Description

Die vorliegende Patentanmeldung betrifft die Verstärkung der Reinigungsleistung von Waschmitteln beim Waschen von Textilien durch den Einsatz eines bestimmten schmutzablösevermögenden Polymers.The present patent application relates to enhancing the detergency of laundry detergents in the washing of textiles through the use of a particular soil release polymer.

Waschmittel enthalten neben den für den Waschprozess unverzichtbaren Inhaltsstoffen wie Tensiden und Buildermaterialien in der Regel weitere Bestandteile, die man unter dem Begriff Waschhilfsstoffe zusammenfassen kann und die so unterschiedliche Wirkstoffgruppen wie Schaumregulatoren, Vergrauungsinhibitoren, Bleichmittel, Bleichaktivatoren und Farbübertragungsinhibitoren umfassen. Zu derartigen Hilfsstoffen gehören auch Substanzen, welche der Wäschefaser schmutzabstoßende Eigenschaften verleihen und die, falls während des Waschvorgangs anwesend, das Schmutzablösevermögen der übrigen Waschmittelbestandteile unterstützen. Gleiches gilt sinngemäß auch für Reinigungsmittel für harte Oberflächen. Derartige schmutzablösevermögende Substanzen werden oft als "Soil-Release"-Wirkstoffe oder wegen ihres Vermögens, die behandelte Oberfläche, zum Beispiel der Faser, schmutzabstoßend auszurüsten, als "Soil-Repellents" bezeichnet. So ist beispielsweise aus dem US-amerikanischen Patent US 4 136 038 die schmutzablösevermögende Wirkung von Methylcellulose bekannt. Die europäische Patentanmeldung EP 0 213 729 offenbart die verringerte Redeposition bei Einsatz von Waschmitteln, die eine Kombination von Seife und nichtionischem Tensid mit Alkyl-Hydroxyalkyl-Cellulose enthalten. Aus der europäischen Patentanmeldung EP 0 213 730 sind Textilbehandlungsmittel bekannt, die kationische Tenside und nichtionische Celluloseether mit HLB-Werten von 3,1 bis 3,8 enthalten. Die US-amerikanische Patentschrift US 4 000 093 offenbart Waschmittel, die 0,1 Gew.-% bis 3 Gew.-% Alkyl-Cellulose, Hydroxyalkyl-Cellulose oder Alkyl-Hydroxyalkyl-Cellulose sowie 5 Gew.-% bis 50 Gew.-% Tensid enthalten, wobei die Tensidkomponente im wesentlichen aus C10- bis C13-Alkylsulfat besteht und bis zu 5 Gew.-% C14-Alkylsulfat und weniger als 5 Gew.-% Alkylsulfat mit Alkylresten von C15 und höher aufweist. Die US-amerikanische Patentschrift US 4 174 305 offenbart Waschmittel, die 0,1 Gew.-% bis 3 Gew.-% Alkyl-Cellulose, Hydroxyalkyl-Cellulose oder Alkyl-Hydroxyalkyl-Cellulose sowie 5 Gew.-% bis 50 Gew.-% Tensid enthalten, wobei die Tensidkomponente im wesentlichen aus C10- bis C12-Alkylbenzolsulfonat besteht und weniger als 5 Gew.-% Alkylbenzolsulfonat mit Alkylresten von C13 und höher aufweist. Die europäische Patentanmeldung EP 0 634 481 betrifft ein Waschmittel, das Alkalipercarbonat und ein oder mehrere nichtionische Cellulosederivate enthält. Ausdrücklich offenbart sind unter letzteren lediglich Hydroxyethylcellulose, Hydroxypropylcellulose und Methylcellulose sowie - im Rahmen der Beispiele - die Methyl-hydroxyethylcellulose Tylose® MH50, die Hydroxypropyl-methylcellulose Methocel® F4M und Hydroxybutylmethylcellulose. Die europäische Patentschrift EP 0 271 312 (P&G) betrifft schmutzablösevermögende Wirkstoffe, unter diesen Cellulosealkylether und Cellulosehydroxyalkylether (mit DS 1,5 bis 2,7 und Molmassen von 2000 bis 100000) wie Methylcellulose und Ethylcellulose, die mit Persauerstoffbleichmittel im Gewichtsverhältnis (bezogen auf den Aktivsauerstoffgehalt des Bleichmittels) von 10:1 bis 1:10 eingesetzt werden sollen. Aus der europäischen Patentschrift EP 0 948 591 B1 ist ein Waschmittel in flüssiger oder granularer Form bekannt, welches Geweben und Textilien, die damit gewaschen werden, Textilaussehensvorteile wie Pill-/Fusselverringerung, Antifarbverblassung, verbesserte Abriebbeständigkeit und/oder verstärkte Weichheit verleiht und das 1 bis 80 Gew.-% Tensid, 1 bis 80 Gew.-% organischen oder anorganischen Builder, 0,1 bis 80 Gew.-% eines hydrophob modifizierten nichtionischen Celluloseethers mit einem Molgewicht von 10 000 bis 2 000 000 enthält, wobei die Modifikation in der Anwesenheit von gegebenenfalls oligomerisierten (Oligomerisationsgrad bis zu 20) Ethylenoxy- oder 2-Propylenoxy-Ethereinheiten und von C8-24-Alkylsubstituenten besteht und die Alkylsubstituenten in Mengen von 0,1-5 Gew.-%, bezogen auf das Celluloseether-Material, vorhanden sein müssen.Detergents contain in addition to the indispensable for the washing process ingredients such as surfactants and builder materials usually further ingredients that can be summarized by the term washing aids and include as different drug groups such as foam regulators, grayness inhibitors, bleach, bleach activators and dye transfer inhibitors. Such adjuvants also include substances which impart soil repellency properties to the laundry fiber and, if present during the wash, aid the soil release properties of the remaining detergent ingredients. The same applies mutatis mutandis to cleaners for hard surfaces. Such soil release agents are often referred to as "soil release" agents or because of their ability to impart soil repellency to the treated surface, such as the fiber, as "soil repellents". For example, from the US patent US 4,136,038 the soil release ability of methyl cellulose is known. The European patent application EP 0 213 729 discloses the reduced redeposition when using detergents containing a combination of soap and nonionic surfactant with alkyl hydroxyalkyl cellulose. From the European patent application EP 0 213 730 Textile treatment agents are known which contain cationic surfactants and nonionic cellulose ethers with HLB values of 3.1 to 3.8. The US patent US 4,000,093 discloses detergents containing from 0.1% to 3% by weight of alkyl cellulose, hydroxyalkyl cellulose or alkyl hydroxyalkyl cellulose and from 5% to 50% by weight surfactant, wherein the surfactant component is substantially consists of C 10 - to C 13 -alkyl sulfate and up to 5 wt .-% C 14 alkyl sulfate and less than 5 wt .-% alkyl sulfate having alkyl radicals of C 15 and higher. The US patent US 4,174,305 discloses detergents containing from 0.1% to 3% by weight of alkyl cellulose, hydroxyalkyl cellulose or Alkyl-hydroxyalkyl cellulose and 5 wt .-% to 50 wt .-% surfactant, wherein the surfactant component consists essentially of C 10 - to C 12 -alkylbenzenesulfonate and less than 5 wt .-% alkylbenzenesulfonate with alkyl radicals of C 13 and has higher. The European patent application EP 0 634 481 relates to a detergent containing alkali metal percarbonate and one or more nonionic cellulose derivatives. The latter expressly disclose only hydroxyethylcellulose, hydroxypropylcellulose and methylcellulose and, in the examples, the methylhydroxyethylcellulose Tylose® MH50, the hydroxypropylmethylcellulose Methocel® F4M and hydroxybutylmethylcellulose. The European patent EP 0 271 312 (P & G) relates to soil release agents, among these cellulose alkyl ethers and cellulose hydroxyalkyl ethers (having DS 1.5 to 2.7 and molecular weights of 2,000 to 100,000) such as methylcellulose and ethylcellulose, with weight ratio of peroxygen bleach (based on the active oxygen content of the bleaching agent) of 10: 1 to 1:10 should be used. From the European patent EP 0 948 591 B1 For example, a detergent in liquid or granular form is known which imparts textile appearance benefits such as pilling / lint reduction, anti-color fading, improved abrasion resistance and / or enhanced softness to fabrics and textiles washed therewith, and from 1 to 80% by weight of surfactant, 1 to 80 wt .-% organic or inorganic builder, 0.1 to 80 wt .-% of a hydrophobically modified nonionic cellulose ether having a molecular weight of 10,000 to 2,000,000, wherein the modification in the presence of optionally oligomerized (degree of oligomerization up to 20 ) Ethyleneoxy or 2-propyleneoxy ether units and C 8-24 alkyl substituents and the alkyl substituents must be present in amounts of 0.1-5 wt .-%, based on the cellulose ether material.

Wegen ihrer chemischen Ähnlichkeit zu Polyesterfasern bei Textilien aus diesem Material besonders wirksame schmutzablösevermögende Wirkstoffe sind Copolyester, die Dicarbonsäureeinheiten, Alkylenglykoleinheiten und Polyalkylenglykoleinheiten enthalten. Schmutzablösevermögende Copolyester der genannten Art wie auch ihr Einsatz in Waschmitteln sind seit langer Zeit bekannt.Because of their chemical similarity to polyester fibers in textiles of this material particularly effective soil release agents are copolyesters containing dicarboxylic acid units, alkylene glycol units and polyalkylene glycol units. Dirt-releasing copolyesters of the type mentioned as well as their use in detergents have been known for a long time.

Aus der europäischen Patentanmeldung EP 272 033 sind zumindest anteilig durch C1-4-Alkyl- oder Acylreste endgruppenverschlossene Polyester mit Poly-propylenterephthalat- und Polyoxyethylenterephthalat-Einheiten bekannt. Das europäische Patent EP 274 907 beschreibt sulfoethyl-endgruppenverschlossene terephthalathaltige Soil-release-Polyester. In der europäischen Patentanmeldung EP 357 280 werden durch Sulfonierung ungesättigter Endgruppen Soil-Release-Polyester mit Terephthalat-, Alkylenglykol- und Poly-C2-4-Glykol-Einheiten hergestellt. Die deutsche Patentanmeldung DE 26 55 551 beschreibt die Umsetzung derartiger Polyester mit isocyanatgruppenhaltigen Polymeren und die Verwendung der so hergestellten Polymerisate gegen das Wiederaufziehen von Schmutz beim Waschen von synthetischen Fasern. Aus der deutschen Patentschrift DE 28 46 984 sind Waschmittel bekannt, die als schmutzablösevermögendes Polymer ein Umsetzungsprodukt eines Polyesters mit einem endständige Isocyanatgruppen enthaltenden Prepolymer, erhalten aus einem Diisocyanat und einem hydrophilen nichtionischem Macrodiol, enthalten. Die US-A- 2001/0036912 offenbart Schmutzablösende vermögende Polymere für Textilien aus Baumwolle und Baumwolle-Mischgewebe.For example, the German Offenlegungsschrift describes DT 16 17 141 a washing process using polyethylene terephthalate-polyoxyethylene glycol copolymers. The German disclosure DT 22 00 911 relates to detergents containing nonionic surfactant and a copolymer of polyoxyethylene glycol and polyethylene terephthalate. In the German patent application DT 22 53 063 acidic textile finishing agents are mentioned which contain a copolymer of a dibasic carboxylic acid and an alkylene or Cycloalkylenpolyglykol and optionally an alkylene or cycloalkylene glycol. Polymers of ethylene terephthalate and polyethylene oxide terephthalate in which the polyethylene glycol units have molecular weights of 750 to 5,000 and the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate is 50:50 to 90:10, and their use in detergents are disclosed in the German Patent DE 28 57 292 described. Polymers having a molecular weight of 15,000 to 50,000 of ethylene terephthalate and polyethylene oxide terephthalate, wherein the polyethylene glycol units have molecular weights of 1000 to 10,000 and the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate is 2: 1 to 6: 1, can according to the German Offenlegungsschrift DE 33 24 258 be used in detergents. The European patent EP 066 944 relates to textile treatment compositions containing a copolyester of ethylene glycol, polyethylene glycol, aromatic dicarboxylic acid and sulfonated aromatic dicarboxylic acid in certain molar ratios. From the European patent EP 185 427 For example, methyl or ethyl group-end capped polyesters having ethylene and / or propylene terephthalate and polyethylene oxide terephthalate units and detergents containing such soil release polymer are known. The European patent EP 241 984 relates to a polyester which in addition to oxyethylene groups and terephthalic acid units also contains substituted ethylene units and glycerol units. From the European patent EP 241 985 are known polyester containing in addition to oxyethylene groups and terephthalic acid units 1,2-propylene, 1,2-butylene and / or 3-methoxy-1,2-propylene and glycerol units and endgruppenverschlossen with C 1 - to C 4 alkyl groups are. The European patent EP 253 567 relates to soil release polymers having a molecular weight of 900 to 9000 of ethylene terephthalate and polyethylene oxide terephthalate, wherein the polyethylene glycol units have molecular weights of 300 to 3000 and the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate is 0.6 to 0.95. From the European patent application EP 272 033 are at least partially by C 1-4 alkyl or acyl radicals end-capped polyester with poly-propylene terephthalate and polyoxyethylene terephthalate units known. The European patent EP 274 907 describes sulfoethyl end-capped terephthalate-containing soil release polyesters. In the European patent application EP 357,280 are prepared by sulfonation of unsaturated end groups soil release polyester with terephthalate, alkylene glycol and poly-C 2-4 glycol units. The German patent application DE 26 55 551 describes the reaction of such polyesters with isocyanate group-containing polymers and the use of the polymers thus prepared against the repulping of dirt during the washing of synthetic fibers. From the German patent DE 28 46 984 Detergents are known which contain, as soil release-capable polymer, a reaction product of a polyester having a terminal isocyanate group-containing prepolymer obtained from a diisocyanate and a hydrophilic nonionic macrodiol. The US-A-2001/0036912 discloses soil release high net-worth polymers for cotton and cotton blended fabrics.

Die Mehrzahl der aus diesem umfangreichen Stand der Technik bekannten Polymere weist den Nachteil auf, daß sie bei Textilien, die nicht oder zumindest nicht zum überwiegenden Teil aus Polyester bestehen, keine oder nur unzureichende Wirksamkeit besitzen. Ein großer Teil der heutigen Textilien besteht aber aus Baumwolle oder Baumwoll-Polyester-Mischgeweben, so daß ein Bedarf nach bei fettigen Anschmutzungen auf derartigen Textilien besser wirksamen schmutzablösevermögenden Polymeren besteht.The majority of known from this extensive prior art polymers has the disadvantage that they have no or only insufficient effectiveness in textiles that do not or at least not predominantly made of polyester. However, much of today's textiles are made of cotton or cotton-polyester blend fabrics, so there is a need for soil release agents that are more effective at greasy soiling on such fabrics.

Überraschenderweise wurde nun gefunden, daß Polymerisate, die aus ganz bestimmten Monomeren erhältlich sind, eine sehr gute schmutzablösevermögende Wirkung gerade an baumwollhaltigen Textilien haben.Surprisingly, it has now been found that polymers which are obtainable from very specific monomers have a very good dirt-removing ability, especially on cotton-containing textiles.

Gegenstand der Erfindung ist daher die Verwendung eines Polymers, erhältlich aus den Monomeren Styrol, Methacrylsäure, Hydroxyethylmethacrylat und Methylmethacrylat, zur Verstärkung der Reinigungsleistung von Waschmitteln beim Waschen von Textilien.The invention therefore relates to the use of a polymer obtainable from the monomers styrene, methacrylic acid, hydroxyethyl methacrylate and methyl methacrylate, for enhancing the cleaning performance of detergents in the washing of textiles.

Wesentlich ist, daß alle 4 genannten Monomere im erfindungsgemäß verwendeten Polymer enthalten sind. Dabei sind solche Polymere bevorzugt, die aus den Anteilen Styrol 1 - 30 Mol-%, Methylmethacrylat 10 - 40 Mol-%, Methacrylsäure 20 - 60 Mol-% und Hydroxyethylmethacrylat 1 - 20 Mol-% erhältlich sind. Besonders bevorzugte Polymere sind Blockpolymere, das heißt solche, bei denen zunächst ein Monomer, insbesondere Styrol, anpolymerisiert wird, und dieses anschließend mit den übrigen Carbonsäuregruppen- beziehungsweise Carboxylatgruppen-haltigen Monomeren, gemeinsam oder nacheinander, polymerisierend umgesetzt wird. Erfindungsgemäß besonders geeignete Polymere weisen eine Molmasse nicht über 10 000 D, insbesondere von 3000 D bis 8000 D auf. Die Bestimmung des Molekulargewichts kann dabei mit Hilfe üblicher chromatographischer Methoden unter Verwendung bekannter Standards erfolgen.It is essential that all 4 mentioned monomers are included in the polymer used in the invention. In this case, preference is given to those polymers which are obtainable from the proportions of styrene 1 to 30 mol%, methyl methacrylate 10 to 40 mol%, methacrylic acid 20 to 60 mol% and hydroxyethyl methacrylate 1 to 20 mol%. Particularly preferred polymers are block polymers, ie those in which first a monomer, in particular styrene, is grafted on, and then with the others Carbonsäuregruppen- or carboxylate-containing monomers, together or in succession, is reacted polymerizing. Polymers which are particularly suitable according to the invention have a molecular weight of not more than 10,000 D, in particular from 3,000 D to 8,000 D. The determination of the molecular weight can be carried out using conventional chromatographic methods using known standards.

Die erfindungsgemäße Verwendung kann im Rahmen eines Waschprozesses derart erfolgen, daß man das Polymer einer waschmittelhaltigen Flotte separat zusetzt, oder das Polymer als Bestandteil des Waschmittels in die Flotte einbringt. Ein weiterer Gegenstand der Erfindung ist daher ein Waschmittel, das ein oben beschriebenes Polymer enthält. Die erfindungsgemäße Verwendung im Rahmen eines Wäschenachbehandlungsverfahrens kann entsprechend derart erfolgen, daß man das Polymer der Spülflotte separat zusetzt oder es als Bestandteil des Wäschenachbehandlungsmittels, insbesondere eines Weichspülers, einbringt. Bei diesem Aspekt der Erfindung kann das genannte Waschmittel ebenfalls das erfindungsgemäß zu verwendende Polymer enthalten, es kann jedoch auch frei von diesem sein.The use according to the invention can be carried out as part of a washing process in such a way that the polymer is added separately to a detergent-containing liquor, or the polymer is introduced into the liquor as a constituent of the detergent. Another object of the invention is therefore a detergent containing a polymer described above. The use according to the invention in the context of a laundry aftertreatment process can be carried out in such a way that the polymer is added separately to the rinse liquor or is it incorporated as a constituent of the laundry aftertreatment agent, in particular a fabric softener. In this aspect of the invention, said detergent may also contain, but may be free of, the polymer to be used according to the invention.

Ein weiterer Gegenstand der Erfindung ist ein Verfahren zum Waschen von Textilien, bei dem ein Waschmittel und das vorgenannte schmutzablösevermögende Polymer zum Einsatz kommen. Dieses Verfahren kann manuell oder vorzugsweise mit Hilfe einer üblichen Haushaltswaschmaschine ausgeführt werden. Dabei ist es möglich, das Waschmittel und das erfindungswesentliche Polymer gleichzeitig oder nacheinander anzuwenden. Die gleichzeitige Anwendung läßt sich besonders vorteilhaft durch den Einsatz eines Waschmittels, welches das Polymer enthält, durchführen.Another object of the invention is a method for washing textiles, in which a detergent and the aforementioned soil release polymer are used. This method can be carried out manually or preferably by means of a conventional household washing machine. It is possible to use the detergent and the polymer essential to the invention simultaneously or successively. The simultaneous application can be particularly advantageous by the use of a detergent containing the polymer perform.

Waschmittel, die das erfindungsgemäß zu verwendende Polymer enthalten, können alle üblichen sonstigen Bestandteile derartiger Mittel enthalten, die nicht in unerwünschter Weise mit diesem wechselwirken. Vorzugsweise wird das schmutzablösevermögende Polymer in Mengen von 0,1 Gew.-% bis 2 Gew.-%, insbesondere 0,4 Gew.-% bis 1 Gew.-% in Waschmittel eingearbeitet.Detergents containing the polymer to be used according to the invention may contain all the usual ingredients of such agents which do not undesirably interact with it.

Ein weiterer Aspekt der Erfindung betrifft die Verstärkung der Reinigungsleistung von Waschmitteln beim Waschen von Textilien, die aus Baumwolle bestehen oder Baumwolle enthalten.Another aspect of the invention relates to enhancing the cleaning performance of detergents in the washing of textiles made of cotton or containing cotton.

Überraschenderweise wurde gefunden, daß das erfindungsgemäß verwendete Polymer die Wirkung bestimmter anderer Wasch- und Reinigungsmittelinhaltsstoffe positiv beeinflusst und daß umgekehrt die Wirkung des erfindungsgemäß verwendeten Polymers durch bestimmte andere Waschmittelinhaltsstoffe verstärkt wird. Diese Effekte treten insbesondere bei enzymatischen Wirkstoffen, insbesondere Proteasen und Lipasen, bei wasserunlöslichen anorganischen Buildern, bei wasserlöslichen anorganischen und organischen Buildern, insbesondere auf Basis oxidierter Kohlenhydrate, bei Bleichmitteln auf Persauerstoffbasis, insbesondere bei Alkalipercarbonat, bei synthetischen Aniontensiden vom Sulfat- und Sulfonattyp und bei Vergrauungsinhibitoren, beispielsweise anderen, insbesondere anionischen Celluloseethern wie Carboxymethylcellulose, auf, weshalb der Einsatz mindestens eines der genannten weiteren Inhaltsstoffes zusammen mit dem erfindungsgemäß zu verwendenden Polymer bevorzugt ist.Surprisingly, it has been found that the polymer used according to the invention has a positive effect on the action of certain other detergent ingredients and, conversely, that the effect of the polymer used according to the invention is enhanced by certain other detergent ingredients. These effects occur in particular with enzymatic agents, in particular proteases and lipases, with water-insoluble inorganic builders, with water-soluble inorganic and organic builders, especially based on oxidized carbohydrates, with peroxygen bleaching agents, especially with alkali percarbonate, with synthetic anionic surfactants of the sulfate and sulfonate type and at Grayness inhibitors, for example other, in particular anionic cellulose ethers such as carboxymethyl cellulose, which is why the use of at least one of said further ingredient together with the polymer to be used according to the invention is preferred.

Der Alkoxylierungsgrad der Alkohole liegt dabei in der Regel zwischen 1 und 20, vorzugsweise zwischen 3 und 10. Sie können in bekannter Weise durch Umsetzung der entsprechenden Alkohole mit den entsprechenden Alkylenoxiden hergestellt werden. Geeignet sind insbesondere die Derivate der Fettalkohole, obwohl auch deren verzweigtkettige Isomere, insbesondere sogenannte Oxoalkohole, zur Herstellung verwendbarer Alkoxylate eingesetzt werden können. Brauchbar sind demgemäß die Alkoxylate, insbesondere die Ethoxylate, primärer Alkohole mit linearen, insbesondere Dodecyl-, Tetradecyl-, Hexadecyl- oder Octadecyl-Resten sowie deren Gemische. Außerdem sind entsprechende Alkoxylierungsprodukte von Alkylaminen, vicinalen Diolen und Carbonsäureamiden, die hinsichtlich des Alkylteils den genannten Alkoholen entsprechen, verwendbar. Darüberhinaus kommen die Ethylenoxid- und/oder Propylenoxid-Insertionsprodukte von Fettsäurealkylestern, wie sie gemäß dem in der internationalen Patentanmeldung WO 90/13533 angegebenen Verfahren hergestellt werden können, sowie Fettsäurepolyhydroxyamide, wie sie gemäß den Verfahren der US-amerikanischen Patentschriften US 1 985 424 , US 2 016 962 und US 2 703 798 sowie der internationalen Patentanmeldung WO 92/06984 hergestellt werden können, in Betracht. Zur Einarbeitung in die erfindungsgemäßen Mittel geeignete sogenannte Alkylpolyglykoside sind Verbindungen der allgemeinen Formel (G)n-OR12, in der R12 einen Alkyl- oder Alkenylrest mit 8 bis 22 C-Atomen, G eine Glykoseeinheit und n eine Zahl zwischen 1 und 10 bedeuten. Derartige Verbindungen und ihre Herstellung werden zum Beispiel in den europäischen Patentanmeldungen EP 92 355 , EP 301 298 , EP 357 969 und EP 362 671 oder der US-amerikanischen Patentschrift US 3 547 828 beschrieben.

Die aus derartigen glykosidisch verknüpften Monomeren bestehenden Oligomere werden außer durch die Art der in ihnen enthaltenen Zucker durch deren Anzahl, den sogenannten Oligomerisierungsgrad, charakterisiert. Der Oligomerisierungsgrad n nimmt als analytisch zu ermittelnde Größe im allgemeinen gebrochene Zahlenwerte an; er liegt bei Werten zwischen 1 und 10, bei den vorzugsweise eingesetzten Glykosiden unter einem Wert von 1,5, insbesondere zwischen 1,2 und 1,4.

The water-soluble organic builder substances include, in particular, those from the class of the polycarboxylic acids, in particular citric acid and sugar acids, and also the polymeric (poly) carboxylic acids, in particular the polycarboxylates of the international patent application obtainable by oxidation of polysaccharides WO 93/16110 , polymeric acrylic acids, methacrylic acids, Maleic acids and copolymers of these, which may also contain polymerized small amounts of polymerizable substances without carboxylic acid functionality. The molecular weight of the homopolymers of unsaturated carboxylic acids is generally between 5000 and 200,000, that of the copolymers between 2000 and 200,000, preferably 50,000 to 120,000, based on the free acid. A particularly preferred acrylic acid-maleic acid copolymer has a molecular weight of 50,000 to 100,000. Suitable, although less preferred, compounds of this class are copolymers of acrylic or methacrylic acid with vinyl ethers, such as vinylmethyl ethers, vinyl esters, ethylene, propylene and styrene, in which the acid content is at least 50% by weight. It is also possible to use as water-soluble organic builder substances terpolymers which contain two carboxylic acids and / or salts thereof as monomers and vinyl alcohol and / or a vinyl alcohol derivative or a carbohydrate as the third monomer. The first acidic monomer or its salt is derived from a monoethylenically unsaturated C 3 -C 8 -carboxylic acid and preferably from a C 3 -C 4 -monocarboxylic acid, in particular from (meth) acrylic acid. The second acidic monomer or its salt can be a derivative of a C 4 -C 8 -dicarboxylic acid, with maleic acid being particularly preferred.
