Definitions
- the invention relates to a storage-stable, aqueous, antimicrobial effect developing composition on the Basis of a peracid, which, regardless of the hardness of the Dilution water, has a high foaming power.
- liquid percarboxylic acid compositions have long been known.
- peracids they are known to contain anionic and nonionic surfactants, H 2 O 2 , stabilizers for the peroxide compounds.
- H 2 O 2 anionic and nonionic surfactants
- stabilizers for the peroxide compounds.
- H 2 O 2 nonionic surfactants
- 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.
- compositions according to DE-OS 26 16 049 when used in water certain hardness a greatly reduced foaming power show as a similar system, but containing demineralized water as dilution water.
- the invention is based on the object a storage-stable composition of the type mentioned to provide the ability to generate one of the water hardness has foam that cannot be influenced.
- 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.
- composition of the invention has one Minimum content of 0.5% by weight of a polyalkylene glycol or its ether on and a maximum content that the Solubility value of this agent in the used Composition corresponds.
- 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 with a perforated plate attached to a handle for 30 seconds and the behavior of solutions in distilled or hard water at the above-mentioned 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.
- the present composition advantageously contains Stabilizers for the peroxy compounds as well as anionic and non-ionic surfactants.
- Stabilizers for the peroxy compounds as well as anionic and non-ionic surfactants.
- As stabilizers of the above Kind are preferred nitrogen-containing carboxylic acids and their derivatives and organic phosphonates used.
- Suitable phosphonic acids are, for example, 1 hydroxyethane 1,1-diphosphonic acid.
- 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 composition basically represents a solution consisting of lower aliphatic monocarboxylic acids which essentially contains H 2 O 2 , acetic acid and water in addition to the peracid, the contents of these components corresponding to the required equilibrium ratios.
- 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.
- composition formed according to the invention is sufficiently resistant to a good microbicidal and virucidal To have an impact. It also has through the share in Polyalkylene glycol or its ether without the benefit
- a concentrate was prepared, which was a 4% Solution of the respective additive was added.
- 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.
- V s in% V 2 V 1 ⁇ 100
- 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.

Description
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.
Die Unteransprüche zeigen besondere Ausführungsformen der Erfindung.
Zweckmäßigerweise besitzen solche Polyalkylenglykole und Polyalkylenglykolether ein mittleres Molekulargewicht von 400 bis 1500 g/mol.
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.
Bevorzugt sind die vorliegenden lagerstabilen Zusammensetzungen gekennzeichnet durch einen Gehalt von 0,15 - 15 Gew.-% an Persäure, bei einem Gehalt an aktivem Sauerstoff von 2,5 - 35 Gew-%.
Der Gehalt an Stabilisierungsmitteln für die Peroxyverbindungen wird dem entsprechenden Gehalt der Peroxyverbindungen angepaßt, so daß eine maximale Lagerbeständigkeit resultiert.
