Description
Stabilisierte Reinigungsmittel Stabilized detergents
Die vorliegende Erfindung betrifft ein flüssiges Reinigungsmittel, vorzugsweise ein flüssiges Geschirrspülmittel, besonders bevorzugt ein flüssiges Handgeschirrspülmittel, das ein The present invention relates to a liquid detergent, preferably a liquid dishwashing detergent, more preferably a liquid hand dishwashing detergent, a
Tensidsystem enthält, umfassend mindestens ein Betain, mindestens ein Alkylethersulfat und mindestens ein Aminoxid, wobei das Reinigungsmittel durch dieses Tensidsystem stabilisiert wird. Ferner richtet sich die vorliegende Erfindung auf die Verwendung des Tensidsystems zur A surfactant system comprising at least one betaine, at least one alkyl ether sulfate and at least one amine oxide, wherein the cleaning agent is stabilized by this surfactant system. Furthermore, the present invention is directed to the use of the surfactant system
Stabilisierung der Viskosität des erfindungsgemäßen Mittels bei höheren Temperaturen sowie auf die Verwendung des flüssigen Reinigungsmittels zur Reinigung von harten Oberflächen. Stabilization of the viscosity of the composition according to the invention at higher temperatures and to the use of the liquid detergent for cleaning hard surfaces.
Schließlich richtet sich die vorliegende Erfindung auf ein Verfahren zur Reinigung von harten Oberflächen, wobei das erfindungsgemäße Reinigungsmittel angewendet wird. Finally, the present invention is directed to a method for cleaning hard surfaces, wherein the cleaning agent according to the invention is applied.
Herkömmliche flüssige Reinigungsmittel weisen signifikante Unterschiede in der Viskosität bei unterschiedlichen Temperaturen auf. Bei etablierten Reinigungsmittel nimmt die Viskosität bei erhöhten Temperaturen merklich ab. Dies ist sowohl bei der Herstellung als auch bei der Conventional liquid cleaners have significant differences in viscosity at different temperatures. For established detergents, the viscosity decreases markedly at elevated temperatures. This is both in the production as well as in the
Verwendung des Reinigungsmittels nachteilig, da bereits geringe Temperaturänderungen die Dosierung und die Pumpfähigkeit des Mittels beeinflussen. Bei erhöhter Temperatur kann das Mittel von den zu behandelnden Oberflächen fließen, bevor das Mittel angewendet werden kann. Ferner müssen bei der Herstellung des Mittels die Abfüllanlagen je nach Temperatur nachjustiert werden, um eine konstante Pumpleistung zu erzielen. Use of the detergent disadvantageous, since even small temperature changes affect the dosage and pumpability of the agent. At elevated temperature, the agent may flow from the surfaces to be treated before the agent can be applied. Furthermore, in the preparation of the agent, the filling systems must be readjusted depending on the temperature in order to achieve a constant pumping power.
Bislang in flüssigen Reinigungsmitteln eingesetzte Viskositätsregulatoren sind insbesondere beim Einsatz bei Temperaturextremen problematisch, die in Haushalten in unterschiedlichen Klimazonen durchaus auftreten können. Natriumchlorid kann beispielsweise bei Temperaturen um 20°C zur Einstellung einer höheren Viskosität eingesetzt werden. Steigt die Temperatur jedoch auf 35°C an, kann eine Formulierung, die bei 20°C noch eine Viskosität von 5500 mPas aufwies, plötzlich eine Viskosität von unter 1200 mPas aufweisen. Bei Temperaturen deutlich unter 20°C nimmt die Viskosität dagegen stark zu. Verwendet man dagegen Verdicker auf Polymer- oder Cellulosebasis, so zeigen diese zwar eine weniger ausgeprägte Viskositätsveränderung in Abhängigkeit von der Temperatur, aber auch ihr Viskositätsprofil zeigt hohe Werte bei tiefen Temperaturen und niedrige Werte bei hohen Temperaturen. Zudem sind diese Verdicker in der Verarbeitung aufwendig und mitunter auch kostspielig, so dass ihr Einsatz nicht immer wünschenswert erscheint.
Die Aufgabe der vorliegenden Erfindung bestand daher darin, Mittel bereitzustellen, vorzugsweise flüssige Geschirrspülmittel, besonders bevorzugt flüssige Handgeschirrspülmittel, die die bekannten Nachteile überwinden, indem sie über einen weiten Temperaturbereich eine weitgehend gleichbleibende Viskosität aufweisen, um so die Abfüllung und Anwendung des Mittels zu verbessern. Previously used in liquid detergents viscosity regulators are particularly problematic when used at temperature extremes that may well occur in households in different climates. For example, sodium chloride can be used at temperatures around 20 ° C to set a higher viscosity. However, if the temperature increases to 35 ° C., a formulation which still has a viscosity of 5500 mPas at 20 ° C. may suddenly have a viscosity of less than 1200 mPas. At temperatures well below 20 ° C, however, the viscosity increases sharply. On the other hand, if thickeners based on polymers or cellulose are used, they exhibit a less pronounced change in viscosity as a function of the temperature, but also their viscosity profile shows high values at low temperatures and low values at high temperatures. In addition, these thickeners are complex in processing and sometimes costly, so that their use is not always desirable. The object of the present invention was therefore to provide means, preferably liquid dishwashing detergents, more preferably liquid hand dishwashing detergents, which overcome the known disadvantages by having a substantially constant viscosity over a wide temperature range so as to improve the filling and application of the agent.
Diese der vorliegenden Erfindung zugrunde liegende Aufgabe wird nun dadurch gelöst, dass das flüssige Reinigungsmittel ein Tensidsystem enthält, das a) 1 bis 15 Gew.-%, vorzugsweise 1 ,5 bis 10 Gew.-%, besonders bevorzugt 1 ,5 bis 5 Gew.-%, insbesondere 2 bis 3,6 Gew.-% mindestens eines Betains, b) 3 bis 25 Gew.-%, vorzugsweise 4 bis 22 Gew.-%, besonderes bevorzugt 5 bis 20 Gew.-%, insbesondere 6 bis 10,9 Gew.-% mindestens eines Alkylethersulfats und c) 1 bis 10 Gew.-%, vorzugsweise 1 bis 6 Gew.-%, besonders bevorzugt 1 bis 5 Gew.-%, insbesondere 1 ,2 bis 2,4 Gew.-% mindestens eines Aminoxids umfasst, jeweils bezogen auf das Gesamtgewicht des Mittels. This object of the present invention is based on the fact that the liquid cleaning agent contains a surfactant system which a) 1 to 15 wt .-%, preferably 1, 5 to 10 wt .-%, particularly preferably 1, 5 to 5 wt .-%, in particular 2 to 3.6 wt .-% of at least one betaine, b) 3 to 25 wt .-%, preferably 4 to 22 wt .-%, particularly preferably 5 to 20 wt .-%, in particular 6 to 10.9 wt .-% of at least one Alkylethersulfats and c) 1 to 10 wt .-%, preferably 1 to 6 wt .-%, particularly preferably 1 to 5 wt .-%, in particular 1, 2 to 2.4 wt. % of at least one amine oxide, in each case based on the total weight of the composition.
Mit Hilfe der vorliegenden Erfindung kann die Viskosität der erfindungsgemäßen flüssigen Mittel über einen breiten Temperaturbereich stabilisiert werden. Abweichend vom üblichen With the aid of the present invention, the viscosity of the liquid agents according to the invention can be stabilized over a wide temperature range. Notwithstanding the usual
Viskositätsverhalten tensidhaltiger Zusammensetzungen bleibt die Viskosität mit steigender Temperatur nahezu gleich oder steigt sogar an. Insbesondere ist auch bei niedrigen Temperaturen, etwa bei 10°C, die Viskosität niedrig, und auch bei hohen Temperaturen, etwa bei 40°C, bleibt der Wert ausreichend hoch. Viscosity behavior of surfactant-containing compositions, the viscosity remains almost the same as the temperature rises or even increases. In particular, even at low temperatures, such as at 10 ° C, the viscosity is low, and even at high temperatures, such as 40 ° C, the value remains sufficiently high.

Other suitable ingredients will be described in detail below.
„Flüssig", wie hierin verwendet, meint den Aggregatzustand und bedeutet, dass die "Liquid" as used herein means the state of matter and means that the

Insbesondere kann sie aber auch für ein inverses Viskositätsverhalten stehen, wobei die Viskosität beispielsweise über den Temperaturbereich von 10 bis 40°C zunimmt, anstatt, wie bei den meisten flüssigen Zusammensetzungen üblich, zu sinken. Stabilization may mean, for example, a reduction in viscosity at 35 ° C compared to 20 ° of less than 70%, preferably less than 60%, more preferably less than 50%, such as a change from 5500 mPas (at 20 °) to 3000 mPas (at 35 ° C).
