Description

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

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 used for particularly thorough cleaning of heavy soiling, e.g. in industry, in the kitchen and in the sanitary area or for removing film layers based on polymer and / or wax. The basic cleaners are usually used 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, which have a pH value less than 10.5. Due to their relatively low pH, they are also suitable for use on more sensitive floor coverings such as linoleum and rubber. These universal basic cleaners are a mixture of solvents, surfactants, builders, solubilizers and volatile alkalis, either amines or ammonia. The builders used are usually phosphates, citrates, nitrilotriacetic acid (NTA), ethylenediaminetetraacetic acid (EDTA) and carbonates. The basic cleaners known from the prior art are available in a relatively large dilution, since concentration generally leads to separation of the solvents or fails to salt out the builders used. US Pat. No. 5,342,551 describes a composition for removing film layers on floors which contains monoethanolamine citrate, coupling agent and solvent, the pH being between 8.0 and 10 by adding a sufficient amount of monoethanolamine or another alkaline agent. The composition described can contain, for example, disodium isodecylsulfosuccinate as surfactants. However, the cleaning agent composition described is only suitable for removing film layers on floors; thorough cleaning to remove heavy soiling does not lead to satisfactory results.

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 generally have an active concentration of 20% by weight. Depending on the degree of soiling of the surface to be cleaned, these cleaners are used in different dilutions. When developing new cleaning agents, there is an ongoing effort to develop agents that have a higher performance and can therefore be used in lower concentrations.

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 whose cleaning performance exceeds that of conventional basic cleaners both in the removal of old film layers on floors and in the cleaning of heavy soiling.

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 achieves a higher cleaning performance than that of conventional cleaners. In particular, it was found that by using the solvent mixture mentioned as component A), a significant improvement in the cleaning performance than by the individual solvent constituents can also be obtained by adding these individual effects.

Die Komponenten a) und b) können in einem Verhältnis von 1 : 0,5 bis 1 : 10, bevorzugt 1 : 0,5 bis 1 : 2 und besonders bevorzugt 0,9 : 1 bis 1 : 0,9 vorliegen. Als Alkohole der Gruppe b) werden besonders bevorzugt n-Butylglykol, Propylenglykol-n-butylether, n-Butyldiglykol und Gemische der voranstehenden eingesetzt. Die Lösungsmittelkomponenten a) und b) können jeweils in Mengen von 5 bis 40 Gew.-%, besonders bevorzugt 5 bis 30 Gew-%, bezogen auf das fertige Mittel, im erfindungsgemäßen Mittel enthalten sein.According to the invention, the basic cleaner contains a solvent mixture of a) phenoxy alcohol and b) a further alcohol selected from the group consisting of benzyl alcohol, C 2 -C 4 alkyl glycols and ethers of C 1 -C 4 alcohols with (poly) glycols, in particular C 2 -C 4 glycols. Components a) and b) can be present in a ratio of 1: 0.5 to 1:10, preferably 1: 0.5 to 1: 2 and particularly preferably 0.9: 1 to 1: 0.9.

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

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.

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 engruppenverschlossenen C12-C22-Alkoholalkoxylate werden aus den Verbindungen mit der Formel I oder II in an sich bekannter Weise durch Veretherung der endständ gen 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 z. 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 Schritten EP-A 1-0 301 298 und WO 90/3977 verwiesen. Die Alkylglykoside folgen der Formel III,

        R3O[G]x     (III),

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 which can be obtained from alcohols and carbohydrates by the relevant methods of preparative organic chemistry, for example by condensation reactions or transetherification. As a representative of the extensive literature, reference is made here to steps EP-A 1-0 301 298 and WO 90/3977. The alkyl glycosides follow the formula III,

R 3 O [G] x (III),

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), i.e. the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While x must always be an integer in a given compound and here can take on the values x = 1 to 6, the value x is for a certain alkyl glycoside an analytically calculated quantity, which usually represents a fractional number. Alkyl glycosides with an average degree of oligomerization x of 1.1 to 3.0 are preferably used. From an application point of view, those alkyl glycosides are preferred whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.6. Glucose and xylose are preferably used as glycoses.

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.

Der Alkyl- bzw. Alkenylrest R3 leitet sich vorzugsweise von Laurylalkohol, Myristylalkohol, Cetylalkohol, Palmoleylalkohol, Stearylalkohol, Isostearylalkohol oder Oleylalkohol und deren Gemische, etwa Kokosfettalkohol, ab. Weiterhin sind Elaidylalkohol, Petroselinylalkohol, Arachylalkohol, Gadoleylalkohol, Behenylalkohol, Erucylalkohol sowie deren technische Gemische zu nennen.The alkyl or alkenyl radical R 3 is preferably derived from lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol or oleyl alcohol and mixtures thereof, for example coconut oil alcohol. Elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol and their technical mixtures are also to be mentioned.

Die nichtionischen Tenside können in den erfindungsgemäßen Mitteln in Mengen von 1 bis 20 Gew.-%, bevorzugt in Mengen von 1 bis 10 Gew.-%, jeweils bezogen auf das fertige Mittel, enthalten sein.The nonionic surfactants can be present in the compositions according to the invention in amounts of 1 to 20% by weight, preferably in amounts of 1 to 10% by weight, based in each case on the finished composition.

Als weiteren Bestandteil kann der erfindungsgemäße Grundreiniger Seife enthalten. Als Seife eignen sich insbesondere gesättigte Fettsäureseifen, die Salze, insbesondere die Alkalisalze, der Laurinsäure, Myristinsäure, Palmitinsäure oder Stearinsäure, sowie insbesondere aus natürlichen Fettsäuren, z.B. Kokos-, Palmkern- oder Talgfettsäuren, abgeleitete Seifengemische. Die Seifen können in Mengen bis zu 10 Gew.-%, bevorzugt 1 bis 5 Gew.-%, jeweils bezogen auf den fertigen Reiniger, enthalten sein.The basic cleaner according to the invention can contain soap as a further component. Particularly suitable as soap are saturated fatty acid soaps, the salts, in particular the alkali salts, lauric acid, myristic acid, palmitic acid or stearic acid, and in particular from natural fatty acids, e.g. Coconut, palm kernel or tallow fatty acids, derived soap mixtures. The soaps can be present in amounts of up to 10% by weight, preferably 1 to 5% by weight, based in each case on the finished cleaner.

Als reinigungsaktive Bestandteile kann des erfindungsgemäße Mittel weiterhin anionische Tenside enthalten. Geeignete Aniontenside sind z.B.
