Description

Die Erfindung betrifft ein flüssiges Wasch- oder Reinigungsmittel, enthaltend Tensid(e) und eine Cellulose oder ein Cellulosederivat. Die Erfindung betrifft auch Verfahren zur Herstellung des Wasch- oder Reinigungsmittels.The invention relates to a liquid washing or cleaning agent containing surfactant (s) and a cellulose or a cellulose derivative. The invention also relates to processes for the preparation of the washing or cleaning agent.

Zur Erhöhung der Wasch- oder Reinigungsleistung von Wasch- oder Reinigungsmitteln enthalten diese häufig ein oder mehrere Zusatzstoffe. Um beispielsweise ein Wiederaufziehen von vorher losgelöstem Schmutz in feinerer Verteilung (Redeposition) zu verhindern, enthalten Waschmittel so genannte Vergrauungsinhibitoren, wie zum Beispiel Carboxymethylcellulose.To increase the washing or cleaning performance of detergents or cleaners they often contain one or more additives. For example, in order to prevent re-release of previously released soil in finer distribution (redeposition), detergents contain so-called graying inhibitors, such as carboxymethylcellulose.

So beschreibt die EP 054325 A1 ein Waschmittel mit Carboxymethylcellulose als Vergrauungsinhibitor. In GB 729531 A werden Flüssigwaschmittel mit sauren Cellulosesulfaten vorgeschlagen. DE 10 2007 021 793 A1 betrifft Waschmittel, die Tensid, vergrauungsinhibierendes Polysaccharid mit einer Partikelgröße kleiner 100 nm und weitere übliche Inhaltsstoffe umfassen.That's how it describes EP 054325 A1 a detergent with carboxymethylcellulose as a grayness inhibitor. In GB 729531 A Liquid detergents with acidic cellulose sulfates are proposed. DE 10 2007 021 793 A1 relates to detergents comprising surfactant, graying-inhibiting polysaccharide having a particle size of less than 100 nm and other conventional ingredients.

Seit einigen Jahren werden flüssige Wasch- oder Reinigungsmittel vermehrt in transparenten Flaschen angeboten. Aufgrund der geringen Löslichkeit von Carboxymethylcellulose in flüssigen Wasch- oder Reinigungsmittel kommt es bei Einarbeitung von Carboxymethylcellulose in flüssige Wasch- oder Reinigungsmittel zu Trübungen: Dies führt zu einem ästhetisch wenig ansprechenden Produkt, insbesondere wenn es in einer transparenten Flasche angeboten wird.For some years, liquid detergents or cleaners have increasingly been offered in transparent bottles. Due to the low solubility of carboxymethylcellulose in liquid detergents or cleaners, incorporation of carboxymethylcellulose into liquid detergents or cleaners results in turbidity: this leads to an aesthetically less appealing product, especially if it is offered in a transparent bottle.

Ein weiteres Problem ist, dass stabile Dispersionen von Cellulose oder Cellulosederivaten in der Matrix eines Wasch- oder Reinigungsmittels sehr schwer zu erhalten sind.Another problem is that stable dispersions of cellulose or cellulose derivatives in the matrix of a detergent or cleaning agent are very difficult to obtain.

Es ist deshalb eine Aufgabe der Erfindung, ein flüssiges Wasch-oder Reinigungsmittel mit einer Cellulose oder einem Cellulosederivat bereitzustellen, welches stabil und ästhetisch ansprechend ist.It is therefore an object of the invention to provide a liquid washing or cleaning agent with a cellulose or a cellulose derivative which is stable and aesthetically pleasing.

Diese Aufgabe wird gelöst durch ein flüssiges Wasch- oder Reinigungsmittel, enthaltend

  1. (a) 1 bis 70 Gew.-%, bezogen auf das gesamte flüssige Wasch- oder Reinigungsmittel, Tensid(e) und
  2. (b) eine säurebehandelte Cellulose oder ein säurebehandeltes Cellulosederivat, wobei die säurebehandelte Cellulose oder das säurebehandelte Cellulosederivat mit einer Alkylbenzolsulfonsäure behandelt worden sind.
This object is achieved by a liquid washing or cleaning agent containing
  1. (A) 1 to 70 wt .-%, based on the total liquid detergent or cleaning agent, surfactant (s) and
  2. (b) an acid-treated cellulose or an acid-treated cellulose derivative, wherein the acid-treated cellulose or the acid-treated cellulose derivative has been treated with an alkylbenzenesulfonic acid.

Überraschenderweise hat sich gezeigt, dass durch eine Säurebehandlung von Cellulose oder einem Cellulosederivat die Einarbeitbarkeit in eine flüssige Matrix eines Wasch- oder Reinigungsmittel verbessert werden kann, ohne dass die vergrauungsinhibierende Eigenschaft der Cellulose oder des Cellulosederivats verloren geht. Durch die verbesserte Einarbeitbarkeit werden ästhetisch ansprechende flüssige Wasch- oder Reinigungsmittel mit vergrauungsinhibierender Eigenschaft erhalten.Surprisingly, it has been found that the incorporability into a liquid matrix of a washing or cleaning agent can be improved by an acid treatment of cellulose or a cellulose derivative without losing the graying-inhibiting property of the cellulose or of the cellulose derivative. The improved incorporability of aesthetically pleasing liquid detergents or cleaners are obtained with graying-inhibiting property.

Es ist bevorzugt, dass das Mittel ein säurebehandeltes Cellulosederivat ausgewählt aus der Gruppe bestehend aus säurebehandelter Carboxymethylcellulose (CMC), einem säurebehandelten Ethersulfonsäuresalz von Cellulose, einem säurebehandelten sauren Schwefelsäureestersalz von Cellulose, säurebehandelter Methylcellulose, säurebehandelter Ethylcellulose, säurebehandelter Hydroxyethylcellulose, säurebehandelter Hydroxypropylcellulose, säurebehandelter Hydroxypropylmethylcellulose, säurebehandelter Methylhydroxyethylcellulose, säurebehandelter Methylcarboxymethylcellulose, säurebehandelter Ethylhydroxyethylcellulose und einer Mischung dieser säurebehandelten Cellulosederivate enthält.It is preferred that the agent is an acid-treated cellulose derivative selected from the group consisting of acid-treated carboxymethylcellulose (CMC), an acid-treated cellulose acid sulfonic acid ester salt, acid-treated methylcellulose, acid-treated ethylcellulose, acid-treated hydroxyethylcellulose, acid-treated hydroxypropylcellulose, acid-treated hydroxypropylmethylcellulose, acid-treated methylhydroxyethylcellulose, acid-treated methylcarboxymethylcellulose, acid-treated ethylhydroxyethylcellulose and a mixture of these acid-treated cellulose derivatives.

Diese säurebehandelten Cellulosederivate lassen sich besonders stabil und gleichmäßig in die flüssige Matrix eines Wasch- oder Reinigungsmittels einarbeiten.These acid-treated cellulose derivatives can be incorporated in a particularly stable and uniform manner in the liquid matrix of a washing or cleaning agent.

Dabei ist es insbesondere bevorzugt, dass das säurebehandelte Cellulosederivat säurebehandelte Carboxymethylcellulose (CMC) und/oder säurebehandelte Hydroxypropylmethylcellulose ist. Insbesondere bevorzugt ist die säurebehandelte Carboxymethylcellulose säurebehandelte Natriumcarboxymethylcellulose.In this case, it is particularly preferred that the acid-treated cellulose derivative is acid-treated carboxymethylcellulose (CMC) and / or acid-treated hydroxypropylmethylcellulose. Particularly preferred is the acid-treated carboxymethyl cellulose acid-treated sodium carboxymethyl cellulose.

Diese säurebehandelten Cellulosederivate weisen besonders hohe vergrauungsinhibierende Eigenschaften auf und führen nach ihrer Einarbeitung in die flüssige Matrix von Wasch- oder Reinigungsmitteln zu transparenten Produkten ohne Agglomerate, Ausfällungen des Cellulosederivats.These acid-treated cellulose derivatives have particularly high graying-inhibiting properties and, after incorporation into the liquid matrix of detergents or cleaners, lead to transparent products without agglomerates and precipitates of the cellulose derivative.

Es ist bevorzugt, dass die Menge an säurebehandelter Cellulose oder säurebehandeltem Cellulosederivat 0,01 bis 10 Gew.-% und mehr bevorzugt 0,1 bis 8 Gew.-%, jeweils bezogen auf das gesamte flüssige Wasch- oder Reinigungsmittel, beträgt.It is preferred that the amount of acid-treated cellulose or acid-treated cellulose derivative is from 0.01% to 10% by weight, and more preferably from 0.1% to 8% by weight, based on the total liquid detergent or cleaning agent.

Diese Mengen an Cellulose oder Cellulosederivat haben sich als besonders vorteilhaft erwiesen. Unter einer Menge von 0,01 Gew.-% kann kein vergrauungsinhibierender Effekt beobachtet werden und bei Mengen größer 8 Gew.-% kann keine weitere Steigerung der vergrauungsinhibierenden Wirkung des flüssigen Wasch- oder Reinigungsmittels beobachtet werden.These amounts of cellulose or cellulose derivative have proven to be particularly advantageous. At a level of 0.01% by weight, no graying-inhibiting effect can be observed, and at amounts greater than 8% by weight, no further increase in the graying-inhibiting effect of the liquid detergent or cleaning agent can be observed.

Die säurebehandelte Cellulose oder das säurebehandelte Cellulosederivat sind mit einer Alkylbenzolsulfonsäure behandelt worden. Die Salze von Alkylbenzolsulfonsäure sind häufig verwendete anionische Tenside in flüssigen Wasch- oder Reinigungsmitteln. Durch den Einsatz von Alkylbenzolsulfonsäure als Säure in der Säurebehandlung braucht einerseits keine zusätzlich Chemikalie verwendet werden und die säurebehandelte Cellulose oder das säurebehandelte Cellulosederivat kann direkt, dass heißt ohne weitere Aufarbeitung, in der Herstellung des flüssigen Wasch- oder Reinigungsmittels eingesetzt werden. Dies macht die Herstellung des flüssigen Wasch- oder Reinigungsmittels besonders effektiv.The acid-treated cellulose or the acid-treated cellulose derivative has been treated with an alkylbenzene sulfonic acid. The salts of alkylbenzenesulfonic acid are commonly used anionic surfactants in liquid detergents or cleaners. By using alkylbenzenesulfonic acid as the acid in the acid treatment, on the one hand, no additional chemical must be used and the acid-treated cellulose or the acid-treated cellulose derivative can be used directly, ie without further workup, in the preparation of the liquid detergent or cleaning agent be used. This makes the preparation of the liquid detergent or cleaning agent particularly effective.
