Abstract

A composition consisting essentially of surfactants, non-metal-crosslinked polymers, alkaline-reacting complexing agents, and a water-soluble organic solvent is suitable for preserving and cleaning hard surfaces, particularly floors. It is used in highly dilute form and leaves behind a hard, but readily redissolvable transparent protective film.

Description

Auf dem Gebiet der Reinigung und Pflege von harten Oberflächen sind neben hygienischen und ästhetischen Aspekten vor allem wirtschaftliche Überlegungen und die Materialbeschaffenheit maßgebend für die Auswahl der Reinigungsverfahren und der einzusetzenden Mittel. Da jedem dieser Kriterien im Einzelfall unterschiedliche Bedeutung zukommt, ist es nicht erstaunlich, daß für diese Aufgaben bereits eine Vielzahl unterschiedlichster Verfahren und Mittel entwickelt worden sind.In the field of cleaning and maintenance of hard surfaces, in addition to hygienic and aesthetic aspects, economic considerations and the material properties are decisive for the selection of cleaning methods and the agents to be used. Since each of these criteria has different meanings in individual cases, it is not surprising that a multitude of different methods and means have already been developed for these tasks.

Die vorliegende Erfindung betrifft die Reinigung und Pflege von harten Oberflächen, insbesondere Fußböden, im Haushalt und in der gewerblichen Reinigung mit Hilfe wäßriger Reinigungsmittel. Auch auf diesem Gebiet sind bereits zahlreiche Verfahren und Mittel für die verschiedenen Anwendungszwecke entwickelt worden. Dabei wird die Auswahl der Mittel wesentlich dadurch bestimmt, ob vordringlich eine Reinigung oder eine Konservierung der Oberfläche erreicht werden soll.The present invention relates to the cleaning and care of hard surfaces, in particular floors, in the household and in commercial cleaning with the aid of aqueous cleaning agents. In this area too, numerous methods and agents have already been developed for the various purposes. The choice of agents is essentially determined by whether cleaning or preservation of the surface should be achieved as a matter of priority.

So verwendet man zur Pflege und Konservierung von Oberflächen in erster Linie solche Mittel, die mehr oder weniger harte, widerstandsfähige Filme 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 lang anhaltende 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.For the care and preservation of surfaces, primarily those agents are used that produce more or less hard, resistant films. For this purpose, the agents usually contain, in emulsified form, waxes or film-forming polymers and crosslinking agents, as a rule heavy metal salts which, after drying, form self-glossy or polishable films on the treated surfaces. In this way, long-lasting preservation of the surfaces can be achieved, and, depending on the quality of the film, strong mechanical loads can also be tolerated well. 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 enthalten Mittel, deren Wirkungsschwerpunkt bei der Reinigung liegt, hohe Anteile an Tensiden, oft zusammen mit alkalisch reagierenden Stoffen, organischen Lösungsmitteln oder Abrasivstoffen. 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, agents that focus on cleaning contain high levels 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 followed.

Da in vielen Fällen Reinigung und Pflege von Oberflächen gleichermaßen erwünscht sind, hat es nicht an Versuchen gefehlt, aus Gründen der Arbeitsvereinfachung Mittel zu entwickeln, mit denen Reinigung und Konservierung in einem Arbeitsgang erreicht werden können. Die bisherigen Lösungsvorschläge befriedigen jedoch nicht.Since in many cases cleaning and care of surfaces are equally desirable, there has been no shortage of attempts to develop means to simplify work and to achieve cleaning and preservation in one operation. However, the previous proposed solutions are unsatisfactory.

So führen beispielsweise Mittel, die die üblichen Filmbildner in sehr niedriger Konzentration zusammen mit Tensiden enthalten, häufig zu einer störenden Filmaddition, die nach gewissen Zeiten eine Zusatzreinigung erforderlich macht. Andere Mittel erfordern spezielle, teure Polymere oder bilden zu weiche Filme, die nur geringen Schutz gegen Wiederanschmutzung bieten. Auch Mittel auf Seifenbasis, die ebenfalls in diese Kategorie gehören, liefern recht weiche Filme und sind zudem anfällig gegen Wasserhärte.For example, agents that contain the usual film formers in very low concentrations together with surfactants often lead to a disruptive film addition, which requires additional cleaning after certain times. Other agents require special, expensive polymers or form films that are too soft and offer little protection against re-soiling. Soap-based agents, which also belong to this category, also produce very soft films and are also prone to water hardness.

Wieder andere Mittel dienen vor allem dazu, hohen Glanz auf den Oberflächen zu erzeugen. So werden in FR-A 2 294 231 Mittel vorgeschlagen, die 5-20 Gew.-% verschiedener carboxylgruppenhaltiger Polymerer neben bestimmten Mischungen aus anionischen und nichtionischen Tensiden enthalten. In den Mitteln der US-A 4 230 605 werden bestimmte Copolymere in Gegenwart einer Tensidkombination von Fettsäurediethanolamiden und Alkylbenzolsulfonsäure-diethanolaminsalzen eingesetzt. Die NL-A 6 900 307 schließlich beschreibt Mittel, die bestimmte Polymere, Weichmacher und bestimmte Phosphonsäuren enthalten.Still other means serve above all to create a high gloss on the surfaces. For example, FR-A 2 294 231 proposes compositions which contain 5-20% by weight of different carboxyl-containing polymers in addition to certain mixtures of anionic and nonionic surfactants. In the agents of US Pat. No. 4,230,605, certain copolymers are used in the presence of a surfactant combination of fatty acid diethanolamides and alkylbenzenesulfonic acid-diethanolamine salts. Finally, NL-A 6 900 307 describes agents which contain certain polymers, plasticizers and certain phosphonic acids.

Es bestand daher nach wie vor die Aufgabe, zur gleichzeitigen Reinigung und Konservierung von harten Oberflächen, insbesondere Fußböden, Mittel mit verbesserter Wirkung zu entwickeln.It was therefore still the task to develop agents with improved effectiveness for the simultaneous cleaning and preservation of hard surfaces, in particular floors.

Die vorliegende Erfindung bietet eine Lösung dieser Aufgabe in Form eines Mittels, bestehend aus: 0,5 - 10 Gew.-% Tensid aus der Gruppe Additionsverbindungen von Ethylenoxid mit Alkoholen oder Alkylphenolen, Alkylbenzolsulfonate, Alkylsulfate, Alkansulfonate, Fettsäureestersulfonate und deren Mischungen,

  • 0,1 - 4,5 Gew.-% alkalilösliche, nicht metallvemetzte Polymerverbindung mit einer minimalen Filmbildetemperatur zwischen 0 und 70 °C,
  • 0,01 - 5 Gew.-% alkalisch reagierende Komplexbildner,
  • 0 - 3 Gew.-% Alkalisierungsmittel,
  • 0 - 40 Gew.-% wassermischbares organisches Lösungsmittel,
  • 0-5 Gew.-% Zusatzstoffe sowie
The present invention provides a solution to this problem in the form of an agent consisting of: 0.5-10% by weight of surfactant from the group consisting of addition compounds of ethylene oxide with alcohols or alkylphenols, alkylbenzenesulfonates, alkylsulfates, alkanesulfonates, fatty acid ester sulfonates and mixtures thereof,
  • 0.1 - 4.5% by weight of alkali-soluble, non-metal-crosslinked polymer compound with a minimum film-forming temperature between 0 and 70 ° C,
  • 0.01 - 5% by weight of alkaline complexing agents,
  • 0-3% by weight of alkalizing agent,

Die Anwendung dieses Mittels erfolgt in der Weise, daß zunächst durch Verdünnen mit Wasser eine vorzugsweise ein- bis dreiprozentige Lösung des Mittels hergestellt wird, die dann mit Hilfe von Wischtüchem, Schwämmen oder ähnlichen Hilfsmitteln auf die zu reinigenden Oberflächen aufgetragen und zum Teil mit dem Schmutz wieder von der Oberfläche abgenommen wird. Nach dieser Behandlung wird die Oberfläche nicht abgespült, so daß die verbleibende Reinigungsmittellösung zu einem gleichmäßig schützenden Film auftrocknen kann. Wegen dieses Anwendungsverfahrens werden derartige Mittel auch als Wischpflegemittel bezeichnet. Das erfindungsgemäße Mittel zeichnet sich dabei trotz seiner einfachen Zusammensetzung durch eine optimale Reinigungswirkung gegenüber einer Vielzahl von Anschmutzungen aus und bildet gleichzeitig einen widerstandsfähigen Film, der einen hervorragenden Schutz gegen Wiederanschmutzung bildet. Im Gegensatz zu anderen Mitteln ist dieser Film hier vollständig transparent und läßt Farbe und Struktur der behandelten Flächen unverändert erscheinen, ohne daß ein zusätzlicher Glanz auftritt. Bei erneuter Anwendung des Mittels löst sich der Film auf und erleichtert dadurch den Reinigungsvorgang. Eine störende Filmaddition findet nicht statt.This agent is used in such a way that a preferably one to three percent solution of the agent is first prepared by dilution with water, which solution is then applied to the surfaces to be cleaned with the aid of wipers, sponges or similar aids and partly with the dirt is removed from the surface again. After this treatment, the surface is not rinsed off, so that the remaining cleaning agent solution can dry out to form an evenly protective film. Because of this application method, such agents are also referred to as wiping agents. Despite its simple composition, the agent according to the invention is distinguished by an optimal cleaning action against a large number of soiling and at the same time forms a resistant film which forms excellent protection against re-soiling. In contrast to other means, this film is completely transparent here Rent and lets the color and structure of the treated surfaces appear unchanged without any additional gloss. When the agent is used again, the film dissolves, making the cleaning process easier. There is no annoying film addition.

Das erfindungsgemäße Mittel eignet sich vorzugsweise zur pflegenden Reinigung von Fußböden und liefert dabei sowohl auf Stein, versiegeltem Parkett, Kacheln, Linoleum und Kunststoffböden ausgezeichnete Ergebnisse. Besonders vorteilhaft ist die Anwendung auf hochglänzenden Fußbodenbelägen, da der gebildete Film durch seine hohe Transparenz den Glanz nicht mindert. Vorzugsweise wird ein Mittel der folgenden Zusammensetzung verwendet:

  • 1 - 6 Gew.-% Tensid aus der Gruppe Additionsverbindungen von Ethylenoxid mit Alkoholen oder Alkylphenolen, Alkylbenzolsulfonate, Alkylsulfate, Alkansulfonate, Fettsäureestersulfonate und deren Mischungen,
  • 0,2 - 2,9 Gew.-% alkalilösliche, nicht metallvernetzte Polymerverbindung mit einer minimalen Filmbildetemperatur zwischen 0 und 70 °C,
  • 0,05 - 3 Gew.-% alkalisch reagierende Komplexbildner,
  • 0,05 - 2 Gew.-%Alkalisierungsmittel,
  • 0 - 20 Gew.-% wassermischbares organisches Lösungsmittel,
  • 0,05 - 2 Gew.-% Zusatzstoffe sowie
  • Rest Wasser.
The agent according to the invention is preferably suitable for the caring cleaning of floors and delivers excellent results on stone, sealed parquet, tiles, linoleum and plastic floors. Use on high-gloss floor coverings is particularly advantageous because the film formed does not reduce the gloss due to its high transparency. An agent of the following composition is preferably used:
  • 1-6% by weight of surfactant from the group of addition compounds of ethylene oxide with alcohols or alkylphenols, alkylbenzenesulfonates, alkylsulfates, alkanesulfonates, fatty acid ester sulfonates and mixtures thereof,
  • 0.2-2.9% by weight of alkali-soluble, non-metal-crosslinked polymer compound with a minimum film-forming temperature between 0 and 70 ° C,
  • 0.05 - 3% by weight of alkaline complexing agents,
  • 0.05-2% by weight of alkalizing agent,
  • 0-20% by weight of water-miscible organic solvent,
  • 0.05 - 2 wt .-% additives and
  • Rest of water.

Alkalilösliche PolymereAlkali-soluble polymers

Generell eignen sich alle in Wasser im alkalischen Bereich löslichen Polymerverbindungen, soweit sie nicht metallvernetzt sind und eine minimale Filmbildungstemperatur zwischen 0 und 70 °C aufweisen. Es handelt sich dabei in der Regel um Copolymerisate aus wenigstens drei verschiedenen Monomeren. Die Löslichkeit beträgt wenigstens 0,1 %, vorzugsweise 0,2 %, bei einem pH-Wert zwischen 8 und 10,5, insbesondere zwischen 8,5 und 9,5.In general, all polymer compounds soluble in water in the alkaline range are suitable, provided they are not metal-crosslinked and have a minimum film-forming temperature between 0 and 70 ° C. These are generally copolymers of at least three different monomers. The solubility is at least 0.1%, preferably 0.2%, at a pH between 8 and 10.5, in particular between 8.5 and 9.5.

Die vorzugsweise eingesetzten Polymeren enthalten als wichtigsten Bestandteil ein Acrylat-Copolymer aus 1 bis 30 Gewichtsteilen, bezogen auf Copolymer an carbonsäuregruppenhaltigen Monomeren, 30 bis 70 Gewichtsteilen Monomeren, die Homopolymere mit Glastemperaturen unter 20 °C bilden, vorzugsweise Estern der Acrylsäure mit C1 -C8 Alkoholen und/oder der Methacrylsäure mit C4 bis Cs-AI- koholen und 30 bis 70 Gewichtsteile Comonomeren, die Homopolymere mit Glastemperaturen über Raumtemperatur bilden, vorzugsweise Methacrylsäureester von Ct"bis C3-Alkoholen oder Styrol.As the most important constituent, the polymers preferably used contain an acrylate copolymer of 1 to 30 parts by weight, based on the copolymer of monomers containing carboxylic acid groups, 30 to 70 parts by weight of monomers which form homopolymers with glass transition temperatures below 20 ° C., preferably esters of acrylic acid with C 1 -C 8 alcohols and / or methacrylic acid with C 4 to C s alcohols and 30 to 70 parts by weight of comonomers which form homopolymers with glass transition temperatures above room temperature, preferably methacrylic acid esters of C 1 to C 3 alcohols or styrene.

Als säuregruppenhaltige Comonomere können ethylenisch ungesättigte Carbonsäuren eingesetzt werden; in erster Linie kommen Acrylsäure und Methacrylsäure in Frage.As comonomers containing acid groups, ethylenically unsaturated carboxylic acids can be used; acrylic acid and methacrylic acid are primarily suitable.

An Comonomeren mit Glastemperaturen unter 20 °C, also Glastemperaturen unter Raumtemperatur (bezogen jeweils auf Homopolymere eines Monomeren) sind Ester der Acrylsäure mit G-Ca-Alkoholen und Ester der Methacrylsäure mit C4-Ca-Alkoholen zu nennen. So können hier der Methyl-, Ethyl-, Propyl-, Butyl- oder 2-Ethylhexylester der Acrylsäure wie auch der Butyl-, Hexyl-oder 2-Ethylhexylester der Methacrylsäure eingesetzt werden. Comonomere, deren Homopolymere Glastemperaturen über Raumtemperatur aufweisen, sind Ester der Methacrylsäure mit Ci-C3-Alkoholen, wie beispielsweise Methylmethacrylat oder Ethylmethacrylat. Ein besonders wichtiges Comonomer, dessen Homopolymer eine Glastemperatur über Raumtemperatur aufweist, ist Styrol.Comonomers with glass transition temperatures below 20 ° C., that is glass transition temperatures below room temperature (based in each case on homopolymers of a monomer), include esters of acrylic acid with G-Ca alcohols and esters of methacrylic acid with C 4 -Ca alcohols. Thus, the methyl, ethyl, propyl, butyl or 2-ethylhexyl ester of acrylic acid can be used here, as can the butyl, hexyl or 2-ethylhexyl ester of methacrylic acid. Comonomers whose homopolymers have glass transition temperatures above room temperature are esters of methacrylic acid with C i -C 3 alcohols, such as methyl methacrylate or ethyl methacrylate. A particularly important comonomer whose homopolymer has a glass transition temperature above room temperature is styrene.

Vorzugsweise werden Copolymerisate von Acrylsäure und/oder Methacrylsäure mit Styrol, Acrylsäureestem und/oder Methacrylsäureestern eingesetzt. Besonders bevorzugt werden die Copolymerisate aus Acrylsäure oder Methacrylsäure mit unterschiedlichen Acryl- und/oder Methacrylsäureestem und/oder Styrol, beispielsweise Copolymerisate aus Acrylsäuremethylester, Acrylsäureethylester, Methacrylsäure und Styrol.Copolymers of acrylic acid and / or methacrylic acid with styrene, acrylic acid esters and / or methacrylic acid esters are preferably used. The copolymers of acrylic acid or methacrylic acid with different acrylic and / or methacrylic acid esters and / or styrene are particularly preferred, for example copolymers of methyl acrylate, ethyl acrylate, methacrylic acid and styrene.

Die jeweiligen Verhältnisse von Comonomeren, deren Homopolymere Glastemperaturen unter Raumtemperatur aufweisen und Monomeren, deren Homopolymere Glastemperaturen über Raumtemperatur aufweisen, sind so einzustellen, daß die Filmbildungstemperatur der Polymerdispersion im Bereich zwischen 0 und 70 °C liegt. Dabei gilt das allgemeine Wissen der Polymerchemie. Die genannten Filmbildungstemperaturen beziehen sich auf das weichmacherfreie System, d. h. auf die Polymeren ohne weitere Zusätze.The respective ratios of comonomers whose homopolymers have glass transition temperatures below room temperature and monomers whose homopolymers have glass transition temperatures above room temperature must be set so that the film-forming temperature of the polymer dispersion is in the range between 0 and 70 ° C. The general knowledge of polymer chemistry applies. The film formation temperatures mentioned relate to the plasticizer-free system, i. H. on the polymers without further additives.

Die Polymeren sind vorzugsweise nur im alkalischen Bereich in Wasser löslich, während sie im sauren Bereich ungelöst bleiben. Entsprechende Produkte werden vom Handel vielfach in emulgierter Form angeboten.The polymers are preferably soluble in water only in the alkaline range, while they remain undissolved in the acidic range. Corresponding products are often offered by the trade in emulsified form.

In den erfindungsgemäßen Mitteln werden 0,1 bis 4,5 Gew.-% der Polymeren, gerechnet als reines Polymeres, verwendet. Bevorzugte Gehalte sind 0,2 bis 2,9 Gew.-%, insbesondere 0,2 bis 1,0 Gew.-%.0.1 to 4.5% by weight of the polymers, calculated as pure polymer, are used in the agents according to the invention. Preferred contents are 0.2 to 2.9% by weight, in particular 0.2 to 1.0% by weight.

Geeignet sind insbesondere Pentanatriumtriphosphat, Trinatriumcitrat, Natriumgluconat,Tetranatriumethylendiamintetraacetat (EDTA-Na) und Trinatriumnitrilotriacetat (NTA-Na). Vorzugsweise werden EDTA-Na und/oder Natriumgluconat verwendet. Die Mengen betragen 0,01 bis 5 Gew.-%, vorzugsweise 0,05 bis 3 Gew.-% und insbesondere nicht mehr als 1 Gew.-%, bezogen auf das gesamte Mittel.Suitable for the agents according to the invention are water-soluble, preferably low molecular weight complexing agents (builders) which are able to prevent disturbances due to the water hardness when the agents are used. Pentasodium triphosphate, trisodium citrate, sodium gluconate, tetrasodium ethylenediaminetetraacetate (EDTA-Na) and trisodium nitrilotriacetate (NTA-Na) are particularly suitable. EDTA-Na and / or sodium gluconate are preferably used. The amounts are 0.01 to 5% by weight, preferably 0.05 to 3% by weight and in particular not more than 1% by weight, based on the total composition.

AlkalisierungsmittelAlkalizing agent

Die Alkalisierungsmittel dienen zusammen mit den Komplexbildnem dazu, den Mitteln im unverdünnten Zustand einen pH-Wert von 8 bis 10,5, vorzugsweise 8,5 bis 9,5 zu geben. Bei diesen pH-Werten liegen die Polymeren wenigstens partiell in der Salzform vor. Die Wahl dieser Mittel ist unkritisch, soweit sie mit den übrigen Bestandteilen verträglich sind. Geeignet sind beispielsweise Ammoniak, Alkanolamine, alkalisch reagierende Salze wie Na2C03 oder NaOH. Vorzugsweise wird Ammoniak verwendet. Die Alkalisierungsmittel werden in Mengen bis zu 3 Gew.-%, vorzugsweise 0,05 bis 2 Gew.-% eingesetzt.The alkalizing agents together with the complexing agents serve to give the agents in the undiluted state a pH of 8 to 10.5, preferably 8.5 to 9.5. At these pH values, the polymers are at least partially in the salt form. The choice of these agents is not critical insofar as they are compatible with the other ingredients. For example, ammonia, alkanolamines, alkaline salts such as Na 2 CO 3 or NaOH are suitable. Ammonia is preferably used. The alkalizing agents are used in amounts of up to 3% by weight, preferably 0.05 to 2% by weight.

Wassermischbare oraanische LösungsmittelWater-miscible organic solvents

Zur Verstärkung der Reinigungskraft können wassermischbare organische Lösungsmittel enthalten sein, wobei gut fettlösende Lösungsmittel bevorzugt werden. Beispiele für derartige Lösungsmittel sind niedere Mono- und Dialkohole, Etheralkohole, Polyether und Amine. Typische Vertreter dieser Lösungsmittelgruppen sind etwa Isopropanol, Butylglykol, Dimethyldiglykol und Methylpyrrolidon. Vorzugsweise werden niedere Etheralkohole , beispielsweise Mono- oder Diethylenglykolmonoalkylether mit 1 bis 4 C-Atomen in der Alkylgruppe verwendet. Der Gehalt an Lösungsmitteln liegt nicht über 40 Gew.- %, vorzugsweise nicht über 20 Gew.-% und insbesondere zwischen 0,5 und 10 Gew.-%.To increase the cleaning power, water-miscible organic solvents can be present, with solvents that are highly fat-dissolving preferred. Examples of such solvents are lower mono- and dialcohols, ether alcohols, polyethers and amines. Typical representatives of these solvent groups are isopropanol, butyl glycol, dimethyl diglycol and methyl pyrrolidone. Lower ether alcohols, for example mono- or diethylene glycol monoalkyl ethers having 1 to 4 carbon atoms in the alkyl group, are preferably used. The solvent content is not more than 40% by weight, preferably not more than 20% by weight and in particular between 0.5 and 10% by weight.

ZusatzstoffeAdditives

Durch die Einarbeitung dieser üblichen Stoffe können zusätzlich Effekte, wie sie insbesondere bei der Fußbodenreinigung erwünscht sind, beispielsweise ein angenehmer Geruch oder eine desinfizierende Wirkung, erreicht werden. Weiterhin können sie dazu dienen, die Mittel selbst zu stabilisieren und ansprechend zu gestalten.The incorporation of these customary substances can additionally achieve effects such as are particularly desired in floor cleaning, for example a pleasant smell or a disinfectant effect. They can also serve to stabilize the funds themselves and make them attractive.

Beispiele derartiger Zusatzstoffe sind anorganische Neutralsalze, Farbstoffe, Duftstoffe, Schauminhibitoren und antimikrobielle Wirkstoffe. Es ist selbstverständlich, daß bei der Auswahl nur solche Vertreter dieser Stoffe gewählt werden, die mit den übrigen Bestandteilen der Mittel verträglich sind und die Wirkung der Mittel nicht beeinträchtigen. Die Mengen an Zusatzstoffen betragen insgesamt nicht mehr als 5 Gew.-%, vorzugsweise nicht mehr als 2 Gew.-% und insbesondere zwischen 0,05 und 0,5 Gew.-% der Mittel.Examples of such additives are inorganic neutral salts, dyes, fragrances, foam inhibitors and antimicrobial agents. It goes without saying that only representatives of these substances who are compatible with the other constituents of the agents are selected and do not affect the effectiveness of the funds. The total amount of additives is not more than 5% by weight, preferably not more than 2% by weight and in particular between 0.05 and 0.5% by weight of the composition.

Prüfung der ReinigungswirkungTesting the cleaning effect

Die Reinigungswirkung der Wischpflegemittel wurde mit Hilfe eines Gardner-Waschbarkeits- und Scheuerprüfgerätes ermittelt, wie es in den Qualitätsnormen des Industrieverbandes Putz- und Pflegemittel e. V. beschrieben ist (Seifen-Öle-Fette-Wachse, 108, Seiten 526 - 528 (1982)). Bei dieser Methode wird eine weiße PVC-Folie mit einer Testanschmutzung aus Ruß und Fett versehen und unter standardisierten Bedingungen mit einem mit dem Reinigungsmittel getränkten Schwamm maschinell gewischt. Die Reinigungsleistung wird durch photoelektrische Bestimmung des Remissionsgrades gemessen.The cleaning effect of the wiping care products was determined with the help of a Gardner washability and abrasion tester, as described in the quality standards of the industrial association cleaning and care products e. V. (Seifen-Öle-Fette-Wwachs, 108, pages 526-528 (1982)). In this method, a white PVC film is soiled with soot and grease and, under standardized conditions, is wiped mechanically with a sponge soaked in the cleaning agent. The cleaning performance is measured by photoelectric determination of the reflectance.

Prüfuna der PfleaewirkunaPrüfuna der Pfleaewirkuna

Die Pflegewirkung zeigt sich unter anderem darin, daß durch einen aus früheren Behandlungen mit demselben Mittel stammenden Film die Ablösung von nachträglich aufgebrachten Anschmutzungen erleichtert wird.The care effect is shown, among other things, by the fact that a film from previous treatments with the same agent facilitates the detachment of subsequently applied soiling.

Das oben angegebene Prüfverfahren wurde deshalb in der Weise modifiziert, daß die Folie vor dem Aufbringen der gleichen Anschmutzung mit dem zu prüfenden Wischpflegemittel gewischt und dann getrocknet wurde. Nach dem Aufbringen der Anschmutzung erfolgte die Prüfung dann wie die Prüfung der Reinigungsleistung:

  • Tabelle 3 führt die Ergebnisse der Prüfungen an allen acht Mitteln auf. Sie sind in Prozent Lichtremission bezogen auf weiß = 100 % angegeben. In allen Prüfungen wurden die Mittel in verdünnter Form mit einer Konzentration von 2 Gewichtsprozent angewendet.
The test method specified above was therefore modified in such a way that the film was wiped with the wiping agent to be tested and then dried before the same stain was applied. After applying the soiling, the test was then carried out like the cleaning performance:
  • Table 3 lists the results of the tests on all eight agents. They are given in percent light emission based on white = 100%. In all tests, the agents were used in a diluted form with a concentration of 2 percent by weight.

Aus den Ergebnissen wird deutlich, daß die erfindungsgemäßen Wischpflegemittel 1 - 5 eine ausgezeichnete Reinigungsleistung sowohl gegenüber nicht vorbehandelter als auch gegenüber vorbehandelter Folie aufweisen. Von vorbehandelter Folie wird dabei die Anschmutzung noch besser entfernt als von der ursprünglichen Folie.It is clear from the results that the wiping agents 1-5 according to the invention have an excellent cleaning performance both with respect to non-pretreated and to pretreated film. Soiling from pretreated film is removed even better than from the original film.

Die zum Vergleich herangezogenen Mittel 6 - 8 zeigen dagegen gute Reinigungsleistungen entweder nur an unvorbehandelter Folie (6) oder nur an vorbehandelter Folie (7, 8). Das Mittel 8 ist dabei in seiner Pflegewirkung durchaus mit den erfindungsgemäßen Mitteln vergleichbar, führt aber anders als diese, nach mehrfacher Anwendung zu einer Filmaddition, die das natürliche Aussehen der behandelten Flächen beeinträchtigt.

Figure imgb0004
The means 6 - 8 used for comparison, on the other hand, show good cleaning performance either only on untreated film (6) or only on pretreated film (7, 8). The care effect of the agent 8 is quite comparable to that of the agents according to the invention, but unlike these, after multiple use leads to a film addition which adversely affects the natural appearance of the treated surfaces.
