Description

Die vorliegende Erfindung betrifft einen wasserhaltigen Grundreiniger, der als aktive Substanzen Lösungsmittel und nichtionische Tenside enthält.The present invention relates to a water-based basic cleaner, which as an active Contains substances solvents and non-ionic surfactants.

Grundreiniger sind ein spezieller Reinigungsmitteltyp, der zu einer besonders gründlichen Reinigung von starken Verschmutzungen, z.B. in der Industrie, in der Küche und im Sanitärbereich oder zur Entfernung von Filmschichten auf Polymer und/oder Wachsbasis eingesetzt wird. Üblicherweise werden die Grundreiniger in einer Verdünnung von 1 : 1 bis 1 : 10 eingesetzt.Basic cleaners are a special type of detergent that is one of a kind thorough cleaning of heavy soiling, e.g. in the industry, in the Kitchen and sanitary areas or for removing film layers on polymer and / or wax base is used. The basic cleaners are usually in a dilution of 1: 1 to 1:10.

Zu den Grundreinigern zählen auch die sogenannten Universalgrundreiniger, die einen pH-Wert kleiner als 10,5 aufweisen. Sie sind aufgrund ihres relativ niedrigen pH-Wertes auch zum Einsatz auf empfindlicheren Bodenbelägen, wie Linoleum und Gummi, geeignet. Diese Universalgrundreiniger stellen eine Mischung aus Lösungsmitteln, Tensiden, Gerüststoffen, Lösevermittlern und leichtflüchtigen Alkalien, entweder Aminen oder Ammoniak, dar. Als Gerüststoffe werden üblicherweie Phosphate, Citrate, Nitrilotriessigsäure (NTA), Ethylendiamintetraesssigsäure (EDTA) und Carbonate eingesetzt. Die aus dem Stand der Technik bekannten Grundreiniger liegen in einer relativ großen Verdünnung vor, da eine Aufkonzentrierung in der Regel zur Separierung der Lösungsmittel führt oder an einer Aussalzung der verwendeten Gerüststoffe scheitert. In dem US-Patent 5, 342, 551 wird eine Zusammensetzung zum Entfernen von Filmschichten auf Böden beschrieben, die Monoethanolamin-Citrat, Kupplungsmittel und Lösungsmittel enthält, wobei der pH-Wert zwischen 8,0 und 10 durch Zugabe einer ausreichenden Menge von Monoethanolamin oder einem anderen alkalischen Mittel gehalten wird. Als Tenside kann die beschriebene Zusammensetzung z.B. Dinatriumisodecylsulfosuccinat enthalten. Die beschriebene Reinigungsmittelzusammensetzung ist allerdings nur zum Entfernen von Filmschichten auf Böden geeignet, eine gründliche Reinigung zur Entfernung von starken Verschmutzungen führt nicht zu befriedigenden Ergebnissen. The basic cleaners also include the so-called universal basic cleaners, the have a pH value less than 10.5. They are due to their relatively low pH value also for use on more sensitive floor coverings, such as linoleum and rubber, suitable. These universal basic cleaners are a mixture of solvents, Surfactants, builders, solubilizers and volatile alkalis, either amines or ammonia. The builders are usually Phosphates, citrates, nitrilotriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA) and carbonates are used. The known from the prior art Basic cleaners are available in a relatively large dilution because they are concentrated usually leads to separation of the solvents or salting out of the builders used fails. In U.S. Patent 5,342,551 describes a composition for removing film layers on floors, which contains monoethanolamine citrate, coupling agent and solvent, the pH between 8.0 and 10 by adding a sufficient amount of monoethanolamine or other alkaline agent. As surfactants can the composition described e.g. Disodium isodecyl sulfosuccinate contain. However, the detergent composition described is only suitable for removing film layers on floors, thorough cleaning the removal of heavy soiling does not lead to satisfactory results.

De DE-A-42 43 468 beschreibt ein wäßriges Reinigungsmittel, welches in unverdünntem Zustand einen pH-Wert im Bereich zwischen 5 und 9 aufweist und das 1 bis 25 Gew.-% an Tensid aus den Klassen der nichtionischen und der synthetischen anionischen Tenside sowie 0,1 bis 12 Gew.% an Alkohol aus der Gruppe Benzylalkohol,2-Phenoxyethanol, 2-Phenylethanol und deren Gemische enthält. Das Reinigungsmittel dient in unverdünntem Zustand zur Reinigung harter Oberflächen, nach Verdünnen mit Wasser im Gewichtsverhältnis 1 : 3 bis 1 : 500 zur Reinigung textiler Beläge oder harter Oberflächen. De DE-A-42 43 468 describes an aqueous cleaning agent which in undiluted state has a pH in the range between 5 and 9 and the 1 to 25 wt .-% of surfactant from the classes of nonionic and synthetic anionic surfactants and 0.1 to 12% by weight of alcohol from the Group benzyl alcohol, 2-phenoxyethanol, 2-phenylethanol and their mixtures contains. The detergent is used undiluted for cleaning hard Surfaces, after dilution with water in a weight ratio of 1: 3 to 1: 500 for cleaning textile coverings or hard surfaces.

Die üblichen Universalgrundreiniger haben in der Regel eine Aktivkonzentration von 20 Gew.-%. Diese Reiniger werden, in Abhängigkeit vom Verschmutzungsgrad der zu reinigenden Fläche, in unterschiedlichen Verdünnungen eingesetzt. Bei der Entwicklung von neuen Reinigungsmitteln geht das Bestreben ständig dahin, Mittel zu entwickeln, die eine höhere Leistungsfähigkeit aufweisen und somit in geringeren Konzentrationen eingesetzt werden können.The usual universal basic cleaners usually have an active concentration of 20% by weight. These cleaners are, depending on the degree of contamination the surface to be cleaned, used in different dilutions. In the Development of new detergents is constantly striving to be means to develop, which have a higher performance and thus in lower Concentrations can be used.

Demgemäß lag der vorliegenden Erfindung die Aufgabe zugrunde, einen Grundreiniger zur Verfügung zu stellen, dessen Reinigungsleistung sowohl bei der Entfernung von alten Filmschichten auf Böden als auch bei der Reinigung von starken Verschmutzungen die von herkömmlichen Grundreinigern übersteigt.Accordingly, the object of the present invention was to provide a basic cleaner to provide its cleaning performance both at removal of old film layers on floors as well as when cleaning strong ones Soiling that exceeds that of conventional basic cleaners.

    Überraschenderweise wurde festgestellt, daß das erfindungsgemäße Reinigungsmittel eine höhere Reinigungsleistung als die der herkömmlichen Reiniger erreicht. Insbesondere wurde festgestellt, daß durch die Verwendung des als Komponente A) genannten Lösungsmittelgemisches eine deutliche Verbesserung der Reinigungsleistung als durch die einzelnen Lösungsmittelbestandteile auch als durch die Addition dieser Einzelwirkungen erhalten werden kann.Surprisingly, it was found that the cleaning agent according to the invention a higher cleaning performance than that of conventional cleaners reached. In particular, it was found that by using the as Component A) solvent mixture called a significant improvement the cleaning performance as by the individual solvent components also as can be obtained by adding these individual effects.

The solvent components a) and b) can each be present in the inventive composition in amounts of 5 to 40% by weight, particularly preferably 5 to 30% by weight, based on the finished composition.

    Als weitere Bestandteile enthält der Grundreiniger erfindungsgemäß wenigstens ein nichtionisches Tensid aus der Gruppe der C12-C22-Alkoholalkoxylate, der endgruppenverschlossenen C12-C22-Alkoholalkoxylate und der Alkylpolyglykoside.According to the invention, the basic cleaner contains at least one nonionic surfactant from the group of the C 12 -C 22 alcohol alkoxylates, the end-capped C 12 -C 22 alcohol alkoxylates and the alkyl polyglycosides as further constituents.

    wherein R 2 and o can have the same meaning as R 1 and m in formula I and n stands for numbers from 0.5 to 2.

    Sie können durch Alkoxylierung von C12-C22-Alkoholen erhalten werden können. Als Alkoxylate werden insbesondere die Ethoxylate und die gemischten Ethoxylate/Propoxylate eingesetzt. Geeignete C12-C22-Alkohole sind beispielsweise die nativen Fettalkohole auf pflanzlicher Basis wie z.B. Laurylalkohol, Myristylalkohol, Cetylalkohol, Stearylalkohol, Behenalkohol, Oleylalkohol, Elaidylalkohol, Ricinolalkohol, Linoleylalkohol, Linolenylalkohol sowie deren natürlich vorkommenden Gemische, wie Kokosfettalkohol, Palm- und Palmkernfettalkohol oder auch Erdnussfettalkohol. Es können auch die technischen Gemische, wie sie beispielsweise im Verlauf der Hydrierung von technischen Fettsäuremethylestern oder im Verlauf der Hydrierung von Aldehyden aus der Roelen'schen Oxosynthese anfallen, eingesetzt werden. Besonders bevorzugt werden C12-C16-Fettalkoholethoxylate mit einem Alkoxylierungsgrad von 5 bis 10 eingesetzt. They can be obtained by alkoxylation of C 12 -C 22 alcohols. In particular, the ethoxylates and the mixed ethoxylates / propoxylates are used as alkoxylates. Suitable C 12 -C 22 alcohols are, for example, the native fatty alcohols based on plants, such as, for example, lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, behen alcohol, oleyl alcohol, elaidyl alcohol, ricinol alcohol, linoleyl alcohol, linolenyl alcohol and their naturally occurring mixtures, such as coconut oil palm oil or peanut fatty alcohol. It is also possible to use the technical mixtures which are obtained, for example, in the course of the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis. C 12 -C 16 fatty alcohol ethoxylates with a degree of alkoxylation of 5 to 10 are particularly preferably used.

    Die endgruppenverschlossenen C12-C22-Alkoholalkoxylate werden aus den Verbindungen mit der Formel I oder II in an sich bekannter Weise durch Veretherung der endständigen OH-Gruppe mit z. B. einem niederen Alkohol oder Alkylhalogenid erhalten. Bevorzugt wird als endständige Gruppe eine Butylgruppe eingesetzt.The end-capped C 12 -C 22 alcohol alkoxylates are prepared from the compounds of the formula I or II in a manner known per se by etherification of the terminal OH group with, for. B. a lower alcohol or alkyl halide. A butyl group is preferably used as the terminal group.

    Als weitere nichtionische Tenside kommen die Alkylglykoside in Frage. Alkylglykoside (APG) stellen bekannte Stoffe dar, die nach den einschlägigen Verfahren der präparativen organischen Chemie, beispielsweise durch Kondensationsreaktionen oder Umetherungen aus Alkoholen und Kohlenhydraten, erhalten werden können. Stellvertretend für das umfangreiche Schrifttum sei hier auf die Schriften EP-A 1-0 301 298 und WO 90/3977 verwiesen. Die Alkylglykoside folgen der Formel III, R3O[G]x in der R3 für eine linearen oder verzweigten, gesättigten oder ungesättigten Alkylrest mit 6 bis 22 Kohlenstoffatomen, [G] für einen glykosidisch gebundenen Zucker und x für eine Zahl von 1 bis 10 steht.The alkyl glycosides are suitable as further nonionic surfactants. Alkyl glycosides (APG) are known substances that can be obtained from alcohols and carbohydrates by the relevant methods of preparative organic chemistry, for example by condensation reactions or transetherification. As representative of the extensive literature, reference is made here to the documents EP-A 1-0 301 298 and WO 90/3977. The alkyl glycosides follow the formula III, R 3 O [G] x in which R 3 is a linear or branched, saturated or unsaturated alkyl radical having 6 to 22 carbon atoms, [G] is a glycosidically bound sugar and x is a number from 1 to 10.

    Die Indexzahl x in der allgemeinen Formel III gibt den Oligomerisierungsgrad (DP-Grad) an, d.h. die Verteilung von Mono- und Oligoglykosiden, und steht für eine Zahl zwischen 1 und 10. Während x in einer gegebenen Verbindung stets ganzzahlig sein muß und hier vor allem die Werte x = 1 bis 6 annehmen kann, ist der Wert x für ein bestimmtes Alkylglykosid eine analytisch ermittelte rechnerische Größe, die meistens eine gebrochene Zahl darstellt. Vorzugsweise werden Alkylglykoside mit einem mittleren Oligomerisierungsgrad x von 1,1 bis 3,0 eingesetzt. Aus anwendungstechnischer Sicht sind solche Alkylglykoside bevorzugt, deren Oligomerisierungsgrad kleiner als 1,7 ist und insbesondere zwischen 1,2 und 1,6 liegt. Als Glykosen werden vorzugsweise Glucose und Xylose verwendet.The index number x in the general formula III indicates the degree of oligomerization (DP degree) on, i.e. the distribution of mono- and oligoglycosides, and stands for one Number between 1 and 10. While x is always an integer in a given connection must be and here can assume the values x = 1 to 6, the value x for a certain alkyl glycoside, an analytically calculated quantity, the mostly represents a fractional number. Alkyl glycosides are preferably used an average degree of oligomerization x of 1.1 to 3.0 is used. For application technology In view of such alkyl glycosides are preferred, their degree of oligomerization is less than 1.7 and is in particular between 1.2 and 1.6. As glycoses glucose and xylose are preferably used.

    Der Alkyl- bzw. Alkenylrest R3 kann sich von primären Alkoholen mit 6 bis 22, vorzugsweise 12 bis 18 Kohlenstoffatomen ableiten. Typische Beispiele sind Capronalkohol, Caprylalkohol, Caprinalkohol und Undecylalkohol sowie deren technische Gemische, wie sie beispielsweise im Verlauf der Hydrierung von technischen Fettsäuremethylestern oder im Verlauf der Hydrierung von Aldehyden aus der Roelen'schen Oxosynthese anfallen. The alkyl or alkenyl radical R 3 can be derived from primary alcohols having 6 to 22, preferably 12 to 18, carbon atoms. Typical examples are capronic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as those obtained in the course of the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis.
