Definitions
- the present invention relates to a washing or cleaning agent with an antimicrobial effect which comprises at least glutamic acid-N, N-diacetic acid or its salts in connection with at least one biocidal quaternary ammonium compound.
- Microorganisms can represent a substantial hygienic and health problem in the household.
- the adhesion of microorganisms to surfaces is undesirable, especially in the case of pathogenic microorganisms.
- Adhering microorganisms often lead to infections or reinfections in humans, animals and also plants.
- Antimicrobially active compounds and compositions and their use in detergents are known in the prior art. For example, reveals WO 2013/064340 A1 a cleaning agent for hard surfaces with a pH in the range from 9 to 12, which comprises benzalkonium chloride, a salt of di- or tricarboxylic acids, sodium tripolyphosphate and water.
- quaternary ammonium compounds are described as microbially active compounds in liquid detergents or cleaning agents.
- a concentration-dependent effectiveness gap has been shown, in particular in the case of gram-negative bacteria. These occur in particular in damp areas, such as those prevalent in the bathroom or on damp laundry.
- US 2010227930 A1 discloses compositions with citrate and iminodisuccinate complexing agents.
- One object of the present invention is therefore to provide an antimicrobially active washing or cleaning agent with at least one quaternary ammonium compound in which the antimicrobial effectiveness is improved compared to known formulations.
- glutamic acid-N, N-diacetic acid or its salts can achieve an improved antimicrobial effect of the quaternary ammonium compounds, although the glutamic acid-N, N-diacetic acid or its salts themselves are not antimicrobial.
- a synergistic effect has been shown here between the quaternary ammonium compounds and glutamic acid-N, N-diacetic acid or its salts.
- a washing or cleaning agent Using a washing or cleaning agent according to the invention, a hygiene effect can thus be achieved even at low washing temperatures and with liquid detergents, which is comparable to the hygienic performance of bleach-containing powder detergents at higher temperatures of 60 ° C. or more.
- a predominant effectiveness gap against Pseudomonadae or other microorganisms can also be closed in this way.
- the washing or cleaning agent according to the invention has at least one tetracarboxylic acid, which according to the invention is glutamic acid-N, N-diacetic acid, or its salts (tetracarbonates).
- Tetracarboxylic acids have one of the following general structures (Ia), (Ib) or (Ic):
- the corresponding tetracarbonates accordingly preferably have the following general structures (IIa), (IIb) or (IIc):
- tetracarboxylic acid is described below, it is also to be understood accordingly to include the tetracarbonates, and vice versa.
- m, n, o and p each independently of one another represent whole natural numbers in the range from 0 to 10, in particular from 0 to 8, preferably from 1 to 6, particularly from 1 to 5, and particularly preferably for 0, 1, 2, 3 or 4, and in particular for 0, 1 or 2.
- the salt is preferably the ammonium and / or alkali metal salt, and Z + is preferably NH 4 + , Na + or K + .
- A is preferably selected from a substituted or unsubstituted alkyl or aryl radical having 2 to 14 carbon atoms, or an element of group 14, 15 or 16 of the Periodic Table (PSE). These are of course restricted according to the valence of the atoms. It is obvious to the person skilled in the art that in formula (Ia) or (IIa) A does not represent an element of the 15th or 16th group of the (PSE), as does elements of the 16th in formula (Ib) or (IIb) Group are excluded. If A has an open valence, a hydrogen atom is bound to it.

Description
Die vorliegende Erfindung betrifft ein Wasch- oder Reinigungsmittel mit antimikrobieller Wirkung, welches wenigstens Glutaminsäure-N,N-diessigsäure oder deren Salze in Verbindung mit wenigstens einer bioziden quarternären Ammoniumverbindung umfasst.The present invention relates to a washing or cleaning agent with an antimicrobial effect which comprises at least glutamic acid-N, N-diacetic acid or its salts in connection with at least one biocidal quaternary ammonium compound.
Mikroorganismen können ein substantielles hygienisches und gesundheitliches Problem im Haushalt darstellen. Die Anhaftung von Mikroorganismen an Oberflächen ist, insbesondere bei pathogenen Mikroorganismen, unerwünscht. Anhaftende Mikroorganismen führen häufig zu Infektionen beziehungsweise zu Reinfektionen bei Menschen, Tieren und auch Pflanzen.Microorganisms can represent a substantial hygienic and health problem in the household. The adhesion of microorganisms to surfaces is undesirable, especially in the case of pathogenic microorganisms. Adhering microorganisms often lead to infections or reinfections in humans, animals and also plants.
Immer häufiger werden empfindliche Textilien, wie beispielsweise Seide oder Mikrofasern, zu Kleidungsstücken verarbeitet, die nur bei 30 °C oder 40 °C gewaschen werden können. Mikroorganismen werden bei solchen Temperaturen nicht sicher abgetötet. Neben den niedrigeren Waschtemperaturen ist es heutzutage auch üblich, flüssige Waschmittel zu verwenden, die in der Regel frei von Bleichmittel sind, welche antimikrobiell wirksam sind. Zudem können auch Probleme mit Schlechtgerüchen auftreten, weil sich Restkeime beim Trocknen, Tragen oder Lagern auf der Wäsche vermehren und schlecht riechende Stoffwechselprodukte produzieren.More and more sensitive textiles, such as silk or microfibres, are being processed into garments that can only be washed at 30 ° C or 40 ° C. Microorganisms are not safely killed at such temperatures. In addition to the lower washing temperatures, it is now common to use liquid detergents, which are usually free from bleach, which are antimicrobial. In addition, problems with bad smells can arise because residual germs multiply when drying, wearing or storing clothes on the laundry and produce bad smelling metabolic products.
Das Problem der Anhaftung von Mikroorganismen besteht jedoch nicht nur auf Bekleidung oder anderen textilen Flächengebilden, wie Handtüchern oder Bettwäsche, sondern auch bei der Reinigung im Haushalt selbst, beispielsweise von harten Oberflächen wie Böden, Bädern oder auch Geschirr.The problem of microorganisms adhering, however, does not only exist on clothing or other textile fabrics, such as towels or bed linen, but also when cleaning in the household itself, for example hard surfaces such as floors, bathrooms or dishes.
Durch das vorherrschende Waschverhalten können mit Viren, Bakterien oder anderen Mikroorganismen verunreinigte Textilien oder Oberflächen nicht im erforderlichen Maße keimfrei gemacht werden, so dass unter Umständen eine Infektion oder Reinfektion erfolgen kann.Due to the prevailing washing behavior, textiles or surfaces contaminated with viruses, bacteria or other microorganisms cannot be made aseptic to the required extent, so that an infection or reinfection may occur.
Antimikrobiell wirksame Verbindungen und Zusammensetzungen sowie deren Einsatz in Waschmitteln sind im Stand der Technik bekannt. So offenbart beispielsweise
In
Eine Aufgabe der vorliegenden Erfindung ist daher die Bereitstellung eines antimikrobiell wirksamen Wasch- oder Reinigungsmittels mit wenigstens einer quaternären Ammoniumverbindung, in welcher die antimikrobielle Wirksamkeit gegenüber bekannten Formulierungen verbessert ist.One object of the present invention is therefore to provide an antimicrobially active washing or cleaning agent with at least one quaternary ammonium compound in which the antimicrobial effectiveness is improved compared to known formulations.
Überraschenderweise hat sich gezeigt, dass durch Glutaminsäure-N,N-diessigsäure oder deren Salze eine verbesserte antimikrobielle Wirkung der quaternären Ammoniumverbindungen erreicht werden kann, obwohl die Glutaminsäure-N,N-diessigsäure beziehungsweise deren Salze selbst nicht antimikrobiell wirksam sind. Überraschenderweise hat sich hier ein synergistischer Effekt zwischen den quaternären Ammoniumverbindungen und Glutaminsäure-N,N-diessigsäure beziehungsweise deren Salze gezeigt.Surprisingly, it has been shown that glutamic acid-N, N-diacetic acid or its salts can achieve an improved antimicrobial effect of the quaternary ammonium compounds, although the glutamic acid-N, N-diacetic acid or its salts themselves are not antimicrobial. Surprisingly, a synergistic effect has been shown here between the quaternary ammonium compounds and glutamic acid-N, N-diacetic acid or its salts.
Unter Verwendung eines erfindungsgemäßen Wasch- oder Reinigungsmittels kann somit auch bei niedrigen Waschtemperaturen sowie mit Flüssigwaschmitteln ein Hygieneeffekt erzielt werden, der vergleichbar ist mit der hygienischen Leistung von bleichehaltigen Pulverwaschmitteln bei höheren Temperaturen von 60 °C oder mehr. Für Reinigungsmittel von harten Oberflächen kann auf diese Weise ebenfalls eine vorherrschende Wirksamkeitslücke gegen Pseudomonadae oder andere Mikroorganismen geschlossen werden.Using a washing or cleaning agent according to the invention, a hygiene effect can thus be achieved even at low washing temperatures and with liquid detergents, which is comparable to the hygienic performance of bleach-containing powder detergents at higher temperatures of 60 ° C. or more. For cleaning agents for hard surfaces, a predominant effectiveness gap against Pseudomonadae or other microorganisms can also be closed in this way.

So ist es für den Fachmann offensichtlich, dass in Formel (la) beziehungsweise (IIa) A nicht für ein Element der 15. oder 16. Gruppe des (PSE) steht, ebenso wie in Formel (Ib) beziehungsweise (IIb) Elemente der 16. Gruppe ausgeschlossen sind. Soweit A eine offene Valenz aufweist, ist an diese ein Wasserstoffatom gebunden.A is preferably selected from a substituted or unsubstituted alkyl or aryl radical having 2 to 14 carbon atoms, or an element of group 14, 15 or 16 of the Periodic Table (PSE). These are of course restricted according to the valence of the atoms.

In verschiedenen Ausführungsformen werden die Substituenten ausgewählt aus =O, =S, -OH, -SH, -NH2 -NO2, -CN, -F, -Cl, -Br, C1-10 Alkyl, C2-10 Alkenyl, C2-10 Alkinyl, C3-8 Cycloalkyl, C6-14 Aryl, einem 5 bis 10 gliedrigen Heteroarylring in dem 1 bis 4 Ringatome unabhängig Stickstoff, Sauerstoff oder Schwefel sind, und einem 5 bis 10 gliedrigen heteroalicyclischen Ring in dem 1 bis 3 Ringatome unabhängig Stickstoff, Sauerstoff oder Schwefel sind.The alkyl radical and / or the aryl radical can be substituted. “Substituted”, as used herein in connection with the substituents and radicals according to the invention, means that one or more H atoms and / or one or more C atoms in the corresponding group have been replaced by other functional groups, these being selected in particular from those containing one or more heteroatoms. In various embodiments, the substituents are selected from = O, = S, -OH, -SH, -NH 2 -NO 2 , -CN, -F, -Cl, -Br, C 1-10 alkyl, C 2-10 alkenyl , C 2-10 alkynyl, C3-8 cycloalkyl, C 6-14 aryl, a 5 to 10 membered heteroaryl ring in which 1 to 4 ring atoms are independently nitrogen, oxygen or sulfur, and a 5 to 10 membered heteroalicyclic ring in the 1 to 3 ring atoms are independently nitrogen, oxygen or sulfur.
In der allgemeinen Strukturformel (Ib steht A bevorzugt für ein Element der 15. Gruppe des PSE. Besonders bevorzugt ist es Stickstoff (N) oder Phosphor (P). Besonders bevorzugt steht A für N.In the general structural formula (Ib, A preferably stands for an element of group 15 of the PSE. It is particularly preferably nitrogen (N) or phosphorus (P). A particularly preferably stands for N.
In dieser bevorzugten Ausführungsform stehen m, n, o und p jeweils unabhängig voneinander für 0, 1, 2, 3, oder 4, insbesondere für 0, 1 oder 2. Erfindungsgemäß ist die Tetracarbonsäure Glutaminsäure-N,N-diessigsäure, in welcher n = 0, m und o = 1 und p = 2 ist und A für N steht.In this preferred embodiment, m, n, o and p each independently represent 0, 1, 2, 3 or 4, in particular 0, 1 or 2. According to the invention, the tetracarboxylic acid is glutamic acid-N, N-diacetic acid, in which n = 0, m and o = 1 and p = 2 and A is N.
Das Wasch- oder Reinigungsmittel umfasst vorzugsweise wenigstens 0,05 Gew.-% oder mehr, bezogen auf das Gesamtgewicht des Wasch- oder Reinigungsmittels, der wenigstens einen Tetracarbonsäure oder deren Salzen. Es hat sich gezeigt, dass dieser Anteil notwendig ist, um eine verstärkende Wirkung der QAV zu ermöglichen. Bevorzugt weist das Wasch- oder Reinigungsmittel die Tetracarbonsäuren in einem Anteil von 0,05 Gew.-% bis 5 Gew.-%, insbesondere von 0,05 Gew.-% bis 3 Gew.-%, bevorzugt von 0,1 Gew.-% bis 1 Gew.-% auf. Darüber hinausgehende Mengen führen nicht zu einer weiteren Verstärkung des antimikrobiellen Effektes der QAV, so dass ein "Mehr" nicht zu einer wesentlichen Leistungssteigerung führt.The washing or cleaning agent preferably comprises at least 0.05% by weight or more, based on the total weight of the washing or cleaning agent, of the at least one tetracarboxylic acid or its salts. It has been shown that this proportion is necessary to enable the QAV to have a reinforcing effect. The detergent or cleaning agent preferably contains the tetracarboxylic acids in a proportion of 0.05% by weight to 5% by weight, in particular 0.05% by weight to 3% by weight, preferably 0.1% by weight. -% to 1% by weight. Amounts in excess of this do not lead to a further strengthening of the antimicrobial effect of the QAV, so that "more" does not lead to a significant increase in performance.
Ohne an diese Theorie gebunden zu sein, wird davon ausgegangen, dass die Glutaminsäure-N,N-diessigsäure aufgrund der Eigenschaften als Chelatbildner den Zugang zur Zellmembran der Mikroben ermöglicht, so dass die QAV eine verbesserte Angriffswirkung aufweisen. Überraschenderweise hat sich gezeigt, dass die Tetracarbonsäuren sowohl bei sauren als auch bei neutralen sowie basischen pH-Werten funktionsfähig sind. Das erfindungsgemäße Wasch- oder Reinigungsmittel kann somit einen pH-Wert von 7, >7 oder <7 aufweisen.Without being bound by this theory, it is assumed that the glutamic acid-N, N-diacetic acid enables access to the cell membrane of the microbes due to its properties as a chelating agent, so that the QAV have an improved attack effect. Surprisingly, it has been shown that the tetracarboxylic acids are functional both at acidic and at neutral and basic pH values. The washing or cleaning agent according to the invention can thus have a pH of 7,> 7 or <7.

The alkylation of tertiary amines with one long alkyl radical and two methyl groups is particularly easy; the quaternization of tertiary amines with two long radicals and one methyl group can also be carried out with the aid of methyl chloride under mild conditions. Amines which have three long alkyl radicals or hydroxy-substituted alkyl radicals are not very reactive and are preferably quaternized with dimethyl sulfate.

Geeignete Tenside sind im Stand der Technik hinlänglich beschrieben.The washing or cleaning agent according to the invention can have a surfactant or mixtures of 2, 3 or more surfactants. If the washing or cleaning agent comprises more than one surfactant, it can be, for example, 2, 3 or more different amphoteric (zwitterionic) surfactants. However, it is also possible to use 1, 2, 3 or more nonionic surfactants, for example combined with 1, 2, 3 or more cationic surfactants. Suitable surfactants are adequately described in the prior art.
Bevorzugt umfasst das Wasch- oder Reinigungsmittel nichtionische und/oder kationische und/oder zwitterionische Tenside.

Also suitable are a mixture of a (more) branched ethoxylated fatty alcohol and an unbranched ethoxylated fatty alcohol, such as, for example, a mixture of an e 16-18 fatty alcohol with 7 EO and 2-propylheptanol with 7 EO. The washing or cleaning agent particularly preferably contains a C 12-18 fatty alcohol with 7 EO as the alkoxylated fatty alcohol.
In einer alternativen Ausführungsform ist das flüssige Wasch- oder Reinigungsmittel frei von alkoxylierten Fettalkoholen, da diese zu einer leichten Trübung des flüssigen Wasch- oder Reinigungsmittels und dadurch für einige Anwender zu einem ästhetisch weniger ansprechenden Produkt führen.In an alternative embodiment, the liquid washing or cleaning agent is free from alkoxylated fatty alcohols, since these lead to a slight clouding of the liquid washing or cleaning agent and thus to a less aesthetically pleasing product for some users.
