Description

Feuchttücher (III)Wet wipes (III)
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 hard surface cleaners and relates to wet wipes impregnated with a particular species of nonionic surfactant.
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 Pa- tentanmeldung 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 also tissue papers that are soaked with a cleaning liquid. For example, in 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 Durchsat- zes 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 Ver- dünnen 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. It is disadvantageous 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. Another The 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 Mischether, vorzugsweise in Kombination mit Alkyloligoglucosiden die komplexe Aufgabe in ausgezeichneter Weise erfüllen. Imprägniermittel auf Basis von Mischethem erweisen sich in der An- meidung als niedrigviskos und praktisch schaumfrei, in der Anwendung hinterlassen die damit getränkten Feuchttücher keine Streifen und beeinträchtigen den Glanz nicht. Konzentrate auf Basis der Mischether sind niedrigviskos und beim Verdünnen auf die Anwendungskonzentration besonders schaumarm.Surprisingly, it was found that nonionic surfactants of the mixed ether type, preferably in combination with alkyl oligoglucosides, perform the complex task in an excellent manner.

Concentrates based on mixed ethers are low-viscosity and particularly low-foaming when diluted to the application concentration.

in der R3 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-AI 0301298 und WO 90/03977 verwiesen.in which R 3 is an alkyl and / or alkenyl radical having 4 to 22 carbon atoms, G is a sugar radical having 5 or 6 carbon atoms and p is a number from 1 to 10.

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 aligemeinen 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 above all 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 in particular between 1.2 and 1.4.

Beispiele 1 bis 4, Vergleichsbeispiel VI. Verschiedene Imprägnierlösungen wurden durch einfaches Vermischen der Komponenten hergestellt; anschließend wurde das Schaumvermögen der Mischungen unter dynamischen Bedingungen nach der Frei-Fall-Kreislauf- Methode (1 Gew.-% Waschaktivsubstanz, 25 °C, Förderrate 1 l/min) bestimmt. Zur Prüfung der Reinigungsleistung sowie der Glanzerhaltung wurden die Zubereitungen auf einen saugfähigen Träger (saugfähiges Tissuepapier, dreilagig, Gewicht 18 g/m2, 95 Gew.-% Recy- dingpapieranteil) aufgetragen. Zur Bestimmung des Reinigungsvermögens auf harten und elastischen Oberflächen wurde ein mit Testschmutz behandelter weißer Schmutzträger unter definierten Bedingungen mit den imprägnierten Tüchern gewischt. Der Reinigungseffekt wurde dabei photoelektrisch gegen den unbehandelten Schmutzträger (Standard = 100 %) gemessen. Zur Überprüfung der Glanzerhaltung wurde eine hochglänzende schwarze Kachel mit den imprägnierten Tüchern gereinigt und die Differenz mit Hilfe eines Glanzmeßgerätes (unbehandelter Standard = 100 %) bestimmt. Das Tauchnetzvermögen wurde schließlich gemäß DIN EN 1772 (0,1 Gew.-% Aktivsubstanz, 20 °C) gemessen.

Die Beispiele 1 bis 4 sind erfindungsgemäß, Beispiel VI dient zum Vergleich.Examples 1 to 4, Comparative Example VI. Various impregnation solutions were made by simply mixing the components; the foaming power of the mixtures was then determined under dynamic conditions using the free-fall cycle method (1% by weight of washing-active substance, 25 ° C., delivery rate 1 l / min). To check the cleaning performance and the maintenance of gloss, the preparations were applied to an absorbent carrier (absorbent tissue paper, three layers, weight 18 g / m2, 95% by weight recycled paper portion). To determine the cleaning ability on hard and elastic surfaces, a white dirt carrier treated with test dirt was wiped with the impregnated cloths under defined conditions. The cleaning effect was measured photoelectrically against the untreated dirt carrier (standard = 100%). To check gloss maintenance, a high-gloss black tile was cleaned with the impregnated cloths and the difference was determined using a gloss meter (untreated standard = 100%). The immersion wetting power was finally measured in accordance with DIN EN 1772 (0.1% by weight of active substance, 20 ° C.).
