Description

Gegenstand der vorliegenden Erfindung ist ein flüssiges Wasch- und Reinigungsmittel auf Basis von nichtionischen Tensiden und wäscheweichmachenden quartären Ammoniumverbindungen, das zusätzlich kationische Stärkeether enthält, wodurch der Farbstoffübertragung von farbigen Textilien auf weiße oder hellfarbige Textilien während eines gemeinsamen Waschens entgegengewirkt wird.The present invention relates to a liquid washing and cleaning agent based on nonionic surfactants and laundry-softening quaternary ammonium compounds, which additionally contains cationic starch ethers, which counteracts the dye transfer from colored textiles to white or light-colored textiles during a joint washing.

Die Farbstoffübertragung bei der gemeinsamen Wäsche von farbigen mit weißen bzw. hellfarbigen Textilien ist ein seit langem bekanntes Problem, für das es bereits einige Lösungsvorschläge gibt, die aber alle nicht voll befriedigen können, weil sie gegenüber einer Reihe von Ausfärbungen bzw. Textilien nur eine geringe Wirkung aufweisen. So ist z.B. aus der DE-AS 22 32 353 ein Mittel bekannt, dessen verfärbungsinhibierender Zusatz Polyvinylpyrrolidon ist. Die DE-OS 24 20 561 beschreibt ein Waschmittel mit einer Kombination an Alkalimetall-Percarbonat und Polyethylenglykol eines bestimmten Molekulargewichts oder Polyvinylpyrrolidon. Die DE-OS 23 09 099 betrifft ein Mittel mit Anteilen an zwei verschiedenen organischen Verbindungen, die basische Stickstoffatome im Molekül enthalten. In der DE-OS 28 28 619 ist ein Waschmittel aus nichtionischen Tensiden, zwitterionischen oder semipolaren Tensiden und kationischen Tensiden in bestimmten Mengenverhältnissen beschrieben. In den US-PS 4 005 029 und 4 006 092 sind Mittel beschrieben, die Perverbindungen enthalten.The transfer of dyes when washing colored with white or light-colored textiles together has been a problem for a long time, for which there have already been some proposed solutions, but not all of them can be completely satisfactory because they are only marginal compared to a number of colors or textiles Have effect. For example, from DE-AS 22 32 353 an agent is known whose discoloration-inhibiting additive is polyvinylpyrrolidone. DE-OS 24 20 561 describes a detergent with a combination of alkali metal percarbonate and polyethylene glycol of a certain molecular weight or polyvinyl pyrrolidone. DE-OS 23 09 099 relates to an agent with proportions of two different organic compounds that contain basic nitrogen atoms in the molecule. DE-OS 28 28 619 describes a detergent composed of nonionic surfactants, zwitterionic or semipolar surfactants and cationic surfactants in certain proportions. U.S. Patents 4,005,029 and 4,006,092 describe compositions containing per compounds.

Es wurde nun gefunden, daß ein flüssiges Waschmittel auf Basis von nichtionischen Tensiden, das als wäscheweichmachenden Bestandteil übliche quartäre Ammoniumverbindungen enthält, durch den Zusatz von kationischen Stärkeethern sehr gute verfärbungsinhibierende Eigen- .schaften aufweist. Kationische Stärkeether sind bekannte handelsübliche Stoffe, die-als Zusätze zur Qualitätsverbesserung bei der Papier- und Karton-Herstellung verwendet werden. Die Herstellung der Stärkeether kann in an sich bekannter Weise, z.B. durch Umsetzung der Stärke, beispielsweise Kartoffelstärke, mit Ethylenimin (vgl. US-PS 3 303 184) und anschließende teilweise oder vollständige Quaternierung der Aminogruppe erfolgen: Vorzugsweise werden aber solche Ether als verfärbungsinhibierender Zusatz in Kombination mit textilweichmachenden quartären Ammoniumverbindungen verwendet, die beispielsweise durch Umsetzung von Stärke mit 2,3-Epoxypropyltrialkylammoniumsalzen oder 3-Chlor-2-hydroxypropyltrimethyl- ammoniumsalzen, insbesondere mit 2,3-Epoxypropyltrimethylammoniumchlorid erhalten werden. Derartige Umsetzungsprodukte sind beispielsweise in der GB-PS 1 136 842. beschrieben. Die Quartärsalze können als Halogenide, insbesondere Chloride, Sulfate, Alkylsulfate, Nitrate, Phosphate und als Salze organischer Säuren, z.B. als Acetate, Citrate oder Lactate vorliegen. Ein typisches Produkt ist Empresol N der Firma Emsland-Stärke GmbH, Emlichheim, Bundesrepublik Deutschland. Dies ist ein kationisches Kartoffelstärke-Derivat mit tertiären und quartären Stickstoffatomen, dessen kationische Ladung über die ganze Stärkekette gleichmäßig verteilt ist.It has now been found that a liquid detergent based on nonionic surfactants, which contains conventional quaternary ammonium compounds as a softening constituent, has very good discoloration-inhibiting properties due to the addition of cationic starch ethers. Cationic starch ethers are known commercially available substances which are used as additives for improving the quality of paper and cardboard manufacture. The starch ethers can be prepared in a manner known per se, e.g. by reacting the starch, for example potato starch, with ethyleneimine (cf. of starch with 2,3-epoxypropyltrialkylammonium salts or 3-chloro-2-hydroxypropyltrimethylammonium salts, in particular with 2,3-epoxypropyltrimethylammonium chloride. Such reaction products are described for example in GB-PS 1 136 842. The quaternary salts can be used as halides, especially chlorides, sulfates, alkyl sulfates, nitrates, phosphates and as salts of organic acids, e.g. are present as acetates, citrates or lactates. A typical product is Empresol N from Emsland -force GmbH, Emlichheim, Federal Republic of Germany. This is a cationic potato starch derivative with tertiary and quaternary nitrogen atoms, the cationic charge of which is evenly distributed over the entire starch chain.

Die Konzentration des Stärkeether-Zusatzes im Waschmittel liegt zwischen 5 und 50 Gew.-%, bezogen auf die eingesetzte Menge an nichtionischen Tensiden, und das Verhältnis des Stärkeethers zur weichmachenden quartären Ammoniumverbindung liegt zwischen 3 : 1 und 1 : 3.The concentration of the starch ether additive in the detergent is between 5 and 50% by weight, based on the amount of nonionic surfactants used, and the ratio of the starch ether to the plasticizing quaternary ammonium compound is between 3: 1 and 1: 3.

Bei den quartären Ammoniumverbindungen handelt es sich insbesondere um Derivate des Ammoniaks, d.h. um die durch Alkylierung von langkettigen sekundären Aminen erhältlichen quartären Salze, wie z.B. die Verbindungen Distearyldimethylammoniumchlorid bzw. Ditalgalkyldimethylammoniumchlorid. Als Anion kommen außer dem Chlorid noch Bromid, Methylsulfat, Ethylsulfat, Methan-, Ethan- oder Toluolsulfonat in Betracht. Andere mögliche quartäre Ammoniumverbindungen sind die durch Umsetzung von 1 Mol eines Aminoalkylethylendiamins oder Hydroxyalkylethylendiamins mit 2 Mol einer langkettigen, C14-C26-Fettsäure oder deren Ester erhältlichen Imidazolinverbindungen, die anschließend durch Alkylierung in die quartären Imidazolinium- verbindungen übergeführt werden.The quaternary ammonium compounds are, in particular, derivatives of ammonia, ie the quaternary salts obtainable by alkylation of long-chain secondary amines, such as, for example, the compounds distearyldimethylammonium chloride or ditalgalkyldimethylammonium chloride. In addition to the chloride, there is another anion Bromide, methyl sulfate, ethyl sulfate, methane, ethane or toluenesulfonate into consideration. Another possible quaternary ammonium compounds are the imidazoline compounds obtainable by reacting 1 mol of a Aminoalkylethylendiamins Hydroxyalkylethylendiamins or with 2 moles of a long chain, C14 -C26 fatty acid or its ester, which is then by alkylation in the quaternary imidazolinium - be converted compounds.

Typische bevorzugte Textilweichmacher sind beispielsweise die Handelsprodukte "Präpagen WK" und "Präpagen WKT" (Hoechst), "Adogen 442" (Ashland), bei denen es sich um Ditalgalkyldimethylammoniumsalze handelt. Diese Verbindungen sind zu 1 bis 10, vorzugsweise 2 bis 6 Gew.-% in dem erfindungsgemäßen Waschmittel enthalten.Typical preferred textile plasticizers are, for example, the commercial products "Präpagen WK" and "Präpagen WKT" (Hoechst), "Adogen 442" (Ashland), which are ditallow alkyldimethylammonium salts. 1 to 10, preferably 2 to 6% by weight of these compounds are present in the detergent according to the invention.

Typische bevorzugte Produkte sind beispielsweise "Dobanol 45-7", das zu mindestens 95 % aus C14/C15-Oxo Oxo-Alkohol mit durchschnittlich 7 Mol Ethylenoxid besteht, und "Lutensol AO-8", das ein C13/C15-Oxo-Alkohol-Ethoxylat mit durchschnittlich 8 Mol Ethylenoxid darstellt.Particularly preferred as component a) are alkyl polyglycol ethers which represent ethylene oxide condensates of the aforementioned oxo alcohols with 13 to 15 carbon atoms with an average ethylene oxide content of approximately 55 to 65% by weight. Typical preferred products are, for example, "Dobanol 45-7", which consists of at least 95% C 14 / C 15 oxo oxo alcohol with an average of 7 moles of ethylene oxide, and "Lutensol AO-8", which is a C 13 / C 15 Represents oxo alcohol ethoxylate with an average of 8 moles of ethylene oxide.

Als Bestandteil b) werden Alkylpolyglykolether bevorzugt, deren Alkoholbasis natürliche oder synthetische primäre Fettalkohole oder Oxo-Alkohole darstellen, die 9 bis 12 Kohlenstoffatome enthalten und einen Ethylenoxidgehalt von ca. 60 bis 70 Gew.-% aufweisen. Typische bevorzugte Produkte sind z.B. das Handelsprodukt "Marlipal KF" (Chemische Werke Hüls), das ein C10/C12-Fettalkohol-Ethoxylat mit durchschnittlich 6 Mol Ethylenoxid darstellt, sowie das "Lutensol ON-70", das ein C9/C11-Oxo-Alkohol-Ethoxylat mit durchschnittlich 7 Mol Ethylenoxid darstellt. Geeignete Fettalkohole als Basis für bevorzugte Alkylpolyglykolether sind auch die Handelsprodukte "Lorol C - 8 bis 12" (Henkel).As component b), preference is given to alkyl polyglycol ethers whose alcohol base is natural or synthetic primary fatty alcohols or oxo alcohols which contain 9 to 12 carbon atoms and have an ethylene oxide content of approximately 60 to 70% by weight. Typical preferred products are, for example, the commercial product "Marlipal KF" (Chemische Werke Huls), which is a C 10 / C 12 fatty alcohol ethoxylate with an average of 6 moles of ethylene oxide, and the " Lutensol ON-70 ", which is a C 9 / C 11 -Oxo alcohol ethoxylate with an average of 7 moles of ethylene oxide. Suitable fatty alcohols as the basis for preferred alkyl polyglycol ethers are also the commercial products "Lorol C-8 to 12" (Henkel).

Das Verhältnis der eingesetzten Menge des Bestandteils a) zur eingesetzten Menge des Bestandteils b) bestimmt wesentlich die Parameter Waschkraft, Schäumverhalten und weichmachende Wirkung. Optimale Ergebnisse werden erhalten, wenn das Verhältnis von a) : b) zwischen etwa 2 : 1 und 1 : 2 liegt.The ratio of the amount of component a) used to the amount of component b) essentially determines the parameters of washing power, foaming behavior and softening effect. Optimal results are obtained when the ratio of a): b) is between about 2: 1 and 1: 2.

Im allgemeinen werden von Bestandteil a) und Bestandteil b) Mengen von zusammen 10 bis 30 Gew.-%, bezogen auf das Gesamtgewicht des Waschmittels, eingesetzt, wobei eine Menge von 15 bis 30 Gew.-% bevorzugt wird.In general, amounts of component a) and component b) of 10 to 30% by weight, based on the total weight of the detergent, are used, an amount of 15 to 30% by weight being preferred.

Als Lösungsmittel für die erfindungsgemäßen Waschmittel wird vorzugsweise Wasser verwendet. Es können aber auch organische Lösungsmittel in Mengen bis zu 20, vorzugsweise bis zu 16 Gew.-% des gesamten flüssigwaschmittels mit verwendet werden. Derartige zusätzliche Lösungsmittel sind entweder niedere Alkanole oder niedere Diole oder Polyole wie beispielsweise Ethanol, Isopropylalkohol, Ethylenglykol, Propylenglykol oder Glycerin. Gegebenenfalls können auch Polyole mit Etherverbindungen wie Methyl-, Ethyl-, Butyl- oder Diethylenglykol bzw. deren Acetate (beispielsweise Produkte vom Typ der "Cellosolve" der Union Carbide Corp.) eingesetzt werden.Water is preferably used as the solvent for the detergents according to the invention. However, organic solvents can also be used in amounts of up to 20, preferably up to 16,% by weight of the total liquid detergent. Such additional solvents are either lower alkanols or lower diols or polyols such as ethanol, isopropyl alcohol, ethylene glycol, propylene glycol or glycerin. If appropriate, polyols with ether compounds such as methyl, ethyl, butyl or diethylene glycol or their acetates (for example products of the "Cellosolve" type from Union Carbide Corp.) can also be used.

Zur Verbesserung der Löslichkeit der Tenside ist es häufig zweckmäßig, zusätzlich oder anstelle der zuvor genannten organischen Lösungsmittel Lösungsvermittler, sogenannte Hydrotrope, zu verwenden. Die bevorzugten Hydrotrope sind nichttensidische organische Sulfonate, wie z.B. C6-C10-Alkansulfonate, sowie die Salze.der Toluol-, Xylol-und Cumolsulfonsäure, vorzugsweise deren Alkanolamin- und Alkalisalze, insbesondere deren Kaliumsalze. Auch Harnstoff ist als Hydrotrop geeignet. Hydrotrope werden in Mengen von 2 bis 12, vorzugsweise 3 bis 9 Gew.-%, bezogen auf das gesamte Flüssigwaschmittel, zugesetzt.To improve the solubility of the surfactants, it is often advisable to use solubilizers, so-called hydrotropes, in addition to or instead of the organic solvents mentioned above. The preferred hydrotropes are non-surfactant organic sulfonates, such as, for example, C 6 -C 10 -alkanesulfonates, and the salts of toluene, xylene and cumene sulfonic acid, preferably their alkanolamine and alkali salts, in particular their potassium salts. Urea is also suitable as a hydrotrope. Hydrotropes are added in amounts of 2 to 12, preferably 3 to 9,% by weight, based on the total liquid detergent.

Zur Verbesserung bestimmter Eigenschaften können den erfindungsgemäßen Waschmitteln weitere, ebenfalls meist in geringen Mengen wirksame Hilfsstoffe zugesetzt werden; dies sind beispielsweise Trübungs- und Viskositätsstellmittel, die meist zu etwa 0,05 bis 2 Gew.-% in dem Waschmittel enthalten sind. Hierbei handelt es sich z.B. um Ester von Alkanolen oder Partialester von Polyolen mit längerkettigen Fettsäuren, wie z.B. Palmitin- oder Stearinsäure. Ein typisches Produkt ist Ethylenglykolstearat.To improve certain properties, further auxiliaries, which are likewise usually active in small amounts, can be added to the detergents according to the invention; These are, for example, opacifiers and viscosity regulators, which are usually contained in the detergent at about 0.05 to 2% by weight. This is e.g. around esters of alkanols or partial esters of polyols with longer chain fatty acids, e.g. Palmitic or stearic acid. A typical product is ethylene glycol stearate.

Als Konservierungsmittel wird meist Formalin in einer Menge von 0,05 bis 1 Gew.-% verwendet.Formalin is usually used as a preservative in an amount of 0.05 to 1% by weight.

Zur Vermeidung von Verfärbungen der Waschmittel bei längerer Lagerung, die durch Verunreinigungen z.B. mit Schwermetallionen bei der Herstellung hervorgerufen werden können, setzt man Komplexierungsmittel für Schwermetallionen zu. Gebräuchliche Komplexierungsmittel sind die Natrium-, Kalium- oder Triethanolaminsalze von Aminopolycarbonsäuren, wie beispielsweise Ethylendiamintetraessigsäure oder Nitrilotriessigsäure. Sie werden in Mengen von 0,1 bis 1 Gew.-% eingesetzt.In order to avoid discoloration of the detergents during prolonged storage, which can be caused by contamination, for example with heavy metal ions, in the production, complexing agents for heavy metal ions are added. Common complexing agents are the sodium, potassium or triethanolamine salts of aminopolycarboxylic acids, such as, for example, ethylenediaminetetraacetic acid or nitrilotriacetic acid. They are used in amounts of 0.1 to 1% by weight.

Als Duftstoffe kommen beispielsweise Stoffe mit blumig/frischer oder fruchtiger oder als kosmetisch oder cremig bezeichneter Duftnote in Frage.Examples of suitable fragrances are substances with a floral / fresh or fruity fragrance or those designated as cosmetic or creamy.

Geeignete Farbstoffe sind z.B. wasserlösliche rote Xanthen-Farbstoffe, wie Rhodamin B extra.Suitable dyes are e.g. water-soluble red xanthene dyes, such as rhodamine B extra.
