Description

Die vorliegende Erfindung betrifft eine Zusammensetzung, die zur Reinigung von Öfen aller Art, insbesondere für Herde, Backöfen und Grillgeräte, geeignet ist.The present invention relates to a composition which is suitable for cleaning ovens of all kinds, in particular for stoves, ovens and grills.

Die derzeit auf dem Markt befindlichen Zusammensetzungen, die für die Reinigung von klassischen Emailleöfen bestimmt sind, weisen im wesentlichen als aktive Bestandteile einerseits einen geeigneten basischen Grundstoff, der auf Fette und angebrannte Rückstände einwirkt, und andererseits Lösungsmittel und organische Wirkstoffe auf, die als Lösungsmittel und Anfeuchte- bzw. Benetzungsmittel wirken. Um eine einfache Handhabung zu ermöglichen, sind die Mischungen meistens als Sprays abgefüllt und können andere Bestandteile wie z. B. Tenside und/oder schäumende Mittel, Verdickungsmittel und Schaumstabilisatoren enthalten. Es ist anzumerken, daß die Verbraucher besonders die Produkte in Form eines stabilen Schaumes schätzen, die den Vorteil haben, den Sprühvorgang sichtbar zu machen.The compositions currently on the market, which are intended for the cleaning of classic enamel stoves, essentially have as active constituents on the one hand a suitable basic base material which acts on fats and burnt-on residues, and on the other hand solvents and organic active substances which act as solvents and Moisturizers or wetting agents work. To enable easy handling, the mixtures are mostly filled as sprays and can contain other components such as. B. surfactants and / or foaming agents, thickeners and foam stabilizers. It should be noted that consumers particularly appreciate the products in the form of a stable foam, which have the advantage of making the spraying process visible.

Die derzeit auf dem Markt befindlichen Reinigungsprodukte für Öfen weisen im wesentlichen, in Gewichtsverhältnissen, 5 bis 10 % Lösungsmittel und 10 bis 15 % basische Grundstoffe auf, die im allgemeinen durch ein Gemisch einer alkalischen Base wie Soda oder Pattasche und eines oder mehrerer Amine, besonders des Monoethanolamins gebildet werden. Solche Produkte sind mit einer zufriedenstellenden Wirksamkeit für die Reinigung der klassischen Emailleöfen entwickelt worden, jedoch nicht für die Reinigung der sogenannten selbstreinigenden Öfen (Katalyse, Pyrolyse).The cleaning products for ovens currently on the market essentially have, in weight ratios, 5 to 10% solvents and 10 to 15% basic raw materials, which are generally characterized by a mixture of an alkaline base such as soda or pattas and one or more amines of monoethanolamine are formed. Such products have been developed with a satisfactory effectiveness for cleaning the classic enamel stoves, but not for cleaning the so-called self-cleaning stoves (catalysis, pyrolysis).

Weiterhin gibt es heute auf dem Markt neben den klassischen Öfen mit Backröhren aus Emaille auch Backöfen aus rostfreiem Stahl, die mit einer Heißluftheizung ausgestattet sind und die entweder als nur "Heißluft-Backöfen oder als gemischte "Heißluft/Grill"-Backöfen ausgeführt sein können. Dabei ist festzustellen, daß die Beschaffenheit der Verkleidungen dieser Öfen (nichtoxidierender Stanl) große Schwierigkeiten bei der Reinigung mit den auf dem Markt bekannten Produkten, wie oben definiert, verursacht und somit die Entwicklung wirksamerer Reinigungszusammensetzung erforderlich macht. Man hat bis zum heutigen Tage den Verbrauchern keine geeigneten Zusammensetzungen anbieten können, die eine zufriedenstellende Reinigung der Öfen mit Umluftbackröhren aus nichtoxidierendem Stahl erlauben.Furthermore, in addition to the classic ovens with enamel tubes, there are also ovens made of stainless steel on the market, which are equipped with hot air heating and which can either be designed as "hot air ovens or as mixed" hot air / grill "ovens. It should be noted that the nature of the cladding of these ovens (non-oxidizing stan) causes great difficulties in cleaning with the products known on the market as defined above, and therefore requires the development of more effective cleaning compositions power. To this day, consumers have not been able to offer suitable compositions which allow the ovens to be cleaned satisfactorily with non-oxidizing steel convection ovens.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diesen Mißstand zu beheben, indem eine neue Zusammensetzung zum Reinigen der Öfen vorgeschlagen wird, die die Vorteile der bekannten Zusammensetzung für die Reinigung von klassischen Emailleöfen aufweist aber gleichzeitig mit der Eigenschaft, daß sie in zufriedenstellender Weise für die Reinigung der neuen Öfen aus nichtioxidierendem Stahl und "Grill/Heißluft"-Backöfen benutzbar ist.The present invention has for its object to remedy this situation by proposing a new composition for cleaning the stoves, which has the advantages of the known composition for cleaning classic enamel stoves, but at the same time with the property that they are satisfactory for the Cleaning the new ovens made of non-oxidizing steel and "grill / hot air" ovens is usable.

Gemäß der Erfindung ist diese Zusammensetzung dadurch gekennzeichnet, daß sie zusätzlich zu einem basischen Grundstoff, welcher eine alkalische Base wie Soda oder Pottasche und/oder ein oder mehrere Amine enthält, 10 bis 30 Gewichtsprozent eines Gemisches aus wenig flüchtigen Lösungsmitteln aufweist, welches zum einen Teil aus Propylenglykolmethylether und zum anderen Teil aus Dipropylenglykolmethylether besteht, wobei das Gewichtsverhältnis Propylenglykolether zu Dipropylenglykolether zwischen 30 : 70 und 90 : 10 liegt.According to the invention, this composition is characterized in that, in addition to a basic base material which contains an alkaline base such as soda or potash and / or one or more amines, 10 to 30% by weight of a mixture of low-volatile solvents, some of which consists of propylene glycol methyl ether and the other part of dipropylene glycol methyl ether, the weight ratio of propylene glycol ether to dipropylene glycol ether being between 30:70 and 90:10.

Die Zusammensetzung gemäß der Erfindung unterscheidet sich also von klassischen Zusammensetzungen gleichen Typs gleichermaßen durch einen höheren Gehalt an Lösungsmittel und durch die besondere Beschaffenheit des Lösungsmittels, welches ausschließlich aus einem Gemisch aus Propylenglykolmethylether und Dipropylenglykolmethylether besteht. Vorzugsweise handelt es sich um die Glykolmonoether.The composition according to the invention therefore differs equally from classic compositions of the same type in that it has a higher solvent content and in the particular nature of the solvent, which consists exclusively of a mixture of propylene glycol methyl ether and dipropylene glycol methyl ether. It is preferably the glycol monoethers.

Bei der Verwendung der erfindungsgemäßen Zusammensetzung als Spray wird eine besonders starke Schaumbildung erreicht.When the composition according to the invention is used as a spray, particularly strong foaming is achieved.

Man hat außerdem besonders zufriedenstellende Ergebnisse bei der Reinigung von Öfen mit Heißluftröhren und mit Röhren aus nichtoxidierbarem Stahl erhalten und bei klassischen Emailleöfen die Wirksamkeit mit dem Ziel einer schnelleren Einwirkung verbessert. Man kann tatsächlich in Zahlen wiedergeben, daß eine derzeit auf dem Markt erhältliche entsprechende Zusammensetzung nach einer Einwirkungszeit von einer Nacht die gleiche Wirkung zeigt, wie die Zusammensetzung gemäß der Erfindung nach einer Einwirkdauer von 30 Minuten aufgrund einer bessseren Lösung der Fette infolge einer geringeren Verdunstung des Lösungsmittels.In addition, particularly satisfactory results have been obtained in the cleaning of furnaces with hot air tubes and with tubes made from non-oxidizable steel, and the effectiveness with classic enamel furnaces has been improved with the aim of acting more quickly. It can actually be stated in figures that a corresponding composition currently available on the market after a contact time of one night has the same effect as the composition according to the invention after a contact time of 30 minutes due to a better solution of the fats due to a lower evaporation of the Solvent.

Entsprechend einer besonderen Ausführungsform der Erfindung weist die Zusammensetzung zwischen 10 und 15 Gewichtsprozent Lösungsmittel auf, wobei die Menge des Propylenglykolethers vorzugsweise etwa 2 bis 4 mal höher ist als die Menge des Dipropylenglykolethers.According to a particular embodiment of the invention, the composition has between 10 and 15 percent by weight of solvent, the amount of propylene glycol ether preferably being about 2 to 4 times higher than the amount of dipropylene glycol ether.

Entsprechend einer anderen Ausführungsform kann die Zusammensetzung zwischen 0,5 und 10 Gew.-% Natriumcarbonat (Soda) aufweisen. Unter Berücksichtigung der Gebrauchssicherheit und zur besseren Vorbeugung von Unfallrisiken durch Kontakt oder Einnahme dieser Produkte, besteht bei den Herstellern seit mehreren Jahren das Bestreben, die maximale Menge der ätzenden und beizenden Stoffe zu vermindern, die in den zur Reinigung von Öfen bestimmten Zusammensetzungen enthalten sind. Das Reinigungsmittel gemäß der Erfindung zeigt seine Wirksamkeit mit einem Natriumcarbonatgehalt bereits unter 2 %, und es ist vorteilhaft, diese Grenze nicht zu überschreiten. In einer besonders vorteilhaften Ausführungsform der Erfindung besteht der basische Grundstoff vorzugsweise aus einem Gemisch von 0,5 bis 2 % Natriumcarbonat und 2 bis 10, vorzugsweise 2 bis 6 Gew.-% Amin, vorzugsweise Monoethanolamin.According to another embodiment, the composition can have between 0.5 and 10% by weight sodium carbonate (soda). Taking into account the safety of use and to better prevent the risk of accidents caused by contact or ingestion of these products, manufacturers have been trying for several years to reduce the maximum amount of caustic and pickling substances contained in the compositions intended for cleaning ovens. The cleaning agent according to the invention shows its effectiveness with a sodium carbonate content already below 2%, and it is advantageous not to exceed this limit. In a particularly advantageous embodiment of the invention, the basic base material preferably consists of a mixture of 0.5 to 2% sodium carbonate and 2 to 10, preferably 2 to 6% by weight of amine, preferably monoethanolamine.

Gemäß einer weiteren Ausführungsform der Erfindung weist die Zusammensetzung zwischen 0,5 und 2 % eines Verdickungsmittels auf, beispielsweise Smectitton. Es wurde festgestellt, daß das Vorhandensein eines Verdickungsmittels in der Zusammensetzung gemäß der Erfindung ein Anhaften des versprühten Produktes an den Ofenwänden erleichtert.According to a further embodiment of the invention, the composition has between 0.5 and 2% of a thickener, for example Smectitton. The presence of a thickener in the composition according to the invention has been found to facilitate adherence of the sprayed product to the furnace walls.

Gemäß einer weiteren Ausführungsform der Erfindung weist die Zusammensetzung bis zu 2 Gew.-%, vorzugsweise 0,1 bis 1 Gew.-% eines grenzflächenaktiven Mittels auf, insbesondere ein Natriumsulfat eines Fettalkohols mit 8 bis 15, vorzugsweise 10 bis 12 C-Atomen, der mit 2 bis 5 Mol Ethylenoxid ethoxyliert ist.According to a further embodiment of the invention, the composition has up to 2% by weight, preferably 0.1 to 1% by weight, of a surface-active agent, in particular a sodium sulfate of a fatty alcohol having 8 to 15, preferably 10 to 12, carbon atoms, which is ethoxylated with 2 to 5 moles of ethylene oxide.

Gemäß einer weiteren Ausführungsform der Erfindung weist die Zusammensetzung bis zu 2 Gew.-%, vorzugsweise 0,1 bis 1 Gew.-% eines schaumstabilisierenden Mittels auf, insbesondere ein Amid einer Fettsäure mit 8 bis 14 C-Atomen oder ein Kopraöl.According to a further embodiment of the invention, the composition has up to 2% by weight, preferably 0.1 to 1% by weight, of a foam-stabilizing agent, in particular an amide of a fatty acid with 8 to 14 carbon atoms or a copra oil.

Beispielexample

Als Beispiel sei die folgende Zusammensetzung mit besonders zufriedenstellender Wirkung angführt, wobei die Anteile der unterschiedlichen Inhaltsstoffe in Gewichtsteilen angegeben sind: Natriumcarbonat 1,5 Monoethanolamin 6 Propylenglykolmethylether 9 Dipropylenglykolmethylether 4,5 Ton vom Smectittyp 1 Fettsäureamid 0,5 Natriumlaurylethersulfat 0,5 Duftstoffe 0,05 Wasser 79,95 As an example, the following composition may be mentioned with a particularly satisfactory effect, the proportions of the different ingredients being given in parts by weight: sodium 1.5 Monoethanolamine 6 Propylene glycol methyl ether 9 Dipropylene glycol methyl ether 4.5 Smectite type clay 1 Fatty acid amide 0.5 Sodium lauryl ether sulfate 0.5 Fragrances 0.05 water 79.95

Es ist zu bemerken, daß sich diese Zusammensetzung von den klassischen Zusammensetzungen nicht nur durch einen höheren Gehalt an Lösungsmitteln und besonders durch deren Beschaffenheit unterscheidet, sondern ebenso durch einen geringeren Gehalt an basischen Grundstoffen, also ätzenden oder agressiven Bestandteilen. Über die oben erwähnten Vorteile hinausgehend zeigt diese Zusammensetung gemäß der Erfindung ebenso den Vorteil, daß sie nicht entflammbar ist, was ein besonders wichtiger Vorteil ist, wenn die Zusammensetzung für ein Spray bestimmt ist.It should be noted that this composition differs from the classic compositions not only by a higher content of solvents and particularly by their nature, but also by a lower content of basic raw materials, that is to say caustic or aggressive components. In addition to the advantages mentioned above, this composition according to the invention also has the advantage that it is non-flammable, which is a particularly important advantage when the composition is intended for a spray.
