Stand der TechnikState of the art

An Mittel zur Reinigung harter Oberflächen, wie beispielsweise Geschirrspülmittel oder Universalreiniger, wird vom Verbraucher eine Vielzahl von Anforderungen gestellt: so müssen die Mittel selbstverständlich eine ausreichende Reinigungskraft besitzen, auch in Gegenwart von Wasserhärte und Ölbelastung schäumen, eine ausreichende hohe Viskosität besitzen, so daß sie sich leicht dosieren lassen und auch an vertikalen Flächen nicht sofort abfließen; schließlich müssen sie trotz der geforderten ausgeprägten Detergenseigenschaften gleichzeitig noch eine besondere Hautverträglichkeit besitzen.On agents for cleaning hard surfaces, such as dishwashing detergents or universal cleaners, the consumer places a multitude of requirements: the means must be self-evident have sufficient cleaning power, even in the presence of water hardness and oil pollution foam, have a sufficiently high viscosity so that they can be easily metered and also do not drain off immediately on vertical surfaces; after all, despite the required pronounced detergent properties also have a special skin tolerance.

Mittel, die für diese Aufgaben in Betracht kommen, enthalten vielfach Kombinationen von Alkylglucosiden und Fettalkoholethersulfaten, gegebenenfalls in Abmischung mit amphoteren Tensiden vom Betaintyp. So sind z.B. aus der internationalen Patentanmeldung WO 94/09102 (Henkel) wäßrige Tensidkonzentrate bekannt, die 5 bis 20 Gew.-% Alkylglucoside, 25 bis 40 Gew.-% Fettalkoholsulfate, 35 bis 65 Gew.-% Fettalkoholethersulfate und 5 bis 20 Gew.-% amphotere Tenside enthalten, wobei letztere sich von Fettaminen bzw. Fettsäureamidoaminen ableiten, die eine C-Kettenverteilung im Bereich von 6 bis 22 aufweisen. Geschirrspülmittel mit einem Gehalt an diesen Stoffen sind auch aus der internationalen Patentanmeldung WO 91/11506 (Henkel) bekannt. Über Synergieeffekte zwischen Alkylglucosiden, Betainen und Ethersulfaten berichten H.Leidreiter und U.Maczkiewitz in SÖFW-Journal 122, 674 (1996). Agents that are suitable for these tasks often contain combinations of alkyl glucosides and fatty alcohol ether sulfates, optionally in a mixture with amphoteric surfactants of the betaine type. For example, from international patent application WO 94/09102 (Henkel) aqueous surfactant concentrates are known which contain 5 to 20% by weight alkyl glucosides, 25 to 40% by weight fatty alcohol sulfates, 35 to 65% by weight fatty alcohol ether sulfates and 5 to 20% by weight .-% contain amphoteric surfactants, the latter being derived from fatty amines or fatty acid amidoamines which have a C chain distribution in the range from 6 to 22.

Die Aufgabe der vorliegenden Erfindung hat darin bestanden, derartige Mittel zur Verfügung zu stellen.Nevertheless, there is a constant need in the market for preparations that differ from the state of the art Technology have further improved application properties.

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 (V) 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. 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 Fettsäuremethylestern oder im Verlauf der Hydrierung von Aldehyden aus der Roelen'schen Oxosynthese erhalten werden. Bevorzugt sind Alkyloligoglucoside der Kettenlänge C8-C10 (DP = 1 bis 3), die als Vorlauf bei der destillativen Auftrennung von technischem C8-C18-Kokosfettalkohol anfallen und mit einem Anteil von weniger als 6 Gew.-% C12-Alkohol verunreinigt sein können sowie Alkyloligoglucoside auf Basis technischer C9/11-Oxoalkohole (DP = 1 bis 3). Der Alkyl- bzw. Alkenylrest R5 kann sich ferner auch von primären Alkoholen mit 12 bis 22, vorzugsweise 12 bis 14 Kohlenstoffatomen ableiten. Typische Beispiele sind Laurylalkohol, Myristylalkohol, Cetylalkohol, Palmoleylalkohol, Stearylalkohol, Isostearylalkohol, Oleylalkohol, Elaidylalkohol, Petroselinylalkohol, Arachylalkohol, Gadoleylalkohol, Behenylalkohol, Erucylalkohol, Brassidylalkohol sowie deren technische Gemische, die wie oben beschrieben erhalten werden können. Bevorzugt sind Alkyloligoglucoside auf Basis von gehärtetem C12/14-Kokosalkohol mit einem DP von 1 bis 3.Alkyl and alkenyl oligoglycosides which form component (b) are known nonionic surfactants which follow the formula (III) ,

    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 methods of preparative organic chemistry, for example by acid-catalyzed acetalization of glucose with fatty alcohols. 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 oligo glucosides . The index number p in the general formula (V) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While p must always be an integer in a given compound 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 in particular between 1.2 and 1.4. The alkyl or alkenyl radical R 5 can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capro 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. Alkyl oligoglucosides of chain length C 8 -C 10 (DP = 1 to 3) are preferred, which are obtained as a preliminary step in the separation of technical C 8 -C 18 coconut fatty alcohol by distillation and with a proportion of less than 6% by weight of C 12 - Alcohol can be contaminated and alkyl oligoglucosides based on technical C 9/11 oxo alcohols (DP = 1 to 3). The alkyl or alkenyl radical R 5 can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and their technical mixtures, which can be obtained as described above. Alkyl oligoglucosides based on hardened C 12/14 coconut alcohol with a DP of 1 to 3 are preferred.
