Description

Die vorliegende Erfindung betrifft ein wäßriges Reinigungsmittel, das nichtionische Tenside enthält und zur Reinigung im Sanitärbereich geeignet ist.The present invention relates to an aqueous cleaning agent, the nonionic Contains surfactants and is suitable for cleaning in the sanitary area.

Bei vielen Reinigungsmitteln, wie z.B. den Sanitär-Reinigern, ist es erwünscht, daß diese viskos sind, um eine längere Einwirkzeit auf nicht-waagerechten Oberflächen zu erreichen. Der pH-Wert saurer Reinigungsmittel liegt üblicherweise zwischen 0 und 2. Ein derart niedriger pH-Wert stellt an die Stabilität der Komponenten besondere Anforderungen. Die zur Erhöhung der Viskosität eingesetzten Verdickungsmittel, z.B. Amine oder Aminderivate, liefern häufig Produkte, die nicht über einen ausreichenden Zeitraum viskositätsstabil sind. Hinzukommt, daß bei diesen Verdickern die Viskosität der Produkte stark in Abhängigkeit von der Lagertemperatur schwanken kann. Andere typische Verdickungsmittel wie Guar-Mehl, Xanthan Gum oder Cellulose-Derivate sind in sauren Medien nicht stabil und verlieren schnell ihre Verdicker-Eigenschaften. Ein weiterer Nachteil dieser Verbindungen ist, daß sie keinen Beitrag zur Reinigungsleistung der Reinigungsmittel leisten.With many cleaning agents, e.g. the sanitary cleaners, it is desirable that these are viscous for a longer exposure time on non-horizontal surfaces to reach. The pH value of acidic cleaning agents is usually between 0 and 2. Such a low pH value makes the stability of the components special Conditions. The thickeners used to increase the viscosity, e.g. Amines, or amine derivatives, often supply products that are not are stable in viscosity over a sufficient period of time. On top of that at these thickeners the viscosity of the products strongly depending on the storage temperature can fluctuate. Other typical thickeners like guar flour, Xanthan gum or cellulose derivatives are not stable and in acidic media quickly lose their thickening properties. Another disadvantage of this Connections is that they do not contribute to the cleaning performance of the Afford detergents.

Die in neutralen und alkalischen Reinigungsmitteln eingesetzten Verdickungsmitteln führen dazu, daß die Reinigungsmittel sich bei einem gegebenenfalls vorgesehenen Verdünnungsvorgang nur schwer in Wasser auflösen. Neben den vorgenannten Verdickungsmitteln ist dieser Nachteil auch bei synthetischen Polymeren zu beobachten.The thickeners used in neutral and alkaline cleaning agents lead to the detergents becoming stuck to an optionally provided one It is difficult to dissolve the dilution process in water. In addition to the aforementioned This disadvantage is also a disadvantage of synthetic polymers in the case of thickeners to observe.

In der DE-OS 23 59 095 werden z.B. nichtionische Tenside, insbesondere tertiäre Amine, als Verdickungsmittel in Sanitär-Reinigern verwendet. Ihre Lagerstabilität ist jedoch nicht ausreichend.In DE-OS 23 59 095 e.g. nonionic surfactants, especially tertiary Amines, used as thickeners in sanitary cleaners. Your storage stability however, is not sufficient.

In der DE-OS 35 42 970 wird ein Sanitär-Reinigungsmittel beschrieben, das als Verdickungsmittel Alkylethersulfate, amphotere Tenside bzw. Mischungen aus nichtionischen Tensiden mit oxethylierten Aminen enthält. In dieser Schrift wird ausgeführt, daß beim Einsatz von nichtionischen Tensiden allein unerwünscht hohe Konzentrationen an Tensiden einzusetzen sind, um eine ausreichende Verdickung zu erreichen.In DE-OS 35 42 970 a sanitary cleaning agent is described as Thickeners alkyl ether sulfates, amphoteric surfactants or mixtures of contains nonionic surfactants with ethoxylated amines. In this writing stated that undesirable when using nonionic surfactants alone high concentrations of surfactants must be used to ensure sufficient thickening to reach.

Aus der EP-A1-0 475 002 ist ein Sanitär-Reinigungsmittel bekannt, das aus 2 bis 40 Gew.-% Säure, 2 bis 10 Gew.-% C10-C18-Fettalkoholethoxylat mit 8 bis 14 EO-Einheiten und 2 bis 10 Gew.-% Verdickungsmittel besteht, worin als Verdickungsmittel ein C10-C18-Fettalkoholethoxylat mit 1 bis 7 EO-Einheiten verwendet wird und der freie Fettalkoholgehalt unter 5 % beträgt. Den Beispielen dieser Druckschrift kann entnommen werden, daß beim Einsatz von höheren Fettalkoholgehalten die Viskosität stark abnimmt. Es ist also erforderlich, die Ausgangsprodukte in hoher Reinheit einzusetzen, was die Kosten dieser Produkte erhöht.EP-A1-0 475 002 discloses a sanitary cleaning agent which consists of 2 to 40% by weight of acid, 2 to 10% by weight of C 10 -C 18 fatty alcohol ethoxylate with 8 to 14 EO units and 2 up to 10% by weight of thickener, in which a C 10 -C 18 fatty alcohol ethoxylate with 1 to 7 EO units is used as the thickener and the free fatty alcohol content is below 5%. The examples in this document show that the viscosity decreases sharply when higher fatty alcohol contents are used. It is therefore necessary to use the starting products in high purity, which increases the costs of these products.

    Die folgenden Beispiele sollen die Erfindung näher erläutern, ohne diese darauf zu beschränken. The following examples are intended to explain the invention in more detail without being directed thereto restrict.

    BeispieleExamples

    Die Reinigungsmittel der folgenden Beispiele wurden durch einfaches Vermischen der Komponenten hergestellt. Die Viskosität der erhaltenen Mittel wurde nach Brookfield mit Spindel 1 bei 20 °C und geeigneter Drehzahl zwischen 10 und 100 Umdrehungen pro Minute (UpM) gemessen. Soweit nichts anderes vermerkt, sind die Gehalte in Gewichtsprozent angegeben.The cleaning agents of the following examples were made by simple mixing of the components. The viscosity of the agents obtained became Brookfield with spindle 1 at 20 ° C and a suitable speed between 10 and 100 Revolutions per minute (rpm) measured. Unless otherwise noted, are the contents are given in percent by weight.
