Definitions
- the present invention relates to automatic dishwashing detergents and methods of using these agents.
- the invention relates to automatic dishwashing detergents which contain nonionic surfactants which have particularly low viscosities in aqueous solution.
- Machine dishwashing in home dishwashers is a process that is radically different from washing clothes in home washing machines. While in a washing machine the material to be cleaned is permanently moved in the liquor and in this way the cleaning is mechanically assisted, in a dishwasher the rinsing liquor is applied to the surfaces to be cleaned by a spray system. There, the cleaning liquor must automatically counteract even stubborn dirt, without any support by mechanical influences occurs. The level of performance of automatic dishwashing detergents must therefore be incomparably higher than that of conventional laundry detergents.
- the agents to be provided should be superior to conventional agents even in comparison to lower doses, especially on greasy soils.
- the funds should be used both as a conventional machine dishwashing detergent ("cleaner") in Powder or granule form or as a tablet or pourable offer form, as well as a combination product ("2in1" products which combine cleaners and rinse aid in combination and "3in1" products which combine cleaners, rinse aid and salt substitute) ,
- automatic dishwashing detergents which satisfy the abovementioned requirement profile can be provided if they contain builders and certain nonionic surfactants and optionally further ingredients of detergents.
- the present invention relates to automatic dishwashing compositions containing builder (s), surfactant (s) and optionally further ingredients, characterized in that they contain 0.1 to 50 wt .-% of one or more nonionic surfactants of the general formula I.
- R 1 is a straight-chain or branched, saturated or mono- or polyunsaturated C 6-24 alkyl or alkenyl radical; each group R 2 or R 3 is independently selected from -CH 3 ; -CH 2 CH 3 , -CH 2 CH 2 -CH 3 , CH (CH 3 ) 2 and the indices w, x, y, z independently of one another represent integers from 1 to 6 which contain surfactants at a concentration of 0, 01 g / l in distilled water have a diffusion coefficient of at least 9 - 10 -11 m 2 s -1 .
- Another object of the present invention is a machine dishwashing process in which a dishwashing detergent according to the invention is used.
- the diffusion coefficient can be calculated according to the theory of Fainerman et al. (Colloids and Surfaces A, 90 (1994) 213-224 ) from the measurement of the dynamic surface tension.
- the higher diffusion coefficients of the surfactant at high concentrations causes a significantly improved flow behavior of the overall formulation of surfaces treated with the cleaning agents.
- the surfactants used according to the invention wet the surfaces quickly and, above all, uniformly, so that the film of the rinse solution runs off uniformly on the dishes and does not break open prematurely. In this way, stain and schlierenlose surfaces and thus improved rinse results are obtained.
- the surfactant has even higher diffusion coefficients in a highly concentrated aqueous solution.
- erfundgsfelde agents are preferred in which the / the nonionic (s) surfactant (s) at a concentration of 0.01 g / l in distilled water has a diffusion coefficient of at least 9.5 ⁇ 10 -11 m 2 s -1 , preferably of at least 1 ⁇ 10 -10 m 2 s -1 and in particular of at least 2.5 ⁇ 10 -10 m 2 s -1 .
- Particularly preferred machine dishwasher detergents according to the invention contain one or more nonionic surfactant (s) which, at a concentration of 0.01 g / l in distilled water, have a diffusion coefficient of at least 5 ⁇ 10 -10 m 2 s -1 , preferably of at least 1 ⁇ 10 -9 m 2 s -1 and in particular of at least 5 ⁇ 10 -9 m 2 s -1 .
- nonionic surfactant s
- the diffusion coefficient of the present invention contained in the surfactants in aqueous solutions it may be advantageous for certain formulations when the surfactants are liquid at room temperature. This has, in addition to the easier processability with powdered or granular agents, the additional advantage that the surfactants do not have to be melted during processing, whereby the manufacturing costs can be further reduced.
- Nonionic surfactants which have a diffusion coefficient of at least 9 ° 10 -11 m 2 s -1 at a concentration of 0.01 g / l in distilled water can have a molecular structure of different composition. Depending on the type and length of the hydrophobic and the hydrophilic radical in the molecule, the properties of the surfactants can be controlled so that desired properties are present.
- nonionic surfactants having the properties described above are used in the inventive compositions in amounts of 0.1 to 50 wt .-%, each based on the total agent.
- Preferred automatic dishwashing agents according to the invention contain the nonionic surfactant (s) in amounts of from 0.5 to 40% by weight, preferably from 1 to 30 Wt .-%, particularly preferably from 2.5 to 25 wt .-% and in particular from 5 to 20 wt .-%, each based on the total agent.
- Nonionic surfactants used in the context of the present invention are low-foaming nonionic surfactants which have alternating ethylene oxide and alkylene oxide units, one to ten EO or AO groups being bonded to one another before one block is followed by the other groups.

Abstract
Description
Die vorliegende Erfindung betrifft maschinelle Geschirrspülmittel und Methoden zur Anwendung dieser Mittel. Im Speziellen betrifft die Erfindung maschinelle Geschirrspülmittel, welche nichtionische Tenside enthalten, die in wäßriger Lösung besonders niedrige Viskositäten aufweisen.The present invention relates to automatic dishwashing detergents and methods of using these agents. In particular, the invention relates to automatic dishwashing detergents which contain nonionic surfactants which have particularly low viscosities in aqueous solution.
Maschinelles Geschirrspülen in Hauhaltsgeschirrspülmaschinen ist ein Prozeß, der sich vom Wäschewaschen in Haushaltswaschmaschinen grundlegend unterscheidet. Während in einer Waschmaschine das zu reinigende Gut permanent in der Flotte bewegt und auf diese Weise die Reinigung mechanisch unterstützt wird, wird in einer Geschirrspülmaschine die Spülflotte durch ein Sprühsystem auf die zu reinigenden Oberflächen aufgetragen. Dort muß die Reinigungsflotte selbsttätig auch hartnäckigen Verschmutzungen entgegenwirken, ohne daß eine Unterstützung durch mechanische Einflüsse eintritt. Das Leistungsniveau von maschinellen Geschirrspülmitteln muß deshalb ungleich höher sein als das herkömmlicher Textilwaschmittel.Machine dishwashing in home dishwashers is a process that is radically different from washing clothes in home washing machines. While in a washing machine the material to be cleaned is permanently moved in the liquor and in this way the cleaning is mechanically assisted, in a dishwasher the rinsing liquor is applied to the surfaces to be cleaned by a spray system. There, the cleaning liquor must automatically counteract even stubborn dirt, without any support by mechanical influences occurs. The level of performance of automatic dishwashing detergents must therefore be incomparably higher than that of conventional laundry detergents.
Zusätzlich geht der Trend beim maschinellen Geschirrspülen aus ökologischen Gründen zu immer niedrigeren Temperaturen, immer kürzeren Spülzyklen und einer reduzierten Dosierung von Reinigungsmitteln, wobei in einigen Ländern auch Restriktionen bezüglich des Einsatzes bestimmter Inhaltsstoffe (beispielsweise Phosphate) zu beachten sind.In addition, the trend in automatic dishwashing for ecological reasons to ever lower temperatures, increasingly shorter rinsing cycles and a reduced dosage of detergents, in some countries, restrictions on the use of certain ingredients (for example, phosphates) are observed.
Die Leistungsanforderungen an moderne maschinelle Geschirrspülmittel steigen unter den oben genannten Rahmenbedingungen stetig an. Im Zuge dieser erhöhten Leistungsanforderungen besteht ein ständiger Bedarf nach leistungsgesteigerten maschinellen Geschirrspülmitteln, die in niederiger Dosierung auch bei niedrigen Temperaturen und kurzen Spülzeiten hohe Reinigungsleistungen erzielen.The performance requirements of modern automatic dishwashing detergents are steadily increasing under the above mentioned conditions. In the course of these increased performance requirements there is a constant need for performance-enhanced automatic dishwashing detergents which achieve high cleaning performance in low doses even at low temperatures and short rinsing times.
So offenbart die internationale Anmeldung
Der vorliegenden Erfindung lag die Aufgabe zugrunde, maschinelle Geschirrspülmittel bereitzustellen, die den erhöhten Leistungsanforderungen gerecht werden. Die bereitzustellenden Mittel sollten dabei insbesondere an fettigen Verschmutzungen herkömmlichen Mitteln auch bei im Vergleich geringerer Dosierung überlegen sein. Zusätzlich sollten die Mittel sowohl als herkömmliche maschinelle Geschirrspülmitttel ("Reiniger") in Pulver- oder Granulatform bzw. als Tablette oder gießbare Angebotsform bereitgestellt werden können, als auch als Kombinationsprodukt ("2in1"-Produkte, die Reiniger und Klarspüler in sich vereinen sowie "3in1"-Produkte, welche Reiniger, Klarspüler und Salzersatz in sich vereinen).It is an object of the present invention to provide automatic dishwashing detergents which meet the increased performance requirements. The agents to be provided should be superior to conventional agents even in comparison to lower doses, especially on greasy soils. In addition, the funds should be used both as a conventional machine dishwashing detergent ("cleaner") in Powder or granule form or as a tablet or pourable offer form, as well as a combination product ("2in1" products which combine cleaners and rinse aid in combination and "3in1" products which combine cleaners, rinse aid and salt substitute) ,
Es wurde nun gefunden, daß sich maschinelle Geschirrspülmittel, die dem vorstehend genannten Anforderungsprofil genügen, bereitstellen lassen, wenn sie Gerüststoffe und bestimmte nichtionische Tenside sowie optional weitere Inhaltsstoffe von Reinigungsmitteln enthalten.It has now been found that automatic dishwashing detergents which satisfy the abovementioned requirement profile can be provided if they contain builders and certain nonionic surfactants and optionally further ingredients of detergents.

Der Diffusionskoeffizient läßt sich dabei nach der Theorie von
Nach der Theorie von Fainerman, die bei kurzen Oberflächenaltern und kleinen Konzentrationen den Oberflächenfilm als ein ideales Gas modelliert, berechnet sich der Oberflächendruck P(t) = s0 - s(t) für kleine Oberflächenalter und kleine Oberflächenkonzentrationen zu
Daraus kann man den Diffusionskoeffizient durch die Gleichung
berechnen, wobei m die Steigung der Geraden in einer Auftragung P gegen t1/2 ist.From this one can get the diffusion coefficient by the equation
where m is the slope of the straight line in a plot P versus t 1/2 .

Die größeren Diffusionskoeffizienten des Tensids bei hohen Konzentrationen bewirkt ein deutlich verbessertes Ablaufverhalten der Gesamtformulierung von mit den Reinigungsmitteln behandelten Oberflächen. Die erfindungsgemäß eingesetzten Tenside benetzen dabei die Oberflächen schnell und vor allem gleichmäßig, so daß der Film der Klarspüllösung auf dem Geschirr gleichmäßig abläuft und nicht frühzeitig aufreißt. Auf diese Weise werden flecken- und schlierenlose Oberflächen und damit verbesserte Klarspülergebnisse erhalten.The higher diffusion coefficients of the surfactant at high concentrations causes a significantly improved flow behavior of the overall formulation of surfaces treated with the cleaning agents. The surfactants used according to the invention wet the surfaces quickly and, above all, uniformly, so that the film of the rinse solution runs off uniformly on the dishes and does not break open prematurely. In this way, stain and schlierenlose surfaces and thus improved rinse results are obtained.
In bevorzugten Ausführungsformen der vorliegenden Erfindung weist das Tensid in einer hochkonzentrierten wäßrigen Lösung noch höhere Diffusionskoeffizienten auf. Hier sind erfundgsgemäße Mittel bevorzugt, bei denen das/die nichtionische(n) Tensid(e) bei einer Konzentration von 0,01 g/l in destilliertem Wasser einen Diffusionskoeffizienten von mindestens 9,5 ∘ 10-11 m2s-1, vorzugsweise von mindestens 1 ∘ 10-10 m2s-1 und insbesondere von mindestens 2,5 ∘ 10-10 m2s-1 aufweisen.In preferred embodiments of the present invention, the surfactant has even higher diffusion coefficients in a highly concentrated aqueous solution. Here, erfundgsgemäße agents are preferred in which the / the nonionic (s) surfactant (s) at a concentration of 0.01 g / l in distilled water has a diffusion coefficient of at least 9.5 ∘ 10 -11 m 2 s -1 , preferably of at least 1 ∘ 10 -10 m 2 s -1 and in particular of at least 2.5 ∘ 10 -10 m 2 s -1 .
Besonders bevorzugte erfindungsgemäße maschinelle Geschirrspülmittel enthalten ein oder mehrere nichtionische(s) Tensid(e), das/die bei einer Konzentration von 0,01 g/l in destilliertem Wasser einen Diffusionskoeffizienten von mindestens 5 ∘ 10-10 m2s-1, vorzugsweise von mindestens 1 ∘ 10-9 m2s-1 und insbesondere von mindestens 5 ∘ 10-9 m2s-1 aufweisen.Particularly preferred machine dishwasher detergents according to the invention contain one or more nonionic surfactant (s) which, at a concentration of 0.01 g / l in distilled water, have a diffusion coefficient of at least 5 × 10 -10 m 2 s -1 , preferably of at least 1 ∘ 10 -9 m 2 s -1 and in particular of at least 5 ∘ 10 -9 m 2 s -1 .
Unabhängig vom Diffusionskoeffizienten der erfindungsgemäß in den Mitteln enthaltenen Tenside in wäßrigen Lösungen kann es für bestimmte Formulierungen von Vorteil sein, wenn die Tenside bei Raumtemperatur flüssig sind. Dies hat neben der leichteren Verarbeitbarkeit bei pulver- oder granulatförmigen Mitteln den zusätzlichen Vorteil, daß die Tenside bei der Verarbeitung nicht aufgeschmolzen werden müssen, wodurch sich die Herstellkosten weiter senken lassen.Regardless of the diffusion coefficient of the present invention contained in the surfactants in aqueous solutions, it may be advantageous for certain formulations when the surfactants are liquid at room temperature. This has, in addition to the easier processability with powdered or granular agents, the additional advantage that the surfactants do not have to be melted during processing, whereby the manufacturing costs can be further reduced.
Nichtionische Tenside, die bei einer Konzentration von 0,01 g/l in destilliertem Wasser einen Diffusionskoeffizienten von mindestens 9 ° 10-11 m2s-1 aufweisen, können molekular unterschiedlich aufgebaut sein. Je nach Art und Länge des hydrophoben und des hydrophilen Restes im Molekül können die Eigenschaften der Tenside so gesteuert werden, daß wunschgemäße Eigenschaften vorliegen.Nonionic surfactants which have a diffusion coefficient of at least 9 ° 10 -11 m 2 s -1 at a concentration of 0.01 g / l in distilled water can have a molecular structure of different composition. Depending on the type and length of the hydrophobic and the hydrophilic radical in the molecule, the properties of the surfactants can be controlled so that desired properties are present.

Besonders bevorzugte Werte für x liegen im Bereich von 1 bis 20, insbesondere von 6 bis 15.in which R 1 and R 2 are linear or branched, saturated or unsaturated, aliphatic or aromatic hydrocarbon radicals having 1 to 30 carbon atoms, R 3 is H or a methyl, ethyl, n-propyl, iso-propyl, n- Butyl, 2-butyl or 2-methyl-2-butyl radical, x for values between 1 and 30, k and j for values between 1 and 12, preferably between 1 and 5 stand. If the value x ≥ 2, each R 3 in the above formula may be different. R 1 and R 2 are preferably linear or branched, saturated or unsaturated, aliphatic or aromatic hydrocarbon radicals having 6 to 22 carbon atoms, with radicals having 8 to 18 carbon atoms being particularly preferred. For the radical R 3 , H, -CH 3 or -CH 2 CH 3 are particularly preferred. Particularly preferred values for x are in the range from 1 to 20, in particular from 6 to 15.
Wie vorstehend beschrieben, kann jedes R3 in der obenstehenden Formel unterschiedlich sein, falls x ≥ 2 ist. Hierdurch kann die Alkylenoxideinheit in der eckigen Klammer variiert werden. Steht x beispielsweise für 3, kann der Rest R3 ausgewählt werden, um Ethylenoxid- (R3 = H) oder Propylenoxid- (R3 = CH3) Einheiten zu bilden, die in jedweder Reihenfolge aneinandergefügt sein können, beispielsweise (EO)(PO)(EO), (EO)(EO)(PO), (EO)(EO)(EO), (PO)(EO)(PO), (PO)(PO)(EO) und (PO)(PO)(PO). Der Wert 3 für x ist hierbei beispielhaft gewählt worden und kann durchaus größer sein, wobei die Variationsbreite mit steigenden x-Werten zunimmt und beispielsweise eine große Anzahl (EO)-Gruppen, kombiniert mit einer geringen Anzahl (PO)-Gruppen einschließt, oder umgekehrt.As described above, each R 3 in the above formula may be different if x ≥ 2. As a result, the alkylene oxide unit in the square bracket can be varied. For example, when x is 3, the radical R 3 can be selected to form ethylene oxide (R 3 = H) or propylene oxide (R 3 = CH 3 ) units which may be joined in any order, for example (EO) ( PO) (EO), (EO) (EO) (PO), (EO) (EO) (EO), (PO) (EO) (PO), (PO) (PO) (EO) and (PO) ( PO) (PO). The value 3 for x has been selected here by way of example and may well be greater, with the variation width increasing with increasing x values and including, for example, a large number (EO) groups combined with a small number (PO) groups, or vice versa ,

Daneben können weitere Inhaltsstoffe zugegen sein, wobei erfindungsgemäße maschinelle Geschirrspülmittel bevorzugt sind, die zusätzlich einen oder mehrere Stoffe aus der Gruppe der Acidifizierungsmittel, Chelatkomplexbildner oder der belagsinhibierenden Polymere enthalten.In addition to builders, bleaches, bleach activators, enzymes, silver protectants, dyes and fragrances, etc., are preferred ingredients of automatic dishwashing detergents. In addition, further ingredients may be present, automatic dishwashing agents according to the invention being preferred which additionally contain one or more substances from the group of acidifying agents, chelating agents or coating-inhibiting polymers.
Als Acidifizierungsmittel bieten sich sowohl anorganische Säuren als auch organische Säuren an, sofern diese mit den übrigen Inhaltsstoffen verträglich sind. Aus Gründen des Verbraucherschutzes und der Handhabungssicherheit sind insbesondere die festen Mono-, Oligo-und Polycarbonsäuren einsetzbar. Aus dieser Gruppe wiederum bevorzugt sind Citronensäure, Weinsäure, Bernsteinsäure, Malonsäure, Adipinsäure, Maleinsäure, Fumarsäure, Oxalsäure sowie Polyacrylsäure.

Eine weitere mögliche Gruppe von Inhaltsstoffen stellen die Chelatkomplexbildner dar. Chelatkomplexbildner sind Stoffe, die mit Metallionen cyclische Verbindungen bilden, wobei ein einzelner Ligand mehr als eine Koordinationsstelle an einem Zentralatom besetzt, d. h. mind. "zweizähnig" ist. In diesem Falle werden also normalerweise gestreckte Verbindungen durch Komplexbildung über ein Ion zu Ringen geschlossen. Die Zahl der gebundenen Liganden hängt von der Koordinationszahl des zentralen Ions ab.Another possible group of ingredients are the chelating agents. Chelating agents are substances which form cyclic compounds with metal ions, with a single ligand occupying more than one coordination site on a central atom, i. H. at least "bidentate". In this case, normally stretched compounds are closed by complex formation via an ion into rings. The number of bound ligands depends on the coordination number of the central ion.
Gebräuchliche und im Rahmen der vorliegenden Erfindung bevorzugte Chelatkomplexbilder sind beispielsweise Polyoxycarbonsäuren, Polyamine, Ethylendiamintetraessigsäure (EDTA) und Nitrilotriessigsäure (NTA). Auch komplexbildende Polymere, also Polymere, die entweder in der Hauptkette selbst oder seitenständig zu dieser funktionelle Gruppen tragen, die als Liganden wirken können und mit geeigneten Metall-Atomen in der Regel unter Bildung von ChelatKomplexen reagieren, sind erfindungsgemäß einsetzbar. Die Polymer-gebundenen Liganden der entstehenden Metall-Komplexe können dabei aus nur einem Makromolekül stammen oder aber zu verschiedenen Polymerketten gehören. Letzteres führt zur Vernetzung des Materials, sofern die komplexbildenden Polymere nicht bereits zuvor über kovalente Bindungen vernetzt waren.Common and preferred chelating agents in the context of the present invention are, for example, polyoxycarboxylic acids, polyamines, ethylenediaminetetraacetic acid (EDTA) and nitrilotriacetic acid (NTA). Also, complex-forming polymers, ie polymers which carry functional groups either in the main chain itself or laterally to it, which can act as ligands and react with suitable metal atoms generally with the formation of chelate complexes, can be used according to the invention. The polymer-bound ligands of the resulting metal complexes can originate from only one macromolecule or belong to different polymer chains. The latter leads to the crosslinking of the material, provided that the complex-forming polymers were not previously crosslinked via covalent bonds.
Komplexierende Gruppen (Liganden) üblicher komplexbildender Polymere sind Iminodiessigsäure-, Hydroxychinolin-, Thioharnstoff-, Guanidin-, Dithiocarbamat-, Hydroxamsäure-, Amidoxim-, Aminophosphorsäure-, (cycl.) Polyamino-, Mercapto-, 1,3-Dicarbonyl- und Kronenether-Reste mit z. T. sehr spezif. Aktivitäten gegenüber Ionen unterschiedlicher Metalle. Basispolymere vieler auch kommerziell bedeutender komplexbildender Polymere sind Polystyrol, Polyacrylate, Polyacrylnitrile, Polyvinylalkohole, Polyvinylpyridine und Polyethylenimine. Auch natürliche Polymere wie Cellulose, Stärke od. Chitin sind komplexbildende Polymere.

Natural polymers such as cellulose, starch or chitin are also complex-forming polymers. In addition, these can be provided by polymer-analogous transformations with other ligand functionalities.

Als Polycarbonsäuren a) werden im Rahmen dieser Patentanmeldung Carbonsäuren -auch Monocarbonsäuren- verstanden, bei denen die Summe aus Carboxyl- und den im Molekül enthaltenen Hydroxylgruppen mindestens 5 beträgt. Komplexbildner aus der Gruppe der stickstoffhaltigen Polycarbonsäuren, insbesondere EDTA, sind bevorzugt. Bei den erfindungsgemäß erforderlichen alkalischen pH-Werten der Behandlungslösungen liegen diese Komplexbilner zumindest teilweise als Anionen vor. Es ist unwesentlich, ob sie in Form der Säuren oder in Form von Salzen eingebracht werden. Im Falle des Einsatzes als Salze sind Alkali-, Ammonium- oder Alkylammoniumsalze, insbesondere Natriumsalze, bevorzugt.For the purposes of this patent application, polycarboxylic acids a) are understood as meaning carboxylic acids, including monocarboxylic acids, in which the sum of carboxyl and the hydroxyl groups contained in the molecule is at least 5. Complexing agents from the group of nitrogen-containing polycarboxylic acids, in particular EDTA, are preferred. In the case of the alkaline pH values of the treatment solutions required according to the invention, these complexing agents are at least partially present as anions. It is irrelevant whether they are introduced in the form of acids or in the form of salts. In the case of use as salts, alkali metal, ammonium or alkylammonium salts, in particular sodium salts, are preferred.
Belagsinhibierende Polymere können ebenfalls in den erfindungsgemäßen Mitteln enthalten sein.
Diese Stoffe, die chemisch verschieden aufgebaut sein könne, stammen beispielsweise aus den Gruppen der niedermolekularen Polyacrylate mit Molmassen zwischen 1000 und 20.000 Dalton, wobei Polymere mit Molmassen unter 15.000 Dalton bevorzugt sind.Scale-inhibiting polymers can likewise be present in the agents according to the invention.
These substances, which could be constructed chemically different, for example, from the groups of low molecular weight polyacrylates having molecular weights between 1000 and 20,000 daltons, with polymers having molecular weights below 15,000 daltons are preferred.
Belagsinhibierende Polymere können auch Cobuildereigenschaften aufweisen. Als organische Cobuilder können in den erfindungsgemäßen maschinellen Geschirrspülmitteln insbesondere Polycarboxylate / Polycarbonsäuren, polymere Polycarboxylate, Asparaginsäure, Polyacetale, Dextrine, weitere organische Cobuilder (siehe unten) sowie Phosphonate eingesetzt werden. Diese Stoffklassen werden nachfolgend beschrieben.Scale-inhibiting polymers may also have co-builder properties. As organic cobuilders, it is possible in particular to use polycarboxylates / polycarboxylic acids, polymeric polycarboxylates, aspartic acid, polyacetals, dextrins, further organic cobuilders (see below) and phosphonates in the dishwasher detergents according to the invention. These classes of substances are described below.
Brauchbare organische Gerüstsubstanzen sind beispielsweise die in Form ihrer Natriumsalze einsetzbaren Polycarbonsäuren, wobei unter Polycarbonsäuren solche Carbonsäuren verstanden werden, die mehr als eine Säurefunktion tragen. Beispielsweise sind dies Citronensäure, Adipinsäure, Bernsteinsäure, Glutarsäure, Äpfelsäure, Weinsäure, Maleinsäure, Fumarsäure, Zuckersäuren, Aminocarbonsäuren, Nitrilotriessigsäure (NTA), sofern ein derartiger Einsatz aus ökologischen Gründen nicht zu beanstanden ist, sowie Mischungen aus diesen. Bevorzugte Salze sind die Salze der Polycarbonsäuren wie Citronensäure, Adipinsäure, Bernsteinsäure, Glutarsäure, Weinsäure, Zuckersäuren und Mischungen aus diesen.Useful organic builder substances are, for example, the polycarboxylic acids which can be used in the form of their sodium salts, polycarboxylic acids meaning those carboxylic acids which carry more than one acid function. These are, for example, citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), if such use is not objectionable for ecological reasons, and mixtures of these. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures thereof.
Auch die Säuren an sich können eingesetzt werden. Die Säuren besitzen neben ihrer Builderwirkung typischerweise auch die Eigenschaft einer Säuerungskomponente und dienen somit auch zur Einstellung eines niedrigeren und milderen pH-Wertes von Wasch- oder Reinigungsmitteln. Insbesondere sind hierbei Citronensäure, Bernsteinsäure, Glutarsäure, Adipinsäure, Gluconsäure und beliebige Mischungen aus diesen zu nennen.The acids themselves can also be used. In addition to their builder action, the acids typically also have the property of an acidifying component and thus also serve to set a lower and milder pH of detergents or cleaners. In particular, citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any desired mixtures of these can be mentioned here.
Als Builder bzw. Belagsinhibitor sind weiter polymere Polycarboxylate geeignet, dies sind beispielsweise die Alkalimetallsalze der Polyacrylsäure oder der Polymethacrylsäure, beispielsweise solche mit einer relativen Molekülmasse von 500 bis 70000 g/mol.As a builder or coating inhibitor further polymeric polycarboxylates are suitable, these are, for example, the alkali metal salts of polyacrylic acid or polymethacrylic acid, for example those having a molecular weight of 500 to 70000 g / mol.
Bei den für polymere Polycarboxylate angegebenen Molmassen handelt es sich im Sinne dieser Schrift um gewichtsmittlere Molmassen Mw der jeweiligen Säureform, die grundsätzlich mittels Gelpermeationschromatographie (GPC) bestimmt wurden, wobei ein UV-Detektor eingesetzt wurde. Die Messung erfolgte dabei gegen einen externen Polyacrylsäure-Standard, der aufgrund seiner strukturellen Verwandtschaft mit den untersuchten Polymeren realistische Molgewichtswerte liefert. Diese Angaben weichen deutlich von den Molgewichtsangaben ab, bei denen Polystyrolsulfonsäuren als Standard eingesetzt werden. Die gegen Polystyrolsulfonsäuren gemessenen Molmassen sind in der Regel deutlich höher als die in dieser Schrift angegebenen Molmassen.For the purposes of this document, the molecular weights stated for polymeric polycarboxylates are weight-average molar masses M w of the particular acid form, which were determined in principle by means of gel permeation chromatography (GPC), a UV detector being used. The measurement was carried out against an external polyacrylic acid standard, which provides realistic molecular weight values due to its structural relationship with the polymers investigated. These data differ significantly from the molecular weight data, in which polystyrene sulfonic acids are used as standard. The molar masses measured against polystyrenesulfonic acids are generally significantly higher than the molecular weights specified in this document.
Geeignete Polymere sind insbesondere Polyacrylate, die bevorzugt eine Molekülmasse von 500 bis 20000 g/mol aufweisen. Aufgrund ihrer überlegenen Löslichkeit können aus dieser Gruppe wiederum die kurzkettigen Polyacrylate, die Molmassen von 1000 bis 10000 g/mol, und besonders bevorzugt von 1000 bis 4000 g/mol, aufweisen, bevorzugt sein.Suitable polymers are in particular polyacrylates, which preferably have a molecular weight of 500 to 20,000 g / mol. Because of their superior solubility, this group may in turn, the short-chain polyacrylates, the molar masses of 1000 to 10,000 g / mol, and particularly preferably from 1000 to 4000 g / mol, have to be preferred.
Besonders bevorzugt werden in den erfindungsgemäßen Mitteln sowohl Polyacrylate als auch Copolymere aus ungesättigten Carbonsäuren, Sulfonsäuregruppen-haltigen Monomeren sowie gegebenenfalls weiteren ionischen oder nichtionogenen Monomeren eingesetzt.

The sulfonic acid group-containing copolymers are described in detail below.

Als besonders geeignet haben sich Copolymere der Acrylsäure mit Maleinsäure erwiesen, die 50 bis 90 Gew.-% Acrylsäure und 50 bis 10 Gew.-% Maleinsäure enthalten. Ihre relative Molekülmasse, bezogen auf freie Säuren, beträgt im allgemeinen 2000 bis 70000 g/mol, vorzugsweise 20000 bis 50000 g/mol und insbesondere 30000 bis 40000 g/mol.Also suitable are copolymeric polycarboxylates, in particular those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their relative molecular weight, based on free acids, is generally from 2000 to 70000 g / mol, preferably from 20,000 to 50,000 g / mol and in particular from 30,000 to 40,000 g / mol.
Die (co-)polymeren Polycarboxylate können entweder als Pulver oder als wäßrige Lösung eingesetzt werden. Der Gehalt der Mittel an (co-)polymeren Polycarboxylaten beträgt vorzugsweise 0,5 bis 20 Gew.-%, insbesondere 3 bis 10 Gew.-%.The (co) polymeric polycarboxylates can be used either as a powder or as an aqueous solution. The content of (co) polymeric polycarboxylates in the compositions is preferably 0.5 to 20% by weight, in particular 3 to 10% by weight.
Insbesondere bevorzugt sind auch biologisch abbaubare Polymere aus mehr als zwei verschiedenen Monomereinheiten, beispielsweise solche, die als Monomere Salze der Acrylsäure und der Maleinsäure sowie Vinylalkohol bzw. Vinylalkohol-Derivate oder die als Monomere Salze der Acrylsäure und der 2-Alkylallylsulfonsäure sowie Zucker-Derivate enthalten. Weitere bevorzugte Copolymere sind solche, die als Monomere vorzugsweise Acrolein und Acrylsäure/Acrylsäuresalze bzw. Acrolein und Vinylacetat aufweisen.Also particularly preferred are biodegradable polymers of more than two different monomer units, for example those which contain as monomers salts of acrylic acid and maleic acid and vinyl alcohol or vinyl alcohol derivatives or as monomers salts of acrylic acid and 2-alkylallylsulfonic acid and sugar derivatives , Further preferred copolymers are those which preferably have as monomers acrolein and acrylic acid / acrylic acid salts or acrolein and vinyl acetate.
Ebenso sind als weitere bevorzugte Buildersubstanzen polymere Aminodicarbonsäuren, deren Salze oder deren Vorläufersubstanzen zu nennen. Besonders bevorzugt sind Polyasparaginsäuren bzw. deren Salze und Derivate, die neben Cobuilder-Eigenschaften auch eine bleichstabilisierende Wirkung aufweisen.Also to be mentioned as further preferred builders polymeric aminodicarboxylic acids, their salts or their precursors.

Weitere geeignete organische Buildersubstanzen sind Dextrine, beispielsweise Oligomere bzw. Polymere von Kohlenhydraten, die durch partielle Hydrolyse von Stärken erhalten werden können. Die Hydrolyse kann nach üblichen, beispielsweise säure- oder enzymkatalysierten Verfahren durchgeführt werden. Vorzugsweise handelt es sich um Hydrolyseprodukte mit mittleren Molmassen im Bereich von 400 bis 500000 g/mol. Dabei ist ein Polysaccharid mit einem Dextrose-Äquivalent (DE) im Bereich von 0,5 bis 40, insbesondere von 2 bis 30 bevorzugt, wobei DE ein gebräuchliches Maß für die reduzierende Wirkung eines Polysaccharids im Vergleich zu Dextrose, welche ein DE von 100 besitzt, ist. Brauchbar sind sowohl Maltodextrine mit einem DE zwischen 3 und 20 und Trockenglucosesirupe mit einem DE zwischen 20 und 37 als auch sogenannte Gelbdextrine und Weißdextrine mit höheren Molmassen im Bereich von 2000 bis 30000 g/mol.Further suitable organic builder substances are dextrins, for example oligomers or polymers of carbohydrates, which can be obtained by partial hydrolysis of starches. The hydrolysis can be carried out by customary, for example acid or enzyme catalyzed processes. Preferably, it is hydrolysis products having average molecular weights in the range of 400 to 500,000 g / mol. In this case, a polysaccharide with a dextrose equivalent (DE) in the range from 0.5 to 40, in particular from 2 to 30 is preferred, DE being a common measure of the reducing action of a polysaccharide compared to dextrose, which has a DE of 100 , is. Usable are both maltodextrins with a DE between 3 and 20 and dry glucose syrups with a DE between 20 and 37 and so-called yellow dextrins and white dextrins with higher molecular weights in the range from 2000 to 30,000 g / mol.
Bei den oxidierten Derivaten derartiger Dextrine handelt es sich um deren Umsetzungsprodukte mit Oxidationsmitteln, welche in der Lage sind, mindestens eine Alkoholfunktion des Saccharidrings zur Carbonsäurefunktion zu oxidieren. Ein an C6 des Saccharidrings oxidiertes Produkt kann besonders vorteilhaft sein.The oxidized derivatives of such dextrins are their reaction products with oxidizing agents which are capable of oxidizing at least one alcohol function of the saccharide ring to the carboxylic acid function. A product oxidized to C 6 of the saccharide ring may be particularly advantageous.
Auch Oxydisuccinate und andere Derivate von Disuccinaten, vorzugsweise Ethylendiamindisuccinat, sind weitere geeignete Cobuilder. Dabei wird Ethylendiamin-N,N'-disuccinat (EDDS) bevorzugt in Form seiner Natrium- oder Magnesiumsalze verwendet. Weiterhin bevorzugt sind in diesem Zusammenhang auch Glycerindisuccinate und Glycerintrisuccinate. Geeignete Einsatzmengen liegen in zeolithhaltigen und/oder silicathaltigen Formulierungen bei 3 bis 15 Gew.-%.Oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate, are other suitable co-builders.

Unter den Hydroxyalkanphosphonaten ist das 1-Hydroxyethan-1,1-diphosphonat (HEDP) von besonderer Bedeutung als Cobuilder. Es wird vorzugsweise als Natriumsalz eingesetzt, wobei das Dinatriumsalz neutral und das Tetranatriumsalz alkalisch (pH 9) reagiert. Als Aminoalkanphosphonate kommen vorzugsweise Ethylendiamintetramethylenphosphonat (EDTMP), Diethylentriaminpentamethylenphosphonat (DTPMP) sowie deren höhere Homologe in Frage. Sie werden vorzugsweise in Form der neutral reagierenden Natriumsalze, z. B. als Hexanatriumsalz der EDTMP bzw. als Hepta- und Octa-Natriumsalz der DTPMP, eingesetzt. Als Builder wird dabei aus der Klasse der Phosphonate bevorzugt HEDP verwendet. Die Aminoalkanphosphonate besitzen zudem ein ausgeprägtes Schwermetallbindevermögen. Dementsprechend kann es, insbesondere wenn die Mittel auch Bleiche enthalten, bevorzugt sein, Aminoalkanphosphonate, insbesondere DTPMP, einzusetzen, oder Mischungen aus den genannten Phosphonaten zu verwenden.Another class of substances with cobuilder properties are the phosphonates. These are, in particular, hydroxyalkane or aminoalkanephosphonates. Among the hydroxyalkane phosphonates, 1-hydroxyethane-1,1-diphosphonate (HEDP) is of particular importance as a co-builder.

When Builder is used from the class of phosphonates preferably HEDP. The aminoalkanephosphonates also have a pronounced heavy metal binding capacity. Accordingly, in particular if the agents also contain bleach, it may be preferable to use aminoalkanephosphonates, in particular DTPMP, or to use mixtures of the phosphonates mentioned.

Farb- und Duftstoffe können den erfindungsgemäßen maschinellen Geschirrspülmitteln zugesetzt werden, um den ästhetischen Eindruck der entstehenden Produkte zu verbessern und dem Verbraucher neben der Leistung ein visuell und sensorisch "typisches und unverwechselbares" Produkt zur Verfügung zu stellen. Als Parfümöle bzw. Duftstoffe können einzelne Riechstoffverbindungen, z.B. die synthetischen Produkte vom Typ der Ester, Ether, Aldehyde, Ketone, Alkohole und Kohlenwasserstoffe verwendet werden. Riechstoffverbindungen vom Typ der Ester sind z.B. Benzylacetat, Phenoxyethylisobutyrat, p-tert.-Butylcyclohexylacetat, Linalylacetat, Dimethylbenzylcarbinylacetat, Phenylethylacetat, Linalylbenzoat, Benzylformiat, Ethylmethylphenylglycinat, Allylcyclohexylpropionat, Styrallylpropionat und Benzylsalicylat. Zu den Ethern zählen beispielsweise Benzylethylether, zu den Aldehyden z.B. die linearen Alkanale mit 8-18 C-Atomen, Citral, Citronellal, Citronellyloxyacetaldehyd, Cyclamenaldehyd, Hydroxycitronellal, Lilial und Bourgeonal, zu den Ketonen z.B. die Jonone, α-Isomethylionon und Methylcedrylketon, zu den Alkoholen Anethol, Citronellol, Eugenol, Geraniol, Linalool, Phenylethylalkohol und Terpineol, zu den Kohlenwasserstoffen gehören hauptsächlich die Terpene wie Limonen und Pinen. Bevorzugt werden jedoch Mischungen verschiedener Riechstoffe verwendet, die gemeinsam eine ansprechende Duftnote erzeugen. Solche Parfümöle können auch natürliche Riechstoffgemische enthalten, wie sie aus pflanzlichen Quellen zugänglich sind, z.B. Pine-, Citrus-, Jasmin-, Patchouly-, Rosen- oder Ylang-Ylang-Öl. Ebenfalls geeignet sind Muskateller, Salbeiöl, Kamillenöl, Nelkenöl, Melissenöl, Minzöl, Zimtblätteröl, Lindenblütenöl, Wacholderbeeröl, Vetiveröl, Olibanumöl, Galbanumöl und Labdanumöl sowie Orangenblütenöl, Neroliol, Orangenschalenöl und Sandelholzöl.Dyes and fragrances can be added to the machine dishwasher detergents according to the invention in order to improve the aesthetic impression of the resulting products and to provide the consumer with a visually and sensory "typical and unmistakable" product in addition to performance. As perfume oils or fragrances, individual fragrance compounds, e.g. the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type are used. Fragrance compounds of the ester type are known e.g. Benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate, phenylethylacetate, linalylbenzoate, benzylformate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and benzylsalicylate.

Also suitable are muscatel, sage, chamomile, clove, lemon balm, mint, cinnamon, lime, juniper, vetiver, olibanum, galbanum and labdanum, and orange blossom, neroliol, orange peel and sandalwood.
Die Duftstoffe können direkt in die erfindungsgemäßen Reinigungsmittel eingearbeitet werden, es kann aber auch vorteilhaft sein, die Duftstoffe auf Träger aufzubringen, die die Haftung des Parfüms auf der Wäsche verstärken und durch eine langsamere Duftfreisetzung für langanhaltenden Duft der Textilien sorgen. Als solche Trägermaterialien haben sich beispielsweise Cyclodextrine bewährt, wobei die Cyclodextrin-Parfüm-Komplexe zusätzlich noch mit weiteren Hilfsstoffen beschichtet werden können.The fragrances can be incorporated directly into the detergents according to the invention, but it can also be advantageous to apply the fragrances to carriers, which enhance the adhesion of the perfume to the laundry and provide a slower fragrance release for long-lasting fragrance of the textiles. As such carrier materials, for example, cyclodextrins have been proven, the cyclodextrin-perfume complexes can be additionally coated with other excipients.
Um den ästhetischen Eindruck der erfindungsgemäß hergestellten Mittel zu verbessern, kann es (oder Teile davon) mit geeigneten Farbstoffen eingefärbt werden. Bevorzugte Farbstoffe, deren Auswahl dem Fachmann keinerlei Schwierigkeit bereitet, besitzen eine hohe Lagerstabilität und Unempfindlichkeit gegenüber den übrigen Inhaltsstoffen der Mittel und gegen Licht sowie keine ausgeprägte Substantivität gegenüber den mit den Mitteln zu behandelnden Substraten wie Glas, Keramik oder Kunststoffgeschirr, um diese nicht anzufärben.In order to improve the aesthetics of the compositions made according to the invention, it may (or parts thereof) be colored with suitable dyes. Preferred dyes, the selection of which presents no difficulty to the skilled person, have a high storage stability and insensitivity to the other ingredients of the agents and against light and no pronounced substantivity to the substrates to be treated with the agents such as glass, ceramic or plastic dishes, not to stain them.
Die erfindungsgemäßen Reinigungsmittel können zum Schutze des Spülgutes oder der Maschine Korrosionsinhibitoren enthalten, wobei besonders Silberschutzmittel im Bereich des maschinellen Geschirrspülens eine besondere Bedeutung haben. Einsetzbar sind die bekannten Substanzen des Standes der Technik. Allgemein können vor allem Silberschutzmittel ausgewählt aus der Gruppe der Triazole, der Benzotriazole, der Bisbenzotriazole, der Aminotriazole, der Alkylaminotriazole und der Übergangsmetallsalze oder -komplexe eingesetzt werden. Besonders bevorzugt zu verwenden sind Benzotriazol und/oder Alkylaminotriazol. Man findet in Reinigerformutierungen darüber hinaus häufig aktivchlorhaltige Mittel, die das Korrodieren der Silberoberfläche deutlich vermindern können. In chlorfreien Reinigern werden besonders Sauerstoff- und stickstoffhaltige organische redoxaktive Verbindungen, wie zwei- und dreiwertige Phenole, z. B. Hydrochinon, Brenzkatechin, Hydroxyhydrochinon, Gallussäure, Phloroglucin, Pyrogallol bzw. Derivate dieser Verbindungsklassen. Auch salz- und komplexartige anorganische Verbindungen, wie Salze der Metalle Mn, Ti, Zr, Hf, V, Co und Ce finden häufig Verwendung. Bevorzugt sind hierbei die Übergangsmetallsalze, die ausgewählt sind aus der Gruppe der Mangan und/oder Cobaltsalze und/oder -komplexe, besonders bevorzugt der Cobalt(ammin)-Komplexe, der Cobalt(acetat)-Komplexe, der Cobalt-(Carbonyl)-Komplexe, der Chloride des Cobalts oder Mangans und des Mangansulfats. Ebenfalls können Zinkverbindungen zur Verhinderung der Korrosion am Spülgut eingesetzt werden.The detergents according to the invention may contain corrosion inhibitors for the protection of the items to be washed or the machine, with silver protectants in particular being of particular importance in the field of automatic dishwashing. It is possible to use the known substances of the prior art. In general, silver protectants selected from the group of triazoles, benzotriazoles, bisbenzotriazoles, aminotriazoles, alkylaminotriazoles and transition metal salts or complexes can be used in particular. Particularly preferred to use are benzotriazole and / or alkylaminotriazole. In addition, active chlorine-containing agents are frequently found in cleaner formulations, which can markedly reduce the corrosion of the silver surface. In chlorine-free cleaners are particularly oxygen and nitrogen-containing organic redox-active compounds, such as di- and trihydric phenols, eg. As hydroquinone, pyrocatechol, hydroxyhydroquinone, gallic acid, phloroglucinol, pyrogallol or derivatives of these classes of compounds. Also, salt and complex inorganic compounds, such as salts of the metals Mn, Ti, Zr, Hf, V, Co and Ce are often used. Preferred here are the transition metal salts which are selected from the group of manganese and / or cobalt salts and / or complexes, more preferably the cobalt (amine) complexes, the cobalt (acetate) complexes, the cobalt (carbonyl) complexes , the chlorides of cobalt or manganese and manganese sulfate. Also, zinc compounds can be used to prevent corrosion on the items to be washed.
An maschinell gespültes Geschirr werden heute häufig höhere Anforderungen gestellt als an manuell gespültes Geschirr. So wird auch ein von Speiseresten völlig gereinigtes Geschirr dann als nicht einwandfrei bewertet, wenn es nach dem maschinellen Geschirrspülen noch weißliche, auf Wasserhärte oder anderen mineralischen Salzen beruhende Flecken aufweist, die mangels Netzmittel aus eingetrockneten Wassertropfen stammen. Um glasklares und fleckenloses Geschirr zu erhalten, setzt man daher heute mit Erfolg Klarspüler ein. Der Zusatz von Klarspüler am Ende des Spülprogramms sorgt dafür, daß das Wasser möglichst vollständig vom Spülgut abläuft, so daß die unterschiedlichen Oberflächen am Ende des Spülprogramms rückstandsfrei und makellos glänzend sind. Das maschinelle Reinigen von Geschirr in Haushaltsgeschirrspülmaschinen umfaßt üblicherweise einen Vorspülgang, einen Hauptspülgang und einen Klarspülgang, die von Zwischenspülgängen unterbrochen werden. Bei den meisten Maschinen ist der Vorspülgang für stark verschmutztes Geschirr zuschaltbar, wird aber nur in Ausnahmefällen vom Verbraucher gewählt, so daß in den meisten Maschinen ein Hauptspülgang, ein Zwischenspülgang mit reinem Wasser und ein Klarspülgang durchgeführt werden. Die Temperatur des Hauptspülgangs variiert dabei je nach Maschinentyp und Programmstufenwahl zwischen 40 und 65°C. Im Klarspülgang werden aus einem Dosiertank in der Maschine Klarspülmittel zugegeben, die üblicherweise als Hauptsbestandteil nichtionische Tenside enthalten. Solche Klarspüler liegen in flüssiger Form vor und sind im Stand der Technik breit beschrieben. Ihre Aufgabe besteht vornehmlich darin, Kalkflecken und Beläge auf dem Geschirr zu verhindern.Machine-washed dishes are often subject to more stringent requirements today than manually-washed dishes. So even a completely cleaned of leftovers dishes is then rated as not flawless if it has after dishwasher washing whitish, based on water hardness or other mineral salts stains that come from lack of wetting agent from dried water droplets. In order to obtain crystal-clear and spotless dishes, one uses therefore successfully today rinse aid. The addition of rinse aid at the end of the washing program ensures that the water runs as completely as possible from the items to be washed, so that the different surfaces at the end of the washing program are residue-free and flawless gloss. The automatic cleaning of dishes in household dishwashers usually includes a pre-wash, a main wash, and a rinse cycle interrupted by intermediate rinses. On most machines, the pre-rinse cycle for heavily soiled dishes can be switched on, but only in Exceptionally chosen by the consumer, so that in most machines, a main rinse, an intermediate rinse with pure water and a rinse cycle are performed. The temperature of the main wash cycle varies between 40 and 65 ° C, depending on the machine type and program level selection. In the rinse cycle, rinse aids are added from a dosing tank in the machine, which usually contain nonionic surfactants as the main constituent. Such rinse aids are in liquid form and are widely described in the art. Your task is primarily to prevent limescale and deposits on the dishes.
Die erfindungsgemäßen Mittel können als "normale" Reiniger formuliert werden, welche zusammen mit handelsüblichen Ergänzungsmitteln (Klarspüler, Regeneriersalz) eingesetzt werden. Mit besonderem Vorteil kann aber mit den erfindungsgemäßen Produkten auf die zusätzliche Dosierung von Klarspülmitteln verzichtet werden, da die erfindungsgemäß in den Mitteln enthaltenen Tenside mit hohen Diffusionskoeffizienten hervorragende Ablaufeigenschaften der Spülflotte bedingen und Beläge auf dem Geschirr im Vergleich zu herkömmlichen Tensiden deutlich verringern. Diese sogenannten "2in1"-Produkte führen zu einer Vereinfachung der Handhabung und nehmen dem Verbraucher die Last der zusätzlichen Dosierung zweier unterschiedlicher Produkte (Reiniger und Klarspüler) ab.The compositions according to the invention can be formulated as "normal" cleaners, which are used together with commercially available supplements (rinse aid, regenerating salt). With particular advantage but can be dispensed with the products of the invention to the additional dosage of rinse agents, since the invention contained in the surfactants with high diffusion coefficients cause excellent flow properties of the rinse and significantly reduce deposits on the dishes compared to conventional surfactants. These so-called "2in1" products lead to a simplification of handling and relieve the consumer of the burden of additional dosage of two different products (cleaner and rinse aid).
Selbst beim Einsatz von "2in1"-Produkten sind zum Betrieb einer Haushaltsgeschirrspülmaschine in Zeitabständen zwei Dosiervorgänge erforderlich, da nach einer bestimmten Anzahl von Spülvorgängen das Regeneriersalz im Wasserenthärtungssystem der Maschine nachgefüllt werden muß. Diese Wasserenthärtungssysteme bestehen aus lonenaustauscherpolymeren, welche das der Maschine zulaufende Hartwasser enthärten und im Anschluß an das Spülprogramm durch eine Spülung mit Salzwasser regeneriert werden.Even with the use of "2in1" products, two dosing operations are required at regular intervals to operate a domestic dishwasher, because after a certain number of rinses, the regeneration salt must be replenished in the water softening system of the machine. These water softening systems consist of ion exchange polymers which soften the hard water entering the machine and are regenerated by a rinsing with salt water following the washing program.
Es lassen sich aber auch erfindungsgemäße Produkte, welche als sogenannte "3in1"-Produkte die herkömmlichen Reiniger, Klarspüler und eine Salzersatzfunktion in sich vereinen, bereitstellen. Hierzu sind erfindungsgemäße maschinelle Geschirrspülmittel bevorzugt, die zusätzlich 0,1 bis 70 Gew.-% an Copolymeren aus
- i) ungesättigten Carbonsäuren
- ii) Sulfonsäuregruppen-haltigen Monomeren
- iii) gegebenenfalls weiteren ionischen oder nichtionogenen Monomeren
- i) unsaturated carboxylic acids
- ii) sulfonic acid group-containing monomers
- iii) optionally further ionic or nonionic monomers
Diese Copolymere bewirken, daß die mit solchen Mitteln behandelten Geschirrteile bei nachfolgenden Reinigungsvorgängen deutlich sauberer werden, als Geschirrteile, die mit herkömmlichen Mitteln gespült wurden.These copolymers cause the dishware treated with such agents to become significantly cleaner in subsequent cleanings than do the dishware which has been rinsed by conventional means.
Als zusätzlicher positiver Effekt tritt eine Verkürzung der Trocknungszeit der mit dem Reinigungsmittel behandelten Geschirrteile auf, d.h. der Verbraucher kann nach dem Ablauf des Reinigungsprogramms das Geschirr früher aus der Maschine nehmen und wiederbenutzen.As an additional positive effect, a shortening of the drying time of the dishes treated with the detergent occurs, i. the consumer can take the dishes from the machine earlier and reuse them after the cleaning program has ended.
