Description

Es ist bekannt, daß gewisse kationische quartäre Ammoniumverbindungen, wenn man sie im letzten Spülbad der Waschmaschine zusetzt, den verschiedenen Gewebearten, wie z.B. Baumwolle, Wolle, Baumwollsynthetik-Mischgewebe, einen guten Griff und gleichzeitig antistatische Eigenschaften verleihen. Es bereitet aber gewisse Schwierigkeiten, höher konzentriert eingestellte Formulierungen dieser Wäscheweichspülmittel herzustellen und sie gleichmäßig in der kalten Spülflotte zu verteilen, weil bei Zusatz von Weichspülern in Form vom konzentrierten wäßrigen oder alkoholischen Lösungen gallertartige Ausscheidungen auftreten, die zur Bildung von Flecken auf der Wäsche führen können. Auch die Verdünnung eines solchen Konzentrates auf eine handelsübliche 2 - 5 %ige Formulierung bereitet Schwierigkeiten.It is known that certain cationic quaternary ammonium compounds, when added in the final rinse of the washing machine, can be used in various types of fabrics, e.g. Cotton, wool, synthetic cotton blend, give a good grip and at the same time antistatic properties. However, there are certain difficulties in producing formulations of these fabric softening agents with a higher concentration and distributing them evenly in the cold washing liquor, because when softeners are added in the form of concentrated aqueous or alcoholic solutions, gelatinous precipitates occur which can lead to the formation of stains on the laundry . It is also difficult to dilute such a concentrate to a commercially available 2-5% formulation.

Meistens erhält man eine gelartige Mischung, die schwer oder überhaupt nicht mehr in kaltem Wasser dispergierbar ist.Usually a gel-like mixture is obtained which is difficult or impossible to disperse in cold water.

Wäscheweichspülmittel werden deshalb bisher allgemein in Form von verdünnten, etwa 2 - 10 %igen wäßrigen Lösungen, verwendet. Diese verdünnten Lösungen weisen jedoch verschiedene Nachteile auf. Sie können z.B. nicht kalt gelagert werden, da sie nach dem Einfrieren und Wiederauftauen eine Gelkonsistenz annehmen und nicht mehr in homogene Lösung gebracht werden können. Ein weiterer Nachteil ist der hohe an sich überflüssige Wassergehalt dieser Lösungen.For this reason, fabric softeners have so far generally been used in the form of dilute, about 2 to 10% aqueous solutions. However, these diluted solutions have several disadvantages. You can e.g. should not be stored cold, because after freezing and thawing, they assume a gel consistency and can no longer be brought into homogeneous solution. Another disadvantage is the high excess water content of these solutions.

Es wurde nun gefunden, daß es gelingt, flüssige konzentrierte Zubereitungen von Wäscheweichspülmitteln herzustellen, die diese Nachteile der verdünnten Lösungen nicht aufweisen, und die sich auch in kaltem Spülwasser- leicht verteilen.It has now been found that it is possible to produce liquid, concentrated preparations of fabric softening agents which do not have these disadvantages of the dilute solutions and which are readily distributed even in cold rinse water.

Gegenstand der Erfindung sind somit flüssige Wäscheweichspülmittel bestehend aus einer wäßrigen Lösung oder Dispersion von Verbindungen der Formel 1

worin R1 methylverzweigtes Alkyl oder Alkenyl mit jeweils 12 - 30, vorzugsweise 14 bis 18 C-Atomen, R2 C1-C4-Alkyl und A ein Anion bedeutet sowie gegebenenfalls weiteren Hilfsstoffen.The invention thus relates to liquid fabric softeners consisting of an aqueous solution or dispersion of compounds of the formula 1

 in which R 1 is methyl-branched alkyl or alkenyl each having 12-30, preferably 14 to 18, carbon atoms, R 2 C 1 -C 4 -alkyl and A is an anion and optionally further auxiliaries.

Die quartären Ammoniumverbindungen der obigen Formel werden erhalten nach üblichen Verfahren ausgehend von methylverzweigten Fettsäuren. Aus diesen Säuren stellt man mit Ammoniak das Amid und daraus das Nitril her, das durch Hydrieren in das Di-alkylamin überführt wird. Dieses Di-alkylamin wird dann nach bekannten Verfahren alkyliert und quaterniert. Bei den methylverzweigten Alkyl- bzw. Alkenylresten handelt es sich um Isomeren-Gemische mit unterschiedlicher Position der Methylgruppe. Als Anion A kommt vorzugsweise ein Chlorid-, Methosulfat-, Ethosulfat-, Methophosphat- oder Ethophosphation in Frage. Als R2 ist Methyl bevorzugt.The quaternary ammonium compounds of the above formula are obtained by conventional methods starting from methyl-branched fatty acids. From these acids, the amide and therefrom the nitrile are produced with ammonia, which is converted into the di-alkylamine by hydrogenation. This di-alkylamine is then alkylated and quaternized by known methods. The methyl-branched alkyl or alkenyl radicals are isomer mixtures with different positions of the methyl group. Anion A is preferably a chloride, methosulfate, ethosulfate, methophosphate or ethophosphate ion. Methyl is preferred as R 2 .

Bei der Bereitung der flüssigen Weichspülmittel gemäß der Erfindung werden diese kationischen weichmachenden Verbindungen zweckmäßig in Form ihrer konzentrierten Lösungen in niederen Alkoholen, vorzugsweise Isopropanol oder im Gemisch dieser Alkohole mit Wasser eingesetzt. Die erfindungsgemäßen Wäscheweichspülmittel enthalten in diesem Fall eine bestimmte Menge solcher niederen Alkohole (ca. 5 - 30 Gew.-%).When preparing the liquid fabric softener according to the invention, these cationic softening compounds are expediently used in the form of their concentrated solutions in lower alcohols, preferably isopropanol or in a mixture of these alcohols with water. In this case, the fabric softening agents according to the invention contain a certain amount of such lower alcohols (approx. 5-30% by weight).

Ein weiterer Bestandteil der Wäscheweichspülmittel gemäß der Erfindung können übliche nichtionische Dispergatoren oder Emulgatoren sein auf Basis von Oxalkylaten, die mit dazu beitragen, daß das Wäscheweichspülmittel in kaltem Wasser gut dispergierbar ist. Geeignete nichtionische Dispergatoren sind z.B. Umsetzungsprodukte von jeweils etwa 2 - 12 Mol Ethylenoxid mit einem Alkylphenol wie z.B. Xylenol, aber auch mit einem Alkylphenol mit einem langen Alkylrest von 8 - 10 C-Atomen oder mit einem Fettalkohol mit 8 bis 15 C-Atomen, insbesondere Umsetzungprcdukte von etwa 5 bis 8 Mol EO mit 1 Mol Alkylphenol oder 1 Mol eines 8 bis 15 C-Atome enthaltenden Fettalkohols oder eines Gemisches solcher Fettalkohole. Die Menge dieser nichtionischen Verbindungen beträgt 3 bis 10 Gew.-% bei schwach konzentrierten Wäscheweichspülmitteln mit einem Gehalt der Verbindungen der Formel 1 von .ca. 10 bis 30 Gew.-%. Höher konzentrierte Wäscheweichspülmittel mit einem Gehalt der Verbindungen der Formel 1 von ca. 30 bis 70 Gew.-% enthalten vorzugsweise 5 bis 20 Gew.-% der nichtionischen Dispergiermittel. Bei den verdünnten, handelsüblichen Wäscheweichspülmittelnn ist die Zugabe von solchen Dispergiermitteln nicht nötig.Another constituent of the fabric softener according to the invention can be customary nonionic dispersants or emulsifiers based on oxalkylates, which contribute to the fact that the fabric softener is readily dispersible in cold water. Suitable nonionic dispersants are e.g. Reaction products of about 2-12 moles of ethylene oxide each with an alkylphenol such as e.g. Xylenol, but also with an alkylphenol with a long alkyl radical of 8-10 C atoms or with a fatty alcohol with 8 to 15 C atoms, in particular reaction products of about 5 to 8 moles of EO with 1 mole of alkylphenol or 1 mole of an 8 to 15 C-containing fatty alcohol or a mixture of such fatty alcohols. The amount of these nonionic compounds is 3 to 10 wt .-% in weakly concentrated fabric softeners with a content of the compounds of formula 1 of .ca. 10 to 30% by weight. Highly concentrated fabric softeners with a content of the compounds of formula 1 of approximately 30 to 70% by weight preferably contain 5 to 20% by weight of the nonionic dispersant. With the diluted, commercially available fabric softeners, it is not necessary to add such dispersants.

Solche höher konzentrierten Wäscheweichspülmittel enthalten darüberhinaus vorzugsweise noch 5 bis 30 Gew.-% eines Ethylenglykols, Prcpylenglykols, Polyethylenglykols, Polypropylenglykols sowie die C1-C4-Alkylether dieser Verbindungen. Es versteht sich, daß von dieser Produktgruppe nur solche Verbindungen in Frage kommen, die flüssig sind. Diese Verbindungen zeigen in den erfindungsgemäßen Wäscheweichspülmitteln eine lösungsvermittelnde Wirkung.Such more highly concentrated fabric softeners also preferably contain 5 to 30% by weight of an ethylene glycol, prepylene glycol, polyethylene glycol, polypropylene glycol and the C 1 -C 4 -alkyl ethers of these compounds. It goes without saying that only compounds of this product group that are liquid are suitable. These compounds have a solubilizing effect in the fabric softeners according to the invention.

Die Herstellung der erfindungsgemäßen Wäscheweichspülmittel kann durch einfaches Vermischen der Komponenten oder ihrer konzentrierten Lösungen geschehen. Gegebenenfalls können auch Parfüm, Farbstoff, optische Aufhellungsmittel oder sonstige Hilfsstoffe zugesetzt werden. Zur Einstellung der gewünschten Endkonzentration wird gegebenenfalls noch mit der hierfür notwendigen Menge Wasser verdünnt. Die Mengen der einzelnen Komponenten werden innerhalb der angegebenen Grenzen so gewählt, daß das fertige Mittel, einschließlich eventuell zusätzlicher Mengen an Wasser, Parfüm und Farbstoffen, 100 Gew.-% ergibt.The fabric softener according to the invention can be produced by simply mixing the components or their concentrated solutions. If necessary, perfume, dye, optical brighteners or other auxiliaries can also be added. To set the desired final concentration, it may be diluted with the necessary amount of water. The amounts of the individual components are selected within the limits specified so that the finished composition, including any additional amounts of water, perfume and colorants, is 100% by weight.

Die Einsatzmenge der erfindungsgemäßen Wäscheweichspülmittel beträgt, bezogen auf eine Waschmaschinenfüllung Wäsche (ca. 4 kg) 80 bis 150 ml, 30 bis 70 ml bzw. 10 bis 20 ml für ein Weichspülmittel mit einem Gehalt einer Verbindung der Formel 1 von 2 bis 10 Gew.-% 10 bis 30 Gew.-% bzw. 30 bis 70 Gew.-%.The amount of the fabric softener according to the invention, based on a washing machine load of laundry (approx. 4 kg), is 80 to 150 ml, 30 to 70 ml or 10 to 20 ml for a fabric softener with a compound of formula 1 of 2 to 10% by weight. -% 10 to 30 wt .-% or 30 to 70 wt .-%.

Die erfindungsgemäßen Wäscheweichspülmittel, die gute weichmachende Eigenschaften aufweisen, lassen sich in kaltem Wasser gut dispergieren, ohne daß es. zu einer störenden Gelbildung kommt. Hierbei ist es von Vorteil, daß diese Konzentrate mit geeigneten Dosiervorrichtungen direkt in Haushaltsmaschinen eingegeben werden können. Diese gute Löslichkeit erlaubt es auch, die erfindungsgemäßen Konzentrate erst kurz vor ihrer Eingabe in die Waschmaschine zu verdünnen, so daß die Wäscheweichspülmittel auch in konzentrierter Form und nicht nur als verdünnte wäßrige Lösungen gehandelt werden können. Dadurch entfällt die Notwendigkeit, auf allen Stufen des Handels größere, letzten Endes überflüssige Mengen Wasser transportieren zu müssen.The fabric softeners according to the invention, which have good softening properties, can be dispersed well in cold water without it. disruptive gel formation occurs. It is advantageous here that these concentrates can be fed directly into household machines with suitable metering devices. This good solubility also allows the concentrates according to the invention to be diluted shortly before they are put into the washing machine, so that the fabric softener can also be traded in concentrated form and not only as dilute aqueous solutions. This eliminates the need to transport large, ultimately superfluous amounts of water at all stages of the trade.

Beispielexample a) Herstellung von Diisostearylamina) Preparation of diisostearylamine

400 g Isostearylamin werden in einem Rührkolben mit Thermometer und Gaseinleitungsrohr mit 20 g Raney-Nickel versetzt und 100 1 Wasserstoff/Stunde eingegast. Die Reaktionstemperatur wird in ca. 30 Minuten auf 160°C gebracht und 1,5 Stunden gehalten. Nach Abkühlen auf ca. 50°C wird der Katalysator abfiltriert und dabei Diisostearylamin in praktisch quantitativer Ausbeute erhalten. Das Reaktionsprodukt enthält neben 92,3 % Sekundär-Anteilen 4,7 % bzw. 3 % Primär- und Tertiär-Aminanteile.400 g of isostearylamine are mixed in a stirred flask with a thermometer and gas inlet tube with 20 g of Raney nickel and gassed with 100 l of hydrogen / hour. The reaction temperature is brought to 160 ° C. in about 30 minutes and held for 1.5 hours.

b) Herstellung von Diisostearyldimethylammoniumchloridb) Preparation of diisostearyldimethylammonium chloride

126 g Diisostearylamin und 25 g 50 %ige NaOH werden zusammen mit 100 g Isopropanol in einem 1 1-Glasautoklaven mit 28 g flüssigem Methylchlorid analog 1 c umgesetzt. Dabei entsteht ein Methylchlorid-Druck von ca. 5 bar. Nach ca. 2 Stunden Reaktionszeit wird 1 g 50 %ige NaOH nachgegeben und weitere 1,5 Stunden bei 80°C umgesetzt.126 g of diisostearylamine and 25 g of 50% NaOH are reacted together with 100 g of isopropanol in a 1 liter glass autoclave with 28 g of liquid methyl chloride analogously to 1 c. This creates a methyl chloride pressure of approx. 5 bar. After a reaction time of about 2 hours, 1 g of 50% NaOH is added and the reaction is continued at 80 ° C. for a further 1.5 hours.

Nach Entspannen des überschüssigen Methylchlorids wird der pH-Wert der Reaktionsmischung auf 6 - 7 eingestellt und der Rest an Methylchlcrid am Rctationsverdampfer entfernt. Nach Absaugen des ausgefällten NaCl und Zugabe von 8 g Wasser und 15 g Isopropanol werden ca. 150 g Diisostearyldimethylammoniumchlorid 75 %ig in Isopropanol-Wasser (1:2) erhalten.After the excess methyl chloride has been let down, the pH of the reaction mixture is adjusted to 6-7 and the remainder of the methyl chloride is removed on the reaction evaporator. After the precipitated NaCl has been suctioned off and 8 g of water and 15 g of isopropanol have been added, approximately 150 g of 75% strength diisostearyldimethylammonium chloride in isopropanol / water (1: 2) are obtained.
