Abstract
Description
"Flüssige Tensidkonzentrate" Die Erfindung betrifft flüssige Tensidkonzentrate auf der Basis von konzentrierten wäßrigen Lösungen anionischer oberflächenaktiver Stoffe."Liquid Surfactant Concentrates" The invention relates to liquid surfactant concentrates based on concentrated aqueous solutions of anionic surface-active Fabrics.
Für die Reinigung von Textilien sowie für das manuelle Spülen von Geschirr lassen sich flüssige Tensidkonzentrate verwenden, die aus wäßrigen Lösungen von meist anionischen oberflächenaktiven Stoffen bestehen. Mit Rücksicht auf die Verpackung und den Transport ist man bestrebt, zu möglichst konzentrierten Lösungen derartiger Mittel zu gelangen. Entsprechende Bemühungen haben jedoch häufig zu unbefriedigenden Ergebnissen geführt, da während der Lagerung der Konzentrate vielfach Trübungen, Niederschläge oder Phasentrenuen auftreten. Darüberhinaus werden irreversible Entmischungsvorgänge insbesondere dann beobachtet, wenn die Konzentrate zeitweilig bei Temperaturen in der Nähe des Gefrierpunktes gelagert werden.For cleaning textiles and for manually rinsing Dishes can be used with liquid surfactant concentrates made from aqueous solutions consist of mostly anionic surfactants. With consideration for the Packaging and transport strives to be as concentrated as possible such means to arrive. However, such efforts are often unsatisfactory Results because during the storage of the concentrates there was often turbidity, Precipitation or phase renuities occur. In addition, there are irreversible segregation processes observed in particular when the concentrates are temporarily used at temperatures in be stored near freezing point.
Es gibt eine Reihe von bekannten Maßnahmen mit dem Ziel, derartige nachteilige Erscheinungen auszuschalten. So hat man flüssigen Tensidkombinationen bereits verschiedene organische Lösungsmittel zugesetzt. Daneben wurden hydrotrope Substanzen, wie Alkalisalze von Arylsulfonsäuren oder Harnstoff, als Lösungsvermittler verwendet. Die bisher erzielten Ergebnisse waren jedoch nicht in jeder Hinsicht zufriedenstellend.There are a number of known measures aimed at achieving such to eliminate adverse phenomena. So you have liquid surfactant combinations various organic solvents already added. In addition, were hydrotropes Substances such as alkali salts of aryl sulfonic acids or urea as solubilizers used. The results achieved so far, however, have not been in all respects satisfactory.
Gegenüber diesen bekannten Maßnahmen ermöglicht die Erfindung eine wesentliche Verbesserung der Eigenschaften vJEßriger Tensidkonzentrate auf der Basis anionischer oberflächenaktiver Stoffe. Diese Verbesserung erstreckt sich nicht nur auf die Löslichkeit und Lagerbeständigkeit der Konzentrate, sondern sie bringt auch eine Verstärkung der Reinigungswirkung mit sich.Compared to these known measures, the invention enables a substantial improvement in the properties of aqueous surfactant concentrates based on anionic surfactants. This improvement doesn't just extend on the solubility and shelf life of the concentrates, but it also brings about an intensification of the cleaning effect with it.
Gegenstand der Erfindung sind flüssige Tensidkonzentrate für die Textil- und Geschirreinigung auf der Basis von anionischen oberflächenaktiven Stoffen mit einem Tensidgehalt von 10 bis 60 Gewichtsprozent und einem Wasseranteil von mindestens 25 Gewichtsprozent, die gekennzeichnet sind durch einen Gehalt von 1 bis 30 Gewichtsprozent an Fettalkoholen der Kettenlängen C8 bis C1. Insbesondere weisen Octanol, Nonanol, Decanol, Undecanol und Dodecanol eine gute hydrotrope Wirkung und eine erhöhte Reinigungswirkung in Geschirrspülmitteln auf.The invention relates to liquid surfactant concentrates for textile and dish cleaning based on anionic surfactants with a surfactant content of 10 to 60 percent by weight and a water content of at least 25 percent by weight, which is characterized by a content of 1 to 30 percent by weight of fatty alcohols of chain lengths C8 to C1. In particular, octanol, nonanol, Decanol, undecanol and dodecanol have a good hydrotropic effect and an increased cleaning effect in dishwashing detergents.
Als anionische grenzenflächenaktive Stoffe enthalten die flüssigen Tensidkonzetrate Alkylsulfonate, Olefinsulfonate, K-Sulfofettsäureester oder Alkylsulfate, insbesondere aber Alkylbenzolsulfonate, Alkyläthersulfate oder Alkylpolyäthersulfate mit Alkylresten von 8 bis 18 C-Atomen. Der Anteil der Tenside an den Konzentraten betrugt 10 bis 60 Gewichtsprozent, vorzugsweise 20 bis 45 Gewichtsprozent, während der Anteil der Fettalkohole 1 bis 30 Gewichtsprozent, vorzugsweise 3 bis 20 Gewichtsprozent ausmacht. Das Verhältnis Tensid : Fettalkohol liegt vorzugsweise bei 1 : 0,1 bis 1 : 0,3. Der Fettalkoholzusatz bewirkt eine Erhöhung der Viskosität der Konzentrate, was in vielen Fällen erwünscht ist.The liquid ones contain surface-active substances as anionic Surfactant concentrates, alkyl sulfonates, olefin sulfonates, K sulfo fatty acid esters or alkyl sulfates, but in particular alkylbenzenesulfonates, alkyl ether sulfates or alkyl polyether sulfates with alkyl radicals of 8 to 18 carbon atoms. The proportion of surfactants in the concentrates was 10 to 60 percent by weight, preferably 20 to 45 percent by weight, while the proportion of fatty alcohols is 1 to 30 percent by weight, preferably 3 to 20 percent by weight matters. The surfactant: fatty alcohol ratio is preferably 1: 0.1 to 1: 0.3. The addition of fatty alcohol causes an increase in the viscosity of the concentrates, which is desirable in many cases.
Den Tensidkonzentraten können gewünschtenfalls weitere übliche Zusätze zugegeben werden, wie beispielsweise Konservierungs- und Desinfektionsmittel, Parfümöle, Farbstoffe, Hautschutzmittel und dergleichen.If desired, further customary additives can be added to the surfactant concentrates added, such as preservatives and disinfectants, perfume oils, Dyes, skin protectants and the like.
Die beanspruchten Tensidkonzentrate werden bevorzugt zum anellen Spülen von Geschirr verwendet. Sie werden den ;einigungsflotten in Mengen von etwa 0,05 bis 5 g/l, vorzugsweise 0,5 bis 2 g/l, bezogen auf das konzentrierte flüssige Mittel, zugesetzt. Die Produkte besitzen eine hervorragende Lagerstabilität und entmischen sich auch dann nicht, wenn sie längere Zeit-bei Temperaturen in der ähe des Gefrierpunktes aufbewahrt werden. Besonders vorteilhaft wirkt sich der Fettalkoholzusatz auf die Reinigungswirkung der anionischen Tenside aus, die erheblich gesteigert wird. Infolge der löslichkeitsverbessernden Wirkung lassen sich auch relativ schwerlösliche Tenside5 wie Fettalkoholsulfate höherer Kettenlängen in beständige wäßrige Konzentrate überführen. So ermöglicht die Erfindung beispielsweise die Verwendung von Natrium-Fettalkoholsulfat-Gemischen der Kettenlängen C12 18 in flüssigen Geschirrspülmittelkonzentraten.The claimed surfactant concentrates are preferred for regular rinsing used by dishes. They are used in the cleaning liquors in quantities of about 0.05 up to 5 g / l, preferably 0.5 to 2 g / l, based on the concentrated liquid agent, added. The products have excellent storage stability and segregate Not even if they are used for a long time-at temperatures close to freezing point be kept. The addition of fatty alcohol has a particularly beneficial effect on the The cleaning effect of the anionic surfactants, which is significantly increased. As a result Relatively sparingly soluble surfactants5 can also be used to improve solubility how fatty alcohol sulfates of higher chain lengths are converted into stable aqueous concentrates. For example, the invention enables the use of sodium fatty alcohol sulfate mixtures of chain lengths C12 18 in liquid dishwashing detergent concentrates.
