Description

Die voritegehde Erfindung betrifft wässrige, gerüststoff- und lösungsmittelfreie Reinigungsmittel für Glas, insbesondere Fenster, Spiegel und ähnliche reflektierende Oberflächen, nachfolgend «Fensterreinigungsmittei" genannt.The voritegehde invention relates to aqueous, builders and solvent-free cleaning agents for glass, in particular windows, mirrors and similar reflective surfaces, hereinafter referred to as "window cleaning agents".

Fensterreinigungsmittel kommen beim Gebrauch im Haushalt meist mit der Haut der Hände der Benutzer in Berührung und müssen daher entsprechend milde sein, d.h. sie sollen in erster Linie die Haut, aber auch umliegende Flächen aus Lack, Holz, Leder und dergleichen möglichst wenig angreifen und schädigen. Darüber hinaus müssen sie wirksam genug sein, den üblichen fett-und pigmenthaltigen Schmutz von Fensterscheiben, Spiegeln, Glassteinen, Autoscheiben und ähnlichen reflektierenden Oberflächen zu entfernen. Schllessllch sollen die gereinigten Oberflächen schnell und streifenfrei, ohne mechanisches Nachpolieren, auftrocknen.When used in the home, window cleaning agents mostly come into contact with the skin of the users' hands and must therefore be correspondingly mild, i.e. They are primarily intended to attack and damage the skin as little as possible, but also surrounding surfaces made of lacquer, wood, leather and the like. In addition, they must be effective enough to remove the usual greasy and pigmented dirt from window panes, mirrors, glass stones, car windows and similar reflective surfaces. Finally, the cleaned surfaces should dry quickly and without streaks, without mechanical polishing.

Derartige Mittel enthalten im allgemeinen Ammoniak und/oder eine organische oberflächenaktive Verbindung mit hoher Netzfähigkeit in wässriger Lösung, der noch wasserlösliche organische Lösungsmittel wie beispielsweise niedermolekulare aliphatische Alkohole, Glycole, Glycolether oder Aceton zugesetzt werden können.Such agents generally contain ammonia and / or an organic surface-active compound with high wettability in aqueous solution, to which water-soluble organic solvents such as, for example, low molecular weight aliphatic alcohols, glycols, glycol ethers or acetone can be added.

Aus der DE-A-2 616 404 sind entsprechende Reinigungsmittel bekannt, die es ermöglichen sollen, dass Glasflächen beim Reinigungs- und Spülvorgang ohne gesondertes Abtrocknen fleckenfrei erhalten werden können. Dies sind wässrige Medien, die 0,01-1 Gew.-% eines wasserlöslichen Tensids und ein wasserlösliches, nichtproteinisches, kationisches Polymer mit einem Molekulargewicht von 25 000 bis 10 000 000 enthalten, wobei das Gewichtsverhältnis des Tensids zum Polymer in der Spülflüssigkeit etwa 2: 1 bis etwa 1000: 1 betragen soll. Bei diesen Mitteln wird jedoch ein Abspülen der Glasflächen vor dem Trockenlassen empfohlen, was beim Reinigen grosser Glasflächen im Haushalt, d.h. In geschlossenen Räumen nicht immer möglich, in jedem Falle aber unbequem ist. Ein weiterer Nachteil dieser kationischen Polymeren ist ihre Unverträglichkeit mit anionischen Verbindungen, so dass z. B. die gebräuchliche Mitverwendung von Aniontensiden stark eingeschränkt ist.Corresponding cleaning agents are known from DE-A-2 616 404 which are intended to make it possible for glass surfaces to be kept free of stains during the cleaning and rinsing process without separate drying. These are aqueous media containing 0.01-1% by weight of a water-soluble surfactant and a water-soluble, non-proteinic, cationic polymer with a molecular weight of 25,000 to 10,000,000, the weight ratio of the surfactant to the polymer in the rinsing liquid being about 2 : 1 to about 1000: 1. With these products, however, it is recommended that the glass surfaces be rinsed before they are left to dry, which is important when cleaning large glass surfaces in the home, i.e. Not always possible in closed rooms, but is uncomfortable in any case. Another disadvantage of these cationic polymers is their incompatibility with anionic compounds, so that, for. B. the common use of anionic surfactants is greatly restricted.

Man hat daher entsprechend der Lehre der DE-A-2 220 540 wässrigen oder wässrig-alkoholischen Fensterreinigungsmitteln mit einem Gehalt an 0,01-5 Gew.-% eines nichtionischen oder anionischen oberflächenaktiven Mittels und gegebenenfalls auch Ammoniak etwa 0,03-2 Gew.-% eines löslichen polymeren Salzes zugesetzt, wobei das polymere Salz aus einem Copolymeren von 1-2 Mol eines monovinylaromatischen Monomeren pro Mol einer ungesättigten Dicarbonsäure bzw. deren Anhydrid besteht, welches mit einer ausreichenden Menge Ammoniak, einer Alkalimetall-Base oder einem Amin unter Bildung von löslichmachenden Salzgruppierungen neutralisiert ist. Durch diesen Zusatz sollen die Streifenbildung auf den gereinigten Glasflächen sowie deren Beschlagen bei hoher Luftfeuchtigkeit vermindert und ihnen eine staubabweisende Ausrüstung verliehen werden. Mit diesen Mitteln, die einerseits die dort beanspruchten polymeren Salze in den niedrigen Mengen des beanspruchten Konzentratrionsbereichs enthalten, erzielt man zwar auf nur sehr wenig angeschmutzten Fensterscheiben oder Spiegeln einen guten Antibeschlageffekt, sie besitzen aber eine nur geringe Reinigungswirkung. Auf natürlich angeschmutzten Fenstern, die auf der Innenseite etwa Zigarettenrauch oder Zentralheizungsluft und auf der Aussenseite des abluftstarken Strassenverkehrs ausgesetzt sind, reicht die Reinigungsleistung bei weitem nicht aus. Die Folge ist ein Verschmieren der von der Flotte nicht aufgenommenen Schmutzbestandteile auf der Scheibenfläche, so dass nach dem Reinigungsvorgang Schleier oder Schlieren zurückbleiben, also keine ausreichende Reinigung erfolgt. Erhöht man anderseits den Gehalt an polymeren Salzen innerhalb des beanspruchten Konzentrationsbereichs, so wird zwar die Schmutzentfernung besser, jedoch bilden sich dann auf den Glasflächen Rückstände aus der Reinigungsflotte. Diese Rückstände lassen sich durch trockenes Polieren nicht entfernen, und man ist dann ebenfalls gezwungen, mit klarem Wasser nachzuwischen.Therefore, according to the teaching of DE-A-2 220 540, aqueous or aqueous-alcoholic window cleaning agents with a content of 0.01-5% by weight of a nonionic or anionic surface-active agent and optionally also ammonia have about 0.03-2% by weight .-% added a soluble polymeric salt, wherein the polymeric salt consists of a copolymer of 1-2 moles of a monovinyl aromatic monomer per mole of an unsaturated dicarboxylic acid or its anhydride, which with a sufficient amount of ammonia, an alkali metal base or an amine Formation of solubilizing salt groups is neutralized. This addition is intended to reduce the formation of stripes on the cleaned glass surfaces and their fogging in the presence of high atmospheric humidity, and to provide them with a dust-repellent finish. With these agents, which on the one hand contain the polymeric salts claimed there in the low amounts of the concentration range claimed, a good anti-fog effect is achieved on only very little soiled window panes or mirrors, but they have only a slight cleaning effect. The cleaning performance is far from sufficient on naturally soiled windows that are exposed to the inside, for example, of cigarette smoke or central heating air, and on the outside to heavy-duty traffic. The result is smearing of the dirt constituents not absorbed by the liquor on the pane surface, so that after the cleaning process, veils or streaks remain, ie insufficient cleaning is carried out. On the other hand, if the content of polymeric salts is increased within the concentration range claimed, the dirt removal will be better, but residues from the cleaning liquor will then form on the glass surfaces. These residues cannot be removed by dry polishing, and you are then also forced to wipe with clear water.

Auch nach der Lehre der US-A-3 939 090 werden Fensterreinigungsmitteln zur verbesserten Reinigungsleistung und Antibeschlagwirkung 0,01-0,1 Gew.-% eines Copolymeren aus einem von einem ethylenisch ungesättigten Carbonsäureanhydrid oder -teilester abgeleiteten Monomeren mit einem carboxylgruppenfreien ethylenisch ungesättigten Monomeren zugesetzt, das ein Molgewicht von etwa 400 bis etwa 2 000 000 haben kann. Damit diese Mittel ihre Wirkung voll entfalten können, ist ausserdem ein Zusatz von Lösungsmitteln unerlässlich.According to the teaching of US Pat. No. 3,939,090, window cleaning agents for improved cleaning performance and anti-fog effect are 0.01-0.1% by weight of a copolymer of a monomer derived from an ethylenically unsaturated carboxylic acid anhydride or partial ester with a carboxyl-free ethylenically unsaturated monomer added, which can have a molecular weight of about 400 to about 2,000,000. In order for these agents to be fully effective, the addition of solvents is also essential.

Es wurde nun gefunden, dass man die mit den bekannten Polymerenzusätzen verbundenen Nachteile vermeiden kann, wenn man einem gerüststoff- und lösungsmittelfreien Fensterreiniger auf Basis wässriger Tensidlösungen geringe Mengen nichtionischer Polymerer, nämlich Polyethylenglycole mit Molgewichten zwischen 300 000 und 4 000 000, vorzugsweise zwischen 500 000 und 1 000 000, zusetzt. Überraschend war vor allem die unerwartet hohe Reinigungsverstärkung durch die sehr geringen Zusatzmengen dieser Polymeren bei gleichzeitig guter Antibeschlagwirkung, die der bei Verwendung der bekannten ionischen Polymeren entspricht. Darüber hinaus haben die erfindungsgemäss eingesetzten Polyethylenglycole die Fähigkeit, den Reibungswiderstand beim Abwischen der Glasoberflächen zu verringern, so dass der Abwischvorgang erleichtert wird. Ferner zeichnen sie sich gegenüber den bekannten zugesetzten Polymeren dadurch aus, dass sie mit nahezu allen gebräuchlichen Tensiden verträglich sind und dass die mit ihnen versetzten Fensterreinigungsmittel weder Lösungsmittelzusätze benötigen noch die mit ihnen gereinigten Flächen eines Nachspülens mit klarem Wasser bedürfen.It has now been found that the disadvantages associated with the known polymer additives can be avoided if a window cleaner based on aqueous surfactant solutions which is free of builders and solvents is used to avoid small amounts of nonionic polymers, namely polyethylene glycols with molecular weights between 300,000 and 4,000,000, preferably between 500,000 and 1,000,000. What was particularly surprising was the unexpectedly high cleaning strengthening due to the very small amounts of these polymers added and at the same time a good anti-fogging effect, which corresponds to that when using the known ionic polymers. In addition, the polyethylene glycols used according to the invention have the ability to reduce the frictional resistance when wiping the glass surfaces, so that the wiping process is facilitated. They are also distinguished from the known added polymers from the fact that they are compatible with almost all common surfactants and that the window cleaning agents they contain do not require the addition of solvents, nor do the surfaces cleaned with them require rinsing with clear water.

Die vorliegende Erfindung betrifft daher wässrige Reinigungsmittel für Glas, insbesondere für Fenster, Spiegel und reflektierende Oberflächen mit einem Gehalt an Tensiden, wasserlöslichen Polymerverbindungen sowie gegebenenfalls basischen Verbindungen in entmineralisiertem Wasser, dadurch gekennzeichnet, dass sie als wasserlösliche Polymerverbindung 0,01-0,5, vorzugsweise 0,05-0,2 Gew.-% nichtionische Polymere aus der Gruppe der Polyethylenglykole mit Molgewichten zwischen 300 000 und 4 000 000, vorzugsweise zwischen 500 000 und 1 000 000, zusammen mit 0,1-5, vorzugsweise 0,5-5 Gew.-% anionischen, nichtionischen oder kationischen Tensiden oder geeigneten Gemischen daraus, wobei die anionischen Tenside vorzugsweise synthetischer Natur sind, und wobei 0-5, vorzugsweise 0,1-2 Gew.-% einer basischen Verbindung, insbesondere Ammoniak, vorhanden sein können, enthalten und im übrigen gerüststoff- und lösungsmittelfrei sind. Sie können zusätzlich noch sonstige übliche Hilfsstoffe, insbesondere Duft- und Farbstoffe und Konservierungsmittel enthalten.The present invention therefore relates to aqueous cleaning agents for glass, in particular for windows, mirrors and reflecting surfaces containing surfactants, water-soluble polymer compounds and, if appropriate, basic compounds in demineralized water, characterized in that they are used as water-soluble polymer compounds 0.01-0.5, preferably 0.05-0.2% by weight of nonionic polymers from the group of the polyethylene glycols with molecular weights between 300,000 and 4,000,000, preferably between 500,000 and 1,000,000, together with 0.1-5, preferably 0.5 -5% by weight of anionic, nonionic or cationic surfactants or suitable mixtures thereof, the anionic surfactants preferably being synthetic, and 0-5, preferably 0.1-2% by weight of a basic compound, in particular ammonia, being present can be included and are otherwise free of builders and solvents. They can also contain other customary auxiliaries, in particular fragrances and dyes and preservatives.

Die Fensterreiniger werden für den Gebrauch mit Wasser im Verhältnis 1 : 10 bis 1 : 100 zur sogenannten Gebrauchslösung verdünnt. Die Gebrauchslösung kann entweder mit Hilfe eines Schwammes oder Tuches auf die Glasflächen appliziert werden oder aber mittels einer Sprühpumpe direkt auf die Oberfläche gesprühf und sofort anschliessend mit einem Fensterleder, einem Gummischieber oder einem Tuch abgewischt werden. Ein Nachwischen oder Trockenpolieren ist nicht erforderlich.The window cleaners are diluted for use with water in a ratio of 1:10 to 1: 100 to the so-called working solution. The working solution can either be applied to the glass surfaces using a sponge or cloth or sprayed directly onto the surface using a spray pump and then immediately wiped off with a chamois, a rubber slide or a cloth. Wiping or dry polishing is not necessary.

Die genannten Polyethylenglycole werden in bekannter Weise dadurch hergestellt, dass man Ethylenglycole in bekannter Weise einem Polykondensationsprozess unterwirft. Man kann sie auch als Kondensationspolymere des Ethylenoxids mit Ethylenglycol oder Wasser auffassen. Sie besitzen die allgemeine Formel HO(-CH2-CH2-O)nH, wobei n im Falle der erfindungsgemäss eingesetzten Polyethylenglycole zwischen 4800 und 64 600 variieren kann.The polyethylene glycols mentioned are prepared in a known manner by subjecting ethylene glycols to a polycondensation process in a known manner.

Die einsetzbaren Tenside und Tensidgemische sind praktisch nicht beschränkt. Lediglich Seifen sollten wegen ihrer Neigung zur Kalkfleckenbildung in hartem Wasser nicht verwendet werden und die bekannte Unverträglichkeit der meisten Gemische aus anionischen und kationischen Tensiden ist zu beachten.The surfactants and surfactant mixtures that can be used are practically not restricted. Only soaps should not be used due to their tendency to form limescale in hard water and the well-known incompatibility of most mixtures of anionic and cationic surfactants should be noted.

Die Tenside enthalten im Molekül wenigstens einen hydrophoben organischen Rest und einen wasserlöslichmachenden anionischen, nichtionischen oder kationischen Rest. Bei dem hydrophoben Rest handelt es sich meist um einen aliphatischen Kohlenwasserstoffrest mit 8-26, vorzugsweise 10-22 und insbesondere 12-18 C-Atomen oder um einen alkylaromatischen Rest mit 6-18, vorzugsweise 8-16 aliphatischen C-Atomen.The surfactants contain at least one hydrophobic organic radical and one water-solubilizing anionic, nonionic or cationic radical in the molecule. The hydrophobic radical is usually an aliphatic hydrocarbon radical with 8-26, preferably 10-22 and in particular 12-18 C atoms or an alkyl aromatic radical with 6-18, preferably 8-16 aliphatic C atoms.

Als anionische Tenside sind z.B. solche vom Typ der Sulfonate, Sulfate und der synthetischen Carboxylate brauchbar.As anionic surfactants e.g. those of the sulfonate, sulfate and synthetic carboxylate type are useful.

Als Tenside vom Sulfonattyp kommen Alkylbenzolsulfonate (C9-,rAlkyl), Gemische aus Alken-und Hydroxyalkansulfonaten sowie Disulfonaten, wie man sie beispielsweise aus Monoolefinen mit end- oder innenständiger Doppelbindung durch Sulfonieren mit gasförmigem Schwefeltrioxid und anschliessende alkalische oder saure Hydrolyse der Sulfonierungsgruppe erhält, in Betracht. Weiter eignen sich Alkansulfonate, die aus Alkanen durch Sulfochlorierung oder Sulfoxydation und anschliessende Hydrolyse bzw. Neutralisation bzw. durch Bisulfitaddition an Olefine erhältlich sind. Weitere brauchbare Tenside vom Sulfonattyp sind die Ester von a-Sulfofettsäuren, z.B. die a-Sulfonsäuren aus hydrierten Methyl- oder Ethylestern der Cocos-, Palmkern- oder Talgfettsäure.Suitable surfactants of the sulfonate type are alkylbenzenesulfonates (C9-, alkyl), mixtures of alkene and hydroxyalkanesulfonates and disulfonates, such as are obtained, for example, from monoolefins with terminal or internal double bonds by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acid hydrolysis of the sulfonation group Consider. Also suitable are alkanesulfonates which can be obtained from alkanes by sulfochlorination or sulfoxidation and subsequent hydrolysis or neutralization or by bisulfite addition to olefins. Other useful sulfonate type surfactants are the esters of a-sulfo fatty acids, e.g. the a-sulfonic acids from hydrogenated methyl or ethyl esters of coconut, palm kernel or tallow fatty acid.

Geeignete Tenside vom Sulfattyp sind die Schwefelsäuremonoester primärer Alkohole (z. B. aus Cocosfettalkoholen, Talgfettalkoholen oder Oleylalkohol) und diejenigen sekundärer Alkohole. Weiterhin eignen sich sulfatierte Fettsäurealkanolamide, Fettsäuremonoglyceride oder Umsetzungsprodukte von 1-4 Mol Ethylenoxid mit primären oder sekundären Fettalkoholen oder Alkylphenolen.Suitable sulfate-type surfactants are the sulfuric acid monoesters of primary alcohols (for example from coconut fatty alcohols, tallow fatty alcohols or oleyl alcohol) and those of secondary alcohols. Sulfated fatty acid alkanolamides, fatty acid monoglycerides or reaction products of 1-4 moles of ethylene oxide with primary or secondary fatty alcohols or alkylphenols are also suitable.

Weitere geeignete anionische Tenside sind die Fettsäureester bzw. -amide von Hydroxy- oder Amino-carbonsäuren bzw. -sulfonsäuren, wie z. B. die Fettsäuresarcoside, -glycolate, -lactate, -tauride oder -isethionate.Other suitable anionic surfactants are the fatty acid esters or amides of hydroxy or amino carboxylic acids or sulfonic acids, such as. B. the fatty acid sarcosides, glycolates, lactates, taurides or isethionates.

Die anionischen Tenside können in Form ihrer Alkali-, Erdalkali- und Ammoniumsalze. sowie als lösliche Salze organischer Basen, wie Mono-, Di-oder Triethanolamin vorliegen. Die Natriumsalze werden meist aus Kostengründen bevorzugt.The anionic surfactants can be in the form of their alkali, alkaline earth and ammonium salts. as well as soluble salts of organic bases, such as mono-, di- or triethanolamine. The sodium salts are mostly preferred for cost reasons.

Als nichtionische Tenside sind Anlagerungsprodukte von 4-40, vorzugsweise 4-20 Mol Ethylenoxid an 1 Mol Fettalkohol, Alkandiol, Alkylphenol, Fettsäure, Fettamin, Fettsäureamid oder Alkansulfonamid verwendbar. Besonders wichtig sind die Anlagerungsprodukte von 5-16 Mol Ethylenoxid oder Ethylen- und Propylenoxid an Cocos- oder Talgfettalkohole, an Oleylalkohol oder an sekundäre Alkohole mit 8-18, vorzugsweise 12-18 C-Atomen, sowie an Mono- oder Dialkylphenole mit 6-14 C-Atomen in den Alkylresten. Neben diesen wasserlöslichen Nonionics sind aber auch nicht bzw. nicht vollständig wasserlösliche Polyglycolether mit 1-4 Ethylenglycoletherresten im Molekül von Interesse, insbesondere, wenn sie zusammen mit wasserlöslichen nichtionischen oder anionischen Tensiden eingesetzt werden.Addition products of 4-40, preferably 4-20, moles of ethylene oxide and 1 mole of fatty alcohol, alkanediol, alkylphenol, fatty acid, fatty amine, fatty acid amide or alkanesulfonamide can be used as nonionic surfactants. The addition products of 5-16 moles of ethylene oxide or ethylene and propylene oxide with coconut oil or tallow fatty alcohols, with oleyl alcohol or with secondary alcohols with 8-18, preferably 12-18 C atoms, and with mono- or dialkylphenols with 6- 14 carbon atoms in the alkyl radicals. In addition to these water-soluble nonionics, non-fully or not completely water-soluble polyglycol ethers with 1-4 ethylene glycol ether residues in the molecule are also of interest, in particular if they are used together with water-soluble nonionic or anionic surfactants.

Weiterhin sind als nichtionische Tenside die wasserlöslichen, 20-250 Ethylenglycolethergruppen und 10-100 Propylenglycolethergruppen enthaltenden Anlagerungsprodukte von Ethylenoxid an Polypropylenoxid, Alkylendiaminpoly-propylenglycol und Alkylpolypropylenglycole mit 1-10 C-Atomen in der Alkylkette brauchbar, in denen die Polypropylenglycolkette als hydrophober Rest fungiert.Furthermore, the non-ionic surfactants are the water-soluble addition products containing 20-250 ethylene glycol ether groups and 10-100 propylene glycol ether groups Ethylene oxide on polypropylene oxide, alkylenediamine-polypropylene glycol and alkylpolypropylene glycols with 1-10 C atoms in the alkyl chain are usable, in which the polypropylene glycol chain acts as a hydrophobic radical.

Auch nichtionische Tenside vom Typ der Aminoxide sind verwendbar. Typische Vertreter sind beispielsweise die Verbindungen N-Dodecyl-N,N-dimethylaminoxid, N-Tetradecyl-N,N-dihydroxy- ethylaminoxid, N-Hexadecyl-N,N-bis-(2,3-dihydroxypropyl)-aminoxid.Nonionic surfactants of the amine oxide type can also be used.

Die kationischen Tenside enthalten wenigstens einen hydrophoben und wenigstens einen basischen, gegebenenfalls als Salz vorliegenden wassertöstichmachenden Rest. Bei dem hydrophoben Rest handelt es sich um einen aliphatischen oder cycioaiihatischen Kohlenwasserstoffrest mit vorzugsweise 10-22 C-Atomen oder um einen alkyl- bzw. cycioaikylaromatischen Rest mit vorzugsweise 8-16 aliphatischen C-Atomen. Als basische Reste kommen in erster Linie basische Stickstoffatome in Frage, die auch mehrfach in einem Tensidmoiekül vorhanden sein können; bevorzugt handelt es sich um quartäre Ammoniumverbindungen wie beispielsweise N-Dodecyl-N,N,N-trimethylammoniummethosulfat, N-Hexadecyl- bzw. N-Octadecyl-N,N,N-trimethylam- moniumchiorid, N,N-Dicocosalkyl-N,N-dimethyl- ammoniumchlorid, N-Dodecyl-N,N-dimethyl-N-benzytammonlumbromid, das Umsetzungsprodukt von 1 Mol Talgalkylamin mit 10 Mol Ethylenoxid, N-Dodecyl-N,N',N'-trimethyl-1,3-diaminopropan, N-Hexadecylpyridiniumchlorid.The cationic surfactants contain at least one hydrophobic and at least one basic, optionally present as a salt water-repellent residue.

The additions of colors and fragrances are variable and depend on the availability, their resistance in slightly alkaline cleaning agents and on the current taste.

VersuchsmethodenTest methods

Die Antl-Nebelbildung wurde unter Laborbedingungen dadurch geprüft, dass man Spiegel von der Grösse 40 x 50 cm zunächst sorgfältig säuberte und trocknete, mit einem Fettstift eine Mittellinie markierte und dann die eine Hälfte mit dem erfindungsgemässen Fensterreinigungsmittel und die andere Hälfte mit einem Vergleichsprodukt behandelte. Nach dem Trocknen an der Luft wurden vor beide Spiegelhälften gleich grosse Gefässe mit siedendem Wasser gestellt und die Nebelbildung auf dem Spiegel beobachtet.The formation of Antl mist was checked under laboratory conditions by first carefully cleaning and drying mirrors measuring 40 x 50 cm, marking a center line with a grease pencil and then treating half with the window cleaning agent according to the invention and the other half with a comparative product. After drying in air, were placed in front of both mirrors älften h equal to large vessels with boiling water and observed the fog on the mirror.

Diese Labormethode wurde in die Praxis umgesetzt, indem man Badezimmerspiegel wie vorstehend behandelte und anschliessend die Dusche mit Heisswasser aufdrehte, so dass sich im Badezimmer Wasserdampf entwickelte. Dabei wurde das Beschlagen der Spiegelhälften beobachtet. Es ergab sich in allen Fällen völlige Übereinstimmung zwischen den Ergebnissen der Labormethode und dem praktischen Test.This laboratory method was put into practice by treating the bathroom mirror as above and then turning the shower on with hot water so that water vapor developed in the bathroom. Fogging of the mirror halves was observed. In all cases, there was complete agreement between the results of the laboratory method and the practical test.

Die Reinigungswirkung, die Leichtigkeit des Abwischvorgangs, die Streifenbildung und das Wiederanschmutzverhalten wurde an Fensterscheiben, die durch unterschiedliche Umweitbedingungen auch unterschiedlich angeschmutzt waren, geprüft. Dabei wurden die erfindungsgemässen Fensterreinigungsmittel und ein Vergleichsprodukt wiederum auf unmittelbar nebeneinanderliegenden Flächen angewendet und die Ergebnisse verglichen. Als Fensterscheiben wurden Innenscheiben kleiner Räume, in denen stark geraucht wurde, sowie Aussenscheiben, die starker Verschmutzung durch Strassenverkehr ausgesetzt waren, herangezogen.The cleaning effect, the lightness of the wiping process, the streaking and the re-soiling behavior were tested on window panes, which were also soiled differently by different environmental conditions. The window cleaning agents according to the invention and a comparison product were in turn applied to areas lying directly next to one another and the results were compared. The window panes used were inner panes of small rooms in which there was a lot of smoking, as well as outer panes that were exposed to heavy pollution from road traffic.

Schliesslich wurden die erfindungsgemässen Fensterreinigungsmittel und ein Vergleichsprodukt professionellen Fensterputzern für die Dauer von einigen Wochen zum Gebrauch zur Verfügung gestellt und anschliessend die Erfahrungen beim Gebrauch abgefragt. Die Ergebnisse sind den nachfolgend wiedergegebenen Beispielen zu entnehmen.Finally, the window cleaning agents according to the invention and a comparative product were made available to professional window cleaners for use for a period of a few weeks, and the experience with their use was then queried. The results are shown in the examples given below.

Die Zusammensetzung des Vergleichsproduktes entsprach dabei dem erfindungsgemässen Fensterreiniger, wobei jedoch als Polymeres ein Styrol-Maleinsäureanhydrid-Copolymeres mit einem ungefähren Molgewicht von 2300 eingesetzt wurde, wie es der DE-A-2 220 540 entspricht.The composition of the comparison product corresponded to the window cleaner according to the invention, but a styrene-maleic anhydride copolymer with an approximate molecular weight of 2300 was used as the polymer, as corresponds to DE-A-2 220 540.

Die Anti-Nebelbildung auf Spiegeln wurde verglichen mit einem Produkt gleicher Zusammensetzung, das, jedoch anstelle von POLYOX® mengengleich ein Styrol-Maleinhydrid-Copolymer gemäss der DE-A-2 220 540 enthielt. Beide Produkte lieferten in jeweils 1%iger Lösung gute Antibeschlageffekte. Sodann wurden beide Produkte auf natürlich angeschmutzten Fensterscheiben angewendet. Hierbei erreichte man mit dem erfindungsgemässen Fensterreiniger eine vollkommen streifenfreie Glasfläche, während das Vergleichsprodukt einen deutlichen Schleier hinterliess, der erst durch nachfolgendes Wischen mit klarem Wasser zu beseitigen war. Die beiden Vergleichsprodukte wurden ausserdem für 6 Wochen professionellen Fensterputzern zum Gebrauch gegeben. Die Befragung ergab, dass die erfindungsgemässe Formulierung hinsichtlich Reinigungswirkung, Rückstandsfreiheit, leichter Abwischbarkeit günstiger als das Vergleichsprodukt und als sonstige bisher von ihnen benutzte Mittel beurteilt wurden.The anti-fog formation on mirrors was compared with a product of the same composition which, however, instead of POLYOX® contained the same amount of a styrene-maleic anhydride copolymer according to DE-A-2 220 540. Both products delivered good anti-fog effects in a 1% solution. Then both products were on naturally soiled window panes applied. A completely streak-free glass surface was achieved with the window cleaner according to the invention, while the comparison product left a clear veil which could only be removed by wiping with clear water. The two comparison products were also given to professional window cleaners for use for 6 weeks. The survey revealed that the formulation according to the invention was judged to be more economical than the comparative product in terms of cleaning action, freedom from residues, easier wiping and as other means previously used by them.
