Abstract
Description
Die Erfindung betrifft ein Verfahren zur Erhöhung der Viskosität von relativ niedrig konzentrierten wässrigen Textilweichmacher-Dispersionen auf Basis kationischer Weichmacher vom Typ der quartären Ammoniumverbindungen mit wenigstens zwei langen Alkyl-, Alkenyl- oder Acylgruppen durch Zusatz von relativ kleinen Mengen von Alkyl- oder Alkenyl-sulfat-Salzen oder von Alkyl- oder Alkenyl-Ethersulfat-Salzen mit 12-22 C-Atomen in der Alkyloder Alkenylgruppe.The invention relates to a method for increasing the viscosity of relatively low-concentration aqueous textile plasticizer dispersions based on cationic plasticizers of the quaternary ammonium compound type with at least two long alkyl, alkenyl or acyl groups by adding relatively small amounts of alkyl or alkenyl sulfate Salts or of alkyl or alkenyl ether sulfate salts with 12-22 carbon atoms in the alkyl or alkenyl group.
Die in Textilnachspülmitteln gebräuchlichen Textilweichmacher vom Typ der quartären Ammoniumverbindungen mit wenigstens zwei langkettigen Alkyloder Acylgruppen sind in Wasser wenig löslich und liegen daher auch im Bereich niedriger Konzentrationen von weniger als z. B. 10 Gew.-% in Wasser als Dispersion vor. Diese Dispersionen haben die Eigenschaft, daß sie zwar bei höheren Konzentrationen von mehr als 15 gew.-% in Wasser sehr hochviskos und wenig fließfähig sind, im Bereich niedriger Konzentrationen unter 10 Gew.-%, also in den für Haushalts-Wäscheweichmacher üblichen Konzentrationsbereich aber sind diese Disper-sionen sehr dünnflüssig. Dies ist von Nachteil für die Lagerstabilität der Dispersionen und erschwert auch die Handhabung und Dosierung solcher Produkte. Eine Verdickung durch Zusatz bekannter wasserlöslicher Polymerisate wäre zwar möglich, solche Polymeren haben jedoch Nachteile in ihrer Wirkung auf das weichzumachende Textilgewebe und auch in Bezug auf ihre biologische Abbaubarkeit.The fabric softeners of the type of quaternary ammonium compounds with at least two long-chain alkyl or acyl groups which are customary in fabric rinsing agents are not very soluble in water and are therefore also in the range of low concentrations of less than z. B. 10 wt .-% in water as a dispersion. These dispersions have the property that, although they are very highly viscous and poorly flowable in water at higher concentrations of more than 15% by weight, they are below 10% by weight in the range of low concentrations, ie in the concentration range customary for household laundry softeners these dispersions are very thin. This is disadvantageous for the storage stability of the dispersions and also complicates the handling and metering of such products. Thickening by the addition of known water-soluble polymers would be possible, but such polymers have disadvantages in their effect on the textile fabric to be softened and also in their biodegradability.
Es bestand daher die Aufgabe, wässrige Textilweichmacher-Zubereitungen auf Basis quartärer Ammoniumverbindungen durch geeignete, biologisch abbaubare Zusatzstoffe zu verdicken.The task was therefore to thicken aqueous textile plasticizer preparations based on quaternary ammonium compounds by means of suitable, biodegradable additives.
Aus DE-24 32 296 B2 war bekannt, daß Alkylethersulfate die Viskosität wässriger Zubereitungen von Fettsäure-alkanolamin-Kondensaten erniedrigen.From DE-24 32 296 B2 it was known that alkyl ether sulfates make the viscosity more aqueous Reduce preparations of fatty acid alkanolamine condensates.
Aus GB-A-2 054 635 sind Waschmittel-Zusammensetzungen mit einem Zusatz von kationischen Tensiden und Alkylethersulfaten bekannt, in denen ein Alkylethersulfat in einer Menge von 1 - 3 Gewichtsteilen pro Gewichtsteil kationischer Tenside sowie bis zu 50 Gew.-% weitere anionische, amphotere oder nichtionische Tenside enthalten sind.GB-A-2 054 635 discloses detergent compositions with the addition of cationic surfactants and alkyl ether sulfates, in which an alkyl ether sulfate in an amount of 1-3 parts by weight per part by weight of cationic surfactants and up to 50% by weight of further anionic, amphoteric or nonionic surfactants are included.
Überraschend wurde festgestellt, daß Zusätze von Alkylsulfat-Salzen und Alkyl-Ethersulfatsalzen zu Dispersionen von Textilweichmachem des Typs der quartären Ammoniumverbindungen deren Viskosität erhöhen.Surprisingly, it was found that additions of alkyl sulfate salts and alkyl ether sulfate salts to dispersions of textile plasticizers of the quaternary ammonium compound type increase their viscosity.
Obwohl diese verdickende Wirkung der Zusätze von Alkylsulfat-Salzen und Alkyl-Ethersulfat-Salzen in wäßrigen Zubereitungen mit niedriger Konzentration von etwa 0,1 - 10 Gew.-% des dispergierten kationischen Weichmachers besonders wünschenswert ist, stellt man auch bei höherkonzentrierten Textilweichmacher-Dispersionen mit bis zu 40 Gew.-% des dispergierten kationischen Weichmachers eine stabilisierende Wirkung dieses Zusatzes fest.Although this thickening effect of the additions of alkyl sulfate salts and alkyl ether sulfate salts is particularly desirable in aqueous preparations with a low concentration of about 0.1-10% by weight of the dispersed cationic plasticizer, the same is also done with higher-concentration textile plasticizer dispersions up to 40 wt .-% of the dispersed cationic plasticizer a stabilizing effect of this additive.
Es wurde darüber hinaus beobachtet, daß Zusätze von Alkylsulfat-Salzen zu kationischen Textilweichmachem den damit nachbehandelten Textilien eine gewisse schmutzabweisende Ausrüstung verleihen, so daß die danach erfolgenden Anschmutzungen leichter und vollständiger ausgewaschen werden können.It has also been observed that additions of alkyl sulfate salts to cationic textile softeners give the textiles aftertreated with a certain dirt-repellent finish, so that the soiling that follows can be washed out more easily and completely.
Gegenstand der Erfindung sind daher wässrige Textilweichmacher-Zusammensetzungen, dieThe invention therefore relates to aqueous textile plasticizer compositions which
Das Gewichtsverhältnis von kationischem Weichmacher (A) und Alkyl- oder Alkenylsulfat-Salz bzw. Alkyl- oder Alkenylethersulfat-Salz (B) sollte dabei größer als (A) : (B) = 5:1 sein.The weight ratio of cationic plasticizer (A) and alkyl or alkenyl sulfate salt or alkyl or alkenyl ether sulfate salt (B) should be greater than (A): (B) = 5: 1.
Die erfindungsgemäßen Textilweichmacher-Zusammensetzungen weisen eine deutlich erhöhte Viskosität auf, ohne daß in dem erfindungsgemäßen Bereich die Fließfähigkeit der Zubereitungen ungünstig beeinflußt wird. Auch wiesen die erfindungsgemäßen Wäschweichmacher-Dispersionen eine gute Scherstabilität auf. Durch Scherbeanpruchung, wie sie z. B. durch längeranhaltendes Pumpen der Dispersion erfolgt oder durch Lagerung der Dispersionen kommt es zwar noch zu geringfügigen Viskositätszunahmen, insgesamt zeigen die erfindungsgemäßen Weichspüler-Dispersionen jedoch eine hohe Lagerstabilität und ein gutes Anwendungsverhalten.The textile plasticizer compositions according to the invention have a significantly increased viscosity without the flowability of the preparations being adversely affected in the range according to the invention. The laundry plasticizer dispersions according to the invention also had good shear stability. By shear stress as z. B. by prolonged pumping of the dispersion or storage of the dispersions, there are still slight increases in viscosity, but overall, the fabric softener dispersions according to the invention show high storage stability and good application behavior.
Als dispergierte kationische Weichmacher vom Typ der quartären Ammoniumverbindungen (QAV) eignen sich alle hierfür bekannten QAV mit wenigstens zwei langkettigen Alkyl-, Alkenyl- oder Acylgruppen. Beispiele solcher Verbindungen sind z. B. das Distearyl-dimethyl-ammonium-chlorid oder das 1-Methyl-(1-stearoylamino)-ethyl-2-heptadecyl-imidazolinium-methosulfat. Besonders bevorzugt sind erfindungsgemäße Textilweichmacher-Zusammensetzungen, die als QAV eine Verbindung der Formel I
Als Komponente (B) eignen sich die Schwefelsäuremonoester-Salze von Fettalkoholen mit 12-22 C-Atomen oder von Ethylenoxid-Addukten von 1-6 Mol Ethylenoxid an solche Fettalkohole. Als Fettalkohole eignen such hierfür synthetische, auch geringfügig methylverzweigte, gesättigte primäre Alkohole wie sie z. B. durch Hydroformylierung aus Alpha-Olefinen oder durch Ziegler-Aufbausynthese aus Ethylen zugänglich sind. Bevorzugt geeignet sind aber die Sulfatsalze und Ethersulfatsalze von gesättigter und ungesättigten natürlichen Fettalkoholen, wie sie durch Hydrierverfahren aus entsprechenden Fettsäureestern erhältlich sind z. B. auch technische Fettalkoholschnitte, wie sie aus Kokos- oder Talgfettsäure-estern hergestellt werden. Die Alkylsulfate und Alkylethersulfate sollen als wasserlösliche Salze, bevorzugt als Alkali-, Magnesium- oder Ammoniumsalze, vorliegen.Suitable components (B) are the sulfuric acid monoester salts of fatty alcohols with 12-22 carbon atoms or of ethylene oxide adducts of 1-6 mol ethylene oxide with such fatty alcohols. Suitable fatty alcohols for this purpose are synthetic, also slightly methyl-branched, saturated primary alcohols such as, for. B. are accessible by hydroformylation from alpha-olefins or by Ziegler synthesis from ethylene. However, preference is given to the sulfate salts and ether sulfate salts of saturated and unsaturated natural fatty alcohols, as can be obtained by hydrogenation processes from corresponding fatty acid esters, e.g. B. also technical fatty alcohol cuts, such as those made from coconut or tallow fatty acid esters. The alkyl sulfates and alkyl ether sulfates should be present as water-soluble salts, preferably as alkali, magnesium or ammonium salts.
Es hat sich gezeigt, daß die Verdickung der erfindungsgemäßen Textilweichmacher-Zusammensetzung noch weiter gesteigert werden kann, wenn zusätzlich.It has been shown that the thickening of the fabric softening composition according to the invention can be increased even further, if in addition.
bezogen auf die gesamte Dispersion zugesetzt wird. Durch diesen Zusatz von Diol, Polyol oder Polyglycol wird vor allem die Viskositätsstabilität gegenüber Scherbeanspruchungen erheblich verbessert, so daß auch bei der technischen Handhabung der Produkte, z. B. beim Rühren, Pumpen und Fördern keine gravierenden Viskositätsschwankungen auftreten.based on the total dispersion is added. This addition of diol, polyol or polyglycol, especially the viscosity stability against shear stresses is significantly improved, so that also in the technical handling of the products, for. B. when stirring, pumping and conveying no serious viscosity fluctuations occur.
Geeignete Diole sind z. B. Ethylenglycol, 1,2-Propylenglycol, 1,3-Propylenglycol, 1,3-Butandiol; geeignete Polyole sind z. B. Glycerin, Erythrit, Pentaerythrit, Trimethylolpropan und Sorbit, geeignete Polyalkylenglycole z. B. Polyethylenglycole mit Molekulargewichten bis 10 000, insbesondere von 200 bis 1 000.Suitable diols are e.g. B. ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,3-butanediol; suitable polyols are e.g. As glycerol, erythritol, pentaerythritol, trimethylolpropane and sorbitol, suitable polyalkylene glycols such. B. polyethylene glycols with molecular weights up to 10,000, in particular from 200 to 1,000.
Eine bevorzugte Ausführungsform der erfindungsgemäßen Textilweichmacher-Zusammensetzung enthält
- (A) 1 - 10 Gew.-% des kationischen Weichmachers
- (B) 0,1 - 2 Gew.-% eines Alkyl- oder Alkenylsulfat-Alkali-, Magnesiumoder Ammoniumsalzes.
- (A) 1-10% by weight of the cationic plasticizer
- (B) 0.1-2% by weight of an alkyl or alkenyl sulfate alkali, magnesium or ammonium salt.
Schließlich kann es in Textilweichmacher-Zusammensetzungen mit hohen Gehalten von mehr als 10 Gew.-% an kationischen Weichmacherverbindungen erforderlich sein, zur Verhinderung der Gelbildung strukturbrechende Elektrolyte, z.B. MgCl2 zuzusetzen. Durch kombinierte Anwendung dieser Elektrolyte und des verdickenden Zusatzes von Alkyl-, Alkenyl- oder Ethersulfat-Salzen wird eine besonders gute Stabilität auch höherkonzentrierter Textilweichmacher-Zusammensetzungen erreicht.Finally, in textile plasticizer compositions with high contents of more than 10% by weight of cationic plasticizer compounds it may be necessary to add structurally breaking electrolytes, for example MgCl 2 , to prevent gel formation. The combined use of these electrolytes and the thickening addition of alkyl, alkenyl or ether sulfate salts results in particularly good stability even of highly concentrated textile plasticizer compositions.
Zur Herstellung der erfindungsgemäßen Textilweichmacher-Zusammensetzung werden die Komponenten nacheinander in Wasser gelöst bzw. dispergiert. Bevorzugt erfolgt die Herstellung in der Weise, daß man aus den Komponenten (A), (B) und gegebenenfalls (C) eine homogene Schmelze (Prämix-Lösung) herstellt und diese in Wasser oder in der wässrigen Lösung der übrigen Komponenten dispergiert.To produce the textile plasticizer composition according to the invention, the components are dissolved or dispersed in water in succession. The preparation is preferably carried out by producing a homogeneous melt (premix solution) from components (A), (B) and optionally (C) and dispersing them in water or in the aqueous solution of the other components.
Die folgenden Beispiele sollen den Gegenstand der Erfindung erläutern ohne ihn hierauf zu beschränken.The following examples are intended to explain the subject matter of the invention without restricting it thereto.
Es wurden Textilweichmacher-Dispersionen der folgenden Zusammensetzungen hergestellt (Tabelle) und die Viskositäten mit Hilfe eines Brookfield-Rotationsviskosimeters bestimmt:
Als kationischer Weichmacher (A) wurde eine Verbindung der Formel
Als Talgfettalkohol-sulfat (B1) wurde das Handelsprodukt Sulfopon T55 (Henkel KGaA), eine ca. 50 %ige wässrige Paste eingesetzt. Als Kokos-Talg (1:1) Fettalkoholsulfat (B2) wurde das Handelsprodukt Sulfopon KT115 (Henkel KGaA), eine ca. 40 %ige wässrige Paste verwendet.The commercial product Sulfopon T55 (Henkel KGaA), an approx. 50% aqueous paste, was used as tallow fatty alcohol sulfate (B1). The commercial product Sulfopon KT115 (Henkel KGaA), an approx. 40% aqueous paste, was used as coconut tallow (1: 1) fatty alcohol sulfate (B2).
Die %-Angaben in der Tabelle beziehen sich auf Wirkstoffgehalte.The percentages in the table relate to active substance contents.
Proben aus Polyester-Testgewebe wurden je dreimal mit einem handelsüblichen Waschmittel (PERSIL supra, ohne besonderen soil-repellent-Zusatz) bei 40°C in einer Waschmaschine gewaschen. Die Hälfte der Proben wurde mit einem erfindungsgemäßen Wäscheweichspülmittel (gemäß Beispiel 2, Dosierung 100 ml im Nachspülgang der Waschmaschine) gespült.Samples of polyester test fabric were washed three times with a commercially available detergent (PERSIL supra, without special soil repellent additive) at 40 ° C in a washing machine. Half of the samples were rinsed with a fabric softener according to the invention (according to Example 2, dosage 100 ml in the rinse cycle of the washing machine).
Die andere Hälfte der Proben wurde mit dem Vergleichsprodukt (gemäß Beispiel 1) in gleicher Weise gespült. Dann wurden die Proben der erfindungsgemäß weichgespülten Testgewebe und der Vergleichs-Testgewebe mit folgenden Testanschmutzungen beaufschlagt.
Dann wurden alle Testgewebe 1 x wie vorher gewaschen und nur mit Wasser gespült.Then all test fabrics were washed once as before and rinsed only with water.
Der Grad der Fleckentfernung wurde visuell wie folgt benotet:
- 0 = völlige Fleckentfernung
- 1 = Spuren erkennbar
- 2 = geringe Fleckreste
- 3 = deutliche sichtbare Fleckreste
- 4 = starke Fleckreste
- 5 = Fleck voll erhalten.
- 0 = complete stain removal
- 1 = traces recognizable
- 2 = minor stain residues
- 3 = clearly visible stain residues
- 4 = strong stain residues
- 5 = stain fully preserved.
Die Noten für die Fleckentfernung wurden über die 11 Testanschmutzungen ermittelt (Durchschnittsnote).The marks for the stain removal were determined on the 11 test stains (average grade).
Es wurden folgende Durchschnittsnoten für die Fleckentfernung erhalten:
In einer weiteren Versuchsreihe wurde das Polyester-Testgewebe wie vorher gewaschen, gespült und angeschmutzt. Es wurde aber ein Waschmittel mit einem "soil-repellent-Wirkstoff (PERSIL supra mit 1 Gew.-% Repel-0-Tex(R)) eingesetzt. Der soil-repellent-Wirkstoff Repel-0-Tex(R) ist ein Polyester aus Dimethylterephthalat, Ethylenglycol und Polyethylenglycol, erhältlich von Fa. Rhone-Poulenc.In a further test series, the polyester test fabric was washed, rinsed and soiled as before. However, a detergent with a "soil repellent active ingredient (PERSIL supra with 1% by weight Repel-0-Tex (R) ) was used. The soil repellent active ingredient Repel-0-Tex (R) is a polyester from dimethyl terephthalate, ethylene glycol and polyethylene glycol, available from Rhone-Poulenc.
Auch bei dieser Versuchsreihe konnte eine zusätzliche schmutzabweisende Wirkung durch die erfindungsgemäße Textilweichmacher-Zusammensetzung festgestellt werden:
