Die antimikrobielle Wirksamkeit flüssiger Percarbonsäure - Zusammensetzungen ist seit langem bekannt. Sie können bekannterweise neben Persäuren anionische und nichtionische Tenside, H2O2,Stabilisatoren für die Peroxydverbindungen, enthalten.
Obwohl die bekannten Mittel den Normen für antimikrobielle Aktivität genügen oder sie übertreffen, leiden viele der bekannten Mittel an dem Mangel, daß sie Schaum mit schwankender Beständigkeit erzeugen, je nach Art des eingesetzten Verdünnungswassers.The antimicrobial effectiveness of liquid percarboxylic acid compositions has long been known. In addition to peracids, they are known to contain anionic and nonionic surfactants, H 2 O 2 , stabilizers for the peroxide compounds.

Die Messungen werden im allgemeinen bei Flüssigkeitstemperaturen von (25±2) C vorgenommen. Der Schaum wird durch 30 Sekunden langes Schlagen der Lösungen in einem Standzylinder mit einer an einem Stiel befestigten, gelochten Platte erzeugt und das Verhalten von Lösungen in destilliertem bzw. hartem Wasser bei den o.g. Temperaturen geprüft. Als Bezugslösung wird eine Lösung von Natriumdodecylsulfat in destilliertem Wasser verwendet. Das Schaumvolumen der Probenlösungen wird 30 Sekunden nach Beendigung des Schlagens gemessen.The foaming power at different water hardness is checked under the conditions of DIN 53902, part 1.
Under these conditions, the foam produced with the composition according to the invention, compared to the comparison solution, is an increase between 100% and 140%.

Das folgende Beispiel erläutert die Erfindung.The following example illustrates the invention.

Es wurde ein Konzentrat hergestellt, welchem eine 4%-ige Lösung des jeweiligen Zusatzes zugefügt wurde.A concentrate was prepared, which was a 4% Solution of the respective additive was added.

Als Bezugslösung für die Messreihe wurde eine Lösung von Na-dodecylsulfat in destilliertem Wasser nach DIN 53902, Teil 1, verwendet.As a reference solution for the series of measurements, a solution from Sodium dodecyl sulfate in distilled water according to DIN 53902, Part 1 used.

Zur Bestimmung des Schaumvolumens kam eine 2%-ige Lösung des Konzentrats der nachstehenden Zusammensetzung zur Anwendung: Komponenten Gew.-% Essigsäure 11.0 C10C13-Alkylbenzolsulfonsäure 3.0 C13-Oxoalkoholethoxylat mit 12 EO ( i-C13H27O(CH2CH2O)xH mit x=12 3.0 Polypropylenglycol, mittlere molare Masse ca. 900 g/mol 4.0 1-Hydroxyethan (1,1 diphosphonsäure) (HEDP) als Stabilisator für Peroxyverbindungen 1.0 Wasserstoffperoxid 6.0 VE-Wasser 70.8 Peressigsäure 1.2 Zur Durchführung der Messungen wurden in einem Meßzylinder 200ml der Bezugslösung und in die übrigen Meßzylinder je 200ml der Probenlösung mit einem nicht erfindungsgemäßen Zusatz bzw. mit einem erfindungsgemäßen Zusatz, ein Polyalkylenglykol mit einer mittleren molaren Masse von 600 bzw. 900 g/mol vorsichtig unter Vermeidung von Schaumentwicklung eingefüllt.A 2% solution of the concentrate of the following composition was used to determine the foam volume: Components % By weight acetic acid 11.0 C 10 C 13 alkylbenzenesulfonic acid 3.0 C 13 oxo alcohol ethoxylate with 12 EO (iC 13 H 27 O (CH 2 CH 2 O) x H with x = 12 3.0 Polypropylene glycol, average molar mass approx. 900 g / mol 4.0 1-hydroxyethane (1,1 diphosphonic acid) (HEDP) as a stabilizer for peroxy compounds 1.0 Hydrogen peroxide 6.0 VE water 70.8 Peracetic acid 1.2 To carry out the measurements, 200 ml of the reference solution and in each of the other measuring cylinders, 200 ml of the sample solution with an additive not according to the invention or with an additive according to the invention, were carefully avoided while avoiding a polyalkylene glycol with an average molar mass of 600 or 900 g / mol filled in by foam development.

Bezugslösung und Probenlösungen wurden vor dem Einfüllen auf die am Thermostaten eingestellte Versuchstemperatur gebracht. Sodann wurden durch manuelles Betätigen mit den Schaumstempeln 30 gleichmäßige Schläge innerhalb von 30 Sekunden ausgeführt.
30 Sekunden nach Beendigung des Schlagens wurden die Schaumvolumen in ml an der Teilung der Meßzylinder abgelesen, wobei die Mengen der in Schaum überführten Flüssigkeit unberücksichtigt blieben.The reference solution and sample solutions were brought to the test temperature set on the thermostat before filling. Then 30 uniform strokes were carried out within 30 seconds by manual actuation with the foam punches.
30 seconds after the end of the beating, the foam volumes in ml were read from the graduation of the measuring cylinders, the quantities of the liquid transferred into the foam being ignored.

Bei diesem von Hand erfolgten Schlagen wurde darauf geachtet, daß die Hubhöhe der Schaumstempel möglichst konstant gehalten und dabei unter Einhaltung des Schlagintervalls vom Maschinenschlagverfahren, d. h. möglichst gleichmäßig geschlagen wurde.This was done by hand made sure that the lifting height of the foam stamp as possible kept constant while maintaining the Strike interval from machine impact method, d. H. was beaten as evenly as possible.

Aus den gefundenen Werten wurden das Schaumvolumen Vs in %, bezogen auf das Schaumvolumen der Vergleichslösung, nach folgender Gleichung errechnet: Vs = V2 V1 · 100 The foam volume V s in%, based on the foam volume of the comparison solution, was calculated from the values found using the following equation: V s = V 2 V 1 · 100

Hierin bedeuten:

V1
Schaumvolumen der Vergleichslösung gemäß DIN 53902, T 1, in ml
V2
Schaumvolumen der Probenlösung in ml, wobei Lösungen mit Zusätzen des Standes der Technik bzw. mit erfindungsgemäßen Zusätzen im Verhältnis zur Standard-Vergleichslösung gestellt wurden.
Here mean:
V 1
Foam volume of the comparison solution according to DIN 53902, T 1, in ml
V 2
Foam volume of the sample solution in ml, solutions with additives of the prior art or with additives according to the invention being placed in relation to the standard comparison solution.

Die erhaltenen Werte wurden in der nachstehenden Tabelle zusammengefaßt.

Daraus ist erkennbar, daß der Schaumstandard von 133 annähernd nur wieder bei Zusammensetzungen enthaltend Polyalkylenglykol erreicht wird.From this it can be seen that the foam standard of 133 almost only again with compositions containing Polyalkylene glycol is achieved.

Die Komplexierung der Wasserhärte mittels Hexametaphosphat zeigt einen ähnlich guten Effekt.
Hexametaphosphat ist in Peressigsäure aber nicht lagerstabil, sowie auch viele andere, hier nicht beschriebene Zusatzmittel die Lagerstabilität der resultierenden Gesamtzusammensetzung empfindlich reduzieren.The complexation of the water hardness with hexametaphosphate shows a similarly good effect.
However, hexametaphosphate is not stable in storage in peracetic acid, and many other additives not described here also significantly reduce the storage stability of the resulting overall composition.

Zusammensetzungen enthaltend das erfindungsgemäße Zusatzmittel, wurden in verschiedenen Zeitabständen auf ihre Lagerstabilität geprüft. Es ergaben sich folgende Werte:
