Description
Die vorliegende Erfindung betrifft die Verminderung der Korrosivität von Hypochlorit an Metalloberflächen beim Einsatz hypochlorit-haltiger flüssiger Reinigungsmittel zur Reinigung von Metalloberflächen.The The present invention relates to the reduction of corrosivity of hypochlorite on metal surfaces when using hypochlorite-containing liquid detergent for Cleaning of metal surfaces.
Reinigungsmittel für harte Oberflächen, beispielsweise Küchen- und Badezimmerreiniger, sind in der Vergangenheit hoch abrasive Pulver gewesen, die gegebenenfalls geringe Mengen an Tensiden enthielten und zutreffend als Scheuerpulver bezeichnet wurden. Sie waren agressiv nicht nur zur Hand des Benutzers, sondern auch zu der Oberfläche, mit der sie zu Reinigungszwecken in Kontakt gebracht wurden. In einigen Fällen wurde ein Bleichmittel in derartige Scheuerpulver eingearbeitet, um Anschmutzungen oxidativ aufzubrechen und dadurch ihre Entfernbarkeit zu erleichtern. Auch wenn moderne Abrasivreiniger inzwischen deutlich hautfreundlicher in ihrer Zusammensetzung sind, verlassen sich diese Reiniger dennoch im wesentlichen auf die Wirkung des Abrasivstoffs, um Anschmutzungen zu entfernen, zu denen insbesondere auch Seifenablagerungen, die in der Regel im wesentlichen aus der persönlichen Hygiene stammen, von harten Oberflächen, wie beispielsweise von Badezimmerkacheln oder Waschbecken, zu entfernen.cleaning supplies for hard Surfaces, for example, kitchen and bathroom cleaners, have been highly abrasive in the past Powder containing possibly small amounts of surfactants and properly referred to as scouring powder. They were aggressive not only to the user's hand, but also to the surface, with they were brought into contact for cleaning purposes. In some Cases became a bleaching agent incorporated into such scouring powder to stains break up oxidatively and thereby facilitate their removability. Even if modern abrasive cleaners are now much more skin-friendly in their composition, these cleaners still rely essentially on the effect of the abrasive to stains to remove, in particular soap deposits, the usually derived essentially from personal hygiene, from hard surfaces, such as bathroom tiles or sinks.
Zur Entfernung der Anschmutzungen wird üblicherweise nach der Anwendung des Reinigungsmittels ein Nachwischen mit einem feuchten oder auch trockenen Tuch erforderlich. Erstrebenswert ist außerdem, daß das Reinigungsmittel die auf der harten Oberfläche befindliche Anschmutzung durchdringt und so das Abheben der Anschmutzung von der Oberfläche erleichtert. Natriumhypochlorit ist bekannt als hoch effektives Bleichmittel und wird seit langem, gegebenenfalls zusammen mit Seifen und/oder synthetischen Tensiden, zur Entfernung von Flecken und allen Arten von Anschmutzungen bei der Wäsche von Textilien wie auch beim Reinigen harter Oberflächen benutzt. Es wird normalerweise in Konzentrationen von etwa 2 bis 10 Gew.-% in Wasser für die Verwendung in Haushalten vertrieben. Während man bein Einsatz von hypochlorit haltigen Mitteln eine ausgezeichnete Desinfektionsleistung und sehr gute Reinigungsergebnisse an harten Oberflächen erzielt, beobachtet man an empfindlichem Reinigungsgut in einigen Fällen eine Veränderung der Oberfläche. Diese kann von einer leichten Beeinträchtigung des optischen Eindrucks bis hin zum Auftreten von Vertiefungen in der Oberfläche oder sogar Lochfraß bestehen, wobei schwere Fälle normalerweise nur bei unsachgemäßer Anwendung des Mittels auftreten.to Removal of stains is usually after application of the detergent, a wipe with a damp or too dry cloth required. It is also desirable that this Cleaning agent is the soiling on the hard surface penetrates and so facilitates the lifting of the dirt from the surface. Sodium hypochlorite is known as a highly effective bleaching agent and will be for a long time, possibly together with soaps and / or synthetic surfactants, for the removal of stains and all kinds stains on the laundry of textiles as well as when cleaning hard surfaces. It is normally used in concentrations of about 2 to 10% by weight. in water for the use in households sold. While using leg Hypochlorite-containing agents provide excellent disinfecting performance and achieves very good cleaning results on hard surfaces, one observes on sensitive items in some cases one change the surface. These may be of a slight impairment the visual impression up to the appearance of depressions in the surface or even pitting, being severe cases usually only if used improperly of the agent.
Zu den hier angesprochenen empfindlichen Oberflächen gehören insbesondere solche aus Metall, beispielsweise Stahl-Oberflächen, wie sie etwa in Küchenspülen, als Gehäuseoberflächen von Haushaltsmaschinen oder Verkleidungen von Küchen- oder Badezimmerschränken zu finden sind. Bei der Reinigung solcher Oberflächen besteht die Gefahr, daß es durch die Metallkorrosivität des Hypochlorits zu Schädigungen der Oberfläche kommen kann, insbesondere wenn man ein normalerweise nach Verdünnen mit Wasser anzuwendendes Mittel unverdünnt auf die Metalloberfläche aufbringt und dort längere Zeit beläßt.To The sensitive surfaces mentioned here include in particular those Metal, such as steel surfaces, such as in kitchen sinks, as Housing surfaces of Appliances or paneling of kitchen or bathroom cabinets are found. When cleaning such surfaces, there is a risk that it is through the metal corrosiveness of hypochlorite to damage the surface can come, especially if you usually have to dilute with a Apply water to be applied undiluted to the metal surface and there longer Time leaves.
Überraschenderweise wurde nun gefunden, dass die Anpassung beziehungsweise die gezielte Auswahl der sonstigen Inhaltsstoffe hypochlorithaltiger Reinigungsmittel das Korrosionsverhalten positiv beeinflußt.Surprisingly has now been found that the adaptation or the targeted Selection of other ingredients of hypochlorite detergents the corrosion behavior positively influenced.
Gegenstand der vorliegenden Erfindung ist die Verwendung einer Kombination aus Alkalihydroxid, Alkalisilikat und Alkyl-(Alkoxy)n-sulfat mit n = 0,5 bis 10 in einem Hypochlorit-enthaltenden wäßrigen flüssigen Reinigungsmittel zur Verminderung der Korrosivität von Hypochlorit an Metalloberflächen. Vorzugsweise ist dabei die Metalloberfläche eine Stahl-Oberfläche, da dann der Verbesserungseffekt der erfindungsgemäß verwendeten Kombination besonders ausgeprägt ist. Die erfindungsgemäß verwendete Kombination ist vorzugsweise Bestandteil des hypochlorithaltigen Reinigungsmittels.The present invention is the use of a combination of alkali metal hydroxide, alkali metal silicate and alkyl (alkoxy) n- sulfate with n = 0.5 to 10 in a hypochlorite-containing aqueous liquid detergent to reduce the corrosivity of hypochlorite on metal surfaces. Preferably, the metal surface is a steel surface, since then the improvement effect of the combination used in the invention is particularly pronounced. The combination used according to the invention is preferably a constituent of the hypochlorite-containing cleaning agent.
In einer bevorzugten Ausführungsform der Erfindung enthält das Reinigungsmittel 0,5 Gew.-% bis 10 Gew.-%, insbesondere 2 Gew.-% bis 5,5 Gew.-% Alkalihypochlorit. Obzwar auch andere Alkalihypochlorite, wie beispielsweise Kaliumhypochlorit, brauchbar sind, ist es doch bevorzugt, erfindungsgemäß Natriumhypochlorit einzusetzen. In handelsüblichen wäßrigen Natriumhypochlorit-Lösungen sind oft beträchtliche Mengen an Chlorid-Salzen enthalten. Diese können ohne weiteres zur Herstellung erfindungsgemäß korrosionsverbesserter Mittel verwendet werden, so dass man auf den Einsatz von hochreinem NaOCl nicht notwendigerweise angewiesen ist.In a preferred embodiment of the invention the cleaning agent 0.5 wt .-% to 10 wt .-%, in particular 2 wt .-% to 5.5% by weight alkali hypochlorite. Although other alkali metal hypochlorites, such as potassium hypochlorite, for example, it is preferable According to the invention sodium hypochlorite use. In commercial aqueous sodium hypochlorite solutions are often considerable Contain amounts of chloride salts. These can be readily manufactured According to the invention improved corrosion Means are used, so that one on the use of high purity NaOCl is not necessarily reliant.
Die hypochlorithaltigen Mittel sind alkalisch, wobei erfindungsgemäß bevorzugt ist, wenn das Reinigungsmittel mehr als 0 Gew.-% bis zu 5 Gew.-%, insbesondere 0,1 Gew.-% bis 2 Gew.-% Alkalihydroxid enthält.The hypochlorite-containing agents are alkaline, and preferred according to the invention if the cleaning agent is more than 0% by weight up to 5% by weight, in particular 0.1 wt .-% to 2 wt .-% alkali metal hydroxide.
Vorzugsweise sind mehr als 0 Gew.-% bis zu 5 Gew.-%, insbesondere 0,1 Gew.-% bis 2,5 Gew.-% Alkalisilikat in dem Mittel enthalten. Dadurch wird nicht nur das Korrosionsverhalten verbessert, sondern auch die Lagerstabilität des Hypochlorits erhöht.Preferably are more than 0 wt .-% up to 5 wt .-%, in particular 0.1 wt .-% to 2.5% by weight of alkali silicate in the composition. This will not only improves the corrosion behavior, but also the storage stability of the hypochlorite elevated.
Eine weitere Komponente der erfindungsgemäß verwendeten Kombination ist ein Tensid in Form eines Alkyl-(Alkoxy)n-sulfats, das auch als Alkylethersulfat bezeichnet werden kann und durch Umsetzung von Alkoholen (vorzugsweise mit 6 bis 22 Kohlenstoffatomen) mit Alkylenoxiden, insbesondere Ethylenoxid, und anschließende Sulfatierung und Neutralisation, insbesondere mit alkalischen Alkalisalzen wie Alkalihydroxiden, erhältlich ist. In Frage kommt insbesondere ein mit 2 Equivalenten Ethylenoxid alkoxyliertes C12-14-Fettalkoholethersulfat. Alkyl-(Alkoxy)n-sulfat ist vorzugsweise in dem Reinigungsmittel von mehr als 0 Gew.-% bis zu 5 Gew.-% enthalten. Das Alkyl-(Alkoxy)n-sulfat weist vorzugsweise eine C8-18-, insbesondere C12-16-Alkylgruppe, -OCH2CH2- und/oder -OCHCH3CH2- Alkoxygrupppe(n) auf, wobei n vorzugsweise eine Zahl von 1 bis 6, insbesondere 2 bis 5 ist.Another component of the combination used in the invention is a surfactant in the form of an alkyl (alkoxy) n- sulfate, which may also be referred to as alkyl ether sulfate and by reacting alcohols (preferably having 6 to 22 carbon atoms) with alkylene oxides, in particular ethylene oxide, and subsequent Sulfation and neutralization, especially with alkaline alkali metal salts such as alkali metal hydroxides, is available. In question is in particular a 2 equivalents of ethylene oxide alkoxylated C 12-14 fatty alcohol ether sulfate.

Phosphonogruppen-aufweisende Polyacrysäuren, die auch in der Form
ihrer Alkalisalze vorliegen können.
Die Einarbeitung derartiger Komplexbildner führt überraschenderweise zu besonders
gutem Glanzerhalt der behandelten harten Oberflächen. Dies wird nicht beobachtet,
wenn man stattdessen andere Komplexbildner, beispielsweise Methylglycindiessigsäure oder
Nitrilotriessigsäure,
einsetzt. Aminoxidphosphonsäuren
werden normalerweise durch Oxidation von Aminoalkylphosphonsäuren hergestellt.
