The foaming behaviour of liquid detergents containing non-ionic and ionic tensides can be regulated by a combination of foam-regulating soaps and silicons, the soap content being preferably higher than the silicon content.

Description

Waschmittel, die zum Waschen in automatischen Waschmaschinen verwendet werden, müssen im Schaumverhalten so eingestellt werden, daß es während des Waschprozesses nicht zum Überschäumen der Maschine kommt und der Schaum beim Spülen auch wieder ausreichend gut aus den Textilien ausgespült wird. Sowohl bei pulverförmigen als auch flüssigen Waschmitteln läßt sich das Schaumverhalten mit Hilfe von Seifen auf das gewünschte Niveau einstellen. Bei flüssigen Waschmitteln hat dies allerdings den Nachteil, daß mit zunehmendem Seifenanteil auch die Viskosität weit über das gewünschte Maß hinaus ansteigt. Um die Viskosität dann wieder auf den gewünschten Wert zu reduzieren, ist es in der Regel notwendig, Lösungsmittel, wie z. B. Ethanol oder Propylenglykol oder hydrotrope Substanzen, einzusetzen, was für den Fall eines Zusatzes brennbarer Lösungsmittel mit dem Nachteil einer Flammpunkterniedrigung verbunden ist.Detergents that are used for washing in automatic washing machines must be set in the foam behavior so that there is no foaming of the machine during the washing process and the foam is also rinsed out of the textiles sufficiently well when rinsing. With both powdered and liquid detergents, the foam behavior can be adjusted to the desired level with the help of soaps. In the case of liquid detergents, however, this has the disadvantage that, with an increasing proportion of soap, the viscosity also increases far beyond the desired level. In order to then reduce the viscosity back to the desired value, it is usually necessary to use solvents such as. As ethanol or propylene glycol or hydrotropic substances to use, which is associated with the disadvantage of a lowering of the flash point in the case of the addition of flammable solvents.

Eine andere Möglichkeit der Schaumdämpfung besteht in der Verwendung von Silikon- oder Paraffinentschäumern. Mit diesen Entschäumertypen läßt sich zwar der Schaum während des Waschprozesses auf ein nahezu beliebiges Niveau einstellen, aber der Schaum läßt sich schlecht ausspülen.Another way of dampening the foam is to use silicone or paraffin defoamers. With these types of defoamers, the foam can be adjusted to almost any level during the washing process, but the foam is difficult to rinse out.

Aus EP-A-0 081 908 ist ein flüssiges Waschmittel bekannt, das zur Schaumregulierung Seife in Kombination mit Silikonentschäumern enthält. Ein Hinweis darauf, wie die Viskosität dieser Waschmittel reguliert werden kann, ist dieser Literaturstelle nicht zu entnehmen.From EP-A-0 081 908 a liquid detergent is known which contains soap in combination with silicone defoamers for foam regulation. There is no indication of how the viscosity of these detergents can be regulated in this reference.

Es wurde nun überraschenderweise gefunden, daß ein flüssiges Waschmittel, enthaltend anionische und nichtionische Tenside sowie Schaumregulatoren und gegebenenfalls sonstige übliche Waschmittelbestandteile, und das dadurch gekennzeichnet ist, daß es ein Kondensationsprodukt aus einem natürlichen Fett und einem Hydroxyalkylpolyamin in Mengen von 0,2 bis 10 Gew.-% und als Schaumregulator eine Kombination aus Seife und Silikonen enthält, die gewünschten Schaumeigenschaften hat. Erfindungsgemäß zusammengesetzte Waschmittel weisen nicht nur die erforderliche mäßige Schaumentwicklung bei der Maschinenwäsche und die kräftige Schaumentwicklung bei der Handwäsche auf, sondern der gebildete Schaum läßt sich sowohl bei der Maschinenwäsche als auch bei der Handwäsche in den sich anschließenden Spülvorgängen mit Wasser leicht herausspülen. Die zu einer eventuell erforderlichen Viskositätskorrektur erforderlichen Lösungsmittelmengen sind viel geringer als ohne den erfindungsgemäßen Einsatz des Kondensationsproduktes und der Schaumregulatoren; in vielen Fällen werden überhaupt keine Lösungsmittel benötigt. Die Kombination von Seife und Silikonen als Schaumregulator für die Flüssigwaschmittel der vorliegenden Patentanmeldung gestattet es, das gewünschte Schaumverhalten mit sehr viel weniger Seife einzustellen als normalerweise bei den Waschmitteln des Standes der Technik für die Schaumregulierung erforderlich ist. Das gewünschte Schaumverhalten wird vorzugsweise durch ein Gewichtsverhältnis von Seife zu Silikon im Bereich von 100 : 1 bis 2 : 1, insbesondere im Bereich von 20 : 1 bis 5 : 1 erreicht. Die zur Schaumregulierung verwendete Seifen sind vorzugsweise Kalium-, Monoethanolamin- oder Triethanolaminsalze, und insbesondere Natriumsalze von Fettsäuren mit 10 bis 20 Kohlenstoffatomen. Die Fettsäuren können synthetischen oder natürlichen Ursprungs sein und sowohl gesättigt als auch ungesättigt sein. Eine besonders gut geeignete Seife ist beispielsweise das Natriumsalz eines Fettsäuregemisches mit 12 bis 18 Kohlenstoffatomen.It has now surprisingly been found that a liquid detergent containing anionic and nonionic surfactants and foam regulators and, if appropriate, other customary detergent constituents, and which is characterized in that it is a condensation product of a natural fat and a hydroxyalkyl polyamine in amounts of 0.2 to 10 Wt .-% and contains a combination of soap and silicone as foam regulator, which has the desired foam properties. Detergents composed according to the invention not only have the required moderate foaming during machine washing and the strong foaming during hand washing, but the foam formed can be easily rinsed out with water both during machine washing and hand washing in the subsequent rinsing processes. The amounts of solvent required for any viscosity correction that may be required are much smaller than without the use of the condensation product and the foam regulators according to the invention; in many cases, no solvents are required at all. The combination of soap and silicone as a foam regulator for the liquid detergents of the present patent application allows the desired foaming behavior to be set with much less soap than is normally required for the foam regulators in the prior art. The desired foaming behavior is preferably achieved by a weight ratio of soap to silicone in the range from 100: 1 to 2: 1, in particular in the range from 20: 1 to 5: 1. The soaps used for foam regulation are preferably potassium, monoethanolamine or triethanolamine salts, and in particular sodium salts of fatty acids with 10 to 20 carbon atoms. The fatty acids can be synthetic or natural in origin and can be both saturated and unsaturated. A particularly suitable soap is, for example, the sodium salt of a fatty acid mixture with 12 to 18 carbon atoms.

Die zur Schaumregulierung verwendeten Silikone sind vorzugsweise emulgierte Organopolysiloxane, die insbesondere im Gemisch mit 1 bis 10 Gewichtsprozent, bezogen auf das Silikon, einer feinteiligen, vorzugsweise silanierten Kieselsäure sowie einem Emulgiermittel vorliegen, womit eine homogene Verteilung des Organopolysiloxans in Wasser beziehungsweise im wasserhaltigen Gemisch der übrigen Waschmittelbestandteile bewirkt wird. Brauchbar sind insbesondere Dimethylpolysiloxane, die im Gemisch mit silanierter Kieselsäure und nichtionogenen Emulgatoren vorliegen. Geeignete Emulgatoren sind zum Beispiel Polyglykolether, die durch längerkettige Alkohole, Alkylphenole, Fettsäuren und Fettsäureamide substituiert sind. Auch höhermolekulare unsubstituierte Polyglykolether sowie Blockpolymere aus Polyethylenglykol und Polypropylenglykol und Gemische der vorgenannten Emulgatoren sind geeignet. Im allgemeinen sind die Gemische aus Dimethylpolysiloxan, Kieselsäure und Emulgator als bereits fertig konfektionierte Produkte im Handel.The silicones used for foam regulation are preferably emulsified organopolysiloxanes, which are present in particular in a mixture with 1 to 10 percent by weight, based on the silicone, of a finely divided, preferably silanized silicic acid and an emulsifier, so that the organopolysiloxane is homogeneously distributed in water or in the water-containing mixture of the rest Detergent ingredients is effected. Dimethylpolysiloxanes which are present in a mixture with silanized silica and nonionic emulsifiers are particularly useful. Suitable emulsifiers are, for example, polyglycol ethers which are substituted by longer-chain alcohols, alkylphenols, fatty acids and fatty acid amides. High molecular weight unsubstituted polyglycol ethers as well as block polymers from polyethylene glycol and polypropylene glycol and mixtures of the aforementioned emulsifiers are suitable. In general, the mixtures of dimethylpolysiloxane, silica and emulsifier are commercially available as ready-made products.

Die als Schaumregulator verwendete Kombination aus Seife und Silikon liegt in dem Waschmittel vorzugsweise in einer Konzentration von 0,5 bis 10 Gewichtsprozent, insbesondere von 1 bis 5 Gewichtsprozent vor, wobei der Anteil der Seife im Waschmittel etwa 0,5 bis 5 und insbesondere 1 bis 2 Gewichtsprozent des Waschmittels ausmacht.The combination of soap and silicone used as a foam regulator is preferably present in the detergent in a concentration of 0.5 to 10 percent by weight, in particular 1 to 5 percent by weight, the proportion of soap in the detergent being approximately 0.5 to 5 and in particular 1 to Makes up 2 percent by weight of the detergent.

Das erfindungsgemäße Waschmittel enthält als Textilweichmacher zusätzlich ein Kondensationsprodukt aus einem natürlichen Fett und einem Hydroxyalkylpolyamin, wie es aus der Deutschen Patentanmeldung DE-A-19 22 046 bekannt ist. Besonders gute weichmachende Eigenschaften hat dabei ein Kondensationsprodukt, das sich von hydriertem Rindertalg ableitet und mit Hydroxyethylethylendiamin im Molverhältnis 1 : 1 kondensiert wurde. Das erfindungsgemäße flüssige Waschmittel enthält ein derartiges Kondensationsprodukt in Konzentrationen von 0,2 bis 10 Gewichtsprozent.The laundry detergent according to the invention additionally contains a condensation product of a natural fat and a hydroxyalkyl polyamine as textile softener, as is known from German patent application DE-A-19 22 046. A condensation product which is derived from hydrogenated beef tallow and which has been condensed with hydroxyethylethylenediamine in a molar ratio of 1: 1 has particularly good softening properties. The liquid detergent according to the invention contains such a condensation product in concentrations of 0.2 to 10 percent by weight.

Einen Einfluß auf die Eigenschaften des erfindungsgemäßen Waschmittels hat auch das Verhältnis von anionischem Tensid zu nichtionischem Tensid, das bei bevorzugten erfindunsgemäßen Waschmitteln im Gewichtverhältnis von 5 : 1 bis 1 : 5, insbesondere 4 : 1 bis 2 : 1 vorliegt. Besonders gute Eigenschaften weist ein Waschmittel auf, das als anionisches Tensid ein Gemisch aus Alkylbenzolsulfonat-Natrium und Alkylethersulfat-Natrium oder Alkylsulfat-Natrium insbesondere im Gewichtsverhältnis von 8 : 1 bis 4 : 1 enthält. Ein besonders gut geeignetes Alkylethersulfat leitet sich von einem C₁₂ - C₁₄-Fettalkohol, an den 2 oder 3 Mol Ethylenoxid angelagert sind, ab. Das Alkylbenzolsulfonat-Natrium oder das Alkylethersulfat-Natrium können ganz oder teilweise durch Alkylsulfat-Natrium ersetzt sein. Das erfindungsgemäße Waschmittel enthält als nichtionische Tenside Anlagerungsprodukte von Ethylenoxid und/oder Propylenoxid an Fettalkohole oder Oxoalkohole. Ein erfindungsgemäßes Waschmittel mit wertvollen Eigenschaften enthält beispielweise als nichtionisches Tensid einen C₁₃ - C₁₅-Oxoalkohol, an den 7 Mol Ethylenoxid angelagert wurden.The ratio of anionic surfactant to nonionic surfactant, which is present in preferred detergents according to the invention in a weight ratio of 5: 1 to 1: 5, in particular 4: 1 to 2: 1, also has an influence on the properties of the detergent according to the invention. A detergent which contains, as an anionic surfactant, a mixture of alkylbenzenesulfonate sodium and alkyl ether sulfate sodium or alkyl sulfate sodium, in particular in a weight ratio of 8: 1 to 4: 1, has particularly good properties. A particularly suitable alkyl ether sulfate is derived from a C₁₂ - C₁₄ fatty alcohol to which 2 or 3 moles of ethylene oxide are attached. The alkyl benzene sulfonate sodium or the alkyl ether sulfate sodium can be replaced in whole or in part by alkyl sulfate sodium. The detergent according to the invention contains addition products of ethylene oxide and / or propylene oxide with fatty alcohols as nonionic surfactants or oxo alcohols. A detergent according to the invention with valuable properties contains, for example, as a nonionic surfactant a C₁₃ - C₁₅ oxo alcohol, to which 7 moles of ethylene oxide have been added.

Als Lösungsmittel kommen vor allem Alkanole oder Alkandiole mit 2 oder 3 Kohlenstoffatomen, insbesondere Ethanol, Isopropylalkohol und Propandiole oder Glycerin infrage. Außerdem können hydrotrope Substanzen, insbesondere Toluolsulfonat, Cumolsulfonat oder Harnstoff eingesetzt werden. Die Menge an Lösungsmittel und hydrotropen Substanzen in bevorzugten erfindungsgemäßen Waschmitteln liegt im Bereich von 0,5 bis 15 Gew.-%. Falls Ethanol und Propandiole gemeinsam verwendet werden, liegt das Mengenverhältnis von Ethanol zu Propandiol im Bereich von 2 : 1 bis 1 : 6.Alkanols or alkanediols having 2 or 3 carbon atoms, in particular ethanol, isopropyl alcohol and propanediols or glycerol, are particularly suitable as solvents. Hydrotropic substances, in particular toluenesulfonate, cumene sulfonate or urea, can also be used. The amount of solvent and hydrotropic substances in preferred detergents according to the invention is in the range from 0.5 to 15% by weight. If ethanol and propanediols are used together, the quantitative ratio of ethanol to propanediol is in the range from 2: 1 to 1: 6.

Zusätzlich können die erfindungsgemäßen Waschmittel noch übliche Bestandteile von Flüssigwaschmitteln enthalten, beispielweise Enzyme, Konservierungsstoffe, Duftstoffe, Farbstoffe sowie Wasser enthalten. Auch organische oder anorganische Buildersubstanzen und Farbinhibitoren können in den erfindungsgemäßen Waschmitteln enthalten sein.In addition, the detergents according to the invention can also contain conventional constituents of liquid detergents, for example enzymes, preservatives, fragrances, dyes and water. Organic or inorganic builder substances and color inhibitors can also be present in the detergents according to the invention.

Die erfindungsgemäßen Waschmittel weisen beispielsweise eine Viskosität im Bereich von 400 bis 1 500 mPas bei 20 °C auf und haben ausgezeichnete Waschkraft. Durch Variation der Schaumregulator-Kombination läßt sich das Schaumverhalten in weiten Grenzen nahezu beliebig einstellen. Die Waschmittelbestandteile sind zudem preiswert und in großer Menge verfügbar. Gewünschtenfalls ist auch der Zusatz von Trübungsmitteln ohne Beeinträchtigung der Waschmitteleigenschaften möglich. Gewünschtenfalls können auch erfindungsgemäße Produkte mit niedrigerer Viskosität, beispielsweise 200 mPas, oder mit höherer Viskosität, beispielsweise 3000 mPas durch Zusatz unterschiedlicher Mengen Kondensationsprodukt, erforderlichenfalls unter Mitverwendung nur geringer Lösungsmittelmengen, hergestellt werden, die den Vorteil eines geringen Lösungsmittelanteils haben.The detergents according to the invention have, for example, a viscosity in the range from 400 to 1,500 mPas at 20 ° C. and have excellent detergency. By varying the foam regulator combination, the foam behavior can be set almost anywhere within wide limits. The detergent ingredients are also inexpensive and available in large quantities. If desired, addition of opacifiers is also possible without impairing the detergent properties. If desired, products according to the invention with a lower viscosity, for example 200 mPas, or with a higher viscosity, for example 3000 mPas, can also be produced by adding different amounts of condensation product, if necessary using only small amounts of solvent, which have the advantage of a low solvent content.

Durch die erfindungsgemäße Kombination an Schaumregulator aus Seife und Silikonen einerseits und dem als Textilweichmacher bekannten Kondensationsprodukt andererseits lassen sich flüssige Waschmittel herstellen, deren Viskosität innerhalb eines großen Bereiches ohne Zusatz von viskositätsbeeinflussenden Lösungsmitteln herstellen. Die erfindungsgemäßen Waschmittel haben nicht nur eine geringe Schaumbildung beim Waschen und Spülen in der Waschmaschine und eine kräftige Schaumentwicklung bei der Handwäsche, sondern sie haben, je nach Bedarf, auch eine dünnflüssige oder dickflüssige Konsistenz, wie sie je nach Anwendung vom Verbraucher gewünscht wird.The inventive combination of foam regulator made of soap and silicone on the one hand and the condensation product known as textile softener on the other hand enables liquid detergents to be produced whose viscosity can be produced within a wide range without the addition of solvents which influence viscosity. The detergents according to the invention not only have low foaming when washing and rinsing in the washing machine and strong foaming during hand washing, but they also have, depending on the need, a thin or viscous consistency as desired by the consumer depending on the application.
