Description

Die Erfindung betrifft eine wasserlösliche Verpackung mit wenigstens zwei Kammern, die ein erstes flüssiges wasserarmes Wasch- oder Reinigungsmittel, ein zweites flüssiges wasserarmes Wasch- oder Reinigungsmittel und eine wasserlösliche Umhüllung enthält.The invention relates to a water-soluble packaging with at least two chambers containing a first liquid low-water detergent or cleaning agent, a second liquid low-water detergent or cleaning agent and a water-soluble wrapper.

Optische Aufheller (so genannte "Weißtöner") werden Wasch- oder Reinigungsmitteln zugesetzt, um Vergrauungen und Vergilbungen der behandelten textilen Flächengebilde zu beseitigen. Diese Stoffe ziehen auf die Faser auf und bewirken eine Aufhellung und vorgetäuschte Bleichwirkung, indem sie unsichtbare Ultraviolettstrahlung in sichtbares längerwelliges Licht umwandeln, wobei das aus dem Sonnenlicht absorbierte ultraviolette Licht als schwach bläuliche Fluoreszenz abgestrahlt wird und mit dem Gelbton der vergrauten bzw. vergilbten Wäsche reines Weiß ergibt. Wasch- oder Reinigungsmittel mit optischen Aufhellern werden auch oft als Universal-Waschmittel bezeichnet.Optical brighteners (so-called "whiteners") are added to detergents or cleaning agents in order to eliminate graying and yellowing of the treated textile fabrics. These fabrics impinge on the fiber and cause whitening and bleaching by transforming invisible ultraviolet radiation into visible longer wavelength light, emitting the ultraviolet light absorbed from the sunlight as faint bluish fluorescence, and pure with the yellowness of the grayed or yellowed wash White results. Detergents or cleaners with optical brighteners are also often referred to as universal detergents.

Um während des Waschens und/oder des Reinigens von gefärbten Textilien die Farbstoffablösung und/oder die Farbstoffübertragung auf andere Textilien wirksam zu unterdrücken, wird einem Wasch- oder Reinigungsmittel ein Farbübertragungsinhibitor zugesetzt. Dabei bildet der Farbübertragungsinhibitor meist Komplexe mit den Farbstoffen, die sich von den Textilien abgelöst haben und in der Waschflotte vorhanden sind, aus. Wasch- oder Reinigungsmittel mit Farbübertragungsinhibitor werden auch oft als Color-Waschmittel bezeichnet.To effectively suppress dye release and / or dye transfer to other fabrics during washing and / or cleaning of dyed fabrics, a color transfer inhibitor is added to a detergent or cleaning agent. In this case, the color transfer inhibitor usually forms complexes with the dyes which have detached themselves from the textiles and are present in the wash liquor. Detergents or color transfer inhibitor detergents are also often referred to as color detergents.

Versuche das Leistungsspektrum von flüssigen Universalwaschmitteln um die Eigenschaft der Verfärbungsinhibierung zu erweitern, scheiterten daran, dass optische Aufheller und Farbübertragungsinhibitoren in einer wässrigen Waschmittelmatrix mit herkömmlicher Zusammensetzung nicht kompatibel sind. So führt das gleichzeitige Einarbeiten eines optischen Aufhellers und eines polymeren Farbübertragungsinhibitors in eine flüssige Waschmittelmatrix sofort zu einer starken Trübung und anschließender Ausflockung oder Phasenseparation. Die Instabilitäten treten besonders stark bei konzentrierten oder wasserarmen flüssigen Wasch- oder Reinigungsmitteln auf.Attempts to extend the performance of liquid universal detergents by the property of discoloration inhibition have failed because optical brighteners and color transfer inhibitors are not compatible in an aqueous detergent matrix of conventional composition. Thus, the simultaneous incorporation of an optical brightener and a polymeric dye transfer inhibitor into a liquid detergent matrix immediately results in high turbidity and subsequent flocculation or phase separation. The instabilities occur particularly strong in concentrated or low-water liquid detergents or cleaners.

Aus der WO 2009/019136 A1 ist ein stabiles wässriges Wasch- oder Reinigungsmittel, enthaltend einen optischen Aufheller und einen Farbübertragungsinhibitor bekannt, welches einen pH-Wert in einem engen Bereich von 6,5 bis 7,5 aufweist.From the WO 2009/019136 A1 discloses a stable aqueous washing or cleaning composition containing an optical brightener and a color transfer inhibitor which has a pH in a narrow range of 6.5 to 7.5.

Es besteht weiterhin Bedarf, ein lagerstabiles, flüssiges wasserarmes Wasch- oder Reinigungsmittel bereitzustellen, welches einen optischen Aufheller und einen Farbübertragungsinhibitor enthält.There is still a need to provide a shelf-stable, liquid low-water detergent or cleaner which contains an optical brightener and a color transfer inhibitor.

Diese Aufgabe wird gelöst durch eine wasserlösliche Verpackung mit wenigstens zwei Kammern, die ein erstes flüssiges wasserarmes Wasch- oder Reinigungsmittel, enthaltend weniger als 15 Gew.-% Wasser ein zweites flüssiges wasserarmes Wasch- oder Reinigungsmittel enthaltend weniger als 15 Gew.-% Wasser und eine wasserlösliche Umhüllung enthält, wobei das erste flüssige wasserarme Wasch- oder Reinigungsmittel einen optischen Aufheller und anionisches und nichtionisches Tensid und das zweite wasserarme Wasch- oder Reinigungsmittel einen Farbübertragungsinhibitor und anionisches und nichtionisches Tensid enthält.This object is achieved by a water-soluble packaging having at least two chambers containing a first liquid low-water detergent or cleaner containing less than 15 wt .-% water, a second liquid low-water detergent or cleaner containing less than 15 wt .-% water and contains a water-soluble coating, wherein the first liquid water-poor detergent or cleaning agent contains an optical brightener and anionic and nonionic surfactant and the second low-water detergent or cleaning agent color transfer inhibitor and anionic and nonionic surfactant.

Es hat sich überraschenderweise gezeigt, dass optische Aufheller und Farbübertragungsinhibitoren jeweils in hohen Mengen stabil in ein flüssiges wasserarmes Wasch- oder Reinigungsmittel eingearbeitet werden können, das sich in einer wasserlöslichen Umhüllung befindet, ohne dass es zu einer Trübung, Phasenseparation und/oder Reaktion mit der wasserlöslichen Umhüllung kommt. Zusätzlich wird durch Einbringen des optischen Aufhellers und des Farbübertragungsinhibitors in unterschiedliche Kammern eine unerwünschte Reaktion der beiden Inhaltsstoffe miteinander verhindert.It has surprisingly been found that optical brighteners and color transfer inhibitors can each be incorporated in high amounts stable in a liquid low-water detergent or cleaning agent, which is in a water-soluble envelope, without causing turbidity, phase separation and / or reaction with the water-soluble cladding comes. In addition, by introducing the optical brightener and the color transfer inhibitor into different chambers, an undesirable reaction of the two ingredients with each other is prevented.

Es ist bevorzugt, dass der optische Aufheller aus den Substanzklassen der Distyrylbiphenyle, der Stilbene, der 4,4'-Diamino-2,2'-stilbendisulfonsäuren, der Cumarine, der Dihydrochinolinone, der 1,3-Diarylpyrazoline, der Naphthalsäureimide, der Benzoxazol-Systeme, der Benzisoxazol-Systeme, der Benzimidazol-Systeme, der durch Heterocyclen substituierten Pyrenderivate und Mischungen daraus ausgewählt ist. Diese Substanzklassen an optischen Aufhellern weisen eine hohe Stabilität, eine hohe Licht- und Sauerstoffbeständigkeit und eine hohe Affinität zu Fasern auf.It is preferred that the optical brightener from the substance classes of distyrylbiphenyls, the stilbenes, the 4,4'-diamino-2,2'-stilbenedisulfonic, the coumarins, the Dihydrochinolinone, the 1,3-diarylpyrazolines, the Naphthalsäureimide, the benzoxazole Systems, benzisoxazole systems, benzimidazole systems, heterocyclic substituted pyrene derivatives, and mixtures thereof. These classes of optical brighteners have high stability, high light and oxygen resistance, and high affinity for fibers.

In particular, however, alcohol ethoxylates having linear radicals of alcohols of native origin having 12 to 18 carbon atoms, for example coconut, palm, tallow or oleyl alcohol, and on average 5 to 8 EO per mole of alcohol are preferred. The preferred ethoxylated alcohols include, for example, C 12-14 alcohols with 4 EO or 7 EO, C 9-11 alcohols with 7 EO, C 13-15 alcohols with 5 EO, 7 EO or 8 EO, C 12-18 Alcohols with 5 EO or 7 EO and mixtures of these.

Bei dem flüssigen Wasch- oder Reinigungsmittel V1 zeigten sich bereits während der Herstellung Präzipitate während die flüssigen Wasch- oder Reinigungsmittel E1, E2, V2 und V3 klar und über mehrere Wochen lagerstabil waren.The liquid washing or cleaning agent V1 already showed precipitates during the production while the liquid detergents or cleaners E1, E2, V2 and V3 were clear and storage-stable for several weeks.

Zur Herstellung einer wasserlöslichen Verpackung mit den Wasch- oder Reinigungsmitteln E1 und E2 wurde eine Folie vom Typ M 8630 (ex Monosol) mit einer Dicke von 76 µm zum Ausbilden von zwei unterschiedlich großen Ausbuchtung mittels Vakuum in eine Mulde gezogen. Anschließend wurde die erste Ausbuchtung mit 11,7 g des ersten flüssigen Wasch- oder Reinigungsmittels E1 befüllt. Parallel wurde die zweite Ausbuchtung mit 23,3 g des zweiten flüssigen Wasch- oder Reinigungsmittels E2 befüllt. Nach Bedecken der mit den Mitteln befüllten Ausbuchtungen mit einer zweiten Lage einer Folie vom Typ M 8630 wurden die erste und zweite Lage miteinander versiegelt. Die Siegelungstemperatur betrug 150 °C und die Siegelungsdauer 1,1 Sekunden.To produce a water-soluble packaging with the detergents E1 and E2, a film of the type M 8630 (ex Monosol) with a thickness of 76 microns for forming two different sized bulge was pulled by means of vacuum in a trough. Subsequently, the first bulge filled with 11.7 g of the first liquid detergent or cleaning agent E1. In parallel, the second bulge was filled with 23.3 g of the second liquid detergent or cleaning agent E2. After covering the bulge-filled bulges with a second layer of M 8630 film, the first and second layers were sealed together. The sealing temperature was 150 ° C and the sealing time 1.1 seconds.

Zur Herstellung einer wasserlöslichen Verpackung mit dem Wasch- oder Reinigungsmittel V1, V2 oder V3 wurde eine Folie vom Typ M 8630 (ex Monosol) mit einer Dicke von 76 µm zum Ausbilden einer Ausbuchtung mittels Vakuum in eine Mulde gezogen. Anschließend wurde die Ausbuchtung mit je 35 g des flüssigen Wasch- oder Reinigungsmittels V1, V2 oder V3 befüllt. Nach Bedecken der mit dem Mittel V1, V2 oder V3 befüllten Ausbuchtung mit einer zweiten Lage einer Folie vom Typ M 8630 wurden die erste und zweite Lage miteinander versiegelt. Die Siegelungstemperatur betrug 150 °C und die Siegelungsdauer 1,1 Sekunden.To produce a water-soluble packaging with the washing or cleaning agent V1, V2 or V3, a film of the type M 8630 (ex Monosol) with a thickness of 76 μm was pulled into a depression by means of a vacuum to form a bulge. The bulge was then filled with 35 g each of the liquid washing or cleaning agent V1, V2 or V3. After covering the bulge filled with the agent V1, V2 or V3 with a second layer of an M 8630 film, the first and second layers were sealed together. The sealing temperature was 150 ° C and the sealing time 1.1 seconds.

Die wasserlösliche Verpackung mit dem Wasch- oder Reinigungsmittel V1 war ästhetisch wenig ansprechend, da sich die während der Herstellung des Wasch- oder Reinigungsmittels V1 gebildeten Präzipitate an der wasserlöslichen Umhüllung festsetzten.The water-soluble packaging with the washing or cleaning agent V1 was aesthetically unattractive, since the precipitates formed during the preparation of the washing or cleaning agent V1 fixed to the water-soluble sheath.

Nach 8 Wochen Lagerzeit der wasserlöslichen Verpackung mit den Wasch- oder Reinigungsmitteln E1 und E2 konnte keinerlei An- oder Auflösung der wasserlöslichen Umhüllung beobachtet werden. Zudem konnten keine Poren oder Löcher, die ebenfalls zum Produktaustritt oder Leckagen führen würden, festgestellt werden. Ferner konnten keinerlei Reaktionen des optischen Aufhellers oder des Farbübertragungsinhibitors mit der wasserlöslichen Umhüllung festgestellt werden.After 8 weeks storage time of the water-soluble packaging with the detergents or cleaning agents E1 and E2, no application or dissolution of the water-soluble coating could be observed. In addition, no pores or holes, which would also lead to product leakage or leaks, were found. Furthermore, no reactions of the optical brightener or the color transfer inhibitor with the water-soluble coating could be detected.

Zur Bestimmung der Farbübertragungsinhibierung wurden Gewebe aus Baumwolle und Polyamid mit je einer wasserlöslichen Verpackung, enthaltend 35 g der Wasch- oder Reinigungsmittel E1 und E2 oder V3 in einer Haushaltswaschmaschine (Miele W 526) in Gegenwart von mit C.I. Direct Orange 39, C.I. Direct Black 22, C.I. Direct Red 83:1 und C.I. Acid Blue 113 gefärbten Geweben bei 60 °C gewaschen. Nach hängender Trocknung und Mangeln der Wäsche wurde die Verfärbung visuell von sechs geschulten Personen mittels der SSR-Skala (Staining Scale Rating) beurteilt (siehe Tabelle 2).

Die Ergebnisse zur Farbübertragungsinhibierung und zum Erhalt des Weißgrads zeigten deutlich, dass durch Einsatz einer wasserlösliche Verpackung mit wenigstens zwei Kammern, die ein erstes flüssiges wasserarmes Wasch- oder Reinigungsmittel mit einem optischen Aufheller und ein zweites flüssiges wasserarmes Wasch- oder Reinigungsmittel einen Farbübertragungsinhibitor in getrennten Kammern enthält, die Vorteile eines Universal-Waschmittels (Erhalt des Weißgrads) und eines Color-Waschmittels (Farbübertragungsinhibierung) in einem Produkt kombiniert werden können. Die Ergebnisse zeigen auch, dass das es nach Austritt der beiden flüssigen Wasch- oder Reinigungsmittel E1 und E2 aus den jeweiligen Kammern in die Waschflotte zu keiner Deaktivierung durch Bildung von Präzipitaten kommt.The color transfer inhibition and whiteness results clearly demonstrated that by employing a water-soluble package having at least two chambers, a first liquid water-poor detergent or cleaner with an optical brightener and a second liquid low-water detergent or detergent a color transfer inhibitor in separate chambers contains the benefits of a universal detergent (maintaining whiteness) and a color detergent (color transfer inhibition) can be combined in one product. The results also show that there is no deactivation by formation of precipitates after exiting the two liquid detergents or cleaning agents E1 and E2 from the respective chambers in the wash liquor.
