Abstract
Description
Die Erfindung betrifft eine lagerstabile, wäßrige, antimikrobielle Wirkung entwickelnde Zusammensetzung auf der Basis einer Persäure, welche, unabhängig von der Härte des Verdünnungswassers, ein hohes Schaumvermögen aufweist.The invention relates to a storage-stable, aqueous, antimicrobial effect-developing composition based on a peracid, which, regardless of the hardness of the dilution water, has a high foaming power.
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.
Although the known agents meet or exceed the standards for antimicrobial activity, many of the known agents suffer from the deficiency that they produce foam with varying resistance depending on the type of dilution water used.
So wurde beispielsweise festgestellt, daß Zusammensetzungen gemäß DE-OS 26 16 049, bei ihrer Anwendung im Wasser bestimmter Härte ein stark vermindertes Schaumvermögen zeigen als ein gleichartiges System, enthaltend jedoch entmineralisiertes Wasser als Verdünnungswasser.For example, it has been found that compositions according to DE-OS 26 16 049, when used in water of certain hardness, show a greatly reduced foaming power as a similar system, but containing demineralized water as the dilution water.
Wässer, die hohe Härte aufweisen, kann man bekannterweise mit Substanzen aufbereiten, die in unterstöchiometrischen Mengen die Ausfällung der Härtebildner erheblich verzögern, wie beispielsweise Polyphosphate; die verwendeten Polyphosphate sind jedoch in Gegenwart von Persäuren nicht lagerstabil.It is known that water which has a high hardness can be treated with substances which, in substoichiometric amounts, considerably delay the precipitation of the hardness formers, for example polyphosphates; however, the polyphosphates used are not stable in storage in the presence of peracids.
In diesem Sinne liegt der Erfindung die Aufgabe zugrunde, eine lagerstabile Zusammensetzung der genannten Gattung bereitzustellen, welche das Vermögen zur Erzeugung eines von der Wasserhärte nicht beeinflußbaren Schaumes aufweist.In this sense, the invention has for its object to provide a storage-stable composition of the type mentioned, which has the ability to produce a foam that cannot be influenced by the water hardness.
Diese Aufgabe wird mit den erfindungsgemäßen Merkmalen des Anspruchs 1 gelöst.
Die Unteransprüche zeigen besondere Ausführungsformen der Erfindung.This object is achieved with the features of claim 1 according to the invention.
The subclaims show particular embodiments of the invention.
Es wurde überraschenderweise gefunden, daß die wasserhärteabhängige Schaumbildung einer an sich bekannte Komponenten enthaltenden Zusammensetzung durch Zugabe eines Polyalkylenglykols oder seines Ethers vermieden werden kann.It has surprisingly been found that the water hardness-dependent foam formation of a composition containing components known per se can be avoided by adding a polyalkylene glycol or its ether.
Das Polyalkylenglykol oder sein Ether wird insbsondere aus der Gruppe geradkettiger Polyalkylenglykole, wie Polyalkylenglykolether oder eines ihrer Mono- oder Diniedrigalkyl- oder phenylethers, gewählt.
Zweckmäßigerweise besitzen solche Polyalkylenglykole und Polyalkylenglykolether ein mittleres Molekulargewicht von 400 bis 1500 g/mol.The polyalkylene glycol or its ether is selected in particular from the group of straight-chain polyalkylene glycols, such as polyalkylene glycol ether or one of its mono- or di-lower alkyl or phenyl ether.
Such polyalkylene glycols and polyalkylene glycol ethers advantageously have an average molecular weight of 400 to 1500 g / mol.
Die erfindungsgemäße Zusammensetzung weist einen Mindestgehalt von 0,5 Gew.-% an einem Polyalkylenglykol oder seinem Ether auf und einen maximalen Gehalt, der dem Löslichkeitswert dieses Mittels in der eingesetzten Zusammensetzung entspricht.The composition according to the invention has a minimum content of 0.5% by weight of a polyalkylene glycol or its ether and a maximum content which corresponds to the solubility value of this agent in the composition used.
Das Schaumvermögen bei verschiedenen Wasserhärten wird unter den Bedingungen der DIN 53902, Teil 1 geprüft.
Unter diesen Bedingungen beträgt der mit der erfindungsgemäßen Zusammensetzung erzeugte Schaum, gegenüber der Vergleichslösung, eine Zunahme zwischen 100 % und 140 %. 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%. The measurements are generally carried out at liquid temperatures of (25 ± 2) C. The foam is generated by beating the solutions in a standing cylinder for 30 seconds with a perforated plate attached to a handle and the behavior of solutions in distilled or hard water at the above temperatures is tested. A solution of sodium dodecyl sulfate in distilled water is used as the reference solution. The foam volume of the sample solutions is measured 30 seconds after the beating has ended.
Die vorliegende Zusammensetzung enthält zweckmäßigerweise Stabilisatoren für die Peroxyverbindungen sowie anionische und nicht-ionische Tenside. Als Stabilisatoren der genannten Art werden bevorzugt Stickstoff-haltige Carbonsäuren und ihre Derivate sowie organische Phosphonate eingesetzt.

Geeignete Phosphonsäuren sind beispielsweise 1 Hydroxyethan 1,1-diphosphonsäure.The present composition expediently contains stabilizers for the peroxy compounds and anionic and nonionic surfactants. Nitrogen-containing carboxylic acids and their derivatives and organic phosphonates are preferably used as stabilizers of the type mentioned. Carboxylic acids with a nitrogen-containing heterocycle, such as dipicolinic acid, have been found to be particularly suitable. Suitable phosphonic acids are, for example, 1 hydroxyethane 1,1-diphosphonic acid.
Als waschaktive Substanzen können anionaktive Tenside, wie Alkylbenzolsulfonate und Laurylsulfate sowie nichtionische Tenside des Typs i-C13H27O(CH2-CH2O)xH, verwendet werden.Anionic surfactants such as alkylbenzenesulfonates and lauryl sulfates and nonionic surfactants of the iC 13 H 27 O (CH 2 -CH 2 O) × H type can be used as washing-active substances.

The present storage-stable compositions are preferably characterized by a content of 0.15-15% by weight of peracid and a content of active oxygen of 2.5-35% by weight.
The content of stabilizing agents for the peroxy compounds is adjusted to the corresponding content of the peroxy compounds, so that maximum storage stability results.
Die erfindungsgemäß gebildete Zusammensetzung ist ausreichend beständig, um eine gute mikrobizide und viruzide Wirkung zu entfalten. Ferner hat sie durch den Anteil an Polyalkylenglykol oder seinem Ether den Vorteil, ohneThe composition formed according to the invention is sufficiently stable to have a good microbicidal and virucidal action. Furthermore, it has the advantage of the proportion of polyalkylene glycol or its ether without
Rücksicht auf die Wasserhärte, einen beständigen Schaum zu erzeugen. Diese Tatsache führt, bei der Anwendung des erfindungsgemäßen Zusatzmittels in einem Tensidgemisch zu einer beträchtlichen Verbesserung der Haftwirkung des zu erzeugenden Schaumes, so daß sich die Gesamtzusammensetzung besonders eignet zur bakteriziden und viruziden Behandlung horizontaler und vertikaler Arbeitsflächen, beispielsweise in der Nahrungsmittelindustrie.Consideration of the water hardness to produce a stable foam. This fact leads, when the additive according to the invention is used in a surfactant mixture, to a considerable improvement in the adhesive effect of the foam to be produced, so that the overall composition is particularly suitable for the bactericidal and virucidal treatment of horizontal and vertical work surfaces, for example in the food industry.
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, to which 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.A solution of sodium dodecyl sulfate in distilled water according to DIN 53902, Part 1 was used as the reference solution for the series of measurements.
Zur Bestimmung des Schaumvolumens kam eine 2%-ige Lösung des Konzentrats der nachstehenden Zusammensetzung zur Anwendung:
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.To carry out the measurements, 200 ml of the reference solution and in the other measuring cylinders, each 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.During this hand beating, care was taken to ensure that the lifting height of the foam stamps was kept as constant as possible and, while maintaining the beating interval, by the machine beating method, i. 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:
Hierin bedeuten:
- V1
- Schaumvolumen der Vergleichslösung gemaß 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.
- 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 is almost only achieved again in compositions containing polyalkylene glycol.
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:Compositions containing the additive according to the invention were tested for their storage stability at various time intervals. The following values resulted:
Lagertemperatur T = 20°C
