Abstract
Description
Zum maschinellen Reinigen von Geschirr werden bekanntlich alkalisch eingestellte Reinigungsmittelgemische verwendet, die im wesentlichen aus anorganischen Salzen wie Alkaliphosphaten, Alkalisilikaten und Alkalicarbonaten und aktivchlorabspaltenden Verbindungen bestehen und die zur Verbesserung der Benetzung gegebenenfalls noch geringe Zusätze eines schwachschäumenden nichtionischen Tensids enthalten. Diese Gemische besitzen bei üblichen Reinigungstemperaturen von 55 °C bis 65 °C im allgemeinen ein gutes Reinigungsvermögen gegenüber allen Anschmutzungen. Schwierigkeiten bei der Reinigung werden allerdings dann beobachtet, wenn es sich bei den Anschmutzungen um angebrannte oder stark angetrocknete, eiweiß- und/oder stärkehaltige Speisereste sowie um weiße beziehungsweise graue Beläge auf dem Spülgut handelt, die im wesentlichen auf alkaliunlösliche, anorganische Calciumsalze zurückzuführen sind und zum einen aus den Speisen selbst, zum anderen aus dem bei der Zubereitung der Speisen verwendeten Wasser stammen. Diese Anschmutzungen werden beim maschinellen Reinigungsprozeß nicht immer vollständig beseitigt, was zu Reklamationen seitens der Anwender führen kann, oder diese dazu veranlaßt, dieses Spülgut nicht in der Maschine zu reinigen.As is known, alkaline cleaning agent mixtures are used for the automatic cleaning of dishes, which essentially consist of inorganic salts such as alkali phosphates, alkali silicates and alkali carbonates and active chlorine-releasing compounds and which, in order to improve the wetting, may contain minor additions of a low-foaming nonionic surfactant. At normal cleaning temperatures of 55 ° C to 65 ° C, these mixtures generally have good cleaning properties against all types of soiling. Difficulties with cleaning are observed, however, if the soiling is burnt or heavily dried, protein and / or starchy food residues as well as white or gray deposits on the wash ware, which are essentially due to alkali-insoluble, inorganic calcium salts and on the one hand come from the food itself, on the other hand from the water used in the preparation of the food. These stains are not always completely removed in the machine cleaning process, which can lead to complaints from the user or cause them not to wash these items in the machine.
Der Erfindung lag daher die Aufgabe zugrunde, ein Vorbehandlungs- oder Einweichmittel aufzufinden, das leicht anwendbar ist und zur vollständigen, selbsttätigen Entfernung von Problemanschmutzungen im maschinellen Reinigungsprozeß führt. Aus der US-Patentschrift 4 116 851 sind zwar pastöse thixotrope, stark alkalische Topfreinigungsmittel bekannt, die verschiedene Verdickungsmittel sowie Aktivchlorverbindungen enthalten, wobei die Mittel bei der Anwendung auf das zu reinigende Gut aufgetragen und mit Wasser überschichtet werden, aufgrund ihrer Gelstruktur längere Zeit auf der Kontaktstelle verbleiben und daher besonders nachhaltig wirken. Dieser Patentschrift war jedoch nicht zu entnehmen, daß sich Mittel, wie sie in der vorstehenden Erfindung beschrieben sind, als Vorbehandlungs- oder Reinigungsmittel bei der Anwendung in Geschirrspülmaschinen eignen würden.The invention was therefore based on the object of finding a pretreatment or soaking agent which is easy to use and leads to the complete, automatic removal of problem soils in the mechanical cleaning process. From US Pat. No. 4,116,851 pasty thixotropic, strongly alkaline pot cleaning agents are known, which contain various thickeners and active chlorine compounds, the agents being applied to the material to be cleaned and coated with water over a longer period of time due to their gel structure Contact point remain and therefore have a particularly sustainable effect. However, it was not apparent from this patent that agents as described in the preceding invention would be suitable as pretreatment or cleaning agents for use in dishwashers.
Aus der US- Patentschrift 3 882 038 sind Reinigungsmittel für harte Oberflächen wie Kacheln, Fenster, Herde und dergleichen bekannt, die im wesentlichen aus Monobutyl- oder Monoamylethern von Propylenglykol, Dipropylenglykol oder Tripropylenglykol, einem nichtionischen Tensid und Wasser bestehen. Sie können auch Hydrotrope und Verdickungsmittel enthalten und auf verschiedene pH-Werte eingestellt sein. Die Verwendung als Vorbehandlungs- oder Einweichmittel von hartnäckigen Geschirranschmutzungen vor dem maschinellen Reinigungsprozeß wird nicht nahegelegt.US Pat. No. 3,882,038 discloses cleaning agents for hard surfaces such as tiles, windows, stoves and the like, which consist essentially of monobutyl or monoamyl ethers of propylene glycol, dipropylene glycol or tripropylene glycol, a nonionic surfactant and water. They can also contain hydrotropes and thickeners and can be adjusted to different pH values. The use as a pretreatment or soaking agent for stubborn stains on dishes before the machine cleaning process is not recommended.
Die kanadische Patentschrift 1 031 229 betrifft gelförmige maschinell anwendbare Geschirreinigungsmittel üblicher Zusammensetzung, deren Dosierung in die Geschirrspülmaschine leichter sein soll als die Dosierung entsprechender pulverförmiger Reinigungsmittel. Die Verwendung des Gels als Vorbehandlungs- und Einweichmittel für Geschirr wird nicht in Betracht gezogen.Canadian Patent 1,031,229 relates to gel-shaped, machine-applicable dishwashing detergents of conventional composition, the dosage of which in the dishwasher should be easier than the dosage of corresponding powdered detergents. The use of the gel as a pretreatment and soaking agent for dishes is not considered.
Die europäische Patentanmeldung 0 017 149 betrifft Allzweckreinigungsmittel für Haushalt und Gewerbebetriebe, bei denen die Reinigungswirkung nichtionischer Tenside durch den Zusatz von organischen Polymeren synergistisch gesteigert wird. Auch hier liegt die Anwendung der Mittel von der der vorliegenden Erfindung fern.European patent application 0 017 149 relates to general-purpose cleaning agents for household and commercial companies in which the cleaning action of nonionic surfactants is synergistically increased by the addition of organic polymers. Here too, the use of the agents is far from that of the present invention.
Die Einwirkzeit des gewünschten Mittels sollte einerseits möglichst kurz gehalten werden, um Arbeitsabläufe nicht zu verzögern, andererseits sollte aber auch nach Behandlung mit diesem Mittel selbst bei längeren Standzeiten des Spülgutes während des Sammelns in der Geschirrspülmaschine, ein erneutes Eintrocknen der Speisereste zusammen mit dem Mittel verhindert werden. Der Einsatz des erfindungsgemäß verwendeten Mittels sollte in der Weise erfolgen, daß der Anwender die schwierig zu entfernenden Speisereste, z.B. in einem Kochtopf oder in einer Bratpfanne, mit dem Mittel, etwa durch Sprühpumpen, Pinsel, Schaumpistolen, Spraydosen, in Kontakt bringt, dann das Spülgut sofort in zweckmäßiger Position in die Spülmaschine stellt, d.h. mit der Topföffnung nach unten in die Richtung des Wassersprühstrahles, wobei das viskose Produkt im wesentlichen auf der Topfoberfläche haften bleibt, und nach Bedarf den Reinigungsprozeß startet. Ein Ausspülen des Vorbehandlungs- oder Einweichmittels vor dem Reinigungsprozeß sollte nicht erforderlich sein.The exposure time of the desired agent should on the one hand be kept as short as possible so as not to delay work processes, but on the other hand even after treatment with this agent, even if the items to be washed have been in the dishwasher for a longer period of time, they should be prevented from drying out again with the agent will. The agent used according to the invention should be used in such a way that the user brings the food residues, which are difficult to remove, for example in a saucepan or in a frying pan, into contact with the agent, for example by means of spray pumps, brushes, foam guns, spray cans, then that Immediately place items to be washed in a suitable position in the dishwasher, ie with the pot opening downwards in the direction of the water spray, the viscous product essentially adhering to the pot surface and starting the cleaning process as required. It should not be necessary to rinse out the pretreatment or soaking agent before the cleaning process.
Die Erfindung betrifft daher die Verwendung von Mitteln, die aus
0,5 - 20, vorzugsweise 1 - 15 Gew.-% nichtionischen, insbesondere schwachschäumenden Tensiden,
0,5 - 25, vorzugsweise 1 - 20 Gew.-% mehrwertigen aliphatischen Alkoholen und/oder Glykolethern,
0,5 - 10, vorzugsweise 1 - 8 Gew. % einer hydrotropen Verbindung,
0,01 - 6, vorzugsweise 0,05 - 5 Gew.-% Viskositätsregulatoren und gegebenenfalls Duft- und Farbstoffen, Konservierungsmittel sowie geringste Mengen saurer oder alkalischer Mittel zur Einstellung des pH-Wertes in wäßriger Lösung oder Suspension bestehen und auf eine Viskosität von mindestens 5, vorzugsweise mindestens 20 mPas sowie auf einen pH-Wert von 2 - 7, vorzugsweise 3 - 6 eingestellt sind, zum Vorbehandeln oder Einweichen von hartnäckig angeschmutztem Geschirr für den maschinellen Reinigungsprozeß.The invention therefore relates to the use of agents which

0.5 - 25, preferably 1 - 20% by weight of polyhydric aliphatic alcohols and / or glycol ethers,
0.5-10, preferably 1-8% by weight of a hydrotropic compound,
0.01 - 6, preferably 0.05 - 5 wt .-% viscosity regulators and optionally fragrances and dyes, preservatives and very small amounts of acidic or alkaline agents for adjusting the pH in aqueous solution or suspension and to a viscosity of at least 5, preferably at least 20 mPas and a pH of 2-7, preferably 3-6, for pretreating or soaking stubbornly soiled dishes for the machine cleaning process.
Zu den geeigneten nichtionischen, vorzugsweise schwachschäumenden Tensiden gehören die Ethylenoxidaddukte an höhermolekulare Propylenglykole der Molgewichte 900 bis 4000 sowie Addukte von 1 bis 10 Mol Ethylenoxid, beziehungsweise 1 bis 10 Mol Ethylenoxid und 1 bis 7 Mol Propylenoxid an höhermolekulare Fettalkohole mit 8 bis 22, vorzugsweise 10 bis 16 Kohlenstoffatomen im Molekül oder deren natürlich vorkommende Gemische sowie synthetische, beispielsweise durch Oxosynthese hergestellte Alkohole der Kettenlänge C₁₂-C₁₈ und entsprechende Alkylenoxidaddukte an Nonylphenole in Betracht. Bevorzugt eingesetzt werden die biologisch weitestgehend abbaubaren Addukte von Ethylenoxid und Propylenoxid an höhermolekulare Fettalkohole, insbesondere das Anlagerungsprodukt von 2 bis 5 Mol Ethylenoxid und 2 bis 5 Mol Propylenoxid an ein Gemisch von C₁₂-C₁₈-Fettalkoholen. Die endständigen Hydroxygruppen der Addukte können auch durch Umsetzung von einem Mol eines Aldehyds oder Ketons mit jeweils zwei Mol eines Addukts in Acetale oder Ketale umgewandelt, "endgruppenverschlossen", werden. Auch ethoxilierte Diole mit bis zu 18 Kohlenstoffatomen und endständigen oder innenständigen vicinalen Hydroxylgruppen sowie die entsprechenden Monoglycoletherdiole kommen in Betracht.Suitable nonionic, preferably low-foaming surfactants include the ethylene oxide adducts with higher molecular weight propylene glycols with a molecular weight of 900 to 4000 and adducts with 1 to 10 moles of ethylene oxide or 1 to 10 moles of ethylene oxide and 1 to 7 moles of propylene oxide with higher molecular weight fatty alcohols with 8 to 22, preferably 10 up to 16 carbon atoms in the molecule or their naturally occurring mixtures and synthetic alcohols, for example those prepared by oxosynthesis, of chain length C₁₂-C₁₈ and corresponding alkylene oxide adducts with nonylphenols. Preference is given to using the largely biodegradable adducts of ethylene oxide and propylene oxide with higher molecular weight fatty alcohols, in particular the adduct of 2 to 5 moles of ethylene oxide and 2 to 5 moles of propylene oxide with a mixture of C₁₂-C₁₈ fatty alcohols.

Die im folgenden aufgeführten Untersuchungsergebnisse zeigen die Vorteile der erfindungsgemäß verwendeten Vorbehandlungs- oder Einweichmittel.The test results listed below show the advantages of the pretreatment or soaking agents used according to the invention.
Es wurden mit der Haushalts-Geschirrspülmaschine vom Typ Miele G 520 gearbeitet. Die Reinigung der Töpfe mit den später beschriebenen Testanschmutzungen erfolgte im Reinigungsgang bei 55 °C und zwecks besserer Vergleichbarkeit ohne nachfolgende Klarspüleranwendung. Pro Reinigungsgang wurden 4 Töpfe - Öffnung gegen den Sprühstrahl, hier nach unten - in den unteren Geschirrkorb der Spülmaschine gestellt.The household dishwasher type Miele G 520 was used. The pots with the test soils described later were cleaned in the cleaning cycle at 55 ° C and for the purpose of better comparability without subsequent rinse aid application. For each cleaning cycle, 4 pots - opening against the spray jet, down here - were placed in the lower dishwasher basket.
Die Wirkung des erfindungsgemäß verwendeten Vorbehandlungs- oder Einweichmittels wurde mit der Reinigungsleistung verglichen, die sich bei der Anwendung von 30 g eines üblichen Standardreinigungsmittels allein ergibt, bestehend aus:
40 Gew.-% Pentannatriumtriphosphat, wasserfrei
45 Gew.-% Natriummetasilikat, wasserfrei
5 Gew.-% Natriumcarbonat, wasserfrei
1 Gew.-% Trichlorisocyanursäure
1 Gew.-% eines Adduktes von 5 Mol Ethylenoxid (E0) und 4 Mol Propylenoxid (P0) an einen C₁₂-C₁₄-Fettalkohol
Rest Wasser.The effect of the pretreatment or soaking agent used according to the invention was compared with the cleaning performance which results when using 30 g of a standard cleaning agent alone, consisting of:
40% by weight pentasodium triphosphate, anhydrous
45% by weight sodium metasilicate, anhydrous
5% by weight sodium carbonate, anhydrous
