Description

Die Erfindung betrifft ein Aldehyd-haltiges Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel mit antibakterieller Wirkung, umfassend elementares Silber und/oder eine Silberverbindung. Die Erfindung betrifft auch die Verwendung sowie ein Verfahren zur Herstellung eines solchen Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittels.The invention relates to an aldehyde-containing washing, cleaning, aftertreatment or washing aid having an antibacterial effect, comprising elemental silver and / or a silver compound. The invention also relates to the use and a method for producing such a washing, cleaning, aftertreatment or washing aid.

Die Anhaftung von Mikroorganismen an Oberflächen ist, insbesondere bei pathogenen Mikroorganismen, unerwünscht. Anhaftende Mikroorganismen führen häufig zu Infektionen bzw. zur Reinfektion bei Mensch, Tier und Pflanzen.The adhesion of microorganisms to surfaces is undesirable, especially in pathogenic microorganisms. Adherent microorganisms often lead to infections or reinfection in humans, animals and plants.

Immer häufiger werden empfindliche Textilien, wie zum Beispiel Seide oder Mikrofaser, zu Kleidungsstücken verarbeitet, die nur bei 30 oder 40 °C gewaschen werden können. Dadurch werden Pilze, wie beispielsweise die humanpathogene Candida albicans, nicht abgetötet.Increasingly, delicate textiles, such as silk or microfiber, are processed into garments that can only be washed at 30 or 40 ° C. As a result, fungi, such as the human pathogenic Candida albicans, are not killed.

Neben der niedrigeren Waschtemperatur ist jedoch heutzutage auch die Verwendung flüssiger Waschmittel üblich, die in der Regel frei von Bleichmitteln sind. Bei einer 60 °C-Wäsche, wie sie früher die Regel war, wurden zuverlässig nahezu alle Keime vernichtet, zum einen durch die höhere Temperatur, zum anderen durch die in den üblicherweise verwendeten Universalwaschmitteln enthaltenen Bleichmittel.In addition to the lower washing temperature, however, the use of liquid detergents which are generally free of bleaching agents is customary today. In a 60 ° C wash, as was the rule in the past, almost all germs were reliably destroyed, on the one hand by the higher temperature, and on the other by the bleach contained in the commonly used universal detergents.

Somit können durch das veränderte Waschverhalten mit Viren, Bakterien, Schimmel- oder Hefepilzen verunreinigte Textilien nicht im erforderlichen Maße keimfrei gemacht werden, so dass unter Umständen eine (Re-)Infektion beim erneuten Kontakt des Verbrauchers mit der vermeintlich reinen Wäsche erfolgen kann.Thus contaminated textiles can not be sterilized to the required extent by the changed washing behavior with viruses, bacteria, mold or yeast fungi, so that under certain circumstances a (re-) infection can occur during renewed contact of the consumer with the supposedly pure laundry.

Daneben können auch Probleme mit Schlechtgerüchen auftreten, weil sich Restkeime beim Trocknen, Tragen oder Lagern auf der Wäsche vermehren und schlecht riechende Stoffwechselprodukte produzieren. Außerdem kann im Inneren einer Waschmaschine selber durch anhaftende Biofilme ein schlechter Geruch hervorgerufen werden.In addition, problems with bad odors can occur because residual germs multiply when drying, carrying or storing on the laundry and produce bad-smelling metabolites. In addition, inside a washing machine itself can be caused by adhering biofilms a bad smell.

Antimikrobiell wirksame Zusammensetzungen und ihr Einsatz in Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmitteln sind im Stand der Technik bekannt. Häufig handelt es sich bei den eingesetzten Desinfektionsmitteln um halogenhaltige Stoffe oder Phenolderivate oder andere aromatische Kohlenwasserstoffe, die aus Gründen der Umweltverträglichkeit als problematisch angesehen werden können. Andere, verträglichere Mikrobiozide haben nur ein eingeschränktes Wirkungsspektrum oder sind nur unter bestimmten physikalischen Bedingungen wirksam. Für Anwendungen im Haushalt besteht aber ein hoher Bedarf an antimikrobiellen Zusammensetzungen, die gegen ein breites Spektrum an Mikroorganismen wirksam und dabei umweltschonend sind; natürliche Bestandteile sind ebenfalls wünschenswert.Antimicrobially active compositions and their use in washing, cleaning, aftertreatment or washing aids are known in the art. Frequently, the disinfectants used are halogen-containing substances or phenol derivatives or other aromatic hydrocarbons, which can be regarded as problematic for reasons of environmental compatibility. Other, more compatible microbicides have only a limited spectrum of activity or are effective only under certain physical conditions. For household applications, however, there is a high demand for antimicrobial Compositions that are effective against a broad spectrum of microorganisms while being environmentally friendly; Natural ingredients are also desirable.

Silber bzw. Silberionen üben unter anderem eine blockierende Wirkung auf Thiol-Enzyme in Mikroorganismen aus und besitzen so eine hohe bakterizide und fungizide Wirkung. Darüber hinaus wirkt Silber keimtötend. Im Stand der Technik sind deshalb, beispielsweise aus der EP 1670885 A1 , bereits keimreduzierende Wasch-oder Reinigungsmittel, enthaltend Silber und/oder Silberionen bekannt.Among other things, silver or silver ions have a blocking effect on thiol enzymes in microorganisms and thus have a high bactericidal and fungicidal action. In addition, silver has a germicidal effect. In the prior art, therefore, for example, from the EP 1670885 A1 , already germ-reducing detergents or cleaners containing silver and / or silver ions known.

Oftmals sind Zusammensetzungen, die Silber und/oder Silberionen enthalten, nicht stabil, denn die in den Mitteln enthaltenen Silberionen können mit Verunreinigungen, wie Chlorid-Ionen zu lichtempfindlichen Silberchlorid-Salzen oder wie Sulfid zu schlecht löslichen Silbersulfid-Salzen reagieren. In einem (stark) alkalischen Medium können lösliche Silberionen zunächst zu AgOH und dann weiter zu schwerlöslichem Ag2O reagieren. Neben der Schwerlöslichkeit dieser Silbersalze bewirken insbesondere die Silberoxide und Silbersulfide trotz geringer Mengen erhebliche Farbveränderungen, insbesondere eine Braun- oder Schwarzfärbung, der Zusammensetzung.Often compositions containing silver and / or silver ions are not stable because the silver ions contained in the agents can react with impurities such as chloride ions to photosensitive silver chloride salts or as sulfide to poorly soluble silver sulfide salts. In a (strongly) alkaline medium, soluble silver ions can first react to AgOH and then further to sparingly soluble Ag 2 O. In addition to the poor solubility of these silver salts, in particular the silver oxides and silver sulfides cause considerable color changes, in particular a brown or black color, of the composition despite small amounts.

Ein weiteres Problem kann sich bei Gegenwart von Aldehyden ergeben, da diese von Silberionen oxidiert werden können. Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel enthalten oftmals ein Parfümöl. Viele Parfümöle enthalten Riechstoffe der Klasse der Aldehyde. Eine Oxidation dieser Aldehyde führt jedoch zu einem unerwünschten, veränderten Dufteindruck.Another problem can arise in the presence of aldehydes, since these can be oxidized by silver ions. Washing, cleaning, aftertreatment or washing aids often contain a perfume oil. Many perfume oils contain fragrances of the class of aldehydes. Oxidation of these aldehydes, however, leads to an undesirable, altered fragrance impression.

Eine Aufgabe dieser Erfindung war daher, die Bereitstellung eines stabilen, Aldehyd-haltigen Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittels mit antibakterieller Wirkung.An object of this invention was therefore to provide a stable, aldehyde-containing washing, cleaning, aftertreatment or washing aid with antibacterial activity.

Diese Aufgabe wird gelöst durch ein Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel, umfassend ein

  1. (a) elementares Silber und/oder eine Silberverbindung,
  2. (b) eine Aldehydverbindung und
  3. (c) Wasserstoffperoxid.
This object is achieved by a washing, cleaning, aftertreatment or washing aid comprising a
  1. (a) elemental silver and / or a silver compound,
  2. (b) an aldehyde compound and
  3. (c) hydrogen peroxide.

Überraschenderweise hat sich gezeigt, dass durch die Gegenwart von Wasserstoffperoxid eine Stabilisierung des elementaren Silbers und/oder des Silberkations der Silberverbindung erreicht werden kann, ohne dass eine Beeinträchtigung der keimtötenden Wirkung oder des Dufteindrucks des Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittels auftritt.Surprisingly, it has been shown that stabilization of the elemental silver and / or the silver cation of the silver compound can be achieved by the presence of hydrogen peroxide without impairing the germicidal effect or the fragrance impression of the washing, cleaning, after-treatment or washing assistant.

Der Dufteindruck eines Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittels selber sowie der Dufteindruck, den ein Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel bei einem damit behandelten Textil hintertässt, ist oftmals ein entscheidender Faktor für die Kaufentscheidung von Konsumenten. Die aufgeführten Aldehyd-Verbindungen sind übliche und häufig eingesetzte Riechstoffe, die entscheidend zum Dufteindruck einer Parfümzusammensetzung beitragen.The scent impression of a washing, cleaning, aftertreatment or washing aid itself as well as the scent impression, which hinders a washing, cleaning, aftertreatment or washing aid in a textile treated with it, is often a decisive factor for the buying decision of consumers. The listed aldehyde compounds are customary and frequently used fragrances, which contribute decisively to the fragrance impression of a perfume composition.

Es kann bevorzugt sein, dass das Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel zusätzlich 0,01 bis 3 Gew.%, bezogen auf das gesamte Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel, Ammoniumhydroxid enthält. Überraschenderweise hat sich gezeigt, dass besonders klare und somit ästhetisch ansprechende Zusammensetzungen durch Zugabe bereits geringer Mengen an Ammoniumhydroxid erhalten werden.It may be preferred that the washing, cleaning, aftertreatment or washing aid additionally contains 0.01 to 3 wt.%, Based on the total washing, cleaning, aftertreatment or washing aid, ammonium hydroxide. Surprisingly, it has been found that particularly clear and thus aesthetically pleasing compositions are obtained by adding even small amounts of ammonium hydroxide.

Die Erfindung betrifft auch die Verwendung eines erfindungsgemäßen Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittels beim Waschen, Reinigen, Vorbehandeln und/oder Konditionieren von Textilien.The invention also relates to the use of a washing, cleaning, aftertreatment or washing aid according to the invention in the washing, cleaning, pretreatment and / or conditioning of textiles.

Ferner betrifft die Erfindung auch ein Verfahren zur Herstellung eines Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittels, umfassend (a) eine Aldehyd-Verbinung und (b) elementares Silber und/oder eine Silberverbindung, bei dem die Aldehyd-Verbindung und das elementare Silber und/oder die Silberverbindung mittels einer Parfümzusammensetzung, welche zusätzlich Wasserstoffperoxid enthält, zugesetzt werden.Furthermore, the invention also relates to a process for the preparation of a washing, cleaning, aftertreatment or washing aid, comprising (a) an aldehyde compound and (b) elemental silver and / or a silver compound, wherein the aldehyde compound and the elemental Silver and / or the silver compound can be added by means of a perfume composition which additionally contains hydrogen peroxide.

Parfümzusammensetzungen werden üblicherweise am Ende eines Herstellungsverfahrens von Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmitteln zugesetzt. Durch Zugabe des elementaren Silbers und/oder der Silberverbindungen mit der Parfümzusammensetzung erfolgt eine Spezialisierung des hergestellten Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittels in ein antibakteriell wirksames Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel auch erst spät im Herzustellungsprozess und ein Ansatz kann verwendet werden, um verschiedenste Kategorien an Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmitteln herzustellen. Außerdem können über die Parfümzusammensetzung auf einfache und schnelle Weise geringste Menge an Aldehyd-Verbindung, Wasserstoffperoxid, elementarem Silber und/oder Silberverbindung einem Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel zugesetzt werden.Perfume compositions are usually added at the end of a manufacturing process of washing, cleaning, aftertreatment or washing aids. By adding the elemental silver and / or the silver compounds with the perfume composition, a specialization of the washing, cleaning, aftertreatment or washing aid in an antibacterial detergent, cleaning, aftertreatment or washing aid also takes place late in the preparation process and an approach can be used to produce various categories of washing, cleaning, after-treatment or washing aids. In addition, the perfume composition can be used to easily and quickly add the least amount of aldehyde compound, hydrogen peroxide, elemental silver and / or silver compound to a washing, cleaning, after-treatment or washing assistant.

Die Erfindung betrifft auch die Verwendung von Wasserstoffperoxid zur Stabilisierung einer Aldehyd-haltigen Zusammensetzung, die Silber und/oder einer Silberverbindung umfasst.The invention also relates to the use of hydrogen peroxide to stabilize an aldehyde-containing composition comprising silver and / or a silver compound.

Ebenso betrifft die Erfindung eine Parfümzusammensetzung, vorzugsweise zur Verwendung in einem Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel, umfassend (a) elementares Silber und/oder eine Silberverbindung, (b) eine Aldehyd-Verbindung und (c) Wasserstoffperoxid.The invention also relates to a perfume composition, preferably for use in a washing, cleaning, after-treatment or washing aid, comprising (a) elemental silver and / or a silver compound, (b) an aldehyde compound and (c) hydrogen peroxide.

Im Folgenden soll die Erfindung, unter anderem anhand von Beispielen, eingehender erläutert werden.In the following, the invention will be explained in more detail, inter alia, by way of examples.

Als einen essentiellen Bestandteil enthält das Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel elementares Silber und/oder eine Silberverbindung.As an essential ingredient, the washing, cleaning, after-treatment or washing aid contains elemental silver and / or a silver compound.

Erfindungsgemäß wird Silber entweder in elementarer Form oder in Form seiner Verbindungen eingesetzt. Wird das Silber in elementarer Form eingesetzt, so weist es vorzugsweise Partikelgrößen von 1 nm bis 100 µm auf. Noch feinere Partikelgrößen des Silbers lassen sich durch Einsatz des elementaren Silbers in kolloidaler Form erreichen, wobei das Silber Partikelgrößen von 0,001 bis 0,1 µm aufweist.According to the invention, silver is used either in elemental form or in the form of its compounds. If the silver is used in elemental form, it preferably has particle sizes of 1 nm to 100 μm. Even finer particle sizes of silver can be achieved by using the elemental silver in colloidal form, wherein the silver has particle sizes of 0.001 to 0.1 microns.

Es ist allerdings bevorzugt, dass das Mittel eine Silberverbindung enthält und diese Silberverbindung ausgewählt ist aus der Gruppe bestehend aus Silberacetat, Silbercitrat, Silberdiaminchlorid-Komplex, Silbercyclodextrin-Komplex, Silberdicyanokalium-Komplex, Silberphthalimid, Silberphenylcyanamid, Silber(ethylenthioharnstoff)-Komplex, Silberimidazolat, Übergangsmetall-NHC-Calix[4]aren-Komplexe, Silber-Kronenether, Silbernitrat, Silberchlorid auf einem Trägermaterial und Mischungen daraus. Die Silberverbindungen werden vorzugsweise in Form von Lösungen, Suspensionen oder Dispersionen eingesetzt. Besonders bevorzugt enthält das Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel Silbernitrat, welches in Form einer wässrigen Lösung eingesetzt wird, oder Silberchlorid auf Titandioxid als Trägermaterial, welches als wässrige Dispersion eingesetzt wird.However, it is preferred that the agent contains a silver compound and that silver compound is selected from the group consisting of silver acetate, silver citrate, silver diamine chloride complex, silver cyclodextrin complex, silver dicyanokalium complex, silver phthalimide, silver phenylcyanamide, silver (ethylene thiourea) complex, silver imidazolate, Transition metal NHC-calix [4] arene complexes, silver crown ethers, silver nitrate, silver chloride on a support material and mixtures thereof. The silver compounds are preferably used in the form of solutions, suspensions or dispersions. Particularly preferably, the washing, cleaning, aftertreatment or washing aid contains silver nitrate, which in the form an aqueous solution is used, or silver chloride on titanium dioxide as a carrier material, which is used as an aqueous dispersion.

Die Menge an elementarem Silber und/oder Silberverbindung beträgt vorzugsweise 0,0001 bis 1 Gew.-% und mehr bevorzugt zwischen 0,001 und 0,25 Gew.%, bezogen auf das gesamte Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel. Ganz besonders bevorzugte Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel enthalten 0,001 bis 0,1 Gew.-% an elementarem Silber und/oder einer Silberverbindung, bezogen auf das gesamte Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel.The amount of elemental silver and / or silver compound is preferably from 0.0001 to 1% by weight, and more preferably from 0.001 to 0.25% by weight, based on the total washing, cleaning, after-treatment or washing aid.

Es ist bevorzugt, dass der Aldehyd ein Bestandteil einer Parfümzusammensetzung ist und so in das Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel gelangt.It is preferred that the aldehyde is a component of a perfume composition and thus enters the washing, cleaning, aftertreatment or washing aid.

Die Menge an Aldehyd-Verbindung kann zwischen 0,001 und 5 Gew.-% bezogen auf das gesamte Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel betragen.The amount of aldehyde compound may be between 0.001 and 5 wt .-% based on the total washing, cleaning, aftertreatment or washing aid.

Unter bestimmten Bedingungen können die eingesetzten Aldehyde die Primärleistung des keimabtötenden Mittels, hier elementares Silber oder eine Silberverbindung, unterstützen, dass heißt selbst eine antibakterielle/keimabtötende Wirkung aufweisen.Under certain conditions, the aldehydes used, the primary performance of germicidal agent, here elemental silver or a silver compound, support, that is, even have an antibacterial / germicidal effect.

Die Parfümzusammensetzung kann neben einer oder mehr Aldehyd-Verbindung(en) weitere Riechstoffverbindungen, wie zum Beispiel die synthetischen Produkte vom Typ der Ester, Ether, Ketone, Alkohole und Kohlenwasserstoffe enthalten. Bevorzugt werden Mischungen verschiedener Riechstoffe verwendet, die gemeinsam eine ansprechende Duftnote erzeugen. Eine Parfümzusammensetzung kann auch natürliche Riechstoffgemische enthalten, wie sie aus pflanzlichen Quellen zugänglich sind. Daneben kann die Parfümzusammensetzung organische Lösungsmittel und/oder Tenside umfassen.The perfume composition may contain, in addition to one or more aldehyde compound (s), other perfume compounds such as ester type synthetic products, ethers, ketones, alcohols, and hydrocarbons. Preferably, mixtures of different fragrances are used, which together produce an attractive fragrance. A perfume composition may also contain natural fragrance mixtures as available from plant sources. In addition, the perfume composition may comprise organic solvents and / or surfactants.

Als dritten essentiellen Bestandteil enthält die Zusammensetzung Wasserstoffperoxid. Die Menge an Wasserstoffperoxid beträgt bevorzugt zwischen 0,01 und 5 Gew.-% und ganz bevorzugt zwischen 0,1 und 2,5 Gew.-%.As the third essential ingredient, the composition contains hydrogen peroxide. The amount of hydrogen peroxide is preferably between 0.01 and 5 wt .-%, and more preferably between 0.1 and 2.5 wt .-%.

Das Wasserstoffperoxid dient in den Aldehyd- und Silber-haltigen Mitteln quasi als "Opferanode" und verhindert unerwünschte Reaktionen zwischen den Aldehyden und der Silberverbindung. Insbesondere verhindert das Wasserstoffperoxid eine Oxidation der Aldehyde durch die Silberverbindungen. Überraschenderweise hat sich herausgestellt, dass das Wasserstoffperoxid keine unerwünschten Reaktionen mit den weiteren Bestandteilen, beispielsweise den Riechstoffverbindungen, der Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel, eingeht.The hydrogen peroxide serves as a "sacrificial anode" in the aldehyde- and silver-containing agents and prevents undesired reactions between the aldehydes and the silver compound. In particular, the hydrogen peroxide prevents oxidation of the aldehydes by the silver compounds. Surprisingly, it has been found that the hydrogen peroxide does not undergo any undesired reactions with the other constituents, for example the perfume compounds, the washing, cleaning, after-treatment or washing auxiliaries.

Zusätzlich zu dem elementaren Silber bzw. der Silberverbindung, der Aldehyd-Verbindung und dem Wasserstoffperoxid kann das Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel weitere Inhaltsstoffe enthalten, die die anwendungstechnischen und/oder ästhetischen Eigenschaften des Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittels weiter verbessern.

Das Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel enthält vorzugsweise 1 bis 60 Gew.-% eines Tensids ausgewählt aus der Gruppe bestehend aus anionischen, nichtionischen, kationischen und zwitterionischen Tenside sowie Mischungen daraus.The washing, cleaning, aftertreatment or washing aid preferably contains 1 to 60 wt .-% of a surfactant selected from the group consisting of anionic, nonionic, cationic and zwitterionic surfactants and mixtures thereof.

Geeignete nichtionische Tenside umfassen alkoxylierte Fettalkohole, alkoxylierte Fettsäurealkylester, Fettsäureamide, alkoxylierte Fettsäureamide, Polyhydroxyfettsäureamide, Alkylphenolpolyglycolether und Mischungen daraus.Suitable nonionic surfactants include alkoxylated fatty alcohols, alkoxylated fatty acid alkyl esters, fatty acid amides, alkoxylated fatty acid amides, polyhydroxy fatty acid amides, alkylphenol polyglycol ethers, and mixtures thereof.

Als nichtionische Tenside werden vorzugsweise alkoxylierte, vorteilhafterweise ethoxylierte, insbesondere primäre Alkohole mit vorzugsweise 8 bis 18 C-Atomen und durchschnittlich 1 bis 12 Mol Ethylenoxid (EO) pro Mol Alkohol eingesetzt, in denen der Alkoholrest linear oder bevorzugt in 2-Stellung methylverzweigt sein kann bzw. lineare und methylverzweigte Reste im Gemisch enthalten kann, so wie sie üblicherweise in Oxoalkoholresten vorliegen. Insbesondere sind jedoch Alkoholethoxylate mit linearen Resten aus Alkoholen nativen Ursprungs mit 12 bis 18 C-Atomen, zum Beispiel aus Kokos-, Palm-, Talgfett- oder Oleylalkohol, und durchschnittlich 2 bis 8 EO pro Mol Alkohol bevorzugt. Zu den bevorzugten ethoxylierten Alkoholen gehören beispielsweise C12-14-Alkohole mit 3 EO, 4 EO oder 7 EO, C9-11-Alkohol mit 7 EO, C13-15-Alkohole mit 3 EO, 5 EO, 7 EO oder 8 EO, C12-18-Alkohole mit 3 EO, 5 EO oder 7 EO und Mischungen aus diesen, wie Mischungen aus C12-14-Alkohol mit 3 EO und C12-18-Alkohol mit 7 EO. Die angegebenen Ethoxylierungsgrade stellen statistische Mittelwerte dar, die für ein spezielles Produkt eine ganze oder eine gebrochene Zahl sein können. Bevorzugt Alkoholethoxylate weisen eine eingeengte Homologenverteilung auf (narrow range ethoxylates, NRE). Zusätzlich zu diesen nichtionischen Tensiden können auch Fettalkohole mit mehr als 12 EO eingesetzt werden. Beispiele hierfür sind Talgfettalkohol mit 14 EO, 25 EO, 30 EO oder 40 EO. Auch nichtionische Tenside, die EO- und PO-Gruppen zusammen im Molekül enthalten, sind erfindungsgemäß einsetzbar. Geeignet sind ferner auch eine Mischung aus einem (stärker) verzweigten ethoxylierten Fettalkohol und einem unverzweigten ethoxylierten Fettalkohol, wie beispielsweise eine Mischung aus einem C16-18-Fettalkohol mit 7 EO und 2-Propylheptanol mit 7 EO. Insbesondere bevorzugt enthält das Wasch-, Reinigungs-, Nachbehandlungs- oder Waschhilfsmittel einen C12-18-Fettalkohol mit 7 EO oder einen C13-15-Oxoalkohol mit 7 EO als nichtionisches Tensid.The nonionic surfactants used are preferably alkoxylated, advantageously ethoxylated, in particular primary, alcohols having preferably 8 to 18 carbon atoms and on average 1 to 12 moles of ethylene oxide (EO) per mole of alcohol, in which the alcohol radical can be linear or preferably methyl-branched in the 2-position or linear and methyl-branched radicals in the mixture can contain, as they are usually present in Oxoalkoholresten. In particular, however, alcohol ethoxylates with linear radicals of alcohols of native origin having 12 to 18 carbon atoms, for example of coconut, palm, tallow or oleyl alcohol, and on average 2 to 8 EO per mole of alcohol are preferred. The preferred ethoxylated alcohols include, for example, C 12-14 alcohols with 3 EO, 4 EO or 7 EO, C 9-11 alcohols with 7 EO, C 13-15 alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C 12-18 -alcohols with 3 EO, 5 EO or 7 EO and mixtures of these, such as mixtures of C 12-14 -alcohol with 3 EO and C 12-18 -alcohol with 7 EO. The degrees of ethoxylation given represent statistical means which, for a particular product, may be an integer or a fractional number. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these nonionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples include tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO. Nonionic surfactants containing EO and PO groups together in the molecule can also be used according to the invention. Also suitable are also a mixture of a (more) branched ethoxylated fatty alcohol and an unbranched ethoxylated fatty alcohol, such as a mixture of a C 16-18 fatty alcohol with 7 EO and 2-propylheptanol with 7 EO. Particularly preferably, the washing, cleaning, aftertreatment or washing aid contains a C 12-18 fatty alcohol with 7 EO or a C1 3-15 -Oxoalkohol with 7 EO as a nonionic surfactant.
