Description

Gebiet der ErfindungField of the Invention

Die Erfindung befindet sich auf dem Gebiet der geformten Waschmittel und betrifft Tabletten mit Tensiden, Buildem und Sprengmitteln, die als Avivagemittel zusätzlich Proteine oder Proteinderivate enthalten.The invention is in the field of molded detergents and relates to tablets with surfactants, Builders and disintegrants which additionally contain proteins or protein derivatives as anti-caking agents.

Stand der TechnikState of the art

Im Markt sind Waschmittel erhältlich, die die Wäsche nicht nur reinigen, sondern ihr auch einen besonderen Weichgriff verleihen. Solche Zubereitungen, die häufig als Softdetergents bezeichnet werden, enthalten als Avivagemittel in der Regel kationische Tenside vom Typ der Tetraalkylammoniumverbindungen, meist in Kombination mit Schichtsilicaten. Die genannten quartären Ammoniumverbindungen sind hinsichtlich ihrer biologischen Abbaubarkeit nicht zufriedenstellend, zudem ist bekannt, daß mit ihnen behandelte Wäsche bei sehr empfindlichen Verbrauchern Irritationen auslösen können. In Kombination mit anionischen Tensiden kommt es zudem leicht zu einer unerwünschten Salzbildung. Aus diesem Grunde besteht ein lebhaftes Interesse an Ersatzstoffen, die frei von diesen Nachteilen sind.Detergents are available on the market that not only clean the laundry, but also a special one Give soft handle. Such preparations, which are often referred to as soft detergents, usually contain cationic surfactants of the tetraalkylammonium compound type as finishing agents, mostly in combination with layered silicates. The quaternary ammonium compounds mentioned are unsatisfactory in terms of their biodegradability, and it is also known that with laundry treated with them can cause irritation to very sensitive consumers. In combination Anionic surfactants also easily lead to undesirable salt formation. Out therefore there is a keen interest in substitutes that are free from these disadvantages.

Eine Lösung bestünde im Austausch der quartären Ammoniumverbindungen gegen andere kationische Tenside vom Typ der Esterquats. Diese sind zwar hinsichtlich ihrer ökotoxikologischen Verträglich wesentlich besser zu beurteilen und besitzen sogar vielfach überlegene Avivageeigenschaften, sind unter den alkalischen Bedingungen des Waschprozesses nur eingeschränkt hydrolysebeständig und kommen damit nicht als echter Ersatzstoff in Frage.One solution would be to exchange the quaternary ammonium compounds for other cationic ones Esterquat type surfactants. These are essential with regard to their ecotoxicological compatibility are easier to assess and even have superior finishing properties the alkaline conditions of the washing process are only resistant to hydrolysis and come thus not in question as a real substitute.

Demzufolge hat die Aufgabe der vorliegenden Erfindung darin bestanden, neue geformte Waschmittel, vorzugsweise in Form von Tabletten zur Verfügung zu stellen, die hinsichtlich ihrer ökotoxikologischen Verträglichkeit nicht länger zu beanstanden und unter Waschbedingungen leicht löslich sind, eine hinreichende chemische Beständigkeit zeigen sowie insbesondere der Wäsche einen ausgezeichneten Weichgriff verleihen. Accordingly, the object of the present invention was to provide new shaped detergents, preferably in the form of tablets available with regard to their ecotoxicological Tolerance no longer objectionable and easily soluble under washing conditions, a sufficient one show chemical resistance and excellent, especially in laundry Give soft handle.

Beschreibung der ErfindungDescription of the invention

Gegenstand der Erfindung sind Waschmittettabtetten, enthaltend

  • (a) anionische, nichtionische und/oder amphotere Tenside,
  • (b) nicht-enzymatische Proteine und/oder deren Derivate,
  • (c) Zeolithe und
  • (d) Sprengmittel.
    • The invention relates to detergent tablets containing
  • (a) anionic, nonionic and / or amphoteric surfactants,
  • (b) non-enzymatic proteins and / or their derivatives,
  • (c) zeolites and
  • (d) explosives.

    • Überraschenderweise wurde gefunden, daß die erfindungsgemäßen Waschmitteltabletten die eingangs genannten Anforderungen in vorzüglicher Weise erfüllen. Die nicht-enzymatischen Proteine und Proteinderivate stellen ideale Ersatzstoffe für kationische Tenside dar, da sie eine vergleichbare Avivage bewirken, dabei jedoch auch unter alkalischen Bedingungen chemisch stabil sind und weder aus ökologischer noch toxikologischer Sicht Anlaß zur Beanstandung bieten. Insbesondere in Kombination mit Zeolithen als Buildern wird ein besonders vorteilhafter Avivageeffekt beobachtet, der durch den Zusatz von Schichtsilicaten und/oder den Einsatz eines Tensidsystems auf Basis von Alkylbenzolsulfonaten und Alkylsulfaten noch weiter verbessert werden kann. Vorzugsweise sind die Waschmittel frei von kationischen Tensiden.Surprisingly, it was found that the detergent tablets of the invention meet the requirements mentioned in an excellent manner. The non-enzymatic proteins and protein derivatives are ideal substitutes for cationic surfactants, as they have a comparable finish cause, but are also chemically stable under alkaline conditions and neither from ecological still give cause for complaint from a toxicological point of view. Especially in combination with Zeolites as builders are observed to have a particularly advantageous softening effect, which is due to the addition of layered silicates and / or the use of a surfactant system based on alkylbenzenesulfonates and alkyl sulfates can be further improved. The detergents are preferably free of cationic surfactants.

    Als alkoxylierte Fettsäureniedrigalkylester kommen Tenside der Formel (V) in Betracht, R6CO-(OCH2CHR7)mOR8   (V) in der R6CO für einen linearen oder verzweigten, gesättigten und/oder ungesättigten Acylrest mit 6 bis 22 Kohlenstoffatomen, R7 für Wasserstoff oder Methyl, R8 für lineare oder verzweigte Alkylreste mit 1 bis 4 Kohlenstoffatomen und m für Zahlen von 1 bis 20 steht.

    Alkyl- und Alkenyloligoglykoside, die ebenfalls bevorzugte nichtionische Tenside darstellen, folgen üblicherweise der Formel (VI), R9O-[G]p   (VI) in der R9 für einen Alkyl- und/oder Alkenylrest mit 4 bis 22 Kohlenstoffatomen, G für einen Zuckerrest mit 5 oder 6 Kohlenstoffatomen und p für Zahlen von 1 bis 10 steht. Sie können nach den einschlägigen Verfahren der präparativen organischen Chemie erhalten werden. Stellvertretend für das umfangreiche Schrifttum sei hier auf die Schriften EP-A1 0 301 298 und WO 90/03977 verwiesen. Die Alkylund/oder Alkenyloligoglykoside können sich von Aldosen bzw. Ketosen mit 5 oder 6 Kohlenstoffatomen, vorzugsweise der Glucose ableiten. Die bevorzugten Alkyl- und/oder Alkenyloligoglykoside sind somit Alkyl- und/oder Alkenyloligoglucoside. Die Indexzahl p in der allgemeinen Formel (VI) gibt den Oligomerisierungsgrad (DP), d. h. die Verteilung von Mono- und Oligoglykosiden an und steht für eine Zahl zwischen 1 und 10. Während p in einer gegebenen Verbindung stets ganzzahlig sein muß und hier vor allem die Werte p = 1 bis 6 annehmen kann, ist der Wert p für ein bestimmtes Alkyloligoglykosid eine analytisch ermittelte rechnerische Größe, die meistens eine gebrochene Zahl darstellt. Vorzugsweise werden Alkyl- und/oder Alkenyloligoglykoside mit einem mittleren Oligomerisierungsgrad p von 1,1 bis 3,0 eingesetzt. Aus anwendungstechnischer Sicht sind solche Alkyl- und/oder Alkenyloligoglykoside bevorzugt, deren Oligomerisierungsgrad kleiner als 1,7 ist und insbesondere zwischen 1,2 und 1,4 liegt. Der Alkyl- bzw. Alkenylrest R9 kann sich von primären Alkoholen mit 4 bis 11, vorzugsweise 8 bis 10 Kohlenstoffatomen ableiten. Typische Beispiele sind Butanol, Capronalkohol, Caprylalkohol, Caprinalkohol und Undecylalkohol sowie deren technische Mischungen, wie sie beispielsweise bei der Hydrierung von technischen Fettsäuremethylestem oder im Verlauf der Hydrierung von Aldehyden aus der Roelen'schen Oxosynthese erhalten werden. Bevorzugt sind Alkyloligoglucoside der Kettenlänge C8-C10 (DP = 1 bis 3), die als Vorlauf bei der destillativen Auftrennung von technischem C8-C18-Kokosfettalkohol anfallen und mit einem Anteil von weniger als 6 Gew.-% C12-Alkohol verunreinigt sein können sowie Alkyloligoglucoside auf Basis technischer C9/11-Oxoalkohole (DP = 1 bis 3). Der Alkyl- bzw. Alkenylrest R9 kann sich ferner auch von primären Alkoholen mit 12 bis 22, vorzugsweise 12 bis 14 Kohlenstoffatomen ableiten. Typische Beispiele sind Laurylalkohol, Myristylalkohol, Cetylalkohol, Palmoleylalkohol, Stearylalkohol, Isostearylalkohol, Oleylalkohol, Elaidylalkohol, Petroselinylalkohol, Arachylalkohof, Gadoleylalkohol, Behenylalkohol, Erucylalkohol, Brassidylalkohol sowie deren technische Gemische, die wie oben beschrieben erhalten werden können. Bevorzugt sind Alkyloligoglucoside auf Basis von gehärtetem C12/14-Kokosalkohol mit einem DP von 1 bis 3. Alkyl and alkenyl oligoglycosides, which are also preferred nonionic surfactants, usually follow the formula (VI), R 9 O- [G] p (VI) in which R 9 is an alkyl and / or alkenyl radical having 4 to 22 carbon atoms, G is a sugar radical having 5 or 6 carbon atoms and p is a number from 1 to 10. They can be obtained according to the relevant procedures in preparative organic chemistry. Representative of the extensive literature, reference is made here to the documents EP-A1 0 301 298 and WO 90/03977 . The alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligo glucosides . The index number p in the general formula (VI) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While p in a given compound must always be an integer, especially here can assume the values p = 1 to 6, the value p for a specific alkyl oligoglycoside is an analytically determined arithmetic parameter, which usually represents a fractional number. Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, preference is given to those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and is in particular between 1.2 and 1.4. The alkyl or alkenyl radical R 9 can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capronic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis. Alkyl oligoglucosides of chain length C 8 -C 10 (DP = 1 to 3) are preferred, which are obtained as a preliminary step in the separation of technical C 8 -C 18 coconut fatty alcohol by distillation and with a proportion of less than 6% by weight of C 12 - Alcohol can be contaminated and alkyl oligoglucosides based on technical C 9/11 oxo alcohols (DP = 1 to 3). The alkyl or alkenyl radical R 9 can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and their technical mixtures, as described above, which can be obtained as described above. Alkyl oligoglucosides based on hardened C 12/14 coconut alcohol with a DP of 1 to 3 are preferred.

    Typische Beispiele für amphotere bzw. zwitterionische Tenside sind Alkylbetaine, Alkylamidobetaine, Aminopropionate, Aminoglycinate, Imidazoliniumbetaine und Sulfobetaine. Bei den genannten Tensiden handelt es sich ausschließlich um bekannte Verbindungen. Hinsichtlich Struktur und Herstellung dieser Stoffe sei auf einschlägige Übersichtsarbeiten beispielsweise J.Falbe (ed.), "Surfactants in Consumer Products", Springer Verlag, Berlin, 1987, S. 34-124 oder J.Falbe (ed.), "Katalysatoren, Tenside und Mineralöladditive", Thieme Verlag, Stuttgart, 1978, S. 123-217 verwiesen. Die Waschmittel können die Tenside in Mengen von 1 bis 50, vorzugsweise 5 bis 25 und insbesondere 10 bis 20 Gew.-% - bezogen auf die Waschmittel - enthalten.Typical examples of amphoteric or zwitterionic surfactants are alkyl betaines, alkyl amido betaines, aminopropionates, aminoglycinates, imidazolinium betaines and sulfobetaines. The surfactants mentioned are exclusively known compounds. With regard to the structure and manufacture of these substances, reference is made to relevant reviews, for example J.Falbe (ed.), "Surfactants in Consumer Products", Springer Verlag, Berlin, 1987, pp. 34-124 or J.Falbe (ed.), "Catalysts, Tenside und Mineralöladditive ", Thieme Verlag, Stuttgart, 1978, pp. 123-217 . The detergents can contain the surfactants in amounts of 1 to 50, preferably 5 to 25 and in particular 10 to 20% by weight, based on the detergents.

    Nicht-enzymatische Proteine und deren DerivateNon-enzymatic proteins and their derivatives

    Nicht-enzymatische Proteine und deren Derivate (Komponente b), bei denen es sich vorzugsweise um Proteinhydrolysate und/oder Proteinfettsäurekondensate handelt, sind bekannte Substanzen, die beispielsweise in Hautpflegmittel eingesetzt werden [vgl. Seifen-Fette-Öle-Wachse, 108, 117 (1982)]. Der Zusatz "nicht-enzymatisch" wurde gewählt, um die Stoffe von typischen Waschmittelenzymen zu unterscheiden, die im Sinne der Erfindung keine Anwendung finden. Typische Beispiele für nicht-enzymatische Proteine, die in den erfindungsgemässen Mitteln eingesetzt werden können, sind Keratin, Elastin, Kollagen, Weizenproteine, Milchproteine, Eiweißproteine, Seidenproteine, Mandelproteine, Sojaproteine und andere Getreideproteine, sowie Proteine aus Tierhäuten. Proteinhydrolysate stellen Abbauprodukte dieser tierischen oder pflanzlichen Proteine dar, die durch saure, alkalische und/oder enzymatische Hydrolyse gespalten werden und danach ein durchschnittliches Molekulargewicht im Bereich von 600 bis 4000, vorzugsweise 2000 bis 3500 aufweisen. Obschon Proteinhydrolysate in Ermangelung eines hydrophoben Restes keine Tenside im klassischen Sinne darstellen, finden sie wegen ihrer dispergierenden Eigenschaften vielfach Verwendung zur Formulierung oberflächenaktiver Mittel. Übersichten zu Herstellung und Verwendung von Proteinhydrolysaten sind beispielsweise von G.Schuster und A.Domsch in Seifen Öle Fette Wachse, 108, 177 (1982) bzw. Cosm.Toil. 99, 63 (1984), von H.W.Steisslinger in Parf. Kosm. 72, 556 (1991) und F.Aurich et al. in Tens.Surf.Det. 29, 389 (1992) erschienen. Durch Umsetzung der genannten Proteinhydrolysate mit Fettsäuren, welche in der Regel 6 bis 22 und vorzugsweise 12 bis 18 Kohlenstoffatome im Acylrest enthalten, werden Proteinfettsäurekondensate gewonnen. Die Kondensate werden gewöhnlich in Form ihrer Alkali-, Erdalkali-, Ammonium, Alkylammonium- oder Alkanolammoniumsalze eingesetzt. Typische Beispiele sind die Kondensationsprodukte von Weizen- oder Sojaproteinhydrolysaten mit Capronsäure, Caprylsäure, 2-Ethylhexansäure, Caprinsäure, Laurinsäure, Isotridecansäure, Myristinsäure, Palmitinsäure, Palmoleinsäure, Stearinsäure, Isostearinsäure, Ölsäure, Elaidinsäure, Petroselinsäure, Linolsäure, Linolensäure, Elaeostearinsäure, Arachinsäure, Gadoleinsäure, Behensäure und Erucasäure sowie deren technische Mischungen. Die erfindungsgemäßen Mittel können die Proteine bzw. Proteinderivate in Mengen von 0,1 bis 10, vorzugsweise 1 bis 8 und insbesondere 3 bis 5 Gew.-% - bezogen auf die Mittel - enthalten.Non-enzymatic proteins and their derivatives (component b), which are preferably protein hydrolyzates and / or protein fatty acid condensates, are known substances that are used, for example, in skin care products [cf. Soap-Fat-Oil-Waxes, 108 , 117 (1982)]. The addition "non-enzymatic" was chosen to distinguish the substances from typical detergent enzymes, which are not used in the sense of the invention. Typical examples of non-enzymatic proteins that can be used in the agents according to the invention are keratin, elastin, collagen, wheat proteins, milk proteins, protein proteins, silk proteins, almond proteins, soy proteins and other cereal proteins, and proteins from animal skins. Protein hydrolysates are degradation products of these animal or vegetable proteins, which are cleaved by acidic, alkaline and / or enzymatic hydrolysis and then have an average molecular weight in the range from 600 to 4000, preferably 2000 to 3500. Although protein hydrolyzates, in the absence of a hydrophobic residue, are not surfactants in the classical sense, they are widely used for the formulation of surface-active agents because of their dispersing properties. Overviews of the production and use of protein hydrolyzates are, for example, from G. Schuster and A. Domsch in Seifen Öle Fette Wachsen , 108, 177 (1982) and Cosm.Toil. 99, 63 (1984), by HW Steisslinger in Parf. Kosm. 72, 556 (1991) and F. Aurich et al. in Tens.Surf.Det. 29, 389 (1992) . Protein fatty acid condensates are obtained by reacting the protein hydrolysates mentioned with fatty acids which generally contain 6 to 22 and preferably 12 to 18 carbon atoms in the acyl radical. The condensates are usually used in the form of their alkali, alkaline earth, ammonium, alkylammonium or alkanolammonium salts. Typical examples are the condensation products of wheat or soy protein hydrolyzates with caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselachic acid, linoleic acid, linoleic acid , Behenic acid and erucic acid and their technical mixtures. The agents according to the invention can contain the proteins or protein derivatives in amounts of 0.1 to 10, preferably 1 to 8 and in particular 3 to 5% by weight, based on the agents.

    Zeolithezeolites

    Als Builder (Komponente c) können die erfindungsgemäßen Waschmittel Zeolithe enthalten. Der als Waschmittelbuilder häufig eingesetzte feinkristalline, synthetische und gebundenes Wasser enthaltende Zeolith ist vorzugsweise Zeolith A und/oder P. Als Zeolith P wird beispielsweise Zeolith MAP(R) (Handelsprodukt der Firma Crosfield) besonders bevorzugt. Geeignet sind jedoch auch Zeolith X sowie Mischungen aus A, X und/oder P wie auch Y. Von besonderem Interesse ist auch ein cokristallisiertes Natrium/Kalium-Aluminiumsilikat aus Zeolith A und Zeolith X, weiches als VEGOBOND AX® (Handelsprodukt der Firma Condea Augusta S.p.A.) im Handel erhältlich ist. Der Zeolith kann als sprühgetrocknetes Pulver oder auch als ungetrocknete, von ihrer Herstellung noch feuchte, stabilisierte Suspension zum Einsatz kommen. Für den Fall, daß der Zeolith als Suspension eingesetzt wird, kann diese geringe Zusätze an nichtionischen Tensiden als Stabilisatoren enthalten, beispielsweise 1 bis 3 Gew.-%, bezogen auf Zeolith, an ethoxylierten C12-C18-Fettalkoholen mit 2 bis 5 Ethylenoxidgruppen, C12-C14-Fettalkoholen mit 4 bis 5 Ethylenoxidgruppen oder ethoxylierten Isotridecanolen. Geeignete Zeolithe weisen eine mittlere Teilchengröße von weniger als 10 µm (Volumenverteilung; Meßmethode: Coulter Counter) auf und enthalten vorzugsweise 18 bis 22 Gew.-%, insbesondere 20 bis 22 Gew.-% an gebundenem Wasser. Die Zeolithe sind in den Endzubereitungen vorzugsweise in Mengen von 10 bis 60, insbesondere 20 bis 40 Gew.-% - bezogen auf die Mittel - enthalten. The detergents according to the invention may contain zeolites as builders (component c). The fine crystalline, synthetic and bound water-containing zeolite frequently used as a detergent builder is preferably zeolite A and / or P. As zeolite P, for example, zeolite MAP (R) (commercial product from Crosfield) is particularly preferred. However, zeolite X and mixtures of A, X and / or P and Y are also suitable. Of particular interest is also a cocrystallized sodium / potassium aluminum silicate made of zeolite A and zeolite X, which is soft as VEGOBOND AX® (commercial product from Condea Augusta SpA) is commercially available. The zeolite can be used as a spray-dried powder or as an undried stabilized suspension that is still moist from its production. In the event that the zeolite is used as a suspension, it can contain small additions of nonionic surfactants as stabilizers, for example 1 to 3% by weight, based on zeolite, of ethoxylated C 12 -C 18 fatty alcohols with 2 to 5 ethylene oxide groups , C 12 -C 14 fatty alcohols with 4 to 5 ethylene oxide groups or ethoxylated isotridecanols. Suitable zeolites have an average particle size of less than 10 μm (volume distribution; measurement method: Coulter Counter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight, of bound water. The zeolites are contained in the final preparations preferably in amounts of 10 to 60, in particular 20 to 40,% by weight, based on the composition.

    Sprengmittelexplosives

    Unter dem Begriff Sprengmittel (Komponente d) sind Stoffe zu verstehen, die den Formkörpem zugegeben werden, um deren Zerfall beim Inkontaktbringen mit Wasser zu beschleunigen. Übersichten hierzu finden sich z.B. in J.Pharm.Sci. 61 (1972) oder Römpp Chemilexikon, 9. Auflage, Band 6, S. 4440. Die Sprengmittel können im Formkörper makroskopisch betrachtet homogen verteilt vorliegen, mikroskopisch gesehen bilden sie jedoch herstellungsbedingt Zonen erhöhter Konzentration. Zu den bevorzugten Sprengmitteln gehören Polysaccharide, wie z.B. natürliche Stärke und deren Derivate (Carboxymethylstärke, Stärkeglycolate in Form ihrer Alkalisalze, Agar Agar, Guar Gum, Pektine usw.), Cellulosen und deren Derivate (Carboxymethylcellulose, mikrokristalline Cellulose), Polyvinylpyrrolidon, Kollidon, Alginsäure und deren Alkalisalze, amorphe oder auch teilweise kristalline Schichtsilicate (Bentonite), Polyurethane, Polyethylenglycole sowie gaserzeugende Systeme. Weitere Sprengmittel, die im Sinne der Erfindung zugegen sein können, sind beispielsweise den Druckschriften WO 98/40462 (Rettenmeyer), WO 98/55583 und WO 98/55590 (Unilever) und WO 98/40463, DE 19709991 und DE 19710254 (Henkel) zu entnehmen. Auf die Lehre dieser Schriften wird ausdrücklich Bezug genommen.
    Die Formkörper können die Sprengmittel in Mengen von 0,1 bis 25, vorzugsweise 1 bis 20 und insbesondere 5 bis 15 Gew.-% - bezogen auf die Formkörper enthalten.    The term disintegrant (component d) is to be understood as meaning substances which are added to the shaped bodies in order to accelerate their disintegration when they come into contact with water. Overviews can be found, for example, in J.Pharm.Sci. 61 (1972) or Römpp Chemilexikon, 9th edition, volume 6, p. 4440. The disintegrants can be macroscopically distributed homogeneously in the molded body, but microscopically they form zones of increased concentration due to the manufacturing process. The preferred disintegrants include polysaccharides such as natural starch and its derivatives (carboxymethyl starch, starch glycolates in the form of their alkali salts, agar agar, guar gum, pectins etc.), celluloses and their derivatives (carboxymethyl cellulose, microcrystalline cellulose), polyvinylpyrrolidone, collidone, alginic acid and their alkali salts, amorphous or also partially crystalline layered silicates (bentonites), polyurethanes, polyethylene glycols and gas-generating systems. Further disintegrants which may be present in the sense of the invention are, for example, the publications WO 98/40462 (Rettenmeyer), WO 98/55583 and WO 98/55590 (Unilever) and WO 98/40463, DE 19709991 and DE 19710254 (Henkel) refer to. Reference is expressly made to the teaching of these writings.
    The moldings can contain the disintegrants in amounts of 0.1 to 25, preferably 1 to 20 and in particular 5 to 15% by weight, based on the moldings.

    Hilfs- und ZusatzstoffeAuxiliaries and additives

    Weitere bevorzugte Inhaltsstoffe der erfindungsgemäßen Waschmittel sind zusätzliche anorganische und organische Buildersubstanzen, wobei als anorganische Buildersubstanzen hauptsächlich kristalline Schichtsilikate und amorphe Silikate mit Buildereigenschaften sowie - wo zulässig - auch Phosphate wie Tripolyphosphate zum Einsatz kommen. Die Menge an Co-Builder ist dabei auf die bevorzugten Mengen an Zeolithen anzurechnen.Further preferred ingredients of the detergents according to the invention are additional inorganic and organic builder substances, the inorganic builder substances being mainly crystalline Layered silicates and amorphous silicates with builder properties and - where permitted - also phosphates how tripolyphosphates are used. The amount of co-builder is preferred Count amounts of zeolites.

    Geeignete Substitute bzw. Teilsubstitute für Phosphate und Zeolithe sind kristalline, schichtförmige Natriumsilikate der allgemeinen Formel NaMSixO2x+1·yH2O, wobei M Natrium oder Wasserstoff bedeutet, x eine Zahl von 1,9 bis 4 und y eine Zahl von 0 bis 20 ist und bevorzugte Werte für x 2, 3 oder 4 sind. Derartige kristalline Schichtsilikate werden beispielsweise in der europäischen Patentanmeldung EP 0164514 A1 beschrieben. Bevorzugte kristalline Schichtsilikate der angegebenen Formel sind solche, in denen M für Natrium steht und x die Werte 2 oder 3 annimmt. Insbesondere sind sowohl β- als auch δ-Natriumdisilikate Na2Si2O5·yH2O bevorzugt, wobei β-Natriumdisilikat beispielsweise nach dem Verfahren erhalten werden kann, das in der internationalen Patentanmeldung WO 91/08171 beschrieben ist. Weitere geeignete Schichtsilicate sind beispielsweise aus den Patentanmeldungen DE 2334899 A1, EP 0026529 A1 und DE 3526405 A1 bekannt. Ihre Verwendbarkeit ist nicht auf eine spezielle Zusammensetzung bzw. Strukturformel beschränkt. Bevorzugt sind hier jedoch Smectite, insbesondere Bentonite. Geeignete Schichtsilicate, die zur Gruppe der mit Wasser quellfähigen Smectite zählen, sind z.B. solche der allgemeinen Formeln (OH)4Si8-yAly(MgxAl4-x)O20   Montmorrilonit (OH)4Si8-yAly(Mg6-zLiz)O20   Hectorit (OH)4Si8-yAly(Mg6-z Alz)O20   Saponit mit x = 0 bis 4, y = 0 bis 2, z = 0 bis 6. Zusätzlich kann in das Kristallgitter der Schichtsilicate gemäß den vorstehenden Formeln geringe Mengen an Eisen eingebaut sein. Ferner können die Schichtsilicate aufgrund ihrer ionenaustauschenden Eigenschaften Wasserstoff-, Alkali-, Erdalkaliionen, insbesondere Na+ und Ca2+ enthalten. Die Hydratwassermenge liegt meist im Bereich von 8 bis 20 Gew.-% und ist vom Quellzustand bzw. von der Art der Bearbeitung abhängig. Brauchbare Schichtsilicate sind beispielsweise aus US 3,966,629, US 4,062,647, EP 0026529 A1 und EP 0028432 A1 bekannt. Vorzugsweise werden Schichtsilicate verwendet, die aufgrund einer Alkalibehandlung weitgehend frei von Calciumionen und stark färbenden Eisenionen sind.Suitable substitutes or partial substitutes for phosphates and zeolites are crystalline, layered sodium silicates of the general formula NaMSi x O 2x + 1 .yH 2 O, where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20 and preferred values for x are 2, 3 or 4. Such crystalline layered silicates are described, for example, in European patent application EP 0164514 A1 . Preferred crystalline layered silicates of the formula given are those in which M represents sodium and x assumes the values 2 or 3. In particular, both β- and δ-sodium disilicate Na 2 Si 2 O 5 .yH 2 O are preferred, wherein β-sodium disilicate can be obtained, for example, by the method described in international patent application WO 91/08171 . Further suitable layered silicates are known, for example, from patent applications DE 2334899 A1, EP 0026529 A1 and DE 3526405 A1 . Their usability is not limited to a special composition or structural formula. However, smectites, in particular bentonites, are preferred here. Suitable layered silicates, which belong to the group of water-swellable smectites, are, for example, those of the general formulas (OH) 4 Si 8-y Al y (Mg x Al 4-x ) O 20 montmorrilonite (OH) 4 Si 8-y Al y (Mg 6-z Li z ) O 20 hectorite (OH) 4 Si 8-y Al y (Mg 6-z Al z ) O 20 saponite with x = 0 to 4, y = 0 to 2, z = 0 to 6. In addition, small amounts of iron can be incorporated into the crystal lattice of the layered silicates according to the above formulas. Furthermore, due to their ion-exchanging properties, the layered silicates can contain hydrogen, alkali, alkaline earth ions, in particular Na + and Ca 2+ . The amount of water of hydration is usually in the range from 8 to 20% by weight and depends on the swelling condition or the type of processing. Useful layer silicates are known, for example, from US 3,966,629, US 4,062,647, EP 0026529 A1 and EP 0028432 A1 . Layered silicates are preferably used which are largely free of calcium ions and strongly coloring iron ions due to an alkali treatment.

    Zu den bevorzugten Buildersubstanzen gehören auch amorphe Natriumsilikate mit einem Modul Na2O : SiO2 von 1 : 2 bis 1 : 3,3, vorzugsweise von 1 : 2 bis 1 : 2,8 und insbesondere von 1 : 2 bis 1 : 2,6, welche löseverzögert sind und Sekundärwascheigenschaften aufweisen. Die Löseverzögerung gegenüber herkömmlichen amorphen Natriumsilikaten kann dabei auf verschiedene Weise, beispielsweise durch Oberflächenbehandlung, Compoundierung, KompaktierungNerdichtung oder durch Übertrocknung hervorgerufen worden sein. Im Rahmen dieser Erfindung wird unter dem Begriff "amorph" auch "röntgenamorph" verstanden. Dies heißt, daß die Silikate bei Röntgenbeugungsexperimenten keine scharfen Röntgenreflexe liefern, wie sie für kristalline Substanzen typisch sind, sondern allenfalls ein oder mehrere Maxima der gestreuten Röntgenstrahlung, die eine Breite von mehreren Gradeinheiten des Beugungswinkels aufweisen. Es kann jedoch sehr wohl sogar zu besonders guten Buildereigenschaften führen, wenn die Silikatpartikel bei Elektronenbeugungsexperimenten verwaschene oder sogar scharfe Beugungsmaxima liefem. Dies ist so zu interpretieren, daß die Produkte mikrokristalline Bereiche der Größe 10 bis einige Hundert nm aufweisen, wobei Werte bis max. 50 nm und insbesondere bis max. 20 nm bevorzugt sind. Derartige sogenannte röntgenamorphe Silikate, welche ebenfalls eine Löseverzögerung gegenüber den herkömmlichen Wassergläsern aufweisen, werden beispielsweise in der deutschen Patentanmeldung DE 4400024 A1 beschrieben. Insbesondere bevorzugt sind verdichtete/kompaktierte amorphe Silikate, compoundierte amorphe Silikate und übertrocknete röntgenamorphe Silikate. The preferred builder substances also include amorphous sodium silicates with a modulus Na 2 O: SiO 2 from 1: 2 to 1: 3.3, preferably from 1: 2 to 1: 2.8 and in particular from 1: 2 to 1: 2, 6, which are delayed release and have secondary washing properties. The delay in dissolution compared to conventional amorphous sodium silicates can be caused in various ways, for example by surface treatment, compounding, compacting / sealing or by overdrying. In the context of this invention, the term “amorphous” is also understood to mean “X-ray amorphous”. This means that the silicates in X-ray diffraction experiments do not provide sharp X-ray reflections, as are typical for crystalline substances, but at most one or more maxima of the scattered X-rays, which have a width of several degree units of the diffraction angle. However, it can very well lead to particularly good builder properties if the silicate particles run washed-out or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline areas of size 10 to a few hundred nm, values up to max. 50 nm and in particular up to max. 20 nm are preferred. Such so-called X-ray amorphous silicates, which also have a delay in dissolution compared to conventional water glasses, are described, for example, in German patent application DE 4400024 A1 . Compacted / compacted amorphous silicates, compounded amorphous silicates and over-dried X-ray amorphous silicates are particularly preferred.

    Selbstverständlich ist auch ein Einsatz der allgemein bekannten Phosphate als Buildersubstanzen möglich, sofern ein derartiger Einsatz nicht aus ökologischen Gründen vermieden werden sollte. Geeignet sind insbesondere die Natriumsalze der Orthophosphate, der Pyrophosphate und insbesondere der Tripolyphosphate. Ihr Gehalt beträgt im allgemeinen nicht mehr als 25 Gew.-%, vorzugsweise nicht mehr als 20 Gew.-%, jeweils bezogen auf das fertige Mittel. In einigen Fällen hat es sich gezeigt, daß insbesondere Tripolyphosphate schon in geringen Mengen bis maximal 10 Gew.-%. bezogen auf das fertige Mittel, in Kombination mit anderen Buildersubstanzen zu einer synergistischen Verbesserung des Sekundärwaschvermögens führen.It goes without saying that the generally known phosphates are also used as builder substances possible if such use should not be avoided for ecological reasons. Suitable are in particular the sodium salts of orthophosphates, pyrophosphates and in particular the tripolyphosphate. Their content is generally not more than 25% by weight, preferably not more than 20 wt .-%, each based on the finished agent. In some cases it has been shown that in particular tripolyphosphates in small amounts up to a maximum of 10% by weight. based on the finished agents, in combination with other builder substances to a synergistic improvement of secondary washing power.

    Brauchbare organische Gerüstsubstanzen sind beispielsweise die in Form ihrer Natriumsalze einsetzbaren Polycarbonsäuren, wie Citronensäure, Adipinsäure, Bemsteinsäure, Glutarsäure, Weinsäure, 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, Bemsteinsäure, Glutarsäure, Weinsäure, Zuckersäuren und Mischungen aus diesen. 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.Useful organic builders are, for example, those that can be used in the form of their sodium salts Polycarboxylic acids, such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, Sugar acids, aminocarboxylic acids, nitrilotriacetic acid (NTA), provided such use ecological reasons are not objectionable, as well as 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 of these. 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 value of Detergents or cleaning agents. In particular, citric acid, succinic acid, glutaric acid, Adipic acid, gluconic acid and any mixtures of these.

    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 500 000. 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 2 000 bis 30 000. Ein bevorzugtes Dextrin ist in der britischen Patentanmeldung GB 9419091 A1 beschrieben. 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. Derartige oxidierte Dextrine und Verfahren ihrer Herstellung sind beispielsweise aus den europäischen Patentanmeldungen EP 0232202 A1, EP 0427349 A1, EP 0472042 A1 und EP 0542496 A1 sowie den internationalen Patentanmeldungen WO 92/18542, WO 93/08251, WO 93/16110, WO 94/28030, WO 95/07303, WO 95/12619 und WO 95/20608 bekannt. Ebenfalls geeignet ist ein oxidiertes Oligosaccharid gemäß der deutschen Patentanmeldung DE 19600018 A1. Ein an C6 des Saccharidrings oxidiertes Produkt kann besonders vorteilhaft sein.Other 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. They are preferably hydrolysis products with average molecular weights in the range from 400 to 500,000. 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 customary measure for the reducing effect of a polysaccharide compared to dextrose, which has a DE of 100. Both maltodextrins with a DE between 3 and 20 and dry glucose syrups with a DE between 20 and 37 as well as so-called yellow dextrins and white dextrins with higher molar masses in the range from 2,000 to 30,000 can be used. A preferred dextrin is described in British patent application GB 9419091 A1 , 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. Such oxidized dextrins and processes for their preparation are known, for example, from European patent applications EP 0232202 A1, EP 0427349 A1, EP 0472042 A1 and EP 0542496 A1 and international patent applications WO 92/18542, WO 93/08251, WO 93/16110, WO 94 / 28030, WO 95/07303, WO 95/12619 and WO 95/20608 are known. An oxidized oligosaccharide according to German patent application DE 19600018 A1 is also suitable . A product oxidized at C 6 of the saccharide ring can be particularly advantageous.

    Weitere geeignete Cobuilder sind Oxydisuccinate und andere Derivate von Disuccinaten, vorzugsweise Ethylendiamindisuccinat. Besonders bevorzugt sind in diesem Zusammenhang auch Glycerindisuccinate und Glycerintrisuccinate, wie sie beispielsweise in den US-amerikanischen Patentschriften US 4,524,009, US 4,639,325, in der europäischen Patentanmeldung EP 0150930 A1 und der japanischen Patentanmeldung JP 93/339896 beschrieben werden. Geeignete Einsatzmengen liegen in zeolithhaltigen und/oder silikathaltigen Formulierungen bei 3 bis 15 Gew.-%.Other suitable cobuilders are oxydisuccinates and other derivatives of disuccinates, preferably ethylenediamine disuccinate. Also particularly preferred in this context are glycerol disuccinates and glycerol trisuccinates , such as are described, for example, in US Pat. Nos. 4,524,009, 4,639,325, in European patent application EP 0150930 A1 and in Japanese patent application JP 93/339896 . Suitable amounts used in formulations containing zeolite and / or silicate are from 3 to 15% by weight.

    Weitere brauchbare organische Cobuilder sind beispielsweise acetylierte Hydroxycarbonsäuren bzw. deren Salze, welche gegebenenfalls auch in Lactonform vorliegen können und welche mindestens 4 Kohlenstoffatome und mindestens eine Hydroxygruppe sowie maximal zwei Säuregruppen enthalten. Derartige Cobuilder werden beispielsweise in der internationalen Patentanmeldung WO 95/20029 beschrieben.Other useful organic cobuilders are, for example, acetylated hydroxycarboxylic acids or their salts, which may also be in lactone form and which contain at least 4 carbon atoms and at least one hydroxyl group and a maximum of two acid groups. Such cobuilders are described, for example, in international patent application WO 95/20029 .

    Geeignete polymere Polycarboxylate sind beispielsweise die Natriumsalze der Polyacrylsäure oder der Polymethacrylsäure, beispielsweise solche mit einer relativen Molekülmasse von 800 bis 150 000 (auf Säure bezogen und jeweils gemessen gegen Polystyrolsulfonsäure). Geeignete copolymere Polycarboxylate sind insbesondere solche der Acrylsäure mit Methacrylsäure und der Acrylsäure oder Methacrylsäure mit Maleinsäure. 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 5 000 bis 200 000, vorzugsweise 10 000 bis 120 000 und insbesondere 50 000 bis 100 000 (jeweils gemessen gegen Polystyrolsulfonsäure). Die (co-)polymeren Polycarboxylate können entweder als Pulver oder als wäßrige Lösung eingesetzt werden, wobei 20 bis 55 Gew.-%ige wäßrige Lösungen bevorzugt sind. Granulare Polymere werden zumeist nachträglich zu einem oder mehreren Basisgranulaten zugemischt. Insbesondere bevorzugt sind auch biologisch abbaubare Polymere aus mehr als zwei verschiedenen Monomereinheiten, beispielsweise solche, die gemäß der DE 4300772 A1 als Monomere Salze der Acrylsäure und der Maleinsäure sowie Vinylalkohol bzw. Vinylalkohol-Derivate oder gemäß der DE 4221381 C2 als Monomere Salze der Acrylsäure und der 2-Alkylallylsulfonsäure sowie Zucker-Derivate enthalten. Weitere bevorzugte Copolymere sind solche, die in den deutschen Patentanmeldungen DE 4303320 A1 und DE 4417734 A1 beschrieben werden und als Monomere vorzugsweise Acrolein und Acrylsäure/Acrylsäuresalze bzw. Acrolein und Vinylacetat aufweisen. Ebenso sind als weitere bevorzugte Buildersubstanzen polymere Aminodicarbonsäuren, deren Salze oder deren Vorläufersubstanzen zu nennen. Besonders bevorzugt sind Polyasparaginsäuren bzw. deren Salze und Derivate. Suitable polymeric polycarboxylates are, for example, the sodium salts of polyacrylic acid or polymethacrylic acid, for example those with a relative molecular weight of 800 to 150,000 (based on acid and measured in each case against polystyrene sulfonic acid). Suitable copolymeric polycarboxylates are, 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 5,000 to 200,000, preferably 10,000 to 120,000 and in particular 50,000 to 100,000 (measured in each case against polystyrene sulfonic acid). The (co) polymeric polycarboxylates can be used either as a powder or as an aqueous solution, with 20 to 55% by weight aqueous solutions being preferred. Granular polymers are usually subsequently mixed into one or more basic granules. Also particularly preferred are biodegradable polymers composed of more than two different monomer units, for example those which, according to DE 4300772 A1, are salts of acrylic acid and maleic acid, as well as vinyl alcohol or vinyl alcohol derivatives, or, according to DE 4221381 C2, are monomer salts of acrylic acid and the 2-alkylallylsulfonic acid and sugar derivatives. Further preferred copolymers are those which are described in German patent applications DE 4303320 A1 and DE 4417734 A1 and which preferably contain acrolein and acrylic acid / acrylic acid salts or acrolein and vinyl acetate as monomers. Also to be mentioned as further preferred builder substances are polymeric aminodicarboxylic acids, their salts or their precursor substances. Polyaspartic acids or their salts and derivatives are particularly preferred.

    Als Enzyme kommen insbesondere solche aus der Klasse der Hydrolasen, wie der Proteasen, Esterasen, Lipasen bzw. lipolytisch wirkenden Enzyme, Amylasen, Cellulasen bzw. andere Glykosylhydrolasen und Gemische der genannten Enzyme in Frage. Alle diese Hydrolasen tragen in der Wäsche zur Entfernung von Verfleckungen, wie protein-, fett- oder stärkehaltigen Verfleckungen, und Vergrauungen bei. Cellulasen und andere Glykosylhydrolasen können durch das Entfernen von Pilling und Mikrofibrillen zur Farberhaltung und zur Erhöhung der Weichheit des Textils beitragen. Zur Bleiche bzw. zur Hemmung der Farbübertragung können auch Oxidoreduktasen eingesetzt werden. Besonders gut geeignet sind aus Bakterienstämmen oder Pilzen, wie Bacillus subtilis, Bacillus licheniformis, Streptomyces griseus und Humicola insolens gewonnene enzymatische Wirkstoffe. Vorzugsweise werden Proteasen vom Subtilisin-Typ und insbesondere Proteasen, die aus Bacillus lentus gewonnen werden, eingesetzt. Dabei sind Enzymmischungen, beispielsweise aus Protease und Amylase oder Protease und Lipase bzw. lipolytisch wirkenden Enzymen oder Protease und Cellulase oder aus Cellulase und Lipase bzw. lipolytisch wirkenden Enzymen oder aus Protease, Amylase und Lipase bzw. lipolytisch wirkenden Enzymen oder Protease, Lipase bzw. lipolytisch wirkenden Enzymen und Cellulase, insbesondere jedoch Protease- und/oder Lipase-haltige Mischungen bzw. Mischungen mit lipolytisch wirkenden Enzymen von besonderem Interesse. Beispiele für derartige lipolytisch wirkende Enzyme sind die bekannten Cutinasen. Auch Peroxidasen oder Oxidasen haben sich in einigen Fällen als geeignet erwiesen. Zu den geeigneten Amylasen zählen insbesondere α-Amylasen, Iso-Amylasen, Pullulanasen und Pektinasen. Als Cellulasen werden vorzugsweise Cellobiohydrolasen, Endoglucanasen und β-Glucosidasen, die auch Cellobiasen genannt werden, bzw. Mischungen aus diesen eingesetzt. Da sich die verschiedenen Cellulase-Typen durch ihre CMCase- und Avicelase-Aktivitäten unterscheiden, können durch gezielte Mischungen der Cellulasen die gewünschten Aktivitäten eingestellt werden. Enzymes in particular include those from the class of hydrolases, such as proteases, esterases, Lipases or lipolytic enzymes, amylases, cellulases or other glycosyl hydrolases and mixtures of the enzymes mentioned. All of these hydrolases carry in the Laundry for removing stains such as stains containing protein, fat or starch, and Graying at. Cellulases and other glycosyl hydrolases can be removed by removing pilling and microfibrils help maintain color and increase the softness of the textile. To bleach or to inhibit color transfer, oxidoreductases can also be used. Especially are particularly suitable from bacterial strains or fungi, such as Bacillus subtilis, Bacillus licheniformis, Streptomyces griseus and Humicola insolens enzymatic active substances obtained. Preferably be Proteases of the subtilisin type and in particular proteases obtained from Bacillus lentus, used. Enzyme mixtures, for example of protease and amylase or protease and lipase or lipolytic enzymes or protease and cellulase or from cellulase and lipase or lipolytic enzymes or from protease, amylase and lipase or lipolytic acting enzymes or protease, lipase or lipolytically acting enzymes and cellulase, in particular, however, protease- and / or lipase-containing mixtures or mixtures with lipolytic acting enzymes of particular interest. Examples of such lipolytic enzymes are the well-known cutinases. Peroxidases or oxidases have also been found to be suitable in some cases proved. Suitable amylases include in particular α-amylases, iso-amylases, pullulanases and pectinases. Cellobiohydrolases, endoglucanases are preferred as cellulases and β-glucosidases, which are also called cellobiases, or mixtures thereof. Since the different cellulase types differ in their CMCase and avicelase activities, the desired activities can be set by targeted mixtures of the cellulases.

    Die Enzyme können an Trägerstoffen adsorbiert und/oder in Hüllsubstanzen eingebettet sein, um sie gegen vorzeitige Zersetzung zu schützen. Der Anteil der Enzyme, Enzymmischungen oder Enzymgranulate kann beispielsweise etwa 0,1 bis 5 Gew.-%, vorzugsweise 0,1 bis etwa 2 Gew.-% betragen.The enzymes can be adsorbed on carriers and / or embedded in coating substances around them protect against premature decomposition. The proportion of enzymes, enzyme mixtures or enzyme granules can be, for example, about 0.1 to 5% by weight, preferably 0.1 to about 2% by weight.

    Zusätzlich zu den mono- und polyfunktionellen Alkoholen können die Mittel weitere Enzymstabilisatoren enthalten. Beispielsweise können 0,5 bis 1 Gew.-% Natriumformiat eingesetzt werden. Möglich ist auch der Einsatz von Proteasen, die mit löslichen Calciumsalzen und einem Calciumgehalt von vorzugsweise etwa 1,2 Gew.-%, bezogen auf das Enzym, stabilisiert sind. Außer Calciumsalzen dienen auch Magnesiumsalze als Stabilisatoren. Besonders vorteilhaft ist jedoch der Einsatz von Borverbindungen, beispielsweise von Borsäure, Boroxid, Borax und anderen Alkalimetallboraten wie den Salzen der Orthoborsäure (H3BO3), der Metaborsäure (HBO2) und der Pyroborsäure (Tetraborsäure H2B4O7). Vergrauungsinhibitoren haben die Aufgabe, den von der Faser abgelösten Schmutz in der Flotte suspendiert zu halten und so das Wiederaufziehen des Schmutzes zu verhindern. Hierzu sind wasserlösliche Kolloide meist organischer Natur geeignet, beispielsweise die wasserlöslichen Salze polymerer Carbonsäuren, Leim, Gelatine, Salze von Ethercarbonsäuren oder Ethersulfonsäuren der Stärke oder der Cellulose oder Salze von sauren Schwefelsäureestern der Cellulose oder der Stärke. Auch wasserlösliche, saure Gruppen enthaltende Polyamide sind für diesen Zweck geeignet. Weiterhin lassen sich lösliche Stärkepräparate und andere als die obengenannten Stärkeprodukte verwenden, z.B. abgebaute Stärke, Aldehydstärken usw.. Auch Polyvinylpyrrolidon ist brauchbar. Bevorzugt werden jedoch Celluloseether, wie Carboxymethylcellulose (Na-Salz), Methylcellulose, Hydroxyalkylcellulose und Mischether, wie Methylhydroxyethylcellulose, Methylhydroxypropylcellulose, Methylcarboxymethylcellulose und deren Gemische, sowie Polyvinylpyrrolidon beispielsweise in Mengen von 0,1 bis 5 Gew.-%, bezogen auf die Mittel, eingesetzt.In addition to the mono- and polyfunctional alcohols, the agents can contain further enzyme stabilizers . For example, 0.5 to 1% by weight sodium formate can be used. It is also possible to use proteases which are stabilized with soluble calcium salts and a calcium content of preferably about 1.2% by weight, based on the enzyme. In addition to calcium salts, magnesium salts also serve as stabilizers. However, the use of boron compounds, for example boric acid, boron oxide, borax and other alkali metal borates such as the salts of orthoboric acid (H 3 BO 3 ), metaboric acid (HBO 2 ) and pyrobic acid (tetraboric acid H 2 B 4 O 7 ), is particularly advantageous. Graying inhibitors have the task of keeping the dirt detached from the fiber suspended in the liquor and thus preventing the dirt from being re-absorbed. Water-soluble colloids of mostly organic nature are suitable for this, for example the water-soluble salts of polymeric carboxylic acids, glue, gelatin, salts of ether carboxylic acids or ether sulfonic acids of starch or cellulose or salts of acidic sulfuric acid esters of cellulose or starch. Water-soluble polyamides containing acidic groups are also suitable for this purpose. Soluble starch preparations and starch products other than those mentioned above can also be used, for example degraded starch, aldehyde starches, etc. Polyvinylpyrrolidone can also be used. However, cellulose ethers, such as carboxymethyl cellulose (sodium salt), methyl cellulose, hydroxyalkyl cellulose and mixed ethers, such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof, and polyvinylpyrrolidone, for example in amounts of 0.1 to 5% by weight, based on the composition, are preferred. used.

    Die Mittel können als optische Aufheller Derivate der Diaminostilbendisulfonsäure bzw. deren Alkalimetallsalze enthalten. Geeignet sind z.B. Salze der 4,4'-Bis(2-anilino-4-morpholino-1,3,5-triazinyl-6-amino)stilben-2,2'-disulfonsäure oder gleichartig aufgebaute Verbindungen, die anstelle der Morpholino-Gruppe eine Diethanolaminogruppe, eine Methylaminogruppe, eine Anilinogruppe oder eine 2-Methoxyethylaminogruppe tragen.

Auch Gemische der vorgenannten Aufheller können verwendet werden. Einheitlich weiße Granulate werden erhalten, wenn die Mittel außer den üblichen Aufhellern in üblichen Mengen, beispielsweise zwischen 0,1 und 0,5 Gew.-%, vorzugsweise zwischen 0,1 und 0,3 Gew.-%, auch geringe Mengen, beispielsweise 10-6 bis 10-3 Gew.-%, vorzugsweise um 10-5 Gew.-%, eines blauen Farbstoffs enthalten. Ein besonders bevorzugter Farbstoff ist Tinolux® (Handelsprodukt der Ciba-Geigy). The agents can contain derivatives of diaminostilbenedisulfonic acid or their alkali metal salts as optical brighteners . Suitable are, for example, salts of 4,4'-bis (2-anilino-4-morpholino-1,3,5-triazinyl-6-amino) stilbene-2,2'-disulfonic acid or compounds of similar structure which instead of the morpholino- Group carry a diethanolamino group, a methylamino group, anilino group or a 2-methoxyethylamino group. Brighteners of the substituted diphenylstyryl type may also be present, for example the alkali salts of 4,4'-bis (2-sulfostyryl) diphenyl, 4,4'-bis (4-chloro-3-sulfostyryl) diphenyl, or 4- (4-chlorostyryl) -4 '- (2-sulfostyryl) -diphenyis. Mixtures of the aforementioned brighteners can also be used. Uniformly white granules are obtained if, in addition to the usual brighteners, the agents are also present in customary amounts, for example between 0.1 and 0.5% by weight, preferably between 0.1 and 0.3% by weight, even in small amounts, for example Contain 10 -6 to 10 -3 wt .-%, preferably by 10 -5 wt .-%, of a blue dye. A particularly preferred dye is Tinolux® (commercial product from Ciba-Geigy).

    Als Entschäumer können wachsartige Verbindungen eingesetzt werden. Als "wachsartig" werden solche Verbindungen verstanden, die einen Schmelzpunkt bei Atmosphärendruck über 25 °C (Raumtemperatur), vorzugsweise über 50 °C und insbesondere über 70 °C aufweisen. Die wachsartigen Entschäumersubstanzen sind in Wasser praktisch nicht löslich, d.h. bei 20 °C weisen sie in 100 g Wasser eine Löslichkeit unter 0,1 Gew.-% auf. Prinzipiell können alle aus dem Stand der Technik bekannten wachsartigen Entschäumersubstanzen enthalten sein. Geeignete wachsartige Verbindungen sind beispielsweise Bisamide, Fettalkohole, Fettsäuren, Carbonsäureester von ein- und mehrwertigen Alkoholen sowie Paraffinwachse oder Mischungen derselben. Alternativ können natürlich auch die für diesen Zweck bekannten Silikonverbindungen eingesetzt werden.Wax-like compounds can be used as defoamers. Such are called "waxy" Understood compounds that have a melting point at atmospheric pressure above 25 ° C (room temperature), preferably have above 50 ° C and in particular above 70 ° C. The waxy defoamer substances are practically insoluble in water, i.e. at 20 ° C in 100 g of water solubility below 0.1% by weight. In principle, all known from the prior art wax-like defoamer substances can be included. Suitable waxy compounds are, for example Bisamides, fatty alcohols, fatty acids, carboxylic acid esters of mono- and polyhydric alcohols as well as paraffin waxes or mixtures thereof. Alternatively, of course, you can also use them Purpose known silicone compounds are used.

    Geeignete Paraffinwachse stellen im allgemeinen ein komplexes Stoffgemisch ohne scharfen Schmelzpunkt dar. Zur Charakterisierung bestimmt man üblicherweise seinen Schmelzbereich durch Differential-Thermo-Analyse (DTA), wie in "The Analyst" 87 (1962), 420, beschrieben, und/oder seinen Erstarrungspunkt. Darunter versteht man die Temperatur, bei der das Paraffin durch langsames Abkühlen aus dem flüssigen in den festen Zustand übergeht. Dabei sind bei Raumtemperatur vollständig flüssige Paraffine, das heißt solche mit einem Erstarrungspunkt unter 25 °C, erfindungsgemäß nicht brauchbar. Eingesetzt werden können beispielsweise die aus EP 0309931 A1 bekannten Paraffinwachsgemische aus beispielsweise 26 Gew.-% bis 49 Gew.-% mikrokristallinem Paraffinwachs mit einem Erstarrungspunkt von 62 °C bis 90 °C, 20 Gew.-% bis 49 Gew.-% Hartparaffin mit einem Erstarrungspunkt von 42 °C bis 56 °C und 2 Gew.-% bis 25 Gew.-% Weichparaffin mit einem Erstarrungspunkt von 35 °C bis 40 °C. Vorzugsweise werden Paraffine bzw. Paraffingemische verwendet, die im Bereich von 30 °C bis 90 °C erstarren. Dabei ist zu beachten, daß auch bei Raumtemperatur fest erscheinende Paraffinwachsgemische unterschiedliche Anteile an flüssigem Paraffin enthalten können. Suitable paraffin waxes generally represent a complex mixture of substances without a sharp melting point. For characterization, one usually determines its melting range by differential thermal analysis (DTA), as described in "The Analyst" 87 (1962), 420 , and / or its solidification point , This is the temperature at which the paraffin changes from the liquid to the solid state by slow cooling. Paraffins which are completely liquid at room temperature, that is to say those having a solidification point below 25 ° C., cannot be used according to the invention. For example, the paraffin wax mixtures known from EP 0309931 A1 of, for example, 26% by weight to 49% by weight of microcrystalline paraffin wax with a solidification point of 62 ° C. to 90 ° C., 20% by weight to 49% by weight hard paraffin can be used with a solidification point from 42 ° C to 56 ° C and 2% by weight to 25% by weight soft paraffin with a solidification point from 35 ° C to 40 ° C. Paraffins or paraffin mixtures which solidify in the range from 30 ° C. to 90 ° C. are preferably used. It should be noted that even paraffin wax mixtures that appear solid at room temperature can contain different proportions of liquid paraffin.

    Bei den erfindungsgemäß brauchbaren Paraffinwachsen liegt dieser Flüssiganteil so niedrig wie möglich und fehlt vorzugsweise ganz. So weisen besonders bevorzugte Paraffinwachsgemische bei 30 °C einen Flüssiganteil von unter 10 Gew.-%, insbesondere von 2 Gew.-% bis 5 Gew.-%, bei 40 °C einen Flüssiganteil von unter 30 Gew.-%, vorzugsweise von 5 Gew.-% bis 25 Gew.-% und insbesondere von 5 Gew.-% bis 15 Gew.-%, bei 60 °C einen Flüssiganteil von 30 Gew.-% bis 60 Gew.-%, insbesondere von 40 Gew.-% bis 55 Gew.-%, bei 80 °C einen Flüssiganteil von 80 Gew.-% bis 100 Gew.-%, und bei 90 °C einen Flüssiganteil von 100 Gew.-% auf. Die Temperatur, bei der ein Flüssiganteil von 100 Gew.-% des Paraffinwachses erreicht wird, liegt bei besonders bevorzugten Paraffinwachsgemischen noch unter 85 °C, insbesondere bei 75 °C bis 82 °C. Bei den Paraffinwachsen kann es sich um Petrolatum, mikrokristalline Wachse bzw. hydrierte oder partiell hydrierte Paraffinwachse handeln.In the paraffin waxes which can be used according to the invention, this liquid fraction is as low as possible and preferably completely missing. For example, particularly preferred paraffin wax mixtures at 30 ° C a liquid content of less than 10% by weight, in particular from 2% by weight to 5% by weight, at 40 ° C. Liquid content of less than 30% by weight, preferably from 5% by weight to 25% by weight and in particular from 5% by weight to 15% by weight, at 60 ° C. a liquid fraction of 30% by weight to 60% by weight, in particular from 40% by weight to 55% by weight, at 80 ° C. a liquid fraction from 80% by weight to 100% by weight, and at 90 ° C a liquid content of 100 wt .-%. The temperature at which a liquid content of 100% by weight of the paraffin wax is reached, is still in the case of particularly preferred paraffin wax mixtures below 85 ° C, especially at 75 ° C to 82 ° C. The paraffin waxes can be petrolatum, act microcrystalline waxes or hydrogenated or partially hydrogenated paraffin waxes.

Glycerol monostearate, glycerol monooleate, glycerol monopalmitate, glycerol monobehenate and glycerol distearate are examples of this. Examples of suitable natural esters as defoamers are beeswax, which mainly consists of the esters CH 3 (CH 2 ) 24 COO (CH 2 ) 27 CH 3 and CH 3 (CH 2 ) 26 COO (CH 2 ) 25 CH 3 , and carnauba wax , which is a mixture of camamaic acid alkyl esters, often in combination with small amounts of free carnauba acid, other long-chain acids, high-molecular alcohols and hydrocarbons.

    Geeignete Carbonsäuren als weitere Entschäumerverbindung sind insbesondere Behensäure, Stearinsäure, Ölsäure, Palmitinsäure, Myristinsäure und Laurinsäure sowie deren Gemische, wie sie aus natürlichen Fetten bzw. gegebenenfalls gehärteten Ölen, wie Talg oder hydriertem Palmöl, erhältlich sind. Bevorzugt sind gesättigte Fettsäuren mit 12 bis 22, insbesondere 18 bis 22 C-Atomen.Suitable carboxylic acids as a further defoamer compound are in particular behenic acid, stearic acid, Oleic acid, palmitic acid, myristic acid and lauric acid and their mixtures, as made up natural fats or optionally hardened oils, such as tallow or hydrogenated palm oil are. Saturated fatty acids with 12 to 22, in particular 18 to 22, carbon atoms are preferred.

    Geeignete Fettalkohole als weitere Entschäumerverbindung sind die hydrierten Produkte der beschriebenen Fettsäuren.
    Weiterhin können zusätzlich Dialkylether als Entschäumer enthalten sein. Die Ether können asymmetrisch oder aber symmetrisch aufgebaut sein, d.h. zwei gleiche oder verschiedene Alkylketten, vorzugsweise mit 8 bis 18 Kohlenstoffatomen enthalten. Typische Beispiele sind Di-n-octylether, Di-ioctylether und Di-n-stearylether, insbesondere geeignet sind Dialkylether, die einen Schmelzpunkt über 25 °C, insbesondere über 40 °C aufweisen.    Suitable fatty alcohols as a further defoamer compound are the hydrogenated products of the fatty acids described.
    Dialkyl ethers may also be present as defoamers. The ethers can be constructed asymmetrically or symmetrically, ie contain two identical or different alkyl chains, preferably with 8 to 18 carbon atoms. Typical examples are di-n-octyl ether, di-ioctyl ether and di-n-stearyl ether; dialkyl ethers which have a melting point above 25 ° C., in particular above 40 ° C., are particularly suitable.

    Weitere geeignete Entschäumerverbindungen sind Fettketone, die nach den einschlägigen Methoden der präparativen organischen Chemie erhalten werden können. Zu ihrer Herstellung geht man beispielsweise von Carbonsäuremagnesiumsalzen aus, die bei Temperaturen oberhalb von 300 °C unter Abspaltung von Kohlendioxid und Wasser pyrolysiert werden, beispielsweise gemäß der deutschen Offenlegungsschrift DE 2553900 OS. Geeignete Fettketone sind solche, die durch Pyrolyse der Magnesiumsalze von Laurinsäure, Myristinsäure, Palmitinsäure, Palmitoleinsäure, Stearinsäure, Ölsäure, Elaidinsäure, Petroselinsäure, Arachinsäure, Gadoleinsäure, Behensäure oder Erucasäure hergestellt werden.Other suitable defoamer compounds are fatty ketones, which can be obtained by the relevant methods of preparative organic chemistry. For their preparation, one starts from, for example, carboxylic acid magnesium salts which are pyrolyzed at temperatures above 300 ° C. with the elimination of carbon dioxide and water, for example in accordance with German published patent application DE 2553900 OS. Suitable fat ketones are those which are prepared by pyrolysis of the magnesium salts of lauric acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, elaidic acid, petroselinic acid, arachic acid, gadoleic acid, behenic acid or erucic acid.

    Weitere geeignete Entschäumer sind Fettsäurepolyethylenglykolester, die vorzugsweise durch basisch homogen katalysierte Anlagerung von Ethylenoxid an Fettsäuren erhalten werden. Insbesondere erfolgt die Anlagerung von Ethylenoxid an die Fettsäuren in Gegenwart von Alkanolaminen als Katalysatoren. Der Einsatz von Alkanolaminen, speziell Triethanolamin, führt zu einer äußerst selektiven Ethoxylierung der Fettsäuren, insbesondere dann, wenn es darum geht, niedrig ethoxylierte Verbindungen herzustellen. Innerhalb der Gruppe der Fettsäurepolyethylenglykolester werden solche bevorzugt, die einen Schmelzpunkt über 25 °C, insbesondere über 40 °C aufweisen.Other suitable defoamers are fatty acid polyethylene glycol esters, which are preferably obtained by base-homogeneously catalyzed addition of ethylene oxide to fatty acids. In particular, the addition of ethylene oxide to the fatty acids takes place in the presence of alkanolamines as catalysts. The use of alkanolamines, especially triethanolamine, leads to an extremely selective ethoxylation of the fatty acids, especially when it comes to producing low-ethoxylated compounds. Within the group of fatty acid polyethylene glycol esters, preference is given to those which have a melting point above 25 ° C., in particular above 40 ° C.

    Innerhalb der Gruppe der wachsartigen Entschäumer werden besonders bevorzugt die beschriebenen Paraffinwachse alleine als wachsartige Entschäumer eingesetzt oder in Mischung mit einem der anderen wachsartigen Entschäumer, wobei der Anteil der Paraffinwachse in der Mischung vorzugsweise über 50 Gew.-% - bezogen auf wachsartige Entschäumermischung - ausmacht. Die Paraffinwachse können bei Bedarf auf Träger aufgebracht sein. Als Trägermaterial sind alle bekannten anorganischen und/oder organischen Trägermaterialien geeignet. Beispiele für typische anorganische Trägermaterialien sind Alkalicarbonate, Alumosilikate, wasserlösliche Schichtsilikate, Alkalisilikate, Alkalisulfate, beispielsweise Natriumsulfat, und Alkaliphosphate. Bei den Alkalisilikaten handelt es sich vorzugsweise um eine Verbindung mit einem Molverhältnis Alkalioxid zu SiO2 von 1 : 1,5 bis 1 : 3,5. Die Verwendung derartiger Silikate resultiert in besonders guten Komeigenschaften, insbesondere hoher Abriebsstabilität und dennoch hoher Auflösungsgeschwindigkeit in Wasser. Zu den als Trägermaterial bezeichneten Alumosilikaten gehören insbesondere die Zeolithe, beispielsweise Zeolith NaA und NaX. Zu den als wasserlöslichen Schichtsilikaten bezeichneten Verbindungen gehören beispielsweise amorphes oder kristallines Wasserglas. Weiterhin können Silikate Verwendung finden, welche unter der Bezeichnung Aerosil® oder Sipemat® im Handel sind. Als organische Trägermaterialien kommen zum Beispiel filmbildende Polymere, beispielsweise Polyvinylalkohole, Polyvinylpyrrolidone, Poly(meth)acrylate, Polycarboxylate, Cellulosederivate und Stärke in Frage. Brauchbare Celluloseether sind insbesondere Alkalicarboxymethylcellulose, Methylcellulose, Ethylcellulose, Hydroxyethylcellulose und sogenannte Cellulosemischether, wie zum Beispiel Methylhydroxyethylcellulose und Methylhydroxypropylcellulose, sowie deren Mischungen. Besonders geeignete Mischungen sind aus Natrium-Carboxymethylcellulose und Methylcellulose zusammengesetzt, wobei die Carboxymethylcellulose üblicherweise einen Substitutionsgrad von 0,5 bis 0,8 Carboxymethylgruppen pro Anhydroglukoseeinheit und die Methylcellulose einen Substitutionsgrad von 1,2 bis 2 Methylgruppen pro Anhydroglukoseeinheit aufweist. Die Gemische enthalten vorzugsweise Alkalicarboxymethylcellulose und nichtionischen Celluloseether in Gewichtsverhältnissen von 80 : 20 bis 40 : 60, insbesondere von 75 : 25 bis 50 : 50. Als Träger ist auch native Stärke geeignet, die aus Amylose und Amylopectin aufgebaut ist. Als native Stärke wird Stärke bezeichnet, wie sie als Extrakt aus natürlichen Quellen zugänglich ist, beispielsweise aus Reis, Kartoffeln, Mais und Weizen. Native Stärke ist ein handelsübliches Produkt und damit leicht zugänglich. Als Trägermaterialien können einzeln oder mehrere der vorstehend genannten Verbindungen eingesetzt werden, insbesondere ausgewählt aus der Gruppe der Alkalicarbonate, Alkalisulfate, Alkaliphosphate, Zeolithe, wasserlösliche Schichtsilikate, Alkalisilikate, Polycarboxylate, Celluloseether, Polyacrylat/Polymethacrylat und Stärke. Besonders geeignet sind Mischungen von Alkalicarbonaten, insbesondere Natriumcarbonat, Alkalisilikaten, insbesondere Natriumsilikat, Alkalisulfaten, insbesondere Natriumsulfat und Zeolithen.Within the group of wax-like defoamers, the paraffin waxes described are particularly preferably used alone as wax-like defoamers or in a mixture with one of the other wax-like defoamers, the proportion of paraffin waxes in the mixture preferably making up more than 50% by weight, based on the wax-like defoamer mixture. The paraffin waxes can be applied to carriers if necessary. All known inorganic and / or organic carrier materials are suitable as carrier materials. Examples of typical inorganic carrier materials are alkali carbonates, aluminosilicates, water-soluble layered silicates, alkali silicates, alkali sulfates, for example sodium sulfate, and alkali phosphates. The alkali silicates are preferably a compound with a molar ratio of alkali oxide to SiO 2 of 1: 1.5 to 1: 3.5. The use of such silicates results in particularly good grain properties, in particular high abrasion stability and nevertheless a high rate of dissolution in water. The aluminosilicates referred to as carrier material include, in particular, the zeolites, for example zeolite NaA and NaX. The compounds referred to as water-soluble layered silicates include, for example, amorphous or crystalline water glass. Silicates which are commercially available under the names Aerosil® or Sipemat® can also be used. Examples of suitable organic carrier materials are film-forming polymers, for example polyvinyl alcohols, polyvinyl pyrrolidones, poly (meth) acrylates, polycarboxylates, cellulose derivatives and starch. Usable cellulose ethers are, in particular, alkali carboxymethyl cellulose, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose and so-called cellulose mixed ethers, such as, for example, methyl hydroxyethyl cellulose and methyl hydroxypropyl cellulose, and mixtures thereof. Particularly suitable mixtures are composed of sodium carboxymethyl cellulose and methyl cellulose, the carboxymethyl cellulose usually having a degree of substitution of 0.5 to 0.8 carboxymethyl groups per anhydroglucose unit and the methyl cellulose having a degree of substitution of 1.2 to 2 methyl groups per anhydroglucose unit. The mixtures preferably contain alkali carboxymethyl cellulose and nonionic cellulose ethers in weight ratios from 80:20 to 40:60, in particular from 75:25 to 50:50. Also suitable as a carrier is native starch which is composed of amylose and amylopectin. Starch is referred to as native starch, as it is available as an extract from natural sources, for example from rice, potatoes, corn and wheat. Native starch is a commercially available product and is therefore easily accessible. Carrier materials which can be used individually or more than one of the abovementioned compounds, in particular selected from the group of alkali metal carbonates, alkali metal sulfates, alkali metal phosphates, zeolites, water-soluble sheet silicates, alkali metal silicates, polycarboxylates, cellulose ethers, polyacrylate / polymethacrylate and starch. Mixtures of alkali carbonates, in particular sodium carbonate, alkali silicates, in particular sodium silicate, alkali sulfates, in particular sodium sulfate and zeolites are particularly suitable.

    Geeignete Silikone sind übliche Organopolysiloxane, die einen Gehalt an feinteiliger Kieselsäure, die wiederum auch silaniert sein kann, aufweisen können. Derartige Organopolysiloxane sind beispielsweise in der europäischen Patentanmeldung EP 0496510 A1 beschrieben. Besonders bevorzugt sind Polydiorganosiloxane, die aus dem Stand der Technik bekannt sind. Es können aber auch über Siloxan vemetzte Verbindungen eingesetzt werden, wie sie dem Fachmann unter der Bezeichnung Silikonharze bekannt sind. In der Regel enthalten die Polydiorganosiloxane feinteilige Kieselsäure, die auch silaniert sein kann. Insbesondere geeignet sind kieselsäurehaltige Dimethylpolysiloxane. Vorteilhafterweise haben die Polydiorganosiloxane eine Viskosität nach Brookfield bei 25 °C im Bereich von 5 000 mPas bis 30 000 mPas, insbesondere von 15 000 bis 25 000 mPas. Die Silikone sind vorzugsweise auf Trägermaterialien aufgebracht. Geeignete Trägermaterialien sind bereits im Zusammenhang mit den Paraffinen beschrieben worden. Die Trägermaterialien sind in der Regel in Mengen von 40 bis 90 Gew.-%, vorzugsweise in Mengen von 45 bis 75 Gew.-% - bezogen auf Entschäumer - enthalten.Suitable silicones are conventional organopolysiloxanes, which can have a content of finely divided silica, which in turn can also be silanized. Such organopolysiloxanes are described, for example, in European patent application EP 0496510 A1 . Polydiorganosiloxanes which are known from the prior art are particularly preferred. However, compounds crosslinked via siloxane can also be used, as are known to the person skilled in the art under the name silicone resins. As a rule, the polydiorganosiloxanes contain finely divided silica, which can also be silanized. Silica-containing dimethylpolysiloxanes are particularly suitable. The polydiorganosiloxanes advantageously have a Brookfield viscosity at 25 ° C. in the range from 5,000 mPas to 30,000 mPas, in particular from 15,000 to 25,000 mPas. The silicones are preferably applied to carrier materials. Suitable carrier materials have already been described in connection with the paraffins. The carrier materials are generally present in amounts of 40 to 90% by weight, preferably in amounts of 45 to 75% by weight, based on defoamers.

    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 Ethem 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.As perfume oils or fragrances, individual fragrance compounds, e.g. the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. Fragrance compounds of the ester type are e.g. Benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, Linalyl acetate, dimethylbenzylcarbinylacetate, phenylethyl acetate, linalylbenzoate, Benzyl formate, ethyl methylphenyl glycinate, allyl cyclohexyl propionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether, the aldehydes e.g. the linear alkanals with 8-18 C atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, Lilial and bourgeonal, to the ketones e.g. the Jonone, α-isomethylionon and methylcedryl ketone, to the alcohols anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol, The hydrocarbons mainly include the terpenes such as limonene and pinene. Prefers however, mixtures of different odoriferous substances are used, which together make an appealing Generate fragrance. Such perfume oils can also contain natural fragrance mixtures, as they are accessible from plant sources, e.g. Pine, citrus, jasmine, patchouly, rose or Ylang-ylang oil. Also suitable are muscatel, sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, Cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil as well as orange blossom oil, neroliol, orange peel oil and sandalwood oil.

    Die Duftstoffe können direkt in die erfindungsgemäßen Mittel eingearbeitet werden, es kann aber auch vorteilhaft sein, die Duftstoffe auf Träger aufzubringen, welche 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. Falls gewünscht können die Endzubereitungen noch anorganische Salze als Füll- bzw. Stellmittel enthalten, wie beispielsweise Natriumsulfat, welches vorzugsweise in Mengen von 0 bis 10, insbesondere 1 bis 5 Gew.-% - bezogen auf Mittel - enthalten ist.The fragrances can be incorporated directly into the agents according to the invention, but it can also be advantageous to apply the fragrances to carriers which increase the adhesion of the perfume to the laundry and ensure a long-lasting fragrance of the textiles due to a slower fragrance release. Cyclodextrins, for example, have proven useful as such carrier materials, and the cyclodextrin-perfume complexes can additionally be coated with further auxiliaries. If desired, the final preparations can also contain inorganic salts as fillers or fillers, such as sodium sulfate, which is preferably present in amounts of 0 to 10, in particular 1 to 5% by weight, based on the composition.

    Herstellung der WaschmitteltablettenManufacture of detergent tablets

    Die Herstellung der Formkörper erfolgt in der Regel durch Tablettierung bzw. Preßagglomerierung. Die erhaltenen teilchenförmigen Preßagglomerate können entweder direkt als Waschmittel eingesetzt oder zuvor nach üblichen Methoden nachbehandelt und/oder aufbereitet werden. Zu den üblichen Nachbehandlungen zählen beispielsweise Abpuderungen mit feinteiligen Inhaltsstoffen von Wasch- oder Reinigungsmitteln, wodurch das Schüttgewicht im allgemeinen weiter erhöht wird. Eine bevorzugte Nachbehandlung stellt jedoch auch die Verfahrensweise gemäß den deutschen Patentanmeldungen DE 19524287 A1 und DE 19547457 A1 dar, wobei staubförmige oder zumindest feinteilige inhaltsstoffe (die sogenannten Feinanteile) an die erfindungsgemäß hergestellten teilchenförmigen Verfahrensendprodukte, welche als Kem dienen, angeklebt werden und somit Mittel entstehen, welche diese sogenannten Feinanteile als Außenhülle aufweisen. Vorteilhafterweise geschieht dies wiederum durch eine Schmelzagglomeration. Zur Schmelzagglomerierung der Feinanteile an wird ausdrücklich auf die Offenbarung in den deutschen Patentanmeldungen DE 19524287 A1 und DE 19547457 A1 verwiesen. In der bevorzugten Ausführungsform der Erfindung liegen die festen Waschmittel in Tablettenform vor, wobei diese Tabletten insbesondere aus lager- und transporttechnischen Gründen vorzugsweise abgerundete Ecken und Kanten aufweisen. Die Grundfläche dieser Tabletten kann beispielsweise kreisförmig oder rechteckig sein. Mehrschichtentabletten, insbesondere Tabletten mit 2 oder 3 Schichten, welche auch farblich verschieden sein können, sind vor allem bevorzugt. Blau-weiße oder grün-weiße oder blau-grün-weiße Tabletten sind dabei besonders bevorzugt. Die Tabletten können dabei auch gepreßte und ungepreßte Anteile enthalten. Formkörper mit besonders vorteilhafter Auflösegeschwindigkeit werden erhalten, wenn die granularen Bestandteile vor dem Verpressen einen Anteil an Teilchen, die einen Durchmesser außerhalb des Bereiches von 0,02 bis 6 mm besitzen, von weniger als 20, vorzugsweise weniger als 10 Gew.-% aufweisen. Bevorzugt ist eine Teilchengrößenverteilung im Bereich von 0,05 bis 2,0 und besonders bevorzugt von 0,2 bis 1,0 mm. The moldings are generally produced by tableting or press agglomeration. The particulate press agglomerates obtained can either be used directly as detergents or previously treated and / or prepared by conventional methods. The usual aftertreatments include, for example, powdering with finely divided ingredients from washing or cleaning agents, which generally further increases the bulk density. However, a preferred aftertreatment is also the procedure according to German patent applications DE 19524287 A1 and DE 19547457 A1 , in which dusty or at least finely divided constituents (the so-called fine fractions) are adhered to the particulate end products of the process, which serve as cores, and thus give rise to means , which have these so-called fines as an outer shell. In turn, this advantageously takes place by melting agglomeration. For melt agglomeration of the fine fractions, reference is expressly made to the disclosure in German patent applications DE 19524287 A1 and DE 19547457 A1 . In the preferred embodiment of the invention, the solid detergents are in tablet form, these tablets preferably having rounded corners and edges, in particular for storage and transport reasons. The base of these tablets can be circular or rectangular, for example. Multi-layer tablets, in particular tablets with 2 or 3 layers, which can also have different colors, are particularly preferred. Blue-white or green-white or blue-green-white tablets are particularly preferred. The tablets can also contain pressed and unpressed parts. Shaped articles with a particularly advantageous dissolution rate are obtained if the granular constituents, before pressing, have a proportion of particles which have a diameter outside the range from 0.02 to 6 mm of less than 20, preferably less than 10% by weight. A particle size distribution in the range from 0.05 to 2.0 and particularly preferably from 0.2 to 1.0 mm is preferred.

    BeispieleExamples

    Beispiele 1 bis 6, Vergleichsbeispiel V1. In einer Waschmaschine (Miele W 918) wurden 3,5 kg Standard-Wäsche und ein Frottiertuch (welches zur Vorbehandlung zweimal mit einem Universalwaschmittel gewaschen wurde) in einem Vollwaschgang bei 90°C gewaschen. Jeweils zwei Waschmitteltabletten (40 g) der Zusammensetzung nach Tabelle 1 wurde unmittelbar vor dem Versuch in die Einspülkammer gegeben. Nach dem Waschgang wurde das Frottiertuch 24 Stunden bei Raumtemperatur getrocknet und anschließend einem Panel-Test von 20 Personen unterzogen. Jede Person vergab eine Note zwischen 1 und 4 (1 = hart; 4 = sehr weich). Aus dem Durchschnitt ergab sich die Bewertung für die Produkte, die ebenfalls Tabelle 1 zu entnehmen ist.
