Description

Gewaschene Textilien, besonders solche aus Naturfasern, weisen nach dem Trocknen eine unangenehme Verhärtung auf. Außerdem ist bei Kunstfasern die elektrostatische Aufladung während des Tragens eine unangenehme Eigenschaft.
Derartige negative Eigenschaften der Maschinenwäsche können durch eine Nachbehandlung des Waschgutes im letzten Spülgang mit sogenannten Wäschweichspülmitteln weitgehend beseitigt werden. Auch die Lebensdauer eines Wäschestücks wird nachweislich verlängert. Weiterhin wird durch den Einsatz von Wäscheweichspülmitteln die Restfeuchte nach dem Schleudern reduziert und dadurch die Trockenzeit verkürzt. An ein gutes Konzentrat von Wäscheweichspülmitteln werden folgende Anforderungen gestellt:
Gute Kaltwasserdispergierbarkeit, kein Nachdicken der Formulierung bei Lagern, keine Trennungserscheinung der Formulierung und keine Bildung von Bodensatz.Washed textiles, especially those made from natural fibers, show an unpleasant hardening after drying. In addition, the electrostatic charge is an unpleasant property when wearing synthetic fibers.
Such negative properties of machine wash can be largely eliminated by post-treatment of the laundry in the last rinse cycle with so-called fabric softeners. The lifespan of a piece of laundry is also demonstrably extended. The use of fabric softening agents also reduces the residual moisture after spinning and thus shortens the drying time. The following requirements are placed on a good concentrate of fabric softener:
Good cold water dispersibility, no thickening of the formulation in storage, no separation of the formulation and no formation of sediment.

DE-A-29 23 141 offenbart Wäscheweichspülmittel, enthaltend quaternäre Ammoniumverbindungen als kationische Weichmacher. Bei den dort beschriebenen Wäscheweichspülmitteln werden die vorstehend genannten Anforderungen dadurch erfüllt, daß man die als Wäscheweichspülmittel dienenden quaternären Ammoniumverbindungen mit einem Fettsäurealkylolamidoethoxylat kombiniert.DE-A-29 23 141 discloses fabric softening agents containing quaternary ammonium compounds as cationic softeners. In the fabric softening agents described there, the above-mentioned requirements are met by combining the quaternary ammonium compounds serving as fabric softening agents with a fatty acid alkylolamidoethoxylate.

DE-A-30 25 369 nennt Wäscheweichspülmittelkonzentrate, enthaltend quaternäre Ammoniumverbindungen als kationische Weichmacher. Die Herstellung der dort beschriebenen Wäscheweichspülmittelkonzentrate wird durch den Zusatz von Fettsäurealkylolamidoxalkylaten sowie nichtionischen Dispergatoren oder Emulgatoren auf der Basis von Oxalkylaten, die mit dazu beitragen, daß das Konzentrat in kaltem Wasser gut dispergierbar ist, erreicht.DE-A-30 25 369 mentions laundry softener concentrates containing quaternary ammonium compounds as cationic softeners. The fabric softener concentrates described there are produced by adding fatty acid alkylolamidoxalkylates and nonionic dispersants or emulsifiers based on oxalkylates, which help to ensure that the concentrate is readily dispersible in cold water.

DE-A-32 04 165 beschreibt konzentrierte Wäscheweichspülmittel auf Basis von für Wäscheweichspülmittel üblichen quaternären Ammoniumverbindungen. Die an ein Konzentrat von Wäscheweichspülmitteln gestellten Anforderungen werden dadurch erfüllt, daß man die quaternären Ammoniumverbindungen mit einer gewissen Menge eines Fettaminpolyglykolethers kombiniert.DE-A-32 04 165 describes concentrated fabric softening agents based on quaternary ammonium compounds customary for fabric softening agents. The requirements placed on a concentrate of fabric softening agents are met by combining the quaternary ammonium compounds with a certain amount of a fatty amine polyglycol ether.

Es wurde nun gefunden, daß durch Kombination von kationischen Weichmachern mit Estern von gesättigten und/oder ungesättigten C₁-C₂₁-Carbonsäuren mit zwei- bis vierwertigen Alkoholen hochkonzentrierte, dünnflüssige Wäscheweichspülmittel hergestellt werden können, die sämtliche an ein gutes Konzentrat gestellte Anforderungen erfüllen.It has now been found that by combining cationic plasticizers with esters of saturated and / or unsaturated C₁-C₂₁ carboxylic acids with di- to tetravalent alcohols, highly concentrated, low-viscosity fabric softeners can be produced which meet all the requirements placed on a good concentrate.

  • a) 5 - 40 Gew.-%, vorzugsweise 10 - 25 Gew.-%, eines kationischen Weichmachers,
  • b) 0,1 - 25 Gew.-%, vorzugsweise 0,5 - 15 Gew.-%, eines Esters einer C₁-C₂₂-Carbonsäure mit einem zwei-, drei- oder vierwertigen Alkohol mit 2 bis 10 Kohlenstoffatomen, sowie gegebenenfalls
  • c) 0 - 10 Gew.-%, vorzugsweise 0,5 - 5 Gew.-%, eines nichtionischen Dispergiermittels,
  • d) 0 - 20 Gew.-%, vorzugsweise 0,5 - 10 Gew.-%, eines Polyglykols,
  • e) Wasser und gegebenenfalls weitere übliche Hilfsstoffe entsprechend dem Ausgleich zu 100 Gew.-%.
The invention thus relates to fabric softener concentrates consisting of
  • a) 5-40% by weight, preferably 10-25% by weight, of a cationic plasticizer,
  • b) 0.1-25% by weight, preferably 0.5-15% by weight, of an ester of a C₁-C₂₂ carboxylic acid with a di-, tri- or tetravalent alcohol having 2 to 10 carbon atoms, and optionally
  • c) 0-10% by weight, preferably 0.5-5% by weight, of a nonionic dispersant,
  • d) 0-20% by weight, preferably 0.5-10% by weight, of a polyglycol,
  • e) water and, if appropriate, other customary auxiliaries in accordance with the balance at 100% by weight.

Die Menge dieser nichtionischen Dispergiermittel beträgt 0 bis 10 Gew.-%, vorzugsweise 0,5 bis 5 Gew.-%, bezogen auf das Gesamtgewicht des Konzentrates.A further constituent can be customary nonionic dispersants based on oxalkylates, which help to ensure that the fabric softener is readily dispersible in cold water. Suitable nonionic dispersants are reaction products of in each case about 2 to 12 moles of ethylene oxide with an alkylphenol, for example xylenol, but also with an alkylphenol with a long alkyl radical of 8 to 10 carbon atoms or with a fatty alcohol or fatty amine with 6 to 22 carbon atoms, preferably 8 to 18 carbon atoms. These include in particular Reaction products of about 5 to 8 moles of ethylene oxide with 1 mole of alkylphenol or 1 mole of fatty alcohol or fatty amine or a mixture of such fatty alcohols and / or fatty amines. The amount of these nonionic dispersants is 0 to 10% by weight, preferably 0.5 to 5% by weight, based on the total weight of the concentrate.

Die erfindungsgemäßen Wäscheweichspülmittelkonzentrate enthalten gegebenfalls 0 bis 20, vorzugsweise 0,5 bis 10 Gew.-% eines Polyglykols, bevorzugt werden Polyethylenglykole mit einem Mw von 400 bis 1000 (Gewichtsmittel) und/oder Polypropylenglykols sowie die C₁-C₄-Alkylether dieser Verbindungen. Diese Verbindungen zeigen eine lösungsvermittelnde Wirkung und sind daher insbesondere als Zusatzstoff zur Herstellung von transparenten Wäscheweichspülmittelkonzentraten geeignet.The fabric softener concentrates according to the invention optionally contain 0 to 20, preferably 0.5 to 10 wt .-% of a polyglycol, preferably polyethylene glycols with an M w of 400 to 1000 (weight average) and / or polypropylene glycol and the C₁-C₄ alkyl ethers of these compounds. These compounds have a solubilizing effect and are therefore particularly suitable as an additive for the production of transparent fabric softener concentrates.

Darüber hinaus können die erfindungsgemäßen konzentrierten Wäscheweichspülmittel noch weitere übliche Substanzen und Hilfsmittel enthalten, die entweder schon im Konzentrat zugemischt oder dem gebrauchsfertigen, verdünnten Wäscheweichspülmittel gesondert zugesetzt werden. Hierbei handelt es sich um kationische oder nichtionische oberflächenaktive Substanzen, Elektrolyte, Absäuerungsmittel, organische Komplexbildner, optische Aufhellungsmittel, Lösungsvermittler sowie Farb- und Duftstoffe. Sie dienen zur zusätzlichen Beeinflussung des Warengriffs oder sonstigen Eigenschaften der zu behandelnden Textilien oder zur Viskositätseinstellung, zur pH-Wert-Regulierung oder zu Erhöhung der Kältestabilität.In addition, the concentrated fabric softener according to the invention can also contain other customary substances and auxiliaries which are either already mixed in the concentrate or added separately to the ready-to-use, diluted fabric softener. These are cationic or non-ionic surface-active substances, electrolytes, acidifying agents, organic complexing agents, optical brighteners, solubilizers and colorants and fragrances. They serve to additionally influence the handle of the goods or other properties of the textiles to be treated or to adjust the viscosity, to regulate the pH value or to increase the stability at low temperatures.

Die erfindungsgemäßen Wäscheweichspülmittelkonzentrate haben einen Feststoffgehalt von mindestens 25 Gew.-%, vorzugsweise 25 bis 75 Gew.-%, besonders bevorzugt 25 bis 60 Gew.-%.The laundry fabric softener concentrates according to the invention have a solids content of at least 25% by weight, preferably 25 to 75% by weight, particularly preferably 25 to 60% by weight.

Die erfindungsgemäßen Wäscheweichspülmittelkonzentrate verleihen beliebigen Textilmaterialien, besonders solchen aus natürlicher oder regenerierter Cellulose, Wolle, Celluloseregenerat, Cellulosetriacetat, Polyamid, Polyacrylnitril, Polyester oder Polypropylen einen angenehmen und weichen Griff. Besonders vorteilhaft ist der Einsatz als Wäschenachbehandlungsmittel für Frottee und Leibwäsche.The laundry softener concentrates according to the invention impart any textile materials, especially those made from natural or regenerated cellulose, Wool, regenerated cellulose, cellulose triacetate, polyamide, polyacrylonitrile, polyester or polypropylene have a pleasant and soft feel. The use as a laundry treatment agent for terry cloth and underwear is particularly advantageous.

Die Herstellung dieser Konzentrate erfolgt durch einfaches Vermischen oder Dispergieren der Einzelkomponenten a) bis d) und gegebenenfalls e) in Wasser. Die Konzentrate enthalten entweder jeweils eine Verbindung der Komponenten a) bis e) oder sie enthalten ein Gemisch aus zwei oder mehr Verbindungen der Komponenten a) bis e) innerhalb der angegebenen Grenzen. Liegt ein Gemisch aus zwei oder mehr Verbindungen der Komponenten a, b, c, d oder e vor, so ist deren Mischungsverhältnis untereinander völlig unkritisch und kann jeden beliebigen Wert annehmen. Die Mengen der einzelnen Komponenten a) bis d) werden innerhalb der angegebenen Grenzen so gewählt, daß das fertige Konzentrat, einschließlich eventuell zusätzlicher Mengen an Wasser und Hilfsstoffe, 100 Gew.- % ergibt. Die Einsatzmenge der erfindungsgemäßen Wäscheweich-spülmittelkonzentrate beträgt etwa 10 - 20 g pro 4 kg Wäsche. Die Anwendung dieser Konzentrate erfolgt wie üblich, indem man sie im Anschluß an die Textilwäsche in das letzte Spülwasser gibt. Die vorstehend beschriebenen Wäscheweichspülmittelkonzentrate weisen gute weichmachende Eigenschaften auf. Sie zeichnen sich durch eine gute Parfümverträglichkeit und Stabilität aus. Die Kaltwasserdispergierbarkeit ist hervorragend. Eine Gelbildung wurde nicht beobachtet. Die Formulierungen zeigen auch in hoher konzentrierter Form eine niedrige Viskosität. Ein Nachdicken oder Gelieren nach längerer Lagerzeit (30 Tage) tritt nicht auf. Weiterer Gegenstand der Erfindung ist somit die Verwendung der erfindungsgemäßen Wäscheweichspülmittelkonzentrate zur Herstellung von Emulsionen.These concentrates are prepared by simply mixing or dispersing the individual components a) to d) and, if appropriate, e) in water. The concentrates either contain one compound of components a) to e) or they contain a mixture of two or more compounds of components a) to e) within the specified limits. If there is a mixture of two or more compounds of components a, b, c, d or e, their mixing ratio with one another is completely uncritical and can take on any value. The amounts of the individual components a) to d) are chosen within the limits specified so that the finished concentrate, including any additional amounts of water and auxiliaries, gives 100% by weight. The amount of the fabric softener / detergent concentrate according to the invention is about 10-20 g per 4 kg of laundry. These concentrates are used as usual by adding them to the final rinse water after washing the fabrics. The fabric softener concentrates described above have good softening properties. They are characterized by good perfume compatibility and stability. The cold water dispersibility is excellent. No gel formation was observed. The formulations also show a low viscosity in a highly concentrated form. Thickening or gelling after a long storage period (30 days) does not occur. Another object of the invention is thus the use of the fabric softener concentrates according to the invention for the production of emulsions.
