Description

Es ist bekannt, daß gewisse kationische quartäre Ammoniumverbindungen, wenn man sie im letzten Spülbad der Waschmachine zusetzt, den verschiedenen Gewebearten, wie z.B. Baumwolle, Wolle, Baumwoll-Synthetik-Mischgewebe, einen guten Griff und gleichzeitig antistatische Eigenschaften verleihen. Es bereitet aber gewisse Schwierigkeiten, höher konzentriert eingestellte Formulierungen dieser Wäscheweichspülmittel herzustellen und siegleichmäßig in der kalten Spülflotte zu verteilen, weil bei Zusatz von Weichspülern in Form von 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. Meistens erhält man eine gelartige Mischung, die schwer oder überhaupt nicht mehr in kaltem Wasser dispergierbar ist.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, cotton-synthetic 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. 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 bis 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.Therefore, fabric softeners have so far been generally 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.

Ein weiterer Nachteil ist der hohe an sich überflüssige Wassergehalt dieser Lösungen.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 softeners 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 Wäscheweichspülmittelkonzentrate bestehend aus

  • a) etwa 30 bis 70 vorzugsweise 40 bis 50 Gewichtsprozent eines kationischen Weichmacher's
  • by etwa 5 bis 30, vorzugsweise 3C bis 40 Gewichts prozent eines nichtionischen Weichmachers, der gleichzeitig auch als Dispergiermittel fungiert
  • c) etwa 5 bis 20, vorzugsweise 5 bis 10 Gewichtsprozent eines nichtionischen Dispergiermittels
  • d) etwa 5 bis 30,vorzugsweise 5 bis 10 Gewichtsprozent eines C1-C3-Alkohols, insbesondere Isopropanol
  • e) etwa 5 bis 30 vorzugsweise 5 bis 10 Gewichtsprozent eines flüssigen Glykols, Polyglykols oder deren C1-4-Alkyläther, insbesondere Butyldiglykol, Ethylenglykol oder 1,2-Propandiol und
  • f) Wasser und gegebenenfalls Parfüm und Farbstoffen in Mengen entsprechend dem Ausgleich zu 100 Gewichtsprozent.
The invention thus relates to liquid fabric softener concentrates consisting of
  • a) about 30 to 70, preferably 40 to 50 percent by weight of a cationic plasticizer
  • by about 5 to 30, preferably 3C to 40 weight percent of a nonionic plasticizer, which also acts as a dispersant
  • c) about 5 to 20, preferably 5 to 10 percent by weight of a nonionic dispersant
  • d) about 5 to 30, preferably 5 to 10 percent by weight of a C 1 -C 3 alcohol, in particular isopropanol
  • e) about 5 to 30 preferably 5 to 10 percent by weight of a liquid glycol, polyglycol or their C 1-4 alkyl ether, in particular butyl diglycol, ethylene glycol or 1,2-propanediol and
  • f) water and possibly perfume and dyes in amounts corresponding to the balance to 100 percent by weight.

Als kationische weichmachende Bestandteile der erfindungsgemäßen Wäscheweichspülmittelkonzentrate kommen die für diese Verwendung bekannten, lipophile Reste enthaltenden quartären Ammoniumverbindungen in Betracht, wie sie z.B. in Chemistry and Industry, Juli 1969, Seite 893/894 beschrieben sind, vor allem solche Verbindungen die durch die allgemeinen Formeln I, II und III charakterisiert sind.

In diesen Formeln bedeuten:

  • R1 und R2 Alkyl- oder Alkenylreste mit 8 bis 20 Kohlenstoffatomen, insbesondere Reste der C-Kettenverteilung wie sie in Cocosfettsäurealkyl, Talgfettsäurealkyl, ölsäurealkyl, Spermölfettsäurealkyl vorkommen,
  • R3 Wasserstoff oder einen Alkylrest mit 1 bis 3 Kohlenstoffatomen, insbesondere Wasserstoff oder Methyl, x Zahlen von 1 bis 5 vorzugsweise 1, m und n 2 oder 3, vorzugsweise 2, - A Chlor oder Brom, vorzugsweise Chlor, und Y Chlor oder Methosulfat.
In these formulas:
  • R 1 and R 2 are alkyl or alkenyl radicals with 8 to 20 carbon atoms, in particular radicals of the C chain distribution as they occur in coconut fatty acid alkyl, tallow fatty acid alkyl, oleic acid alkyl, sperm oil fatty acid alkyl,
  • R 3 is hydrogen or an alkyl radical having 1 to 3 carbon atoms, in particular hydrogen or methyl, x numbers from 1 to 5, preferably 1, m and n 2 or 3, preferably 2, A chlorine or bromine, preferably chlorine, and Y chlorine or methosulfate .

Bei der Bereitung der flüssigen Weichspüllmittelkonzentrate gemäß der Erfindung werden diese kationischen weichmachenden Bestandteile zweckmäßig in Form ihrer konzentrierten Lösungen in niederen Alkoholen, vorzugsweise Isopropanol oder im Gemisch dieser Alkohole mit Wasser eingesetzt. Die erfindungsgemäßen Konzentrate enthalten daher eine bestimmte Menge solcher niederen Alkohole.When preparing the liquid fabric softener concentrates according to the invention, these cationic softening components are expediently in the form of their concentrated solutions used in lower alcohols, preferably isopropanol or in a mixture of these alcohols with water. The concentrates according to the invention therefore contain a certain amount of such lower alcohols.

Als weiterer wesentlicher Bestandteil werden Umsetzungsprodukte aus einem Fettsäureethanolamid mit Ethylenoxid der Formel IV

wobei R4 Alkyl- oder Alkenylreste mit 8-22, vorzugsweise 8-16 Kohlenstoffatomen, R3 Wasserstoff oder einen Alkylrest mit 1-3 Kohlenstoffatomen, insbesondere Wasserstoff oder Methyl,A further essential component are reaction products from a fatty acid ethanolamide with ethylene oxide of the formula IV

p eine Zahl von 1 bis 5, vorzugsweise 2 und Y eine Zahl von 1 bis 15, vorzugsweise 5-8, bedeuten, als nichtionische Dispergatoren eingesetzt. Dabei ist es wesentlich, daß es sich hier um eine stickstoffhaltige Substanz handelt, die einen pseudo-kationischen Charakter aufweist. Für sich allein ist die Substantivität dieses Verbindungstyps auf Gewebe zu schwach ausgeprägt. In Kombination mit einer quartären Ammoniumverbindung der Formeln I - III zieht die erwähnte nichtionische Verbindung aber auf die Wäsche auf und verleiht der Faser einen zusätzlichen weichen Griff. Gleichzeitig wirken diese nichtionischen Weichmachertypen auch als Dispergatoren oder Emulgatoren.p is a number from 1 to 5, preferably 2 and Y is a number from 1 to 15, preferably 5-8, used as nonionic dispersants. It is essential that this is a nitrogenous substance that has a pseudo-cationic character. As such, the substantivity of this type of compound on tissue is too weak. In combination with a quaternary ammonium compound of the formulas I - III, the non-ionic compound mentioned is absorbed onto the laundry and gives the fiber an additional soft feel. At the same time, these nonionic types of plasticizers also act as dispersants or emulsifiers.

Ein weiterer Bestandteil der Wäscheweichspülmittelkonzentrate gemäß der Erfindung sind übliche nichtionische Dispergatoren oder Emulgatoren auf der Basis von Oxalkylaten, die mit dazu beitragen, daß das Konzentrat 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 Umsetzungsprodukte 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.Another component of the fabric softener concentrates according to the invention are customary nonionic dispersants or emulsifiers based on oxalkylates, which contribute to the fact that the concentrate is readily dispersible in cold water. Suitable nonionic dispersants are, for example, reaction products of in each case about 2-12 mol of ethylene oxide with an alkylphenol, such as xylenol, but also with an alkylphenol with a long alkyl radical of 8-10 carbon atoms or with a fatty alcohol with 8 to 15 carbon atoms, in particular reaction products of about 5 to 8 mol of EO with 1 mol of alkylphenol or 1 mol of a fatty alcohol containing 8 to 15 carbon atoms or a mixture of such fatty alcohols.

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

Die Einsatzmenge der erfindungsgemäßen Wäscheweichspülmittelkonzentrate beträgt etwa 10-20 q auf 4 kg Wäsche. Dies entspricht hinsichtlich der weichmachenden Wirkung einer Menge von etwa 50 bis 100 ml eines handelsüblichen Wäscheweichspülmittels mit 5 % WS.The amount of the fabric softener concentrate according to the invention is about 10-20 q per 4 kg of laundry. In terms of the softening effect, this corresponds to an amount of about 50 to 100 ml of a commercially available fabric softener with 5% WS.

Die erfindungsgemäßen Wäscheweichspülmittelkonzentrate, 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 nunmehr in der erfindungsgemäßen konzentrierten Form und nicht mehr wie bisher als verdünnte wäßriqe Lösunqen aehandelt werden können. Dadurch entfällt die Notwendigkeit, auf allen Stufen des Handels größere, letzten Endes überflüssige Mengen Wasser transportieren zu müssen.The laundry fabric softener concentrates according to the invention, which have good softening properties, can be dispersed well in cold water without causing troublesome gel formation. 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 softening agents can now be treated in the concentrated form according to the invention and no longer as diluted aqueous solutions as before. This eliminates the need for all levels of the trade having to transport larger, ultimately unnecessary amounts of water.
