Description

"Zusammensetzung zur Reinigung von Öfen" "Composition for cleaning ovens"
Die vorliegende Erfindung betrifft eine Zusammensetzung, die zur Reinigung von Öfen aller Art, insbesondere für Herde, Backöfen und Grillgeräte, ge¬ eignet 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 Rei¬ nigung 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 Lö¬ sungsmittel und organische Wirkstoffe auf, die als Lösungsmittel und An¬ feuchte- bzw. Benetzungsmittel wirken. Um eine einfache Handhabung zu er¬ möglichen, sind die Mischungen meistens als Sprays abgefüllt und können andere Bestandteile wie z. B. Tenside und/oder schäumende Mittel, Ver- dickungsmittel 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 cleaning classic enamel stoves, essentially have as active constituents, on the one hand, a suitable basic raw material, which acts on fats and burnt-on residues, and, on the other hand, solvents and organic active substances, which act as solvents and moistening or wetting agents. In order to make handling easy, the mixtures are mostly filled as sprays and 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 A ine, besonders des Monoethanolamins gebildet werden. Solche Produkte sind mit einer zufriedenstellenden Wirksamkeit für die Reinigung der klas¬ sischen 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 composed of a mixture of an alkaline base such as soda or pattas and one or more amino acids, especially of monoethanolamine. 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 Back¬ röhren aus Emaille auch Backöfen aus rostfreiem Stahl, die mit einer Hei߬ luftheizung 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 Stahl) große Schwierigkeiten bei der Reinigung mit den auf dem Markt bekannten Produkten, wie oben definiert, verursacht und so¬ mit 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 nichtoxidierende Stahl erlauben.Furthermore, in addition to the classic ovens with baking tubes made of enamel, there are also ovens made of stainless steel on the market which are equipped with hot air heating and which are either only available 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 steel) causes great difficulties in cleaning with the products known on the market, as defined above, and thus requires the development of more effective cleaning compositions makes. To this day, it has not been possible to offer consumers 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 vorgeschla¬ gen wird, die die Vorteile der bekannten Zusammensetzung für die Reinigung von klassischen Emailleöfen aufweist aber gleichzeitig mit der Eigen¬ schaft, daß sie in zufriedenstellender Weise für die Reinigung der neuen Öfen aus nichtioxidierendem Stahl und "Grill/Heißluft"-Backöfen benutzbar ist.The object of the present invention is to remedy this problem by proposing a new composition for cleaning the furnaces which has the advantages of the known composition for cleaning classic enamel furnaces but at the same time has the property that it is in can be used satisfactorily for cleaning the new non-oxidizing steel and "grill / hot air" ovens.
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 flüchtigem Lösungsmittel auf¬ weist, welches zum einen Teil mindestens einen Propylenglykolether und zum anderen Teil mindestens einen Dipropylenglykolether enthält, 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, it has 10 to 30% by weight of a mixture of low-volatile solvent which is used for one part contains at least one propylene glycol ether and the other part contains at least one dipropylene glycol 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 klas¬ sischen Zusammensetzungen gleichen Typs gleichermaßen durch einem höheren Gehalt an Lösungsmittel und durch die besondere Beschaffenheit des Lö¬ sungsmittels, welches ausschließlich aus einem Gemisch aus Propylenglykol¬ ether und Dipropylenglykolether besteht. Vorzugsweise handelt es sich um die Glykolmonoether. Man kann einen weiten Bereich dieser Ether benutzen, ohne die Erfindung zu verlassen; die Wahl der tatsächlich benutzten Ether wird in erster Linie durch Überlegungen bezüglich Wirtschaftlichkeit und Lösungsfähigkeit bestimmt.The composition according to the invention thus differs from classic compositions of the same type equally 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 ether and dipropylene glycol ether. It is preferably the glycol monoethers. A wide range of these ethers can be used without departing from the invention; The choice of the ether actually used is primarily determined by considerations regarding economy and solvency.
Man hat beispielsweise sehr zufriedenstellende Ergebisse erzielt, wenn man in Verbindung mit Dipropylenglykolmethylether ein Gemisch des n- oder t- Butylethers und des Methylethers des Propylenglykols im Verhältnis 30 : 70 bis 70 : 30 verwendete. Gemäß einer bevorzugten Ausgestaltung der Erfindung wird eine besonders starke Schaumbildung bei der Verwendung als Spray erreicht, wenn das Lö¬ sungsmittel durch ein Gemisch aus Dipropylenglykol ethylether und Pro- pylenglykolmethylether gebildet wird.For example, very satisfactory results have been achieved if a mixture of the n- or t-butyl ether and the methyl ether of the propylene glycol in a ratio of 30:70 to 70:30 is used in conjunction with dipropylene glycol methyl ether. According to a preferred embodiment of the invention, particularly strong foaming when used as a spray is achieved if the solvent is formed by a mixture of dipropylene glycol ethyl ether and propylene glycol methyl ether.
Man hat außerdem besonders zufriedenstellende Ergebnisse bei der Reinigung von Öfen mit Heißluftröhren und mit Röhren aus nichtoxidierbare Stahl erhalten und bei klassischen Emailleöfen die Wirksamkeit mit dem Ziel ei¬ ner schnelleren Einwirkung verbessert. Man kann tatsächlich in Zahlen wiedergeben, daß eine derzeit auf dem Markt erhältliche entsprechende Zu¬ sammensetzung nach einer Einwirkungszeit von einer Nacht die gleiche Wir¬ kung zeigt, wie die Zusammensetzung gemäß der Erfindung nacir einer Ein¬ wirkdauer 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 ovens with hot air tubes and with tubes made of non-oxidizable steel, and the effectiveness with classic enamel ovens has been improved with the aim of a faster action. In fact, it can be shown 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 less evaporation of the solvent.
Entsprechend einer besonderen Ausführungsform der Erfindung weist die Zu¬ sammensetzung 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 the propylene glycol ether preferably being about 2 to 4 times higher than the amount of the dipropylene glycol ether.
Entsprechend einer anderen Ausführungsform kann die Zusammensetzung zwi¬ schen 0,5 und 10 Gew.-% Natriumcarbonat (Soda) aufweisen. Unter Berück¬ sichtigung der Gebrauchssicherheit und zur besseren Vorbeugung von Un- fal irisiken 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 Natriumcarbonatge- halt bereits unter 2 %, und es ist vorteilhaft, diese Grenze nicht zu überschreiten. In einer besonders vorteilhaften Ausführungsform der Er¬ findung besteht der basische Grundstoff vorzugsweise aus einem Gemisch von 0,5 bis 2 % Natriumcarbonat und 2 bis 10, vorzugsweise 2 bis 6 Gew.-% A in, 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 by contacting or taking these products, manufacturers have been trying for several years to reduce the maximum amount of the caustic and pickling substances used in cleaning ovens certain compositions are included. 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 A in, preferably monoethanolamine.
Gemäß einer weiteren Ausführungsform der Erfindung weist die Zusammen¬ setzung zwischen 0,5 und 2 % eines Verdickungsmittels auf, beispielsweise Smectitton. Es wurde festgestellt, daß das Vorhandensein eines Ver¬ dickungsmittels 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. It has been found that the presence of a thickening agent in the composition according to the invention facilitates adhesion of the sprayed product to the furnace walls.
Gemäß einer weiteren Ausführungsform der Erfindung weist die Zusammen¬ setzung bis zu 2 Gew.-%, vorzugsweise 0,1 bis 1 Gew.-% eines grenz¬ flächenaktiven Mittels auf, insbesondere ein Natriumsulfat eines Fettal¬ kohols 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 with 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 Zusammen¬ setzung bis zu 2 Gew.-%, vorzugsweise 0,1 bis 1 Gew.-% eines schaumstabi¬ lisierenden 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 Copra oil.

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, al-;o ätzenden oder agressiven Bestandteilen. Über die oben erwähnten Vorteile hinaus¬ gehend 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, al-, o corrosive 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 if the composition is intended for a spray.
