Beschreibung der ErfindungDescription of the invention

Gegenstand der vorliegenden Erfindung ist Verwendung von niedermolekularen Proteinhydrolysaten als entzündungshemmende, pflegende Wirkstoffe in Wasch- und Reinigungsmitteln, vorzugsweise in Waschmitteln, Bügelhilfsmitteln, Weichspülern und Trockner-Zusätzen.The present invention relates to the use of low molecular weight protein hydrolyzates as anti-inflammatory, nourishing active ingredients in detergents and cleaning agents, preferably in Detergents, ironing aids, fabric softeners and dryer additives.

Ebenso Gegenstand der Erfindung ist die Verwendung von niedermolekularen Proteinhydrolysaten zur Gewebekonditionierung in Wasch- und Reinigungsmitteln, vorzugsweise in Waschmitteln, Bügelhilfsmitteln, Weichspülern und Trockner-Zusätzen, dadurch gekennzeichnet, dass durch die Proteinhydrolysate die Fasern repariert und geglättet werden.The invention also relates to the use of low molecular weight protein hydrolyzates for Tissue conditioning in detergents and cleaning agents, preferably in detergents, ironing aids, Fabric softener and dryer additives, characterized in that by the protein hydrolyzates the fibers are repaired and smoothed.

In einer weiteren Ausführungsform wird Verwendung von niedermolekularen Proteinhydrolysaten zur Gewebekonditionierung in Wasch- und Reinigungsmitteln, vorzugsweise in Waschmitteln, Bügelhilfsmitteln, Weichspülern und Trockner-Zusätzen beschrieben, dadurch gekennzeichnet, dass durch die Proteinhydrolysate die Fasern umhüllt, verstärkt und geschützt werdenIn a further embodiment, the use of low molecular weight protein hydrolyzates is used Tissue conditioning in detergents and cleaning agents, preferably in detergents, ironing aids, Softener and dryer additives described, characterized in that by the Protein hydrolyzates that envelop, strengthen and protect the fibers

Weiterhin wird die Verwendung von niedermolekularen Proteinhydrolysaten zur Gewebekonditionierung in Wasch- und Reinigungsmitteln, vorzugsweise in Waschmitteln, Bügelhilfsmitteln, Weichspülern und Trockner-Zusätzen beansprucht, dadurch gekennzeichnet, dass durch das Aufziehen der Proteinhydrolysate auf die Fasern deren elektrostatische Auflandung gemindert wirdFurthermore, the use of low molecular weight protein hydrolyzates for tissue conditioning in detergents and cleaning agents, preferably in detergents, ironing aids, fabric softeners and Dryer additives claimed, characterized in that by pulling up the protein hydrolyzates on the fibers whose electrostatic landing is reduced

Des weiteren werden niedermolekularen Proteinhydrolysaten zur Gewebekonditionierung in Waschund Reinigungsmitteln beansprucht, vorzugsweise in Waschmitteln, Bügelhilfsmitteln, Weichspülern und Trockner-Zusätzen, dadurch gekennzeichnet, dass durch das Aufziehen der Proteinhydrolysate auf die Fasern deren Wiederanschmutzung gemindert wird.Furthermore, low molecular weight protein hydrolyzates are used for tissue conditioning in detergents and cleaning agents, preferably in detergents, ironing aids, fabric softeners and dryer additives, characterized in that the re- soiling is reduced by pulling the protein hydrolyzates onto the fibers.

Insbesondere bei der Verwendung in Waschmitteln, Weichspülern, Bügelhilfsmittel sowie Trockner-Zusätze, bewirken die eingesetzten Proteinhydrolysate eine sehr gute dermatologische Verträglichkeit der Wäsche, auch für die empfindliche Haut. Hier wirken die Proteinhydrolysate, die durch den Wasch-, Weichspül- oder Trocknungsvorgang, oder durch direktes Auftragen (z.B. Bügelhilfsmittel) an der Faser haften, durch das Tragen der Textilfasern bzw. Textilien direkt auf die Haut.
Zusätzlich wird der Tragekomfort der Wäsche durch ein angenehmeres Tragegefühl verbessert. Dies wird durch die Gewebekonditionierung, insbesondere durch eine Glättung der Fasern bewirkt, die durch den Zusatz von Proteinhydrolysaten repariert werden können. Die Fasern werden durch die Proteine umhüllt und erhalten so zusätzliche physiko-chemische Stabilität, sowie eine glattere Oberfläche.
Die glattere Oberfläche wird durch Filmbildung bzw. durch Penetration der Proteinhydrolysate und der Reparatur der geschädigten Fasern erreicht.
Durch die glattere Oberfläche wird die mechanische Reizung der Haut durch das Tragen der so behandelten Wäschestücke gemindert.
Darüber hinaus ist bei den Textilien, die mit proteinhaltigen Agentien behandelt wurden, eine geringere Wiederanschmutzung zu beobachten. Auch ist die elektrostatische Aufladung dieser Gewebe geringer.Especially when used in detergents, fabric softeners, ironing aids and dryer additives, the protein hydrolyzates used have a very good dermatological compatibility with the laundry, even for sensitive skin. The protein hydrolyzates, which adhere to the fiber through the washing, fabric softening or drying process or through direct application (eg ironing aids), act directly on the skin by wearing the textile fibers or textiles.
In addition, the comfort of the laundry is improved by a more comfortable fit. This is brought about by tissue conditioning, in particular by smoothing the fibers, which can be repaired by adding protein hydrolyzates. The fibers are encased in the proteins, giving them additional physico-chemical stability and a smoother surface.
The smoother surface is achieved by film formation or by penetration of the protein hydrolyzates and the repair of the damaged fibers.
Due to the smoother surface, the mechanical irritation of the skin is reduced by wearing the laundry items treated in this way.
In addition, less re-soiling can be observed for textiles that have been treated with protein-containing agents. The electrostatic charge on these tissues is also lower.

Es wurde gefunden, dass niedermolekulare Proteinhydrolysate, insbesondere pflanzlicher Herkunft und speziell niedermolekulare Weizenproteinhydrolysate eine ausgeprägte entzündungshemmende Wirkung aufweisen.It has been found that low molecular weight protein hydrolyzates, especially of vegetable origin and Low molecular weight wheat protein hydrolyzates in particular have a pronounced anti-inflammatory effect exhibit.

Immer mehr Konsumenten klagen über empfindliche, sensible oder sogar gereizte Haut. Die entzündungshemmende Wirkung der Proteinhydrolysate stellt daher eine interessante Eigenschaft dar. Dieser Effekt wirkt sich üblicherweise nicht nur wohltuend und beruhigend auf die Haut aus, sondern ist in der Lage, Irritationen der Haut effektiv zu vermeiden. Niedermolekulare Weizenproteinhydrolysate zeigen in Untersuchungen sogar eine bessere Wirksamkeit als Acetylsalicylsäure.More and more consumers complain about sensitive, sensitive or even irritated skin. The anti-inflammatory Effect of protein hydrolyzates is therefore an interesting property Effect usually not only has a beneficial and soothing effect on the skin, but is also in the Able to effectively avoid skin irritation. Low molecular weight wheat protein hydrolyzates show in Studies even outperformed acetylsalicylic acid.

Auf diese Weise können sie die Haut beruhigen und vor Reizungen schützen und dadurch die Trageeigenschaften der Gewebe verbessern. Daher bietet sich der Einsatz der niedermolekularen Porteinhydrolysate in Waschmitteln an. Die Proteinhydrolysate wirken dann über die gewaschenen Textilien bzw. Fasern bei direktem Hautkontakt entzündungshemmend. Eine Reizung der Haut wird hierdurch minimiert. Ebenso können die Proteinhydrolysate in Finishing-Produkten, wie Bügelhilfen, Weichspüler und Trockner-Zusätzen eingebracht werden.In this way, they can soothe the skin and protect it from irritation and thus the wearing properties improve the tissues. Therefore, the use of low molecular weight port hydrolyzates is an option in detergents. The protein hydrolyzates then act on the washed textiles or Anti-inflammatory fibers when in direct contact with the skin. This minimizes skin irritation. The protein hydrolyzates can also be used in finishing products such as ironing aids, fabric softeners and Dryer additives are introduced.

Unter Trockner-Zusätzen sind u.a. Kissen oder Tücher zu verstehen, die proteinhydrolysathaltige Formulierung enthalten und beim Trocknen der Wäsche direkt in den Trockner gegeben werden. Die entzündungshemmende Wirkung von Proteinhydrolysaten entfaltet sich hier indirekt über die Glättung der Faser der getragenen Textilien, die hier eine geringere mechanische Irritation der Haut bewirken.Dryer additives include Pillows or towels to understand the protein hydrolyzed formulation included and put directly into the dryer when drying the laundry. The anti-inflammatory The effect of protein hydrolyzates unfolds indirectly through the smoothing of the Fiber of the worn textiles, which cause less mechanical irritation to the skin.

As a result, low molecular weight protein hydrolyzates have such a small molecular size that these "microprotein agents" are even able to penetrate and repair, strengthen and protect the textile fiber.

In der Aminosäurezusammensetzung der erfindungsgemäßen niedermolekularen Proteinhydrolysate ist insbesondere der hohe Gehalt an Glutaminsäure hervorzuheben. Glutaminsäure ist in der Natur allgemein weit verbreitet und daher in fast allen Proteinen zu finden. Den höchsten Gehalt weist allerdings Weizenprotein auf mit in der Regel mehr als 30 % Glutaminsäure. Von Gluten, dem Protein des Weizenklebers, aus dem Glutaminsäure zuerst gewonnen wurde, leitet sich daher auch der Name dieses Proteinbausteins ab. Obwohl es sich hierbei nicht um eine essentielle Aminosäure handelt, spielt Glutaminsäure eine wichtige Rolle in verschiedenen Stoffwechselprozessen. Dabei bildet sie u.a. auch die Vorstufe für Prolin.In the amino acid composition of the low molecular weight protein hydrolyzates according to the invention to emphasize in particular the high content of glutamic acid. Glutamic acid is common in nature widespread and therefore found in almost all proteins. However, the highest salary shows Wheat protein with usually more than 30% glutamic acid. Of gluten, the protein of wheat gluten, the name from which glutamic acid was obtained is therefore derived Protein building block. Although this is not an essential amino acid, glutamic acid does play play an important role in various metabolic processes. Among other things, it forms also the Proline for proline.

Die Einsatzmenge der niedermolekularen Proteinhydrolysate beträgt -bezogen auf die Endformulierung- 0,1 bis 10, vorzugsweise 0,2 bis 8 und insbesondere 0,5 bis 6 Gew.-% Aktivsubstanz.The amount of the low molecular weight protein hydrolyzates is based on the final formulation. 0.1 to 10, preferably 0.2 to 8 and in particular 0.5 to 6% by weight of active substance.

Bevorzugte Polyacetale werden aus Dialdehyden wie Glyoxal, Glutaraldehyd, Terephthalaldehyd sowie deren Gemischen und aus Polyolcarbonsäuren wie Gluconsäure und/oder Glucoheptonsäure erhalten.In particular, finely crystalline, synthetic and bound water-containing zeolite such as zeolite NaA in detergent quality is used as the solid builder . However, zeolite NaX and mixtures of NaA and NaX are also suitable. 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 minor 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 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, in particular 20 to 22% by weight of bound water. Suitable substitutes or partial substitutes for 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. Preferred crystalline phyllosilicates are those in which M in the general formula represents sodium and x assumes the values 2 or 3. In particular, both β- and γ-sodium disilicate Na 2 Si 2 O 5 .yH 2 O are preferred. The powder detergents according to the invention preferably contain 10 to 60% by weight of zeolite and / or crystalline layered silicates as solid builders, mixtures of zeolite and crystalline layered silicates in any ratio being particularly advantageous. In particular, it is preferred that the agents contain 20 to 50% by weight of zeolite and / or crystalline layered silicates. Particularly preferred agents contain up to 40% by weight of zeolite and in particular up to 35% by weight of zeolite, in each case based on the anhydrous active substance. Other suitable ingredients of the agents are water-soluble amorphous silicates; they are preferably used in combination with zeolite and / or crystalline layered silicates. Particularly preferred are agents which contain, above all, sodium silicate with a molar ratio (module) Na 2 O: SiO 2 of 1: 1 to 1: 4.5, preferably of 1: 2 to 1: 3.5. The content of amorphous sodium silicates in the agents is preferably up to 15% by weight and preferably between 2 and 8% by weight. Phosphates such as tripolyphosphates, pyrophosphates and orthophosphates can also be present in small amounts in the compositions. The content of the phosphates in the compositions is preferably up to 15% by weight, but in particular 0 to 10% by weight. In addition, the compositions can additionally contain layered silicates of natural and synthetic origin. 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. Layered silicates are preferably used which are largely free of calcium ions and strongly coloring iron ions due to an alkali treatment. Usable organic builders are, for example, the polycarboxylic acids preferably used in the form of their sodium salts, such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids, aminocarboxylic acids, nitricotrylic acid (NTA), provided that such use is not objectionable for ecological reasons. and mixtures of these. Preferred salts are the salts of polycarboxylic acids such as citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, sugar acids and mixtures of these. 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). 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. The use of polymeric polycarboxylates is not absolutely necessary. However, if polymeric polycarboxylates are used, agents are preferred which are biodegradable polymers, for example terpolymers, the monomers acrylic acid and maleic acid or salts thereof, and vinyl alcohol or vinyl alcohol derivatives, or the monomers acrylic acid and 2-alkylallylsulfonic acid or salts thereof as well as sugar derivatives. Terpolymers are particularly preferred.

Unter den als Peroxy-Bleichmittel dienenden Verbindungen haben das Natriumperborat-Tetrahydrat und das Natriumperborat-Monohydrat eine besondere Bedeutung. Weitere Bleichmittel sind beispielsweise Peroxycarbonat, Citratperhydrate sowie H2O2-liefernde persaure Salze der Persäuren wie Perbenzoate, Peroxyphthalate oder Diperoxydodecandisäure. Sie werden üblicherweise in Mengen von 8 bis 25 Gew.-% eingesetzt. Bevorzugt ist der Einsatz von Natriumperborat-Monohydrat in Mengen von 10 bis 20 Gew.-% und insbesondere von 10 bis 15 Gew.-%. Durch seine Fähigkeit, unter Ausbildung des Tetrahydrats freies Wasser binden zu können , trägt es zur Erhöhung der Stabilität des Mittels bei.Among the compounds used as peroxy bleaching agents , sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance. Further bleaching agents are, for example, peroxy carbonate, citrate perhydrates and H2O2-providing peracid salts of peracids such as perbenzoates, peroxyphthalates or diperoxydodecanedioic acid. They are usually used in amounts of 8 to 25% by weight. The use of sodium perborate monohydrate in amounts of 10 to 20% by weight and in particular 10 to 15% by weight is preferred. Due to its ability to bind free water with the formation of tetrahydrate, it contributes to increasing the stability of the agent.

Als Viskositätsregulatoren können beispielsweise gehärtetes Rizinusöl, Salze von langkettigen Fettsäuren, die vorzugsweise in Mengen von 0 bis 5 Gew.-% und insbesondere in Mengen von 0,5 bis 2 Gew.-%, beispielsweise Natrium-, Kalium-, Aluminium-, Magnesium- und Titanstearate oder die Natrium- und/oder Kaliumsalze der Behensäure, sowie weitere polymere Verbindungen eingesetzt werden. Zu den letzteren gehören bevorzugt Polyvinylpyrrolidon, Urethane und die Salze polymerer Polycarboxylate, beispielsweise homopolymerer oder copolymerer Polyacrylate, Polymethacrylate und insbesondere Copolymere der Acrylsäure mit Maleinsäure, vorzugsweise solche aus 50 % bis 10 % Maleinsäure. Die relative Molekülmasse der Homopolymeren liegt im allgemeinen zwischen 1000 und 100000, die der Copolymeren zwischen 2000 und 200000, vorzugsweise zwischen 50000 bis 120000, bezogen auf die freie Säure. Insbesondere sind auch wasserlösliche Polyacrylate geeignet, die beispielsweise mit etwa 1 % eines Polyallylethers der Sucrose quervernetzt sind und die eine relative Molekülmasse oberhalb einer Million besitzen. Beispiele hierfür sind die unter dem Namen Carbopol® 940 und 941 erhältlichen Polymere mit verdickender Wirkung. Die quervernetzten Polyacrylate werden vorzugsweise in Mengen nicht über 1 Gew.-%, vorzugsweise in Mengen von 0,2 bis 0,7 Gew.-% eingesetzt. Die Mittel können zusätzlich etwa 5 bis 20 Gew.-% eines partiell veresterten Copolymerisats enthalten.

Bevorzugte Copolymerisate enthalten als ethylenisch ungesättigtes Dicarbonsäureanhydrid Maleinsäureanhydrid. Die partiell veresterten Copolymerisate können entweder in Form der freien Säure oder vorzugsweise in partiell oder vollständig neutralisierter Form vorliegen. Vorteilhafterweise werden die Copolymerisate in Form einer wäßrigen Lösung, insbesondere in Form einer 40 bis 50 Gew.-%igen Lösung eingesetzt. Die Copolymerisate leisten nicht nur einen Beitrag zur Primär- und Sekundärwaschleistung des flüssigen Wasch- und Reinigungsmittels, sondern bewirken auch eine gewünschte Viskositätserniedrigung der konzentrierten flüssigen Waschmittel. Durch den Einsatz dieser partiell veresterten Copolymerisate werden konzentrierte wäßrige Flüssigwaschmittel erhalten, die unter dem alleinigen Einfluß der Schwerkraft und ohne Einwirkung sonstiger Scherkräfte fließfähig sind. Vorzugsweise beinhalten die konzentrierten wäßrigen Flüssigwaschmittel partiell veresterte Copolymerisate in Mengen von 5 bis 15 Gew.-% und insbesondere in Mengen von 8 bis 12 Gew.-%. Viscosity regulators which can be used are, for example, hardened castor oil, salts of long-chain fatty acids, preferably in amounts of 0 to 5% by weight and in particular in amounts of 0.5 to 2% by weight, for example sodium, potassium, aluminum, magnesium - And titanium stearates or the sodium and / or potassium salts of behenic acid, and other polymeric compounds are used. The latter preferably include polyvinylpyrrolidone, urethanes and the salts of polymeric polycarboxylates, for example homopolymeric or copolymeric polyacrylates, polymethacrylates and in particular copolymers of acrylic acid with maleic acid, preferably those composed of 50% to 10% maleic acid. The relative molecular weight of the homopolymers is generally between 1000 and 100000, that of the copolymers between 2000 and 200000, preferably between 50,000 to 120,000, based on the free acid. Water-soluble polyacrylates which are crosslinked, for example, with about 1% of a polyallyl ether of sucrose and which have a relative molecular weight above one million are also particularly suitable. Examples of this are the polymers with thickening action available under the name Carbopol® 940 and 941. The crosslinked polyacrylates are preferably used in amounts not exceeding 1% by weight, preferably in amounts of 0.2 to 0.7% by weight. The agents can additionally contain about 5 to 20% by weight of a partially esterified copolymer. These partially esterified polymers are obtained by copolymerizing (a) at least one C 4 -C 28 olefin or mixtures of at least one C 4 -C 28 olefin with up to 20 mol% of C 1 -C 28 alkyl vinyl ethers and (b) ethylenically unsaturated dicarboxylic acid anhydrides with 4 to 8 carbon atoms in a molar ratio of 1: 1 to copolymers with K values from 6 to 100 and subsequent partial esterification of the copolymers with reaction products such as C 1 -C 13 alcohols, C 8 -C 22 fatty acids, C 1 -C 12 alkylphenols, secondary C 2 -C 30 amines or mixtures thereof with at least one C 2 -C 4 alkylene oxide or tetrahydrofuran and hydrolysis of the anhydride groups of the copolymers to give carboxyl groups, the partial esterification of the copolymers being carried out to the extent that 5 to 50% of the carboxyl groups of the copolymers are esterified. Preferred copolymers contain maleic anhydride as the ethylenically unsaturated dicarboxylic acid anhydride. The partially esterified copolymers can be present either in the form of the free acid or preferably in partially or completely neutralized form. The copolymers are advantageously used in the form of an aqueous solution, in particular in the form of a 40 to 50% strength by weight solution. The copolymers not only contribute to the primary and secondary washing performance of the liquid washing and cleaning agent, but also bring about a desired reduction in the viscosity of the concentrated liquid washing agent. The use of these partially esterified copolymers gives concentrated aqueous liquid detergents which are flowable under the sole influence of gravity and without the action of other shear forces. The concentrated aqueous liquid detergents preferably contain partially esterified copolymers in amounts of 5 to 15% by weight and in particular in amounts of 8 to 12% by weight.

In addition to mono- and polyfunctional alcohols and phosphonates, the agents can contain further enzyme stabilizers . For example, 0.5 to 1% by weight sodium formate can be used. 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 (H3BO3), metaboric acid (HBO2) and pyroboric acid (tetraboric acid H2B4O7), is particularly advantageous.

Die erfindungsgemäßen Flüssigwaschmittel weisen im allgemeinen Viskositäten zwischen 150 und 10000 mPas (Brookfield-Viskosimeter, Spindel 1, 20 Umdrehungen pro Minute, 20°C). Dabei sind bei den im wesentlichen wasserfreien Mitteln Viskositäten zwischen 150 und 5000 mPas bevorzugt. Die Viskosität der wäßrigen Mittel liegt vorzugsweise unter 2000 mPas und liegt insbesondere zwischen 150 und 1000 mPas.When used in machine washing processes, it can be advantageous to add conventional foam inhibitors to the agents.
