Description

Gebiet der ErfindungField of the Invention

Die Erfindung befindet sich auf dem Gebiet der Reinigungsmittel für harte Oberflächen und betrifft Feuchttücher, die mit einer speziellen Spezies eines nichtionischen Tensids imprägniert sind.The invention is in the field of cleaning agents for hard surfaces and relates to wet wipes impregnated with a special species of a nonionic surfactant are.

Stand der TechnikState of the art

Für die Reinigung von harten Oberflächen werden in der Regel mehr oder weniger viskose Flüssigkeiten eingesetzt, die direkt aufgetragen werden, von der zu reinigenden Fläche ablaufen und dabei die Hauptmenge des Schmutzes mittragen. Eine andere Anwendungsform, die sich zunehmender Bedeutung erfreut, sind Feuchttücher, sogenannte "wet wipes", bei denen es sich um textile Gewebe oder aber auch Tissuepapiere handelt, welche mit einer Reinigungsflüssigkeit getränkt sind. So werden beispielsweise in der internationalen Patentanmeldung WO 95/35411 (Procter & Gamble) Feuchttücher - wenn auch vorwiegend für kosmetische Anwendungen - vorgeschlagen, welche neben Mineralöl, Fettsäureester, Fettalkoholethoxylate und Fettalkohole enthalten.For the cleaning of hard surfaces, more or less viscous liquids are generally used, which are applied directly, run off the surface to be cleaned and thereby carry most of the dirt. Another form of application that is becoming increasingly important is wet wipes, so-called "wet wipes", which are textile fabrics or tissue papers that are soaked in a cleaning liquid. For example, in the international patent application WO 95/35411 (Procter & Gamble) wet wipes - albeit primarily for cosmetic applications - are proposed which contain mineral oil, fatty acid esters, fatty alcohol ethoxylates and fatty alcohols.

Nachteilig bei der Anwendung dieser wet wipes ist indes, dass die eingesetzten Tenside in Form von Schlieren einen Rückstand hinterlassen, der die behandelte Fläche weniger glänzend oder sogar verschmutzt erscheinen läßt. Ein weiteres Problem tritt bei der Herstellung der Feuchttücher auf. Um das Gewebe oder Tissuepapier mit der Reinigungslösung zu tränken, wird es entweder mit ihr besprüht oder in sie eingetaucht, wobei es in beiden Fällen durch Schaumbildung oder eine zu geringe Benetzung zu einer Verminderung des Durchsatzes in der Produktion kommen kann. Eine erste Aufgabe der vorliegenden Erfindung hat somit darin bestanden, Feuchttücher unter Verwendung spezieller Tenside zur Verfügung zu stellen, welche frei sind von den eingangs geschilderten Problemen.
Aus logistischen Gründen ist die Verwendung von Konzentraten zur Herstellung der Imprägnierlösungen für die Feuchttücher vorteilhaft. Nachteilig ist, dass die Konzentrate beim Verdünnen vielfach die Tendenz zur Schaumbildung zeigen. Außerdem kann es zur Ausbildung von Gelphasen kommen, was zu einem erhöhten Zeitaufwand bei der Herstellung der Tranklösungen führt. In beiden Fällen wird der Durchsatz in der Produktion reduziert. Eine weitere Aufgabe der Erfindung hat somit darin bestanden, Tenside zur Verfügung zu stellen, mit deren Hilfe Konzentrate hergestellt werden können, die durch ihre Viskosität, Lagerstabilität, Schaumarmut beim Verdünnen und rasche Verdünnbarkeit eine technisch einfache und daher kostengünstige Herstellung der Feuchttücher gestattet.A disadvantage of using these wet wipes, however, is that the surfactants used leave a residue in the form of streaks, which makes the treated surface appear less shiny or even dirty. Another problem arises in the manufacture of the wet wipes. In order to impregnate the tissue or tissue paper with the cleaning solution, it is either sprayed with it or immersed in it. In both cases, production throughput can be reduced due to foaming or insufficient wetting. A first object of the present invention was therefore to provide wet wipes using special surfactants which are free from the problems described at the outset.
For logistical reasons, the use of concentrates for the preparation of the impregnation solutions for the wet wipes is advantageous. The disadvantage is that the concentrates often show a tendency to foam when diluted. In addition, gel phases can form, which leads to an increased expenditure of time in the preparation of the potion solutions. In both cases, throughput in production is reduced. A further object of the invention was therefore to provide surfactants which can be used to produce concentrates which, due to their viscosity, storage stability, low foaming when diluted and rapid dilutability, permit technically simple and therefore inexpensive production of the wet wipes.

Überraschenderweise wurde gefunden, dass nichtionische Tenside vom Typ der Hydroxymischether, vorzugsweise in Kombination mit Alkyloligoglucosiden die komplexe Aufgabe in ausgezeichneter Weise erfüllen. Imprägniermittel auf Basis von Hydroxymischether erweisen sich in der Anmeldung als niedrigviskos und praktisch schaumfrei, in der Anwendung hinterlassen die damit getränkten Feuchttücher keine Streifen und beeinträchtigen den Glanz nicht. Konzentrate auf Basis der Hydroxymischether sind niedrigviskos und beim Verdünnen auf die Anwendungskonzentration besonders schaumarm.Surprisingly, it was found that nonionic surfactants of the hydroxy mixed ether type, preferably in combination with alkyl oligoglucosides the complex task in excellent way to meet. Impregnating agents based on hydroxy mixed ether prove leave themselves in the application as low viscosity and practically foam-free, in the application the wet wipes soaked with it do not have streaks and impair the shine Not. Concentrates based on hydroxy mixed ethers are low-viscosity and when diluted low foaming to the application concentration.

Alkyl- und/oder AlkenyloligoglykosideAlkyl and / or alkenyl oligoglycosides

Anwendungstechnische Untersuchungen zeigen, dass Mischungen von Hydroxymischethem und Alkyl- und/oder Alkenyloligoglykosiden besonders vorteilhaft sind. Bei letzteren handelt es sich um bekannte nichtionische Tenside dar, die der Formel (II) folgen, R5O-[G]p   (II) in der R5 für einen Alkyl- und/oder Alkenylrest mit 4 bis 22 Kohlenstoffatomen, G für einen Zuckerrest mit 5 oder 6 Kohlenstoffatomen und p für Zahlen von 1 bis 10 steht Sie können nach den einschlägigen Verfahren der präparativen organischen Chemie erhalten werden. Stellvertretend für das umfangreiche Schrifttum sei hier auf die Schriften EP-A1 0301298 und WO 90/03977 verwiesen.Application studies show that mixtures of hydroxy mixed ethers and alkyl and / or alkenyl oligoglycosides are particularly advantageous. The latter are known nonionic surfactants which follow the formula (II) R 5 O- [G] p (II) in which R 5 represents an alkyl and / or alkenyl radical having 4 to 22 carbon atoms, G represents a sugar radical having 5 or 6 carbon atoms and p represents numbers from 1 to 10. They can be obtained by the relevant preparative organic chemistry processes. As a representative of the extensive literature, reference is made here to the documents EP-A1 0301298 and WO 90/03977 .

Die Alkyl- und/oder Alkenyloligoglykoside können sich von Aldosen bzw. Ketosen mit 5 oder 6 Kohlenstoffatomen, vorzugsweise der Glucose ableiten. Die bevorzugten Alkyl- und/oder Alkenyloligoglykoside sind somit Alkyl- und/oder Alkenyloligoglucoside. Die Indexzahl p in der allgemeinen Formel (II) gibt den Oligomerisierungsgrad (DP), d. h. die Verteilung von Mono- und Oligoglykosiden an und steht für eine Zahl zwischen 1 und 10. Während p in einer gegebenen Verbindung stets ganzzahlig sein muß und hier vor allem die Werte p = 1 bis 6 annehmen kann, ist der Wert p für ein bestimmtes Alkyloligoglykosid eine analytisch ermittelte rechnerische Größe, die meistens eine gebrochene Zahl darstellt. Vorzugsweise werden Alkyl- und/oder Alkenyloligoglykoside mit einem mittleren Oligomerisierungsgrad p von 1,1 bis 3,0 eingesetzt. Aus anwendungstechnischer Sicht sind solche Alkyl- und/oder Alkenyloligoglykoside bevorzugt, deren Oligomerisierungsgrad kleiner als 1,7 ist und insbesondere zwischen 1,2 und 1,4 liegt. The alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (II) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While p in a given compound must always be an integer, and especially here can assume the values p = 1 to 6, the value p for a certain alkyl oligoglycoside is an analytically determined arithmetic parameter, which usually represents a fractional number. Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, preference is given to those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and is in particular between 1.2 and 1.4.

Der Alkyl- bzw. Alkenylrest R5 kann sich von primären Alkoholen mit 4 bis 11, vorzugsweise 8 bis 10 Kohlenstoffatomen ableiten. Typische Beispiele sind Butanol, Capronalkohol, Caprylalkohol, Caprinalkohol und Undecylalkohol sowie deren technische Mischungen, wie sie beispielsweise bei der Hydrierung von technischen Fettsäuremethylestem oder im Verlauf der Hydrierung von Aldehyden aus der Roelen'schen Oxosynthese erhalten werden.

Typical examples are butanol, capronic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis.
