Description
Gegenstand der Erfindung sind antimikrobielle Mittel mit potenzierter Wirkung, die als wesentliche Bestandteile eine synergistische Kombination eines Alkyl- oder Cycloalkyldiacetats mit einem Komplexbildner enthalten. The invention relates to antimicrobial agents with potentiated Effect that is a synergistic combination of an essential component Contain alkyl or cycloalkyl diacetate with a complexing agent.
Es ist bereits bekannt, daß Alkyldiacetate antimikrobielle Verbindungen mit relativ guter Wirksamkeit darstellen. Oftmals ist es jedoch, wie bei der Verwendung aller antimikrobiellen Substanzen, wünschenswert, unter Einsatz möglichst geringer Konzentrationen gute antimikrobielle Wirkungen zu erzielen. It is already known that alkyl diacetates are antimicrobial compounds represent with relatively good effectiveness. Often, however, it is just like using of all antimicrobial substances, desirable, using as little as possible Concentrations to achieve good antimicrobial effects.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, antimikrobielle Mittel auf Basis von Alkyl-bzw. Cycloalkyldiacetaten aufzufinden, deren antimikrobieller Effekt erheblich über denjenigen der ihnen zugrunde liegenden substituierten Diacetate hinausgeht. Diese Aufgabe wird dadurch gelöst, daß man ein antimikrobielles Mittel verwendet, welches als wesentliche wirksame Bestandteile eine synergistisch wirkende Kombination eines Diacetats der allgemeinen Formel in der X Wasserstoff oder Chlor bedeutet, A einen gesättigten oder ungesättigten, gerad- oder verzweigtkettigen aliphatischen Kohlenwasserstoffrest mit 1 bis 8 Kohlenstoffatomen oder einen cycloaliphatischen Kohlenwasserstoffrest darstellen kann, R1, R2, R3 und R4 für Wasserstoff oder einen aliphatischen Kohlenwasserstoffrest mit 1 bis 3 Kohlenstoffatomen stehen, wobei die beiden Estergruppen tragenden Kohlenstoffatome zusammen mit A und R1 bis R4 einen cycloaliphatischen Ring bilden können, mit einem Komplexbildner, der im Hampshire-Test nach der Calciumcarbonatmethode ein größeres Calciumcarbonat-Bindevermögen als 230 mg pro 1 g Komplexbildner besitzt, enthält.The present invention is therefore based on the object of providing antimicrobial agents based on alkyl or.

Durch die nachfolgenden Beispiele wird der Gegenstand vorliegender Erfindung näher erläutert. The subject matter will become clearer through the following examples Invention explained in more detail.
Die Hemmkonzentrationen der zu untersuchenden Alkyl- bzw. Cycloalkyldiacetate sowie der Kombination dieser Produkte mit den verschiedenen Komplexbildnern wurden mit Hilfe des sogenannten Plattentestes ermittelt. Dieser Test stellt eine abgewandelte Ausführungsform des in den Richtlinien für die Prüfung chemischer Desinfektionsmittel der Deutschen Gesellschaft für Hydiene und Mikrobiologie unter den Methoden zur Vorprüfung solcher Mittel beschriebenen Verdünnungstestes zur Bestimmung der mikrobiostatischen Wirkung dar und läßt sich mit Vorteil bei verschiedenen Prüfungen an Stelle der dort angegebenen Verwendung flüssiger Nährböden einsetzen. Der Vorteil fester Nährböden liegt insbesondere bei Prüfungen der Wirksamkeit von Substanzen gegenüber Pilzen klar auf der Hand. The inhibitory concentrations of the alkyl or cycloalkyl diacetates to be examined as well as the combination of these products with the various complexing agents determined with the help of the so-called plate test. This test is a modified one Embodiment of the guidelines for the testing of chemical disinfectants of the German Society for Hydiene and Microbiology among the methods for Preliminary testing of such agents described dilution test to determine the microbiostatic Effect and can be used with advantage in various tests instead of Use liquid culture media specified there. The advantage of solid culture media lies particularly in tests of the effectiveness of substances against fungi obvious.
Die gewünschten Prüfkonzentrationen wurden durch Mischen von abgemessenen Mengen der Substanzlösungen geeigneter Konzentrationen mit abgemessenen Mengen verflüssigter Bouillon- bzw. Bier-Würze-Agars in sterilen Petrischalen hergestellt. Die einpipettierten Mengen der Substanzlösungen betrugen 0,1 bis maximal 1 ml, das Gesamtvolumen in den Petrischalen nach dem Mischen mit dem Nährboden 10 ml. Nach dem Erstarren des Nährbodens wurde die Oberfläche mit der Testkeimsuspension in Bouillon bzw. Würze beimpft, welche pro Milliliter etwa 108 Keime enthielt. Die Bebrütung erfolgte bei 37 bzw. 30°C im Brutschrank und dauerte im Falle der Verwendung von Bakterien bzw. Candida albicans 8 Tage, im Falle der Verwendung von Epidermophyton Kaufmann-Wolf 21 Tage. Die Bebrütungsdauer von 21 Tagen bei Epidermophyton Kaufmann-Wolf wurde in Anlehnung an die vorstehend erwähnten Richtlinien gewählt, weil bei der Bewertung von Desinfektionsmitteln gegen Hautpilze ein Mittel dann als geeignet angesehen wird, wenn das Wachstum der Pilze nach bestimmter Einwirkungsdauer des Mittels um mindestens 21 Tage verzögert wird. Anschließend wurde festgestellt, welche in den Nährböden eingearbeitete Substanzkonzentration das Wachstum der Testkeime gerade noch völlig unterbinden konnte. The desired test concentrations were measured by mixing Quantities of the substance solutions of suitable concentrations with measured quantities of liquefied ones Broth or beer-wort agars produced in sterile Petri dishes. The pipetted amounts of the substance solutions were 0.1 to a maximum of 1 ml, the total volume in the Petri dishes after mixing with the nutrient medium 10 ml. After solidification of the nutrient medium became inoculates the surface with the test germ suspension in broth or wort, which contained about 108 germs per milliliter. Incubation took place at 37 and 30 ° C, respectively in the incubator and lasted in the case of the use of bacteria or Candida albicans 8 days, in the case of using Epidermophyton Kaufmann-Wolf 21 days. The incubation period of 21 days for Epidermophyton Kaufmann-Wolf was based on the above mentioned guidelines because when evaluating disinfectants against Skin fungi a remedy is then considered suitable when the growth of the mushrooms is delayed by at least 21 days after a certain period of exposure to the agent. It was then determined which substance concentration incorporated in the nutrient media was just able to completely prevent the growth of the test germs.
Dieser so ermittelte Wert wurde als Hemmkonzentration bezeichnet. Die Untersuchungen wurden in folgenden Konzentrationsintervallen durchgeführt: 20000, 10 000, 5000, 2500, 1000, 750, 500, 250, 100, 50, 25, 10, 5, 2,5, 1, 0,5, 0,25 und 0,1 ppm.This value determined in this way was referred to as the inhibitory concentration. The tests were carried out at the following concentration intervals: 20,000, 10,000, 5000, 2500, 1000, 750, 500, 250, 100, 50, 25, 10, 5, 2.5, 1, 0.5, 0.25 and 0.1 ppm.
Die verwendeten Komplexbildner zeigten in den eingesetzten Konzentrationen allein keinen hemmenden Einfluß auf das Wachstum der Mikroorganismen. The complexing agents used showed in the concentrations used alone no inhibiting influence on the growth of the microorganisms.
