Abstract

In Waschmitteln, die nichtionische Tenside enthalten, werden folgende farbübertragungsinhibierenden Farbfixiermittel eingesetzt: Umsetzungsprodukte aus a) Aminen mit Epichlorhydrin oder, b) Cyanamid mit Aminen und Aldehyden.The following dye transfer-inhibiting color fixatives are used in detergents which contain nonionic surfactants: reaction products of a) amines with epichlorohydrin or, b) cyanamide with amines and aldehydes.

Description

Gegenstand der Erfindung sind Waschmittel und Wäschebehandlungsmittel enthaltend ein oder mehrere nichtionische Tenside und ein farbübertragungsinhibierendes Farbfixiermittel, wobei dieses Farbfixiermittel erhalten wird durch Umsetzung von

  • a) Aminen mit Epichlorhydrin
    oder
  • b) Cyanamid mit Aminen und Formaldehyd
    • The invention relates to detergents and laundry treatment compositions comprising one or more nonionic surfactants and an ink transfer-inhibiting color fixative, this color fixative being obtained by reacting
  • a) Amines with epichlorohydrin
    or
  • b) cyanamide with amines and formaldehyde

    • Die eingesetzten Amine können primäre, sekundäre und tertiare Amine sein. Dabei kann es sich um aliphatische Amine, alicyclische Amine wie z.B. Cyclohexylamin und aromatische Amine wie z.B. Anilin handeln. Die verwendeten Amine können aber auch gleichzeitig aliphatische, alicyclische und aromatische Substituenten besitzen. Ferner können auch heterocyclische Verbindungen wie z.B. Pyridin eingesetzt werden.
    Die Amine umfassen hierbei auch Polyamine z.B. Diamine, Triamine, Tetraamine u.s.w.
    Beispiele hierfür sind Ethylendiamin, Propylendiamin, Butylendiamin, Pentylendiamin, Hexylendiamin, Diethylentriamin, Triethylentetramin und höhere Polymamine. Besonders bevorzugt ist Diethylentriamin.
    Bei den Cyanamiden kann es sich um Cyanamid oder um Dicyandiamid handeln. Aldehyde, die zur Synthese der farübertragungsinhibierenden Farbfixiermittel eingesetzt werden können, sind zum Beispiel aliphatische Aldehyde wie z.B. Formaldehyd, Acetaldehyd, Propionaldehyd, Butyraldehyd; Dialdehyde wie z.B. Glyoxal; ungesättigte Aldehyde wie z.B. Acrolein, Crotonaldehyd und aromatische Aldehyde wie z.B. Benzaldehyd. Besonders bevorzugt sind die aliphatischen Aldehyde.     The amines used can be primary, secondary and tertiary amines. These can be aliphatic amines, alicyclic amines such as cyclohexylamine and aromatic amines such as aniline. However, the amines used can also have aliphatic, alicyclic and aromatic substituents at the same time. Heterocyclic compounds such as pyridine can also be used.
    The amines here also include polyamines, for example diamines, triamines, tetraamines, etc
    Examples of these are ethylenediamine, propylenediamine, butylenediamine, pentylenediamine, hexylenediamine, diethylenetriamine, triethylenetetramine and higher polymamines. Diethylene triamine is particularly preferred.
    The cyanamides can be cyanamide or dicyandiamide. Aldehydes which can be used for the synthesis of the color-transfer-inhibiting color fixing agents are, for example, aliphatic aldehydes such as, for example, formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde; Dialdehydes such as glyoxal; unsaturated aldehydes such as acrolein, crotonaldehyde and aromatic aldehydes such as benzaldehyde. The aliphatic aldehydes are particularly preferred.

    Diese Farbfixiermittel werden den erfindungsgemäßen Waschmitteln zugesetzt um die Waschechtheit der Textilfarbstoffe zu verbessern, indem sie deren Ausbluten reduzieren.
    Gleichzeitig wirken diese Farbfixiermittel auch farbübertragungsinhibierend, indem sie bei sehr schlechten Waschechtheiten der gefärbten Textilien Restmengen von ausblutendem Farbstoff in der Waschlauge binden und so eine Ablagerung auf mitgewaschenem weißen oder andersfarbigen Gewebe verhindern.    These color fixing agents are added to the detergents according to the invention in order to improve the wash fastness of the textile dyes by reducing their bleeding.
    At the same time, these color fixatives also inhibit color transfer by binding residual amounts of bleeding-out dye in the wash liquor in the case of very poor fastness to washing of the dyed textiles and thus preventing deposition on washed-off white or differently colored fabric.

    Die Waschmittelformulierungen, in denen die beschriebenen farbübertragungsinhibierenden Farbfixiermittel eingesetzt werden können, sind pulver-, granulat-, pasten-, gelförmig oder flüssig. Beispiele hierfür sind Vollwaschmittel, Feinwaschmittel, Colorwaschmittel, Wollwaschmittel, Gardinenwaschmittel, Baukastenwaschmittel, Waschtabletten, bar soaps, Waschmittelformulierungen in wasserlöslichen Folien verpackt und Fleckensalze. Wäschebehandlungsmittel sind z.B. Wäschestärken und -steifen sowie Bügelhilfen.
    Außerdem können die genannten farbübertragungsinhibierenden Farbfixiermittel in Wäschevor- bzw. Wäschenachbehandlungsmitteln eingesetzt werden, die vor bzw. nach dem eigentlichen Waschgang zur Anwendung kommen können und die ausschließlich der Wäschepflege und der Wäschekonditionierung, aber nicht der Reinigung der Wäsche dienen.    The detergent formulations in which the dye transfer-inhibiting dye-fixing agents described can be used are powder, granule, paste, gel or liquid. Examples of these are heavy-duty detergents, mild detergents, color detergents, wool detergents, curtain detergents, modular detergents, washing tablets, bar soaps, detergent formulations packed in water-soluble films and stain salts. Laundry treatment agents are, for example, laundry starches and stiffeners and ironing aids.
    In addition, the dye-transfer-inhibiting dye-fixing agents mentioned can be used in laundry pretreatment or laundry aftertreatment agents which can be used before or after the actual washing cycle and which are used exclusively for laundry care and laundry conditioning, but not for cleaning the laundry.

    Die erfindungsgemäßen Waschmittel enthalten mindestens 0,1 %, bevorzugt zwischen 0,1 und 10 % und besonders bevorzugt 0,5 bis 5 % der beschriebenen farbübertragungsinhibierenden Farbfixiermittel. Formulierungen die als Wäschevorund/oder Wäschenachbehandlungsmittel eingesetzt werden, können zwischen 1 und 99 % der Farbfixiermittel enthalten.
    Die Formulierungen sind je nach ihrer vorgesehenen Anwendung in ihrer Zusammensetzung der Art der zu waschenden Textilien anzupassen.    The detergents according to the invention contain at least 0.1%, preferably between 0.1 and 10% and particularly preferably 0.5 to 5% of the described dye transfer-inhibiting color fixing agents. Formulations which are used as laundry pretreatment and / or laundry aftertreatment agents can contain between 1 and 99% of the color fixing agents.
    Depending on their intended use, the formulation of the formulations must be adapted to the type of textiles to be washed.

No. 3,213,030, U.S. 3,422,021, U.S. 3,400,148 and U.S. 3,422,137 are used.

    Die erfindungsgemäßen Waschmittel und Wäschebehandlungsmittel können übliche Hilfsstoffe oder andere Materialien enthalten, die die Reinigungswirkung verstärken, zur Behandlung oder Pflege des zu waschenden Textilmaterials dienen oder die Gebrauchseigenschaften der Waschmittel-zusammensetzung ändern.The detergents and laundry treatment agents according to the invention can be conventional Contain additives or other materials that enhance the cleaning effect, to treat or care for the textile material to be washed or the Change the usage properties of the detergent composition.

    Geeignete Hilfsmittel umfassen die in US-3,936,537 genannten Stoffe, beispielsweise Enzyme, insbesondere Proteasen, Lipasen, Cellulasen, Amylasen, Mannanasen, Enzymstabilisatoren, Schaumverstärker, Schaumbremsen, Anlaufund/oder Korrosionsschutzmittel, Suspensionsmittel, Farbstoffe, Füllmittel, optische Aufheller, Desinfektionsmittel, Alkalien, hydrotrope Verbindungen, Antioxidantien, Parfüme, Lösungsmittel, Lösungsvermittler, Wiederablagerungsverhinderer, Dispergiermittel, Verarbeitungshilfsmittel, Weichmacher, Antistatikhilfsmittel und Soil Release Polymere wie z.B. die TexCare-Marken/ Fa.

    Die erfindungsgemäßen Wasch- und Reinigungsmittel enthaltend farbübertragungsinhibierende Farbfixiermittel können zusätzlich auch die bekannten und kommerziell erhältlichen Farbübertragungsinhibitoren enthalten.
    Beispiele für diese Farbübertragungsinhibitoren sind Polyamin-N-oxide wie etwa Poly-(4-vinylpyridin-N-oxid), z.B. Chromabond S-400, Fa. ISP; Polyvinylpyrrolidon, z.B. Sokalan HP 50/ Fa. BASF und Copolymere von N-Vinylpyrrolidon mit N-Vinylimidazol und gegebenenfalls anderen Monomeren.
    Ein wesentlicher Nachteil der bisher kommerziell erhältlichen Farbübertragungsinhibitoren ist, daß sie nicht nur den von den Textilien abgelösten und in der Waschlauge enthalten Farbstoff binden, sondern zusätzlich auch Farbstoffe von den Textilien ablösen können und damit eine Verblassung der gewaschenen Farbgewebe fördern.
    Durch die Kombination mit den farbübertragungsinhibierend wirkenden Farbfixiermitteln kann nicht nur der farbübertragungsinhibierende Effekt der bekannten Farbübertragungsinhibitoren verbessert werden, sondern es kann zusätzlich dem durch diese Produkte geförderten Verblassen der Farbgewebe entgegengewirkt werden.    The washing and cleaning agents according to the invention containing color transfer-inhibiting color fixatives can additionally also contain the known and commercially available color transfer inhibitors.
    Examples of these color transfer inhibitors are polyamine N-oxides such as poly- (4-vinylpyridine-N-oxide), for example Chromabond S-400, from ISP; Polyvinylpyrrolidone, for example Sokalan HP 50 / BASF and copolymers of N-vinylpyrrolidone with N-vinylimidazole and optionally other monomers.
    A major disadvantage of the dye transfer inhibitors commercially available hitherto is that they not only bind the dye detached from the textiles and contained in the wash liquor, but can also detach dyes from the textiles and thus promote fading of the washed dye fabric.
    The combination with the dye-transfer-inhibiting dye fixatives not only improves the dye-transfer-inhibiting effect of the known dye-transfer inhibitors, but it can also counteract the fading of the color fabrics promoted by these products.

    Die Waschmittelzusammensetzungen der vorliegenden Erfindung können gegebenenfalls einen oder mehrere konventionelle Bleichmittel enthalten, sowie Bleichaktivatoren, Bleichkatalysatoren und geeignete Stabilisatoren. Im allgemeinen muß sichergestellt sein, daß die verwendeten Bleichmittel mit den Reinigungsmittelinhaltsstoffen verträglich sind. Konventionelle Prüfmethoden, wie etwa die Bestimmung der Bleichaktivität des fertig formulierten Reinigungsmittels in Abhängigkeit von der Lagerungszeit können für diesen Zweck verwendet werden.The detergent compositions of the present invention can optionally contain one or more conventional bleaches, and Bleach activators, bleach catalysts and suitable stabilizers. In general it must be ensured that the bleach used with the detergent ingredients are tolerated. Conventional test methods, such as the Determination of the bleaching activity of the formulated cleaning agent in Depending on the storage time can be used for this purpose.

    Die Peroxysäure kann entweder eine freie Peroxysäure sein, oder eine Kombination aus einem anorganischen Persalz, beispielsweise Natriumperborat oder Natriumpercarbonat und einem organischen Peroxysäure-Vorläufer, der zu einer Peroxysäure umgewandelt wird, wenn die Kombination des Persalzes und des Peroxysäure-Vorläufers in Wasser aufgelöst wird. Die organischen Peroxysäure-Vorläufer werden im Stand der Technik oft als Bleichaktivatoren bezeichnet. Beispiele geeigneter organischer Peroxysäuren sind offenbart in US-4,374,035, US-4,681,592, US-4,634,551, US-4,686,063, US-4,606,838 und US-4,671,891.The peroxy acid can either be a free peroxy acid or a combination from an inorganic persalt, for example sodium perborate or Sodium percarbonate and an organic peroxyacid precursor that leads to a Peroxyacid is converted when the combination of persalt and Peroxyacid precursor is dissolved in water. The organic peroxyacid precursors are often referred to as bleach activators in the prior art. Examples of suitable organic peroxyacids are disclosed in US 4,374,035, U.S. 4,681,592, U.S. 4,634,551, U.S. 4,686,063, U.S. 4,606,838 and U.S. 4,671,891.

    Beispiele für Zusammensetzungen, die zum Bleichen von Wäsche geeignet sind und die Perboratbleichmittel und Aktivatoren enthalten, werden beschrieben in US-4,412,934, US-4,536,314, US-4,681,695 und US-4,539,130.Examples of compositions suitable for bleaching laundry and containing perborate bleaches and activators are described in U.S. 4,412,934, U.S. 4,536,314, U.S. 4,681,695 and U.S. 4,539,130.

    Beispiele für Peroxysäuren, die für die Verwendung in dieser Erfindung bevorzugt sind, umfassen die Peroxydodecandisäure (DPDA), das Nonylamid der Peroxybernsteinsäure (NAPSA), das Nonylamid der Peroxyadipinsäure (NAPAA) und Decyldiperoxybernsteinsäure (DDPSA).
    Besonders bevorzugt werden in den erfindungsgemäßen Waschmitteln und Wäschebehandlungsmitteln Bleichsysteme auf Basis eines Persalzes wie Perboraten oder Pecarbonaten mit dem Bleichaktivator Tetraacetylethylendiamin (TAED) eingesetzt.
    Es ist bekannt, daß viele der vorgenannten Bleichmittel, deren Zweck die oxidative Zerstörung farbiger Anschmutzungen ist, auch eine Schädigung der Textilfarbstoffe bunter Textilien bewirken.
    Durch die Verwendung der farbübertragungsinhibierenden Farbfixiermittel kann der schädigende Einfluß der Bleichmittel auf die Textilfarbstoffe reduziert werden.    Examples of peroxyacids preferred for use in this invention include peroxydodecanedioic acid (DPDA), nonylamide of peroxysuccinic acid (NAPSA), nonylamide of peroxyadipic acid (NAPAA) and decyldiperoxysuccinic acid (DDPSA).
    Bleaching systems based on a persalt such as perborates or pecarbonates with the bleach activator tetraacetylethylene diamine (TAED) are particularly preferably used in the detergents and laundry treatment agents according to the invention.
    It is known that many of the bleaching agents mentioned above, the purpose of which is to oxidatively destroy colored soiling, also damage the textile dyes of colored textiles.
    By using the dye transfer inhibiting dye fixative, the damaging influence of the bleaching agents on the textile dyes can be reduced.

    Die erfindungsgemäßen Waschmittelzusammensetzungen können ein oder mehrere konventionelle Enzyme enthalten. Solche Enzyme sind z.B. Lipasen, Amylasen, Proteasen und Cellulasen.
    Die beschriebenen Farbfixiermittel können auch in handelsüblichen Wäscheweichspülern für die Haushaltsanwendung eingesetzt werden.

Beispiel 2: Umsetzungsprodukt aus Dicyandiamid mit Ethylendiamin und Formaldehyd.Example 2: reaction product of dicyandiamide with ethylenediamine and Formaldehyde.

    Diese farbübertragungsinhibierenden Farbfixiermittel wurden in Kombination mit verschiedenen Waschmitteln an fünf Farbgeweben auf ihren farberhaltenden Effekt hin untersucht. Gleichzeitig erfolgte die Prüfung auf eine farbübertragungsinhibierende Wirkung.These color transfer inhibiting color fixatives were used in combination with different detergents on five color fabrics for their color-preserving effect examined. At the same time, the test for an ink transfer inhibitor was carried out Effect.

    Dazu wurden zu einer Waschlauge, enthaltend 6 g/l eines Testwaschmittels (Zusammensetzungen siehe Tabellen 1 bis 3) jeweils 300 ppm der Farbfixiermittel gegeben und farbiges Baumwollgewebe zusammen mit weißem Baumwollgewebe gewaschen.
    Anschließend wurden die Gewebe mit klarem Wasser gespült, getrocknet und die dL,da,db-Werte bestimmt, aus denen sich die Farbdifferenzen delta E ergeben. Zum Vergleich wurden die Gewebe mit den Testwaschmitteln ohne Zusatz der Farbfixiermittel gewaschen. Die Waschbedingungen sind in Tabelle 4 angegeben. Insgesamt wurden fünf Waschzyklen durchgeführt.    For this purpose, 300 ppm of the color fixative were added to a wash liquor containing 6 g / l of a test detergent (for compositions, see Tables 1 to 3) and colored cotton fabric was washed together with white cotton fabric.
    The fabrics were then rinsed with clear water, dried and the dL, da, db values determined, from which the color differences delta E result. For comparison, the fabrics were washed with the test detergents without the addition of the color fixative. The washing conditions are given in Table 4. A total of five wash cycles were carried out.
