wurden, die mit dem Reinigungsmitteln vorbehandelt worden waren. Diese Vorbehandlung, die zur Überprüfung eines schmutzabweisenden Effektes vorgenommen wurde, geschah in der Weise, daß die Fläche von 7 eng nebeneinander liegenden Streifen mit einer Gesamtfläche von 280 x 554 mm mit 5 ml des jeweiligen Reinigungsmittels versehen und dann mit einem feuchten Baumwollappen (25 x 25 cm) gleichmäßig gewischt wurde. Nach dem Abtrocknen wurde diese Behandlung noch zweimal wiederholt, ehe dann die Anschmutzung aufgetragen wurde.
The cleaning effect and residue behavior were tested on the following agents 1 and 2 according to the invention and in the same way also on agents 3 to 6 not according to the invention. The composition of the agents is shown in Table 1 (data in percent by weight). Table 1 ingredients Examples 1 2nd 3rd 4th 5 6 Ethanol 5.0 5.0 5.0 C 12 -C 14 fatty alcohol sulfate Na 0.58 C 12 -C 14 fatty alcohol ether sulfate Na (2 EO) 0.5 0.5 0.5 Coconut alcohol ethoxylate (4 EO) 0.5 0.5 sec.

  • 1. Residue behavior
    A 75 x 60 cm piece of flooring with black high-gloss finish Tiles were covered, half was treated with the cleaning agent and visually checked by three inspectors after drying. To carry out the cleaning process, 0.2 ml of the respective cleaning agent was applied to the half of the floor piece to be treated with a glass pipette and this agent was evenly distributed with a damp, well wrung out cotton cloth (25 x 25 cm). In order to be able to observe an accumulation of the cleaning agent, this process was repeated four times with a freshly rinsed cloth after the remaining moist cleaning agent had dried. After the last order had dried on, the evaluation was carried out, with the following evaluation numbers being assigned after the examiners' agreement:
    1 =
    no visible difference between treated and untreated surfaces
    2 =
    slight streaking
    3 =
    stronger banding
    4 =
    clear, area-visible residue
  • 1a. Residue behavior when using the agents in the conventional cleaning process (water bucket method)
    A mixing liquor was prepared in a water bucket by dissolving 10 g of the respective agent per liter of tap water (water hardness 25 ° d). A 25 x 25 cm cotton cloth was impregnated with this solution and the dripping wet cotton cloth was then used to wipe the area described under 1. The cloth was then wrung out and the surface wiped once with this cloth. As stated under 1., the wiping process was repeated four times each time the surface had dried. The visual assessment corresponds to that under 1.
  • 2. Gardner cleaning power (not according to the invention)
    The test was carried out in the manner specified for wiping agents in the magazine "Seifen-Öle-Fette-Wwachs" 1986 pp. 371-72 on white, artificially soiled PVC sheets of size 40 x 554 mm. As soiling served the mixture of 7% carbon black, 57% fatty acid triglyceride and 36% gasoline specified there. In variant a, it was applied to untreated PVC strips, while in variant b PVC strips that had been pretreated with the cleaning agent were soiled. This pretreatment, which was carried out to check a dirt-repellent effect, was carried out in such a way that the area of 7 strips lying closely next to one another with a total area of 280 x 554 mm was given 5 ml of the respective cleaning agent and then with a damp cotton cloth (25 x 25 cm) was wiped evenly. After drying, this treatment was repeated two more times before the soiling was applied.

Im eigentlichen Reinigungsgang, der mit einem mechanisch betriebenen Schwamm durchgeführt wurde, betrug die Menge an Reinigungsmittel 6 ml pro Streifen. Die Auswertung von 7 jeweils gleichartig behandelten Streifen erfolgte mit einem Lange Farbdifferenz-Meßgerät Microcolor, das die Ergebnisse in Prozent Reinigungswirkung (bezogen auf die weiße, unbehandelte Folie = 100) lieferte.In the actual cleaning cycle, which was carried out with a mechanically operated sponge, the amount of cleaning agent was 6 ml per strip. The evaluation of 7 strips, each treated in the same way, was carried out with a Lange color difference measuring device Microcolor, which gave the results in percent cleaning effect (based on the white, untreated film = 100).

Die Ergebnisse, die mit den einzelnen Mitteln in den vorgenannten Prüfverfahren erzeilt wurden, sind in Tabelle 2 zusammengefaßt worden. Bei den dort aufgeführten Mitteln 1a und 2a handelte es sich um Konzentrate, die Tenside und Wachs in den selben Verhältnissen wie die Mittel 1 bzw. 2, aber in 10fach höherer Konzentration enthielten. Tabelle 2 Prüfverfahren Beispiele 1 2 1a 2a 3 4 5 6 1. Rückstand auf schwarzen Kacheln    a) Konzentriert (erfindungsgemäß) 1 1 2 2 2-3 2-3    b) Verdünnung 10 g/l 3 3 2.
