Definitions

• 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.
• 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 of certain hardness, show a greatly reduced foaming power as a similar system, but containing demineralized water as the dilution water.
• 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.
• 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 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.
• 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.
• 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.
• 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 stable to have a good microbicidal and virucidal action. Furthermore, it has the advantage of the proportion of polyalkylene glycol or its ether without
• a concentrate was prepared, to which a 4% solution of the respective additive was added.
• 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.
• 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 2nd 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.
• compositions containing the additive according to the invention were tested for their storage stability at various time intervals. The following values resulted:
