Die Bleichepartikel werden beispielsweise nicht abgerieben.Such a laundry aid article has the desired advantages in terms of simple and portioned dosage. By embedding the bleach in a film-forming polymer, the bleach particles are effectively fixed on the textile substrate. The bleaching particles are not rubbed off, for example.
Da Phthalimidoperoxoalkansäuren, wie insbesondere 6-Phthalimidoperoxohexansäure (PAP), hocheffiziente Bleichmittel sind, werden diese in einer bevorzugten Ausführungsform der Erfindung als Bleichmittel eingesetzt. Bei Einsatz von Phthalimidoperoxoalkansäuren und insbesondere von PAP kann die Menge an eingesetztem Bleichmittel klein gehalten werden. Dies hat zur Folge, dass der Waschhilfsmittelartikel an sich nicht zu steif bzw. starr wird, sondern flexibel bleibt.Since phthalimidoperoxoalkanoic acids, such as, in particular, 6-phthalimidoperoxohexanoic acid (PAP), are highly efficient bleaching agents, in a preferred embodiment of the invention they are used as bleaching agents. When using phthalimidoperoxoalkanoic acids and in particular PAP, the amount of bleach used can be kept small. As a result, the auxiliary washing article per se does not become too stiff or rigid, but remains flexible.
Das film-bildende Polymer ist ausgewählt aus der Gruppe umfassend Polyvinylalkohol, hochmolekulares Polyethylenglycol, Polyvinylpyrrolidon, Copolymere von Vinylpyrrolidon und Vinylimidazol, Stärkeether, Celluloseether, Polyacrylate und Mischungen daraus.The film-forming polymer is selected from the group consisting of polyvinyl alcohol, high molecular weight polyethylene glycol, polyvinylpyrrolidone, copolymers of vinylpyrrolidone and vinylimidazole, starch ethers, cellulose ethers, polyacrylates and mixtures thereof.
Diese Polymere bilden stabile, geschlossene Filme und helfen, die Waschhilfsmittelzusammensetzung samt der darin enthaltenen Bleichepartikel auf dem textilen Substrat zu fixieren. Zusätzlich sind diese Polymere wasserlöslich oder wasserdispergierbar. Einige der Polymere weisen weitere Wirkungen auf. So wird bei Verwendung von Polyvinylpyrrolidon oder eines Copolymeren von Vinylpyrrolidon und Vinylimidazol verhindert, dass Farbstoffe von dunkleren Textilien, die sich beim Waschvorgang von dem Textil lösen, auf ein helleres Textil übertragen werden und dort zu Verfärbungen und/oder Vergrauungen führen. Carboxymethylcellulose verhindert, dass bereits gelöster Schmutz, der sich bei der Vorbehandlung und/oder beim Waschvorgang von einem Textil bereits gelöst hat, wieder auf demselben oder einem anderen Textil ablagert. Polyacrylate dienen der Enthärtung des Wassers und unterstützen die Waschwirkung durch ihre Alkalität sowie durch Herauslösen von Calcium- und Magnesium-Ionen aus Schmutz/Faserbrücken.These polymers form stable, closed films and help to fix the auxiliary washing composition together with the bleaching particles contained therein on the textile substrate. In addition, these polymers are water-soluble or water-dispersible. Some of the polymers have further effects. Thus, when using polyvinylpyrrolidone or a copolymer of vinylpyrrolidone and vinylimidazole prevents dyes from darker textiles, which dissolve in the washing process of the textile, are transferred to a lighter textile and there lead to discoloration and / or graying. Carboxymethyl cellulose prevents already dissolved dirt, which has already dissolved in the pretreatment and / or during the washing process of a textile, again deposited on the same or another textile. Polyacrylates serve to soften the water and support the washing effect by their alkalinity and by leaching of calcium and magnesium ions from dirt / fiber bridges.
Zur Verbesserung der Haptik des Waschhilfsmittelartikels enthalten diese einen Weichmacher für das film-bildende Polymer ausgewählt aus der Gruppe umfassend 1,2-Propandiol, 1,3-Propandiol, Ethylenglycol, Diethylenglycol, 2,3-Butandiol, Triethylcitrat, Paraffinöl und Mischungen daraus.To improve the feel of the auxiliary detergent article, these contain a plasticizer for the film-forming polymer selected from the group comprising 1,2-propanediol, 1,3-propanediol, ethylene glycol, diethylene glycol, 2,3-butanediol, triethyl citrate, paraffin oil and mixtures thereof.

In einer weiteren, bevorzugten Ausführungsform liegt auf dem Substrat wenigstens eine weitere Zusammensetzung verfestigt vor. Neben der bleichmittelhaltigen Waschhifsmittelzusammensetzung kann eine weitere, beispielsweise eine bleichmittelfreie Waschhilfsmittelzusammensetzung und/oder eine Textil-pflegende Zusammensetzung, auf dem textilen Substrat vorliegen und so der Waschhilfsmittelartikel um eine weitere Funktionalität erweitert werden. In einem solchen Waschhilfsmittelartikel können üblicherweise inkompatible Inhaltsstoffe eines Waschmittels gemeinsam, in einem Produkt formuliert werden.In a further preferred embodiment, at least one further composition is solidified on the substrate. In addition to the bleach-containing detergent composition, another, for example, a bleach-free detergent additive composition and / or a textile-care composition can be present on the textile substrate and thus the laundry aid article can be extended by a further functionality. In such a laundry aid article, incompatible ingredients of a detergent may commonly be formulated together in a product.
Dabei kann es bevorzugt sein, dass die bleichmittelhaltige Waschhifsmittelzusammensetzung eine Farbe aufweist, die von der Farbe der weiteren Zusammensetzung verschieden ist, um den Verbrauchern auch visuell zu zeigen, dass der beschichtete textile Waschhilfsmittelartikel mehrere Funktionalitäten besitzt.In this case, it may be preferred that the bleach-containing detergent composition has a color which is different from the color of the further composition, in order to prevent the To visually show consumers that the coated textile detergent adjuvant has multiple functionalities.
Es ist bevorzugt, dass das textile Substrat ein Gewebe oder ein Vlies ist. Gewebe und Vliese weisen eine hohe Strapazierfähigkeit und gute Beständigkeit auf, so dass diese textilen Substrate den hohen mechanischen Belastungen während des Waschvorgangs, insbesondere in einer Waschmaschine, standhalten.It is preferred that the textile substrate is a woven or non-woven fabric. Fabrics and nonwovens have high durability and good resistance, so that these textile substrates can withstand the high mechanical loads during the washing process, especially in a washing machine.
Es kann bevorzugt sein, dass die bleichmittelhaltige Waschhilfsmittelzusammensetzung und die weitere Zusammensetzung nebeneinander auf dem textilen Substrat angeordnet sind.It may be preferred that the bleach-containing auxiliary washing composition and the further composition are arranged side by side on the textile substrate.

Die Ausmaße des als Flächengebilde vorliegenden textilen Substrats sollten eine leichte Handhabbarkeit des Waschhilfsmittelartikels zulassen und zum Beispiel 10 cm x 10 cm oder 15 cm x 15 cm betragen, obwohl auch andere Größen möglich sind. Das textile Substrat und damit der Waschhilfsmittelartikel kann von beliebiger Flächenform, beispielsweise quadratisch, rechteckig, dreieckig, rund, oval, herzförmig, buchstaben- oder wortförmig oder der Wiedergabe einer Marke entsprechend sein. Das textile Substrat kann jede beliebige Farbe aufweisen oder im Wesentlichen weiß sein; seine Oberfläche kann im Wesentlichen glatt oder herstellungsbedingt texturiert sein. Vorzugsweise weist das textile Substrat und damit der Waschhilfsmittelartikel eine Oberfläche (bezogen auf eine Seite) von 40 cm2 bis 800 cm2 auf. In einer Ausführungsform der Erfindung ist das textile Substrat zumindest an Teilen seiner Oberflächen aufgeraut und weist so eine Oberflächenvergrößerung auf.The dimensions of the fabric substrate of the present invention should allow for easy handling of the laundry aid article, for example, 10 cm x 10 cm or 15 cm x 15 cm, although other sizes are possible. The textile substrate and thus the auxiliary washing article may be of any surface shape, for example square, rectangular, triangular, round, oval, heart-shaped, letter-shaped or word-like or the reproduction of a brand. The textile substrate may be any color or substantially white; its surface may be substantially smooth or textured due to manufacturing. Preferably, the textile substrate and thus the auxiliary washing article has a surface area (in relation to one side) of 40 cm 2 to 800 cm 2 . In one embodiment of the invention, the textile substrate is roughened at least on parts of its surfaces and thus has an increase in surface area.
In einer weiteren bevorzugten Ausführungsform weist das textile Substrat eine Ausrüstung auf. Unter einer Ausrüstung wird im Rahmen dieser Anmeldung eine kurzzeitige oder dauerhafte, chemische und/oder physikalische Veränderung des wasserunlöslichen Substrats verstanden, die diesem bestimmte Gebrauchseigenschaften, wie beispielsweise Farbfängereigenschaften, Schmutzfängereigenschaften oder antimikrobielle Wirkung, vermittelt.

This change can be made to the fibers, which later form the water-insoluble textile substrate, or to the water-insoluble textile substrate.
Die Ausrüstung der Fasern kann beispielsweise mittels eines so genannten Aufziehverfahrens erfolgen, bei dem die Fasern mit einer Anwendungsflotte, das heißt beispielsweise mit einer Lösung, Dispersion oder ähnlichem einer Farb-fangenden und/oder Schmutz-fangenden Verbindung, behandelt werden. Während der Behandlung zieht die eingesetzte Farb-fangenden und/oder Schmutz-fangende Verbindung aus der Anwendungsflotte auf die behandelten Fasern gleichmäßig auf. Alternativ kann das wasserunlösliche textile Substrat in die Anwendungsflotte getaucht oder mit dieser bedruckt oder besprüht werden. Die antimikrobielle Ausrüstung kann beispielsweise durch Einarbeiten von Silberfäden während der Herstellung des textilen Substrats oder durch Aufbringen von Silberverbindungen, wie beispielsweise SILVERPLUS® (ex Rudolf Chemie), erfolgen.The finishing of the fibers can be done, for example, by means of a so-called wind-up process in which the fibers are treated with an application liquor, that is, for example, with a solution, dispersion or the like of a color-catching and / or dirt-trapping compound. During treatment, the color-catching and / or soil-collecting compound used from the application liquor draws on the treated fibers evenly. Alternatively, the water-insoluble textile substrate can be dipped into the application liquor or printed or sprayed with it.

Derartige Tenside sind in der erfindungsgemäß auf das textile Substrat aufzubringenden bleichmittelhaltigen Waschhilfsmittelzusammensetzung in Mengen von vorzugsweise 1 Gew.-% bis 25 Gew.-%, insbesondere von 5 Gew.-% bis 15 Gew.%, enthalten.Such surfactants are present in the bleach-containing auxiliary washing composition according to the invention to be applied to the textile substrate in amounts of preferably from 1% by weight to 25% by weight, in particular from 5% by weight to 15% by weight.
Durch das Vorhandensein einer weiteren Zusammensetzung, welche verfestigt auf dem textilen Substrat vorliegt, können dem Waschhilfsmittelartikel weitere Funktionalitäten vermittelt werden. Insbesondere kann die weitere Zusammensetzung Inhaltsstoffe enthalten, die mit Inhaltsstoffen der bleichmittelhaltigen Waschhilfsmittelzusammensetzung inkompatibel sind bzw. die erst in der Waschflotte mit Inhaltsstoffen der bleichmittelhaltigen Waschhilfsmittelzusammensetzung in Kontakt kommen sollen. Inhaltsstoffe der weiteren Zusammensetzung können insbesondere Tenside, optischen Aufheller, Bleichaktivatoren, Bleichkatalysatoren, Enzyme, Kohlenwasserstoffe, Gerüststoffe, Duftstoffe und Mischungen daraus sein.Due to the presence of a further composition which is solidified on the textile substrate, further functionalities can be imparted to the auxiliary detergent article. In particular, the further composition may contain ingredients which are incompatible with ingredients of the bleach-containing detergent auxiliary composition or which are intended to come into contact with ingredients of the bleach-containing detergent auxiliary composition only in the wash liquor. Ingredients of the further composition may in particular be surfactants, optical brighteners, bleach activators, bleach catalysts, enzymes, hydrocarbons, builders, fragrances and mixtures thereof.
Vorzugsweise ist die weitere Zusammensetzung eine weitere, bleichmittelfreie Waschhilfsmittelzusammensetzung, welche beispielsweise ein anderes Auflöseprofil als die erste bleichmittelhaltige Waschhilfsmittelzusammensetzung hat und so ihre Inhaltsstoffe (beispielsweise Enzyme) zu einem anderen (späteren) Zeitpunkt im Waschvorgang freisetzt.Preferably, the further composition is another, bleach-free, laundry aid composition which, for example, has a different dissolution profile than the first bleach-containing laundry aid composition, thus releasing its ingredients (e.g., enzymes) at a different (later) time in the wash.
Die bleichmittelhaltige Waschhilfsmittelzusammensetzung und die weitere Zusammensetzung können in einer Ausführungsform zumindest teilweise überlappend auf dem textilen Substrat angeordnet sein.The bleach-containing laundry aid composition and the further composition may in one embodiment be arranged at least partially overlapping on the textile substrate.
In einer alternativen Ausführungsform sind die bleichmittelhaltige Waschhilfsmittelzusammensetzung und die weitere Zusammensetzung nebeneinander auf dem textilen Substrat angeordnet.In an alternative embodiment, the bleach-containing detergent additive composition and the further composition are arranged side by side on the textile substrate.
In einer bevorzugten Ausführungsform weist die bleichmittelhaltige Waschhilfsmittelzusammensetzung eine Farbe auf, die von der Farbe der weiteren Zusammensetzung verschieden ist.In a preferred embodiment, the bleach-containing detergent aid composition has a color which is different from the color of the further composition.
In allen Ausführungsformen muss nicht die gesamte Oberfläche des textilen Substrats mit der verfestigten bleichmittelhaltigen Waschhilfsmittelzusammensetzung und der gegebenenfalls vorhandenen weiteren Zusammensetzung bedeckt sein, solange die bleichmittelhaltige Waschhifsmittelzusammensetzung in mindestens einem Teil der Substratoberfläche, einer Zone, auf dem Substrat vorliegt.In all embodiments, the entire surface of the textile substrate need not be covered with the solidified bleach-containing detergent aid composition and optional further composition as long as the bleach-containing detergent composition is present in at least a portion of the substrate surface, a zone, on the substrate.
Die bleichmittelhaltige Waschhilfsmittelzusammensetzung und die gegebenenfalls vorliegenden weiteren Zusammensetzungen können auf eine oder beide Seiten des textilen Substrats aufgebracht werden. Vorzugsweise werden die bleichmittelhaltige Waschhilfsmittezusammensetzung und die gegebenenfalls vorliegenden weiteren Zusammensetzungen auf einer Seite des textilen Substrats aufgebracht. Dies hat insbesondere den Vorteil, dass der Verbraucher beim Dosieren des Waschhilfsmittelartikels nicht in direkten Kontakt mit den Zusammensetzungen kommen muss, sondern den Waschhilfsmittelartikel auf der Zusammensetzungs-freien Oberfläche problemlos anfassen kann.The bleach-containing laundry aid composition and optional further compositions may be applied to one or both sides of the textile substrate. Preferably, the bleach-containing auxiliary washing composition and optional further compositions are applied to one side of the textile substrate. This has the particular advantage that the consumer does not have to come into direct contact with the compositions when dosing the laundry aid article, but can easily handle the laundry aid article on the composition-free surface.
Es ist möglich, die bleichmittelhaltige Waschhilfsmittelzusammensetzung als flüssige Lösung, Aufschlämmung oder als Paste auf das textile Substrat aufzubringen und anschließend einen Trocknungsschritt durchzuführen und dabei das Aufschlämmungs- beziehungsweise Lösungsmittel, beispielsweise Wasser, so weit zu entfernen, dass sich die bleichmittelhaltige Waschhilfsmittelzusammensetzung auf dem textilen Substrat durch Trocknen verfestigt. Alternativ kann die bleichmittelhaltige Waschhilfsmittelzusammensetzung als erwärmte Schmelze auf das textile Substrat aufgebracht werden und diese anschließend durch Abkühlen verfestigen zu lassen. Dabei muss nicht die gesamte bleichmittelhaltige Waschhilfsmittelzusammensetzung durch Schmelzen verflüssigt vorliegen, es ist im Gegenteil möglich, dass die Schmelze teilchenförmige Feststoffe, wie beispielsweise anorganische Builder enthält.It is possible to apply the bleach-containing detergent additive composition as a liquid solution, slurry or paste to the textile substrate and then perform a drying step while removing the slurry or solvent, for example water, to such an extent that the bleach-containing wash aid composition is applied to the textile substrate solidified by drying. Alternatively, the bleach-containing auxiliary washing composition can be applied to the textile substrate as a heated melt and then allowed to solidify by cooling. It is not necessary for the entire bleach-containing detergent additive composition to be liquefied by melting; on the contrary, it is possible for the melt to contain particulate solids, such as, for example, inorganic builders.
Zunächst wurde eine kommerziell erhältliche wässrige PAP-Dispersion (Euroco® LX von Solvay) zentrifugiert. Nach Abdekantieren des Überstands wurden die PAP-Partikel mit destilliertem Wasser aufgeschlämmt und erneut zentrifugiert. Die erhaltene PAP-Paste wies einen iodometrisch ermittelten Aktivsubstanzgehalt von 45 % auf.First, a commercially available aqueous PAP dispersion (Euroco® LX from Solvay) was centrifuged. After decanting the supernatant, the PAP particles were slurried with distilled water and recentrifuged. The resulting PAP paste had an iodometrically determined active substance content of 45%.
