Description

Die vorliegende Erfindung betrifft eine bleichverstärkende Wirkstoffkombination, die ein Übergangsmetallsalz, ein Ammoniumsalz und ein Oxidationsmittel enthält, ein Verfahren zur Herstellung einer solchen Wirkstoffkombination, die Verwendung einer derartigen Wirkstoffkombination zur Verstärkung der Bleichwirkung von insbesondere anorganischen Persauerstoffverbindungen, insbesondere beim Bleichen von gefärbten Anschmutzungen an harten Oberflächen, und Reinigungsmittel für harte Oberflächen, die eine derartige Wirkstoffkombination enthalten.The present invention relates to a bleach-enhancing active ingredient combination, the one Transition metal salt, an ammonium salt and an oxidizing agent contains a method to produce such a combination of active ingredients, the use of such Active ingredient combination for enhancing the bleaching effect of, in particular, inorganic Peroxygen compounds, especially when bleaching colored ones Soiling on hard surfaces, and detergents for hard surfaces contain such an active ingredient combination.

Anorganische Persauerstoffverbindungen, insbesondere Wasserstoffperoxid und feste Persauerstoffverbindungen, die sich in Wasser unter Freisetzung von Wasserstoffperoxid lösen, wie Natriumperborat und Natriumcarbonat-Perhydrat, werden seit langem als Oxidationsmittel zu Desinfektions- und Bleichzwecken verwendet. Die Oxidationswirkung dieser Substanzen hängt in verdünnten Lösungen stark von der Temperatur ab; so erzielt man beispielsweise mit H2O2 oder Perborat in alkalischen Bleichflotten erst bei Temperaturen oberhalb von etwa 80 °C eine ausreichend schnelle Bleiche verschmutzter Textilien. Bei niedrigeren Temperaturen kann die Oxidationswirkung der anorganischen Persauerstoffverbindungen durch Zusatz sogenannter Bleichaktivatoren verbessert werden, für die zahlreiche Vorschläge, vor allem aus den Stoffklassen der N- oder O-Acylverbindungen, beispielsweise mehrfach acylierte Alkylendiamine, insbesondere Tetraacetylethylendiamin, acylierte Glykolurile, insbesondere Tetraacetylglykoluril, N-acylierte Hydantoine, Hydrazide, Triazole, Hydrotriazine, Urazole, Diketopiperazine, Sulfurylamide und Cyanurate, außerdem Carbonsäureanhydride, insbesondere Phthalsäureanhydrid, Carbonsäureester, insbesondere Natrium-nonanoyloxy-benzolsulfonat, Natrium-isononanoyloxybenzolsulfonat und acylierte Zuckerderivate, wie Pentaacetylglukose, in der Literatur bekannt geworden sind. Durch Zusatz dieser Substanzen kann die Bleichwirkung wäßriger Peroxidflotten so weit gesteigert werden, daß bereits bei Temperaturen um 60 °C im wesentlichen die gleichen Wirkungen wie mit der Peroxidflotte allein bei 95 °C eintreten. Inorganic peroxygen compounds, especially hydrogen peroxide and solid peroxygen compounds, which dissolve in water to release hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfection and bleaching purposes. The oxidizing effect of these substances in dilute solutions depends strongly on the temperature; For example, with H 2 O 2 or perborate in alkaline bleaching liquors, sufficiently quick bleaching of soiled textiles can only be achieved at temperatures above about 80 ° C. At lower temperatures, the oxidation effect of the inorganic peroxygen compounds can be improved by the addition of so-called bleach activators, for which numerous suggestions, especially from the substance classes of the N- or O-acyl compounds, for example multiply acylated alkylenediamines, in particular tetraacetylethylenediamine, acylated glycolurils, in particular tetraacetylglycoluril, N- acylated hydantoins, hydrazides, triazoles, Hydrotriazine, urazoles, diketopiperazines, sulfuryl amides and cyanurates, also carboxylic anhydrides, especially phthalic anhydride, Carbonsäureester, especially sodium nonanoyloxybenzenesulfonate, sodium isononanoyloxybenzenesulfonate and acylated sugar derivatives, such as pentaacetylglucose, are known in the literature. By adding these substances, the bleaching effect of aqueous peroxide liquors can be increased to such an extent that, even at temperatures around 60 ° C., essentially the same effects occur as with the peroxide liquor alone at 95 ° C.

Im Bemühen um energiesparende Wasch- und Bleichverfahren gewinnen in den letzten Jahren Anwendungstemperaturen deutlich unterhalb 60 °C, insbesondere unterhalb 45 °C bis herunter zur Kaltwassertemperatur an Bedeutung.In the effort to save energy in washing and bleaching have won in recent years Years of application temperatures well below 60 ° C, especially below 45 ° C down to the cold water temperature in importance.

Bei diesen niedrigen Temperaturen läßt die Wirkung der bisher bekannten Aktivatorverbindungen in der Regel erkennbar nach. Es hat deshalb nicht an Bestrebungen gefehlt, für diesen Temperaturbereich wirksamere Aktivatoren zu entwickeln, ohne daß bis heute ein überzeugender Erfolg zu verzeichnen gewesen wäre. Ein Ansatzpunkt dazu ergibt sich durch den Einsatz von Übergangsmetallsalzen und -komplexen, wie zum Beispiel in den europäischen Patentanmeldungen EP 392 592, EP 443 651, EP 458 397, EP 544 490 oder EP 549 271 vorgeschlagen, als sogenannte Bleichkatalysatoren. Bei diesen besteht, vermutlich wegen der hohen Reaktivität der aus ihnen und der Persauerstoffverbindung entstehenden oxidierenden Intermediate, die Gefahr der Farbveränderung gefärbter Textilien und im Extremfall der oxidativen Textilschädigung. In der europäischen Patentanmeldung EP 272 030 werden Cobalt(III)-Komplexe mit Ammoniak-Liganden, die außerdem beliebige weitere ein-, zwei-, drei- und/oder vierzähnige Liganden aufweisen können, als Aktivatoren für H2O2 zum Einsatz in Textilwasch- oder -bleichmitteln beschrieben. Die internationalen Patentanmeldungen WO 96/23859, WO 96/23860 und WO 96/23861 betreffen den Einsatz entsprechender Co(III)-Komplexe in Mitteln zum automatischen Reinigen von Geschirr. Aus der europäischen Patentanmeldung EP 630 964 sind bestimmte Mangankomplexe bekannt, welche keinen ausgeprägten Effekt hinsichtlich einer Bleichverstärkung von Persauerstoffverbindungen haben und gefärbte Textilfasern nicht entfärben, aber die Bleiche von in Waschlaugen befindlichem, von der Faser abgelöstem Schmutz oder Farbstoff bewirken können. Aus der deutschen Patentanmeldung DE 44 16 438 sind Mangan-, Kupfer- und Cobalt-Komplexe bekannt, welche Liganden aus einer Vielzahl von Stoffgruppen tragen können und als Bleich- und Oxidationskatalysatoren verwendet werden sollen.At these low temperatures, the effect of the activator compounds known to date generally diminishes appreciably. There has been no shortage of efforts to develop more effective activators for this temperature range without convincing success to date. One starting point for this is the use of transition metal salts and complexes, as proposed, for example, in European patent applications EP 392 592, EP 443 651, EP 458 397, EP 544 490 or EP 549 271, as so-called bleaching catalysts. With these, presumably because of the high reactivity of the oxidizing intermediates formed from them and the peroxygen compound, there is a risk of changing the color of colored textiles and, in extreme cases, of oxidative textile damage. In European patent application EP 272 030, cobalt (III) complexes with ammonia ligands, which can also have any further one, two, three and / or tidentate ligands, are used as activators for H 2 O 2 for use in textile washing - or bleaches described. International patent applications WO 96/23859, WO 96/23860 and WO 96/23861 relate to the use of corresponding Co (III) complexes in agents for automatically cleaning dishes. From European patent application EP 630 964, certain manganese complexes are known which have no pronounced effect with regard to a bleaching enhancement of peroxygen compounds and which do not discolor dyed textile fibers, but which can cause bleaching of dirt or dye which is detached from the fiber and which is detached from the fiber. German patent application DE 44 16 438 discloses manganese, copper and cobalt complexes which can carry ligands from a large number of groups of substances and are to be used as bleaching and oxidation catalysts.

Die vorliegende Erfindung hat die Verbesserung der Oxidations- und Bleichwirkung anorganischer Persauerstoffverbindungen bei niedrigen Temperaturen unterhalb von 80 °C, insbesondere im Temperaturbereich von ca. 15 °C bis 45 °C, zum Ziel. The present invention has the improvement of the oxidation and bleaching effect of inorganic Peroxygen compounds at low temperatures below 80 ° C, especially in the temperature range of approx. 15 ° C to 45 ° C.

Es wurde nun gefunden, daß bestimmte Übergangsmetallsalze, die als solche im wesentlichen keinen Beitrag zum Erreichen dieses Ziels liefern, eine deutliche bleichkatalysierende Wirkung auf gefärbte Anschmutzungen haben, die sich an harten Oberflächen befinden, wenn man die Übergangsmetallsalze in Form einer Wirkstoffkombination, die zusätzlich ein Ammoniumsalz und gegebenenfalls ein Oxidationsmittel enthält, einsetzt.It has now been found that certain transition metal salts, which as such in make a significant contribution to achieving this goal, a significant bleach-catalyzing They have an effect on colored soiling, which can be found on hard surfaces if you have the transition metal salts in the form of an active ingredient combination, the additionally contains an ammonium salt and optionally an oxidizing agent.

Gegenstand der Erfindung ist eine in inniger Abmischung der Bestandteile vorliegende, insbesondere in Teilchenform konfektionierte bleichverstärkende Wirkstoffkombination gemäß des anhängenden Anspruchs 1, die durch inniges Abmischen eines wasserlöslichen Salzes eines zweiwertigen Übergangsmetalles, ausgewählt aus Cobalt, Eisen, Kupfer und Ruthenium, eines wasserlöslichen Ammoniumsalzes, wozu insbesondere Ammoniumhalogenid, -sulfat,-carbonat, -hydrogencarbonat, -phosphat, -phosphonat, -nitrat, -perchlorat und/oder -citrat gehören, und gegebenenfalls eines Oxidationsmittels auf Persauerstoffbasis sowie inertem, das heißt mit eventuell vorhandenem Oxidationsmittel nicht reagierendem Trägermaterial, wozu insbesondere Alkalisulfat, Alkalicarbonat, Alkalichlorid, Alkalisilikat und deren Gemische gehören, erhältlich ist.The object of the invention is an intimate mixture of the components, in particular in bleach-strengthening active ingredient combination made up in particle form according to appended claim 1, by intimately mixing a water-soluble salt of a divalent Transition metal, selected from cobalt, iron, copper and ruthenium, one water-soluble ammonium salt, in particular ammonium halide, sulfate, carbonate, -hydrogen carbonate, -phosphate, -phosphonate, -nitrate, -perchlorate and / or -citrate belong, and optionally an oxidizing agent based on peroxygen as well inert, that is to say which does not react with any oxidizing agent present Carrier material, in particular alkali sulfate, alkali carbonate, alkali chloride, alkali silicate and their mixtures belong.

Unter wasserlöslich" sollen hier Salze verstanden werden, die sich bei Raumtemperatur zu mindestens 4 g/l, insbesondere mindestens 10 g/l in destilliertem Wasser lösen.Water-soluble "should be understood here to mean salts which are at room temperature Dissolve at least 4 g / l, especially at least 10 g / l in distilled water.

In der Wirkstoffkombination sind vorzugsweise 0,01 Gew.-% bis 1 Gew.-%, insbesondere 0,1 Gew.-% bis 0,5 Gew.-%, Übergangsmetall aus dem Übergangsmetallsalz enthalten. Der Gehalt an Ammoniumsalz beträgt vorzugsweise 1 Gew.-% bis 10 Gew.-%. Der Rest auf 100 Gew.-% kann aus inertem Trägermaterial bestehen. Vorzugsweise sind jedoch in der erfindungsgemäßen Wirkstoffkombination 1 Gew.-% bis 20 Gew.-%, insbesondere 2 Gew.-% bis 10 Gew.-% Oxidationsmittel auf Persauerstoffbasis enthalten.The active ingredient combination preferably contains 0.01% by weight to 1% by weight, in particular 0.1 wt .-% to 0.5 wt .-%, transition metal from the transition metal salt. The ammonium salt content is preferably 1 wt% to 10 wt%. The rest to 100 wt .-% can be made of inert Carrier material exist. However, are preferred in the invention Active ingredient combination 1% by weight to 20% by weight, in particular 2% by weight to 10% by weight Peroxygen based oxidizers.

Ein weiterer Gegenstand der Erfindung ist die Verwendung einer solchen Wirkstoffkombination als Aktivator für insbesondere anorganische Persauerstoffverbindungen in wäßrigen Reinigungslösungen für harte Oberflächen, insbesondere für Geschirr. Dabei muß überraschen, daß weder bei Lagerung der erfindungsgemäßen Wirkstoffkombination noch bei deren Anwendung in wäßrigen Reinigungsflotten ein bekanntlich bleichaktivierende Wirkung aufweisender Übergangsmetall-Amminkomplex vom Typ des [Co(NH3)6- xClx]Cl3-x mit x = 0 bis 3 nachweisbar ist, obwohl die bleichaktivierende Wirkung der erfindungsgemäßen Wirkstoffkombination mindestens genauso hoch ist wie diejenige solcher Katalysatorkomplexe.Another object of the invention is the use of such a combination of active ingredients as an activator for, in particular, inorganic peroxygen compounds in aqueous cleaning solutions for hard surfaces, in particular for dishes. It must be surprising that neither when the active substance combination according to the invention is stored nor when used in aqueous cleaning liquors does a transition metal-amine complex of the type known as [Co (NH 3 ) 6- x Cl x ] Cl 3-x with x = 0 to have a bleach-activating effect 3 is detectable, although the bleach-activating effect of the active compound combination according to the invention is at least as high as that of such catalyst complexes.

Zu den bevorzugten zweiwertigen Übergangsmetallsalzen gehören Cobalt(II)-chlorid, das in wasserfreier Form oder als Hexahydrat eingesetzt werden kann, Cobalt(II)-sulfat, Cobalt(II)-carbonat und Cobalt(II)-acetat, allein oder in Abmischungen.The preferred divalent transition metal salts include cobalt (II) chloride, the can be used in anhydrous form or as hexahydrate, cobalt (II) sulfate, cobalt (II) carbonate and cobalt (II) acetate, alone or in admixtures.

Das Übergangsmetall wird erfindungsgemäß in Form der obengenannten Wirkstoffkombination eingesetzt. Diese kann in ihrer einfachsten Form eine durch Mischen in üblichen Mischern erhältliche Abmischung des zweiwertigen Übergangsmetallsalzes mit den weiteren Komponenten der Wirkstoffkombination sein. Dazu vermischt man 1 Gew.-Teil des zweiwertigen Übergangsmetallsalzes mit 0,5 Gew.-Teilen bis 10 Gew.-Teilen, insbesondere 2 Gew.-Teilen bis 7,5 Gew.-Teilen Ammoniumsalz, bis zu 20 Gew.-Teilen, insbesondere 2 Gew.-Teilen bis 10 Gew.-Teilen Oxidationsmittel auf Persauerstoffbasis und 50 Gew.-Teilen bis 150 Gew.-Teilen, insbesondere 70 Gew.-Teilen bis 100 Gew.-Teilen inertem Trägermaterial. Man kann die dazu bevorzugt pulverförmig vorliegenden Komponenten der Wirkstoffkombination auch einer Aufbaugranulation, gegebenenfalls unter Einsatz üblicher Granulationshilfsmittel wie wäßrigen Alkalisilikat-Lösungen oder Lösungen von Salzen polymerer Polycarboxylate, unterwerfen, um die Handhabbarkeit der Wirkstoffkombination zu erleichtern. Bevorzugt schließt sich an das Vermischen der Bestandteile, das im wesentlichen bei Raumtemperatur beziehungsweise bei der sich durch den Energieeintrag des Mischers ergebenden Temperatur durchgeführt wird, eine thermische Nachbehandlung der Wirkstoffkombination über einen Zeitraum von beispielsweise bis zu 120 Minuten, insbesondere 15 Minuten bis 60 Minuten, an. Bei diesem Verfahrensteilschritt ist das Erwärmen auf Temperaturen im Bereich von 40 °C bis 90 °C, insbesondere 60 °C bis 80 °C normalerweise völlig ausreichend. Dabei nimmt der Stickstoffgehalt (aus dem Ammoniumsalz), der bezogen auf das Übergangsmetall vor dem Tempern vorzugsweise im Atomverhältnis-Bereich von etwa 6:1 bis etwa 4:1 liegt, ab und liegt nach dem Tempern im Atomverhältnis-Bereich von etwa 2:1 bis unter 3:1.According to the invention, the transition metal is in the form of the active ingredient combination mentioned above used. In its simplest form, this can be done by mixing in the usual way Mixers available mixing of the divalent transition metal salt with the be further components of the active ingredient combination. To do this, mix 1 part by weight of the divalent transition metal salt with 0.5 part by weight to 10 parts by weight, in particular 2 parts by weight to 7.5 parts by weight of ammonium salt, up to 20 parts by weight, in particular 2 parts by weight to 10 parts by weight of oxidizing agent Peroxygen base and 50 parts by weight to 150 parts by weight, especially 70 parts by weight up to 100 parts by weight of inert carrier material. They can be preferred components of the combination of active ingredients also in powder form, including a build-up granulation, optionally using conventional granulation aids such as aqueous ones Alkali silicate solutions or solutions of salts of polymeric polycarboxylates, subject to facilitate the handling of the active ingredient combination. Prefers joins the mixing of the ingredients, which essentially Room temperature or at which the energy input of the mixer resulting temperature is carried out, a thermal aftertreatment of the active ingredient combination over a period of up to 120 minutes, for example, especially 15 minutes to 60 minutes. In this sub-step this is Heating to temperatures in the range of 40 ° C to 90 ° C, especially 60 ° C to 80 ° C is normally sufficient. The nitrogen content (from the Ammonium salt), which is preferred based on the transition metal before the annealing is in the atomic ratio range from about 6: 1 to about 4: 1, and is after Annealing in the atomic ratio range from about 2: 1 to less than 3: 1.

Ohne durch diese Theorie gebunden sein zu wollen, bilden sich bei diesem Vorgehen vermutlich polynukleare Übergangsmetallkomplexe, bei denen eventuell Ammoniak, die Anionen des Ammoniumsalzes sowie die Anionen der Trägermaterialsalze die Rolle der Liganden übernehmen. Bei Einsatz von Co(II)-salzen entstehen vermutlich, insbesondere bei gleichzeitiger Anwesenheit von peroxidischem Oxidationsmittel, bekanntlich wesentlich stabilere Co(III)-Komplexe, die in polymerer Form als mehrkernige Komplexe, möglicherweise vom Typ des nachstehend beispielhaft wiedergegebenen flächenverknüpften dreikernigen Komplexes

Figure 00050001
vorliegen, wobei auch der Ersatz zumindest einzelner verbrückender µ-OH-Gruppen durch verbrückende µ-Imino- oder µ-Aminogruppen und die weitere Verknüpfung zu noch höherkernigen Komplexen denkbar ist. Eine derartige Bildung polynuklearer Komplexe findet vermutlich auch beim innigen Abmischen der Bestandteile ohne nachfolgende Temperung oder bei der Anwendung der nicht getemperten Wirkstoffkombination im wäßrigen System statt.Without wishing to be bound by this theory, this procedure presumably forms polynuclear transition metal complexes in which ammonia, the anions of the ammonium salt and the anions of the carrier material salts may assume the role of the ligands. When Co (II) salts are used, it is known that, particularly in the presence of peroxidic oxidizing agents, there are known to be significantly more stable Co (III) complexes, which in polymer form are known as multinuclear complexes, possibly of the type of the face-sharing trinuclear complex exemplified below
Figure 00050001
are present, the replacement of at least individual bridging μ-OH groups by bridging μ-imino or μ-amino groups and the further linkage to even higher-nucleus complexes is also conceivable. Such formation of polynuclear complexes presumably also takes place when the constituents are mixed intimately without subsequent tempering or when the non-tempered combination of active ingredients is used in the aqueous system.

Eine erfindungsgemäße bleichverstärkende Wirkstoffkombination wird vorzugsweise in Reinigungslösungen für harte Oberflächen, insbesondere für Geschirr, zum Bleichen von gefärbten Anschmutzungen verwendet. Dabei wird unter dem Begriff der Bleiche sowohl das Bleichen von sich auf der harten Oberfläche befindendem Schmutz, insbesondere Tee, als auch das Bleichen von in der Geschirrspülflotte befindlichem, von der harten Oberfläche abgelöstem Schmutz verstanden. A bleach-enhancing active ingredient combination according to the invention is preferably used in Cleaning solutions for hard surfaces, especially for dishes, for bleaching colored stains used. Here, the term bleaching is used both the bleaching of dirt on the hard surface, especially tea, as well as the bleaching of those in the dishwashing liquor, from the hard ones Understood dirt removed.

Weiterhin betrifft die Erfindung Reinigungsmittel für harte Oberflächen, insbesondere Reinigungsmittel für Geschirr und unter diesen vorzugsweise solche für den Einsatz in maschinellen Reinigungsverfahren, die eine oben beschriebene Wirkstoffkombination enthalten, und ein Verfahren zur Reinigung von harten Oberflächen, insbesondere von Geschirr unter Einsatz einer derartigen Wirkstoffkombination in wäßriger, gegebenenfalls weitere Reinigungsmittelbestandteile enthaltender Lösung.The invention further relates to cleaning agents for hard surfaces, in particular Detergents for dishes and preferably those for use in mechanical cleaning processes which contain an active ingredient combination described above, and a method for cleaning hard surfaces, in particular of Dishes using such a combination of active ingredients in aqueous, if appropriate solution containing further detergent components.

Die erfindungsgemäße Verwendung besteht im wesentlichen darin, in Gegenwart einer mit gefärbten Anschmutzungen verunreinigten harten Oberfläche Bedingungen zu schaffen, unter denen ein peroxidisches Oxidationsmittel und die bleichverstärkende Wirkstoffkombination miteinander reagieren können, mit dem Ziel, stärker oxidierend wirkende Folgeprodukte zu erhalten. Solche Bedingungen liegen insbesondere dann vor, wenn beide Reaktionspartner in wäßriger Lösung aufeinander treffen. Dies kann durch separate Zugabe der Persauerstoffverbindung und der Wirkstoffkombination zu einer gegebenenfalls reinigungsmittelhaltigen Lösung geschehen. Besonders vorteilhaft wird das erfindungsgemäße Verfahren jedoch unter Verwendung eines erfindungsgemäßen Reinigungsmittels für harte Oberflächen, das die Wirkstoffkombination und gegebenenfalls ein persauerstoffhaltiges Oxidationsmittel enthält, durchgeführt. Falls das Reinigungsmittel keine sonstige persauerstoffhaltige Oxidationsmittelkomponente enthält, ist es bevorzugt, daß die erfindungsgemäße Wirkstoffkombination ein Oxidationsmittel auf Persauerstoffbasis enthält. Die Persauerstoffverbindung kann auch separat, in Substanz oder als vorzugsweise wäßrige Lösung oder Suspension, zur Lösung zugegeben werden, wenn ein peroxidfreies Reinigungsmittel verwendet wird.The use according to the invention consists essentially in the presence of a hard surface contaminated with colored stains create, among which a peroxidic oxidizing agent and the bleaching enhancer Active ingredient combinations can react with each other, with the aim of being more oxidizing to obtain effective secondary products. Such conditions exist in particular when both reactants meet in aqueous solution. This can be done by separate addition of the peroxygen compound and the active ingredient combination to one if necessary, detergent-containing solution. Is particularly advantageous the inventive method, however, using an inventive Cleaning agent for hard surfaces, the combination of active ingredients and, if necessary contains an oxidizing agent containing peroxy. If that Cleaning agent does not contain any other oxidant components containing peroxygen, it is preferred that the active ingredient combination according to the invention is an oxidizing agent based on peroxygen. The peroxygen compound can also be separately, in substance or as a preferably aqueous solution or suspension, added to the solution if a peroxide-free cleaning agent is used.

Je nach Verwendungszweck können die Bedingungen weit variiert werden. So kommen neben rein wäßrigen Lösungen auch Mischungen aus Wasser und geeigneten organischen Lösungsmitteln als Reaktionsmedium in Frage. Die Einsatzmengen an Persauerstoffverbindungen werden im allgemeinen so gewählt, daß in den Lösungen zwischen 10 ppm und 10 % Aktivsauerstoff, vorzugsweise zwischen 50 ppm und 5 000 ppm Aktivsauerstoff vorhanden sind. Auch die verwendete Menge an bleichverstärkender Wirkstoffkombination hängt vom Anwendungszweck ab. Je nach gewünschtem Aktivierungsgrad wird die Wirkstoffkombination in solchen Mengen eingesetzt, daß 0,00001 Mol bis 0,025 Mol, vorzugsweise 0,0001 Mol bis 0,02 Mol Übergangsmetall pro Mol Persauerstoffverbindung verwendet werden, doch können in besonderen Fällen diese Grenzen auch über- oder unterschritten werden.The conditions can be varied widely depending on the intended use. So come in addition to purely aqueous solutions, also mixtures of water and suitable organic Solvents as a reaction medium in question. The quantities of peroxygen compounds used are generally chosen so that in the solutions between 10 ppm and 10% active oxygen, preferably between 50 ppm and 5,000 ppm Active oxygen is present. Also the amount of bleach enhancer used The combination of active ingredients depends on the intended use. Depending on the desired level of activation the combination of active ingredients is used in such amounts that 0.00001 mol to 0.025 mol, preferably 0.0001 mol to 0.02 mol, of transition metal per Moles of peroxygen compound can be used, but in special cases this can Limits can also be exceeded or undershot.

Ein weiterer Gegenstand der Erfindung ist ein Reinigungsmittel für harte Oberflächen, insbesondere für Geschirr, welches 0,25 Gew.-% bis 25 Gew.-%, insbesondere 1 Gew.-% bis 10 Gew.-% einer bleichverstärkenden Wirkstoffkombination neben üblichen, mit der Wirkstoffkombination verträglichen Inhaltsstoffen enthält.Another object of the invention is a cleaning agent for hard surfaces, in particular for dishes which contain 0.25% by weight to 25% by weight, in particular 1% by weight up to 10 wt .-% of a bleach-enhancing active ingredient combination in addition to the usual, with the Active ingredient combination contains compatible ingredients.

Die erfindungsgemäßen Reinigungsmittel, die als pulver- oder tablettenförmige Feststoffe, homogene Lösungen oder Suspensionen vorliegen können, können außer der erfindungsgemäß verwendeten Wirkstoffkombination im Prinzip alle bekannten und in derartigen Mitteln üblichen Inhaltsstoffe enthalten. Die erfindungsgemäßen Mittel können insbesondere Buildersubstanzen, oberflächenaktive Tenside, Persauerstoffverbindungen, wassermischbare organische Lösungsmittel, Enzyme, Sequestrierungsmittel, Elektrolyte, pH-Regulatoren und weitere Hilfsstoffe, wie Silberkorrosionsinhibitoren, Schaumregulatoren, zusätzliche Persauerstoff-Aktivatoren sowie Farb- und Duftstoffe enthalten.The cleaning agents according to the invention, which are in powder or tablet form Solids, homogeneous solutions or suspensions can also exist In principle, active ingredient combination used according to the invention are all known and in Such agents contain common ingredients.

Abrasivstoffe sind in den erfindungsgemäßen Reinigungsmitteln vorzugsweise nicht über 20 Gew.-%, insbesondere von 5 Gew.-% bis 15 Gew.-%, enthalten.A cleaning agent for hard surfaces according to the invention can also abrasive components, in particular from the group comprising quartz flours, Wood flours, plastic flours, chalks and micro glass balls and their mixtures, contain. Abrasives are preferred in the cleaning agents according to the invention do not contain more than 20% by weight, in particular from 5% by weight to 15% by weight.

Ein weiterer Erfindungsgegenstand ist ein Mittel zum maschinellen Reinigen von Geschirr, enthaltend 15 Gew.-% bis 60 Gew.-%, insbesondere 20 Gew.-% bis 50 Gew.-% wasserlösliche Builderkomponente, 5 Gew.-% bis 25 Gew.-%, insbesondere 8 Gew.-% bis 17 Gew.-% Bleichmittel auf Sauerstoffbasis, jeweils bezogen auf das gesamte Mittel, welches die bleichaktivierende Wirkstoffkombination, insbesondere in Mengen von 1 Gew.-% bis 10 Gew.-%, enthält, wobei die Angaben zur Bleichmittelmenge die eventuell in der Wirkstoffkombination enthaltene Menge an Oxidationsmittel einschließen. Ein derartiges Mittel ist insbesondere niederalkalisch, das heißt seine 1-gewichtsprozentige Lösung weist einen pH-Wert von 8 bis 11,5, vorzugsweise 9 bis 11 auf.Another object of the invention is a means for machine cleaning Tableware containing 15% by weight to 60% by weight, in particular 20% by weight to 50% by weight water-soluble builder component, 5% by weight to 25% by weight, in particular 8% by weight up to 17% by weight of bleaching agent based on oxygen, in each case based on the total agent, which the bleach-activating active ingredient combination, in particular in amounts of 1 wt .-% to 10 wt .-%, the information on the amount of bleach contains the any amount of oxidizing agent contained in the active ingredient combination lock in. Such an agent is particularly low alkaline, that is to say its 1% by weight Solution has a pH of 8 to 11.5, preferably 9 to 11.

Als wasserlösliche Builderkomponenten insbesondere in derartigen niederalkalischen Reinigungsmitteln kommen prinzipiell alle in Mitteln für die maschinelle Reinigung von Geschirr üblicherweise eingesetzten Builder in Frage, zum Beispiel polymere Alkaliphosphate, die in Form ihrer alkalischen neutralen oder sauren Natrium- oder Kaliumsalze vorliegen können. Beispiele hierfür sind Tetranatriumdiphosphat, Dinatriumdihydrogendiphosphat, Pentanatriumtriphosphat, sogenanntes Natriumhexametaphosphat sowie die entsprechenden Kaliumsalze beziehungsweise Gemische aus Natrium- und Kaliumsalzen. Ihre Mengen können im Bereich von bis zu etwa 60 Gew.-%, bezogen auf das gesamte Mittel liegen; es ist jedoch möglich, daß die erfindungsgemäßen Mittel frei von solchen Phosphaten sind. Weitere mögliche wasserlösliche Builderkomponenten sind zum Beispiel organische Polymere nativen oder synthetischen Ursprungs, vor allem Polycarboxylate, die insbesondere in Hartwasserregionen als Co-Builder wirken. In Betracht kommen beispielsweise Polyacrylsäuren und Copolymere aus Maleinsäureanhydrid und Acrylsäure sowie die Natriumsalze dieser Polymersäuren. Handelsübliche Produkte sind zum Beispiel Sokalan® CP 5 und PA 30 der Firma BASF. Zu den als Co-Builder brauchbaren Polymeren nativen Ursprungs gehören beispielsweise oxidierte Stärke, wie zum Beispiel aus der internationalen Patentanmeldung WO 94/05762 bekannt, und Polyaminosäuren wie Polyglutaminsäure oder Polyasparaginsäure. Weitere mögliche Builderkomponenten sind natürlich vorkommende Hydroxycarbonsäuren wie zum Beispiel Mono-, Dihydroxybernsteinsäure, α-Hydroxypropionsäure und Gluconsäure. Zu den bevorzugten Builderkomponenten gehören die Salze der Citronensäure, insbesondere Natriumcitrat. Als Natriumcitrat kommen wasserfreies Trinatriumcitrat und vorzugsweise Trinatriumcitratdihydrat in Betracht. Trinatriumcitratdihydrat kann als fein- oder grobkristallines Pulver eingesetzt werden. In Abhängigkeit vom letztlich in den erfindungsgemäßen Mitteln eingestellten pH-Wert können auch die zu den genannten Co-Builder-Salzen korrespondierenden Säuren vorliegen. As water-soluble builder components, especially in such low-alkaline cleaning agents In principle, all come in agents for the automatic cleaning of dishes usually used builders in question, for example polymeric Alkali phosphates, in the form of their alkaline neutral or acidic sodium or Potassium salts can be present. Examples include tetrasodium diphosphate, Disodium dihydrogen diphosphate, pentasodium triphosphate, so-called Sodium hexametaphosphate and the corresponding potassium salts respectively Mixtures of sodium and potassium salts. Their quantities can range up to about 60% by weight, based on the total agent; however, it is possible that the Agents according to the invention are free from such phosphates. Other possible water soluble For example, builder components are native or organic polymers of synthetic origin, especially polycarboxylates, particularly in hard water regions act as a co-builder. For example, polyacrylic acids and Copolymers of maleic anhydride and acrylic acid and the sodium salts thereof Polymer acids. Commercial products include Sokalan® CP 5 and PA 30 from the company BASF. Polymers of native origin that can be used as co-builders include for example oxidized starch, such as from the international patent application WO 94/05762 known, and polyamino acids such as polyglutamic acid or Polyaspartic acid. Other possible builder components are naturally occurring Hydroxycarboxylic acids such as mono-, dihydroxysuccinic acid, α-hydroxypropionic acid and gluconic acid. The preferred builder components include Salts of citric acid, especially sodium citrate. As sodium citrate come anhydrous Trisodium citrate and preferably trisodium citrate dihydrate. trisodium can be used as a fine or coarse crystalline powder. In Depending on the pH value ultimately set in the agents according to the invention the acids corresponding to the co-builder salts mentioned are also present.

Als Bleichmittel auf Sauerstoffbasis kommen in erster Linie Wasserstoffperoxid sowie Alkaliperboratmono- beziehungsweise -tetrahydrat und/oder Alkalipercarbonat in Betracht, wobei Natrium das bevorzugte Alkalimetall ist. Wasserstoffperoxid kann dabei auch mit Hilfe eines enzymatischen Systems, das heißt einer Oxidase und ihres Substrats, erzeugt werden. Der Einsatz von Natriumpercarbonat hat insbesondere in Reinigungsmitteln für Geschirr Vorteile, da es sich besonders günstig auf das Korrosionsverhalten an Gläsern auswirkt. Das Bleichmittel auf Sauerstoffbasis ist deshalb vorzugsweise ein Alkalipercarbonat, insbesondere Natriumpercarbonat. Zusätzlich oder insbesondere alternativ können auch bekannte Peroxycarbonsäuren, zum Beispiel Dodecandipersäure oder Phthalimidopercarbonsäuren, die gegebenenfalls am Aromaten substituiert sein können, enthalten sein. Überdies kann auch der Zusatz geringer Mengen bekannter Bleichmittelstabilisatoren wie beispielsweise von Phosphonaten, Boraten beziehungsweise Metaboraten und Metasilikaten sowie Magnesiumsalzen wie Magnesiumsulfat zweckdienlich sein.As an oxygen-based bleach come primarily hydrogen peroxide as well Alkali perborate or tetrahydrate and / or alkali percarbonate into consideration, with sodium being the preferred alkali metal. Hydrogen peroxide can also with the help of an enzymatic system, i.e. an oxidase and its substrate, be generated. The use of sodium percarbonate has in particular Dishwashing detergent benefits as it is particularly beneficial on the Corrosion behavior affects glasses. The oxygen-based bleach is therefore preferably an alkali percarbonate, especially sodium percarbonate. In addition or in particular alternatively, known peroxycarboxylic acids, for example Dodecanediperic acid or phthalimidopercarboxylic acids, optionally on aromatics may be substituted. In addition, the addition of small amounts Known bleach stabilizers such as phosphonates, borates or metaborates and metasilicates as well as magnesium salts such as Magnesium sulfate may be useful.
