Die Erfindung betrifft ein tensidhaltiges wässriges antimikrobiell wirksames Reinigungsmittel für harte Oberflächen, das mindestens ein Acrylcopolymer, eine quaternäre Ammoniumverbindung und Ameisensäure umfasst. Das Mittel eignet sich zur Reinigung und/oder antimikrobiellen Behandlung harter Oberflächen, insbesondere in Feuchträumen wie Badezimmern. The invention relates to a surfactant-containing aqueous antimicrobial hard surface cleaner comprising at least one acrylic copolymer, a quaternary ammonium compound and formic acid. The composition is useful in the cleaning and / or antimicrobial treatment of hard surfaces, especially in wet rooms such as bathrooms.
Vor allem in feuchten bzw. feuchtwarmen Räumen, in denen Bakterien und Schimmelpilze ideale Wachstumsbedingungen vorfinden, ist neben der einfachen Reinigung auch die antimikrobielle Behandlung harter Oberflächen sinnvoll und wünschenswert. Insbesondere Schimmelpilze, allen voran Aspergillus niger, haben sich als hartnäckig erwiesen und sind dabei als Especially in humid or warm, humid rooms, where bacteria and molds find ideal growth conditions, not only the simple cleaning but also the antimicrobial treatment of hard surfaces is useful and desirable. In particular, mold fungi, especially Aspergillus niger, have proven to be persistent and are considered as
gesundheitsschädlich bekannt. Harmful known.
Auch eine Verbesserung der Reinigungsleistung und/oder eine Verringerung der Also, an improvement in cleaning performance and / or a reduction in the
Wiederanschmutzungsneigung, insbesondere gegenüber Kalkseifen, wäre wünschenswert, um den Keimen ihren Nährboden zu rauben und so zu einer geringeren Verkeimung der Oberflächen zu gelangen. Resistant to soiling, especially against lime soils, would be desirable in order to rob the germs of their breeding ground and thus to a lower bacterial contamination of the surfaces.
Es hat sich nun gezeigt, dass ein tensidhaltiges wässriges Mittel, welches mindestens ein Acrylcopolymer, eine quaternäre Ammoniumverbindung und Ameisensäure enthält, eine hohe antimikrobielle Wirksamkeit gegenüber Keimen wie Staphylococcus aureus, Enterococcus hirae, Pseudomonas aeruginosa, Escherichia coli, Candida albicans und Aspergillus niger aufweist und daneben noch eine hervorragende Reinigungsleistung zeigt.

Komplexbildner complexing
Komplexbildner (INCI Chelating Agents), auch Sequestriermittel genannt, sind Inhaltsstoffe, die Metallionen zu komplexieren und inaktivieren vermögen, um ihre nachteiligen Wirkungen auf die Stabilität oder das Aussehen der Mittel, beispielsweise Trübungen, zu verhindern. Einerseits ist es dabei wichtig, die mit zahlreichen Inhaltsstoffen inkompatiblen Calcium- und Magnesiumionen der Wasserhärte zu komplexieren. Die Komplexierung der Ionen von Schwermetallen wie Eisen oder Kupfer verzögert andererseits die oxidative Zersetzung der fertigen Mittel. Zudem unterstützen die Komplexbildner die Reinigungswirkung. In einer bevorzugten Ausführungsform enthält das erfindungsgemäße Mittel daher einen oder mehrere Komplexbildner. INCI chelating agents, also called sequestrants, are ingredients that are capable of complexing and inactivating metal ions to prevent their detrimental effects on the stability or appearance of the agents, such as clouding. On the one hand, it is important to use calcium and magnesium ions, which are incompatible with numerous ingredients Complex water hardness.

Die Begriffe Desinfektion, Sanitation, antimikrobielle Wirkung und antimikrobieller Wirkstoff haben im Rahmen der erfindungsgemäßen Lehre die fachübliche Bedeutung, die beispielsweise von K. H. Wallhäußer in "Praxis der Sterilisation, Desinfektion - Konservierung : Keimidentifizierung - Betriebshygiene" (5. Aufl. - Stuttgart ; New York : Thieme, 1995) wiedergegeben wird. Während Desinfektion im engeren Sinne der medizinischen Praxis die Abtötung von - theoretisch allen - Infektionskeimen bedeutet, ist unter Sanitation die möglichst weitgehende Eliminierung aller - auch der für den Menschen normalerweise unschädlichen saprophytischen - Keime zu verstehen. The terms disinfection, sanitation, antimicrobial action and antimicrobial agent have the usual meaning in the context of the teaching of the invention, for example, by KH Wallhäußer in "Practice of sterilization, disinfection - Conservation: germ identification - company hygiene" (5th ed. - Stuttgart, New York : Thieme, 1995). While disinfection in the narrower sense of the medical practice means the killing of - in theory all - infectious germs, sanitation is to be understood as the greatest possible elimination of all - including the saprophytic - normally harmless to humans saprophytic - germs.
Hierbei ist das Ausmaß der Desinfektion bzw. Sanitation von der antimikrobiellen Wirkung des angewendeten Mittels abhängig, die mit abnehmendem Gehalt an antimikrobiellem Wirkstoff bzw. zunehmender Verdünnung des Mittels zur Anwendung abnimmt.
