Description

Die vorliegende Erfindung betrifft flüssige oder pulverförmige Zubereitungen zum Waschen von Textilien, deren Tenside weitestgehend aus nachwachsenden Rohstoffen hergestellt werden.The present invention relates to liquid or powder preparations for washing Textiles whose surfactants are largely made from renewable raw materials.

Flüssige Waschmittel bestehen heute vor allem aus anionischen Tensiden, insbesondere Alkylbenzolsulfonat, Fettalkoholoxethylat und Seife, wohingegen Waschpulver neben den Tensiden Alkylbenzolsulfonat und Fettalkoholoxethylat als wesentliche Wirkstoffe noch Buildersubstanzen, Bleichmittel und andere Elektrolyte enthalten. Gemeinsam ist flüssigen und pulverförmigen Waschmittelformulierungen, daß als Tenside insbesondere solche auf petrochemischer Basis eingesetzt werden.Liquid detergents today mainly consist of anionic surfactants, especially alkylbenzenesulfonate, Fatty alcohol oxyethylate and soap, whereas washing powder in addition to the surfactants alkyl benzene sulfonate and fatty alcohol oxyethylate as essential active ingredients, builder substances, bleaching agents and other electrolytes contain. Common to liquid and powder detergent formulations is that they are surfactants in particular those based on petrochemicals are used.

Im Hinblick auf die zukünftige Rohstoffsituation (Erdölverknappung) ist diese petrochemische Basis ein erheblicher Nachteil. Ein weiterer Nachteil besteht darin, daß biologische Abbaubarkeit und Ökotoxizität dieser Tenside häufig nicht das entsprechende Niveau von Tensiden auf nativer Basis erreichen.With regard to the future raw material situation (oil shortage) this petrochemical basis is one considerable disadvantage. Another disadvantage is that it is biodegradable and ecotoxic these surfactants often do not reach the corresponding level of surfactants on a native basis.

Aufgabe der Erfindung war es daher, eine Tensidkombination für schwachschäumende Waschmittel zu finden, die weitestgehend aus nachwachsenden Rohstoffen hergestellt werden und die neben sehr guten Waschergebnissen hervorragend biologisch abbaubar sind.The object of the invention was therefore to provide a surfactant combination for low-foaming detergents find that are largely made from renewable raw materials and which are very good Washing results are extremely biodegradable.

Diese Aufgabe wurde gelöst durch eine Tensidkombination, die im wesentlichen aus Alkylpolyglycosiden, Fettalkoholoxethylaten und Seife besteht.This object was achieved by a surfactant combination consisting essentially of alkyl polyglycosides, There is fatty alcohol oxyethylates and soap.

  • 3 to 30% alkyl polyglycoside
  • 3 to 30% fatty alcohol oxyethylate
  • 5 to 30% soap and
  • 0 to 5% other surfactants,
    • which is characterized in that the alkyl polyglycoside is a mixture of 2 components of the formulas I and II RON n R'-O-Z ' m contains in which R is a linear or branched, saturated or unsaturated alkyl radical having 8 to 11 carbon atoms or mixtures thereof, Z n is a polyglycosyl radical with n = 1 to 3 hexose or pentose units or mixtures thereof, R 'is a linear or branched, saturated or unsaturated alkyl radical having 12 to 18 carbon atoms or mixtures thereof and Z ' m is a polyglycosyl radical with m = 1 to 3 hexose or pentose units or mixtures thereof.

    Die Verwendung von einem Alkylpolyglycosid in Kombination mit Fettalkoholoxethylaten und auch mit anionischen Tensiden ist an sich bekannt. So erwähnt bereits die DE-OS 593 422 die wascheffektverstärkende Wirkung von Alkylglycosid bei Seifen. Spätere Schriften wie EP-A 0 075 994, 075 995, 075 996, 094 118 und 317 614 beschreiben den Einsatz von Alkylpolyglycosid in Kombination mit anionischen und/oder nichtionischen Tensiden in Waschmitteln.The use of an alkyl polyglycoside in combination with fatty alcohol oxyethylates and also with anionic surfactants are known per se. For example, DE-OS 593 422 already mentions the wash effect enhancer Effect of alkyl glycoside on soaps. Later publications such as EP-A 0 075 994, 075 995, 075 996, 094 118 and 317 614 describe the use of alkyl polyglycoside in combination with anionic and / or nonionic surfactants in detergents.

    Überraschend wurde nun aber festgestellt, daß die erfindungsgemäße Formulierung mit 2 unterschiedlichen Alkylpolyglycosiden hervorragende Waschergebenisse liefert.Surprisingly, it has now been found that the formulation according to the invention has 2 different Alkyl polyglycosides provide excellent washing results.

    Es wird als Alkylpolyglycosid eine Mischung aus mindestens 2 Komponenten einsetzt, die sich einerseits hinsichtlich der Kettenlänge ihrer Alkylgruppen stark unterscheiden und andererseits in unterschiedlicher Konzentration verwendet werden. Hauptkomponenten sind hierbei Alkylpolyglycoside, deren Alkylgruppen 12 bis 18 Kohlenstoffatome enthalten; Nebenkomponenten sind solche, deren Alkylgruppe 7 bis 11 Kohlenstoffatome enthalten. Erfindungsgemäß in dem o. a. tensidischen Anteil ist ein Gehalt an kurzkettigem Alkylpolyglycosid von 1 bis 10 % und an langkettigem von 2 bis 20 %.As the alkyl polyglycoside, a mixture of at least 2 components is used on the one hand differ greatly in the chain length of their alkyl groups and on the other hand in different Concentration can be used.

RON n in which R represents a linear or branched, saturated or unsaturated aliphatic alkyl radical having 7 to 11 carbon atoms or mixtures thereof and Z n represents a polyglycosyl radical with n = 1.0 to 3 hexose or pentose units or mixtures thereof.

    Bevorzugt werden Alkylpolyglycoside mit Alkylresten mit 8 bis 11 Kohlenstoffatomen sowie einem Polyglycosylrest von n = 1,1 bis 2. Besonders bevorzugt werden Alkylpolyglucoside.Alkyl polyglycosides with alkyl radicals having 8 to 11 carbon atoms and one are preferred Polyglycosyl radical from n = 1.1 to 2. Alkylpolyglucosides are particularly preferred.

    Erfindungsgemäß eingesetzte längerkettige Alkylpolyglycoside genügen der Formel II R'-O-Z'm in der R' für einen linearen oder verzweigten, gesättigten oder ungesättigten aliphatischen Alkylrest mit 12 bis 18 Kohlenstoffatomen oder Gemische davon und Z'm für einen Polyglycosylrest mit n = 1,0 bis 3 Hexose- oder Pentoseeinheiten oder Gemische davon stehen.Longer-chain alkyl polyglycosides used according to the invention satisfy formula II R'-O-Z ' m in which R 'is a linear or branched, saturated or unsaturated aliphatic alkyl radical having 12 to 18 carbon atoms or mixtures thereof and Z' m is a polyglycosyl radical with n = 1.0 to 3 hexose or pentose units or mixtures thereof.

    Bevorzugt werden Alkylpolyglycoside mit Fettalkylresten mit 12 bis 16 Kohlenstoffatomen sowie einem Polyglycosylrest von n = 1,1 bis 2. Besonders bevorzugt werden Alkylpolyglucoside.Alkyl polyglycosides with fatty alkyl radicals having 12 to 16 carbon atoms and one are preferred Polyglycosyl radical from n = 1.1 to 2. Alkylpolyglucosides are particularly preferred.

    Die erfindungsgemäß eingesetzten Alkylpolyglycoside können nach bekannten Verfahren auf Basis nachwachsender Rohstoffe hergestellt werden.The alkyl polyglycosides used according to the invention can be based on known processes renewable raw materials are produced.

    Beispielsweise wird Dextrose in Gegenwart eines sauren Katalysators mit n-Butanol zu Butylpolyglycosidgemischen umgesetzt, welche mit langkettigen Alkoholen ebenfalls in Gegenwart eines sauren Katalysators zu den gewünschten Alkylpolyglycosidgemischen umglycosidiert werden. Oder Dextrose wird unmittelbar mit dem gewünschten langkettigen Alkohol umgesetzt.For example, dextrose is mixed with n-butanol to form butyl polyglycoside mixtures in the presence of an acid catalyst implemented with long-chain alcohols also in the presence of an acid catalyst can be re-glycosidated to the desired alkyl polyglycoside mixtures. Or dextrose becomes immediate implemented with the desired long-chain alcohol.

    Die Struktur der Produkte ist in bestimmten Grenzen variierbar. Der Alkylrest R bzw. R' wird durch die Auswahl des langkettigen Alkohols festgelegt. Günstig aus wirtschaftlichen Gründen sind die großtechnisch zugänglichen Alkohole mit 7 bis 18 C-Atomen, insbesondere native Alkohole aus der Hydrierung von Carbonsäuren bzw. Carbonsäurederivaten. Verwendbar sind auch Ziegleralkohole oder Oxoalkohole.The structure of the products can be varied within certain limits. The alkyl radical R or R 'is by the Long-chain alcohol selection set.

B. nach DE-OS 19 43 689 festgelegt. Im Prinzip können bekanntlich Polysaccharide, z. B. Stärke, Maltodextrine, Dextrose, Galaktose, Mannose, Xylose, etc. eingesetzt werden. Bevorzugt sind die großtechnisch verfügbaren Kohlenhydrate Stärke, Maltodextrine und besonders Dextrose. Da die wirtschaftlich interessanten Alkylpolyglycosidsynthesen nicht regio- und stereoselektiv verlaufen, sind die Alkylpolyglycoside stets Gemische von Oligomeren, die ihrerseits Gemische verschiedener isomerer Formen darstellen. Sie liegen nebeneinander mit α- und β-glycosidischen Bindungen in Pyranose- und Furanoseform vor. Auch die Verknüpfungsstellen zwischen zwei Saccachridresten sind unterschiedlich.The polyglycosyl radicals Z n and Z ' m are determined, on the one hand, by the selection of the carbohydrate and, on the other hand, by setting the average degree of polymerization n or m. B. according to DE-OS 19 43 689. In principle, it is known that polysaccharides, e.g. B. starch, maltodextrins, dextrose, galactose, mannose, xylose, etc. can be used. The industrially available carbohydrates starch, maltodextrins and especially dextrose are preferred. Since the economically interesting alkyl polyglycoside syntheses are not regio- and stereoselective, the alkyl polyglycosides are always mixtures of oligomers, which in turn represent mixtures of different isomeric forms. They exist side by side with α- and β-glycosidic bonds in pyranose and furanose form. The junctions between two Saccachrid residues are also different.

    Erfindungsgemäß eingesetzte Alkylpolyglycoside lassen sich auch durch Abmischen von Alkylpolyglycosiden mit Alkylmonoglycosiden herstellen. Letztere kann man z. B. nach EP-A 0 092 355 mittels polarer Lösemittel, wie Aceton, aus Alkylpolyglycosiden gewinnen bzw. anreichern. Der Glycosidierungsgrad wird zweckmäßigerweise mittels 1H-NMR bestimmt.Alkyl polyglycosides used according to the invention can also be prepared by mixing alkyl polyglycosides with alkyl monoglycosides. The latter can e.g. B. according to EP-A 0 092 355 using polar solvents, such as acetone, from alkyl polyglycosides. The degree of glycosidation is expediently determined by means of 1 H-NMR.

    Die erfindungsgemäßen Waschmittel enthalten 1 bis 10 % kurzkettiges Alkylpolyglycosid, vorzugsweise 2 - 8 %, sowie 2 - 20 % langkettiges Alkylpolyglycosid, vorzugsweise 3 - 15 %, wobei das Verhältnis von kurzkettigem zu langkettigem Anteil 1 : 10 bis 2 : 1, vorzugsweise 2 : 10 bis 1 : 1 beträgt.The detergents according to the invention preferably contain 1 to 10% of short-chain alkyl polyglycoside 2-8%, and 2-20% long-chain alkyl polyglycoside, preferably 3-15%, the ratio of Short-chain to long-chain fraction 1:10 to 2: 1, preferably 2: 10 to 1: 1.

    Im Vergleich zu fast allen anderen in Waschmitteln eingesetzten Tensiden gelten die Alkylpolyglycoside als überaus umweltverträglich. So liegt der mittels Kläranlagen-Simulationsmodell/DOC-Analyse bestimmte biologische Abbaugrad für die erfindungsgemäßen Alkylpolyglycoside bei 96 ± 3 %. Diese Zahl ist vor dem Hintergrund zu sehen, daß bei diesem Testverfahren (Totalabbau) bereits ein Abbaugrad ≧ 70 % die Substanz als gut abbaubar indiziert.Compared to almost all other surfactants used in detergents, the alkyl polyglycosides apply as extremely environmentally friendly. This is how it is determined using the sewage treatment plant simulation model / DOC analysis degree of biodegradation for the alkyl polyglycosides according to the invention at 96 ± 3%. That number is before Background to see that with this test method (total degradation) already a degree of degradation ≧ 70% Substance indicated as readily degradable.

    Auch die akute orale Toxizität LD 50 (Ratte) mit > 10 000 mg/kg sowie die aquatische Toxizität LC 50 (Goldorfe) mit ca. 12 mg/l und EC 50 (Daphnien) mit 30 mg/l liegen um den Faktor 3 bis 5 günstiger als die entsprechenden Werte der heute wichtigsten Tenside. Ähnliches gilt für die Haut- und Schleimhautverträglichkeit.The acute oral toxicity LD 50 (rat) with> 10,000 mg / kg and the aquatic toxicity LC 50 (Gold orfe) with approx. 12 mg / l and EC 50 (daphnia) with 30 mg / l are cheaper by a factor of 3 to 5 than that corresponding values of the most important surfactants today. The same applies to skin and mucous membrane compatibility.
