The invention relates to a liquid disinfectant concentrate.
The biocidal effect of peroxymonosulfuric acid (Caro's acid) and its salts is known.
US Pat. Nos. 38 73 696 and 35 84 119 describe bactericidal and fungicidal compositions containing salts of Caro's acid.
From DE-PS 30 46 769 the use of a mixture of KHSO₅, K₂SO₄ and KHSO₄ (Caroat) together with anionic surfactants as a virucidal agent is known. DE-PS 30 46 769 alkylbenzenesulfonates are mentioned as anionic surfactants.
The known combinations of Caro's acid or Caroat with anionic surfactants are not suitable for the production of liquid disinfectant concentrates. A liquid formulation of 10 parts by weight of caroate, 2.5 parts by weight of sodium alkylbenzenesulfonate and 87.5 parts by weight of water is not homogeneous. For this reason, the disinfectants TPH5720 and TPH574 described in DE-PS 30 46 769 are powdery preparations.
Such powdered disinfectant preparations are now commercially available. They are dissolved in water by the user immediately before use to produce ready-to-use disinfectant solutions. At the application concentration, which is many times lower than the concentration that is to be considered for a liquid disinfectant concentrate, the above-described incompatibility in solution between Caro's acid and the anionic surfactant plays a much smaller role.
The known powdered preparations have a number of disadvantages. The dosage, for example with the help of a measuring cup, is cumbersome. The particularly practical liquid dosing devices cannot be used.
Powdered preparations contain builders or inert constituents due to application requirements. These do not contribute to the actual application, ie disinfection, and can even be disruptive. In many cases they cause residues when used. Inert components also increase the salt load in the wastewater.
Powdered preparations are associated with undesirable dust nuisance both during manufacture and during use. The dust can irritate the mucous membranes, especially the nasal mucous membranes. Therefore, such preparations are not harmless from an occupational medical point of view.
Powdery disinfectant preparations have the further disadvantage that a not inconsiderable time is often required to completely dissolve them in water. Furthermore, the energy input for the production of powdered products is higher than that for the production of liquid products.
The larger the container, the more difficult it is to control thermal processes with solids containing active oxygen; this can lead to uncontrolled decomposition reactions.
Finally, inert substances, which must necessarily be present in powdered preparations, can impair the biocidal effectiveness. With regard to the formulation constituents in question and their quantity, one is restricted in the case of solid preparations.
EP-A-188 025 describes aqueous, thickened cleaning agents which contain peroxymonosulfuric acid or its salts, a strong acid and amine oxides, amines or cationic compounds as thickening surfactants. It is expressly stated that anionic surfactants such as linear alkyl sulfates, alkyl sulfonates and alkylbenzenesulfonates may only be added in small amounts (see EP-A-188 025, column 3, lines 61-65).
To date, there are no liquid, stable disinfectant concentrates based on peroxymonosulfuric acid and / or its salts. This suggests that stability problems and application problems with such liquid formulations have not yet been satisfactorily resolved.
The object of the invention is to provide a storage-stable, liquid disinfectant concentrate which contains peroxymonosulfuric acid and / or its salts as the active oxygen component and has sufficient stability and satisfactory application properties for a commercial product.
The task is solved by a liquid disinfectant concentrate, which<ul id="ul0001" list-style="none"><li>A) as active oxygen component peroxymonosulfuric acid and / or its salts,</li><li>B) predominantly or exclusively as surfactant components<ul id="ul0002" list-style="none"><li>i) primary or secondary alkylsulfonic acids with a linear, branched or cyclic alkyl group which contains 6 to 18 carbon atoms, and / or</li><li>ii) aromatic sulfonic acids of the formula<chemistry id="chem0001" num="0001"><img file="EP0395902A2_D0001.tif" /></chemistry> in which R is a branched or linear alkyl radical having 8 to 18 carbon atoms and m and n are each 0 or 1 with the proviso that the sum m + n is either 1 or 2, and / or</li><li>iii) salts of these sulfonic acids</li></ul></li></ul> as well as water and optionally stabilizers, agents for improving the fungicidal activity and other conventional additives.
The disinfectant concentrate according to the invention is stable both chemically and physically. On the one hand, the active oxygen content in the concentrate is retained over long periods of time. On the other hand, there is no phase separation; there is no precipitation; the components are compatible with one another and together remain clearly in solution over longer periods of time. The surfactants used according to the invention support disinfection and cleaning and reinforce them up to a synergistic increase in activity.
Contrary to the teaching of EP-A-188 025 mentioned above, according to the present invention, surprisingly selected special anionic surfactants are suitable for the preparation of storage-stable, liquid formulations of peroxymonosulfuric acid and its salts.
The vast majority of the commercially available surfactants are not suitable for the production of disinfectant concentrates based on peroxymonosulfuric acid and its salts. Formulations of 10% by weight of caroate, 2.5% by weight of surfactant and 87.5% by weight of water normally show an incompatibility between the constituents, which is evident in phase separation, precipitation, inhomogeneity and destabilization of the active oxygen compound. In view of the large number of unsuitable surfactants, it is surprising that it was possible to find special surfactants for which these incompatibilities do not occur.
It is preferred according to the invention that the active oxygen component A) is contained in the disinfectant concentrate in the form of the mixture of KHSO₅, K₂SO₄ and KHSO₄ referred to as Caroart.
The concentration of the active oxygen component A) in the disinfectant concentrate can be between 1% by weight and the solubility limit. The concentration of active oxygen component A) is preferably 5 to 15% by weight.
The primary or secondary alkyl sulfonic acids used as surfactant component B) i) preferably contain 8 to 16 carbon atoms in the alkyl group.
With regard to the aromatic sulfonic acids used as surfactant component B) ii) according to the formula<chemistry id="chem0002" num="0002"><img file="EP0395902A2_D0002.tif" /></chemistry> it is preferred that the group R is a linear alkyl radical having 10 to 16 carbon atoms.
It is further preferred that in the formula of aromatic sulfonic acid B) ii) the sum is m + n = 2.
It is also preferred that in the formula of aromatic sulfonic acid B) ii) the alkyl radicals R are in the p-position to the ether oxygen bridge.
With regard to the sulfonic acid salts B) iii), it is preferred that they are alkali, alkaline earth metal and / or ammonium salts.
The surfactant component B) is usually contained in the disinfectant concentrate according to the invention in an amount of 0.1 to 200%, preferably 1 to 100% and particularly preferably 5 to 50%, based on the weight of the active oxygen component A).
To ensure good stability of the disinfectant concentrate according to the invention, it is of great importance that the chloride content in the liquid concentrate does not exceed an upper limit. The disinfectant concentrate according to the invention preferably contains less than 0.5% by weight of chloride. On the other hand, very low levels of chloride can have a stabilizing effect. It is therefore particularly preferred that the concentrate according to the invention has a chloride content in the range from 0.005 to 0.5% by weight.
It may be expedient to add stabilizers to the disinfectant concentrate according to the invention. Certain phosphonic acids are suitable for this purpose, in particular 1-hydroxyethane-1,1-diphosphonic acid, morpholinomethane-diphosphonic acid or amino-tris-methylene-phosphonic acid. Pyridinecarboxylic acids are also suitable stabilizers, in particular pyridine-2,6-dicarboxylic acid. Finally, pyrrolidonic acids can also be used for this purpose, especially 2-pyrrolidone-5-carboxylic acid. The stabilizers mentioned can also be used in the form of their salts or in combination with their salts. It is preferred that the stabilizers are contained in the disinfectant concentrate according to the invention in a concentration of 0.01 to 2% by weight.
For certain applications it may be desirable for the disinfectant concentrate according to the invention to contain an agent for improving the fungicidal activity. The preferred agents for this purpose are N-octylisodiazol-3-one and / or benzoic acid and / or salts of these compounds. These agents for improving the fungicidal activity are preferably present in a concentration of 0.1 to 3% by weight in the disinfectant concentrate according to the invention.
The water content of the disinfectant concentrate according to the invention is typically in the range from 40 to 99% by weight, preferably 60 to 95% by weight and most preferably 80 to 90% by weight.
The pH of the disinfectant concentrate according to the invention is normally 0 to 6 and preferably 0.5 to 2.5.
The invention also relates to the use of the liquid disinfectant concentrate for producing a ready-to-use disinfectant solution by dilution with water. For this purpose, the concentrate according to the invention is usually diluted to 20 to 400 times its volume with water. The diluted, ready-to-use disinfectant solution thus produced typically has a pH in the range from 2 to 4. It is suitable for disinfection in a wide variety of areas. Examples are surfaces, devices, instruments, materials in the medical-medical area, in the industrial and commercial area (e.g. breweries, dairies, slaughterhouses, pharmaceutical companies, food businesses), in the household, kitchen, sanitary area and in the veterinary area . The finished disinfectant can, among other things can be used in the following ways: spraying, wiping, pouring, dipping, inserting, high-pressure processes, wet wipes. The disinfectants can be used for cleaning, disinfectant cleaning, disinfection, germ reduction. The disinfectants can be used in combination with suitable cleaning agents or other disinfectants. The disinfectant solutions according to the invention are broadly effective, for example against bacteria, fungi, yeasts, mycobacteria, enveloped and non-enveloped viruses, both against vegetative germs and against their permanent forms.
Dyes, fragrances and corrosion inhibitors can also be added to the disinfectant concentrate according to the invention.
The invention is explained in more detail below with the aid of examples.

A clear disinfectant concentrate was obtained from the components mentioned. Working dilutions containing 3, 2 and 1 vol% of the concentrate were prepared from the concentrate by dilution with water.
The working solutions of different dilutions were examined in the suspension test according to the "Guidelines for the Testing and Evaluation of Chemical Disinfection Processes of the German Society for Hygiene and Microbiology (see ; Volume 172, Issue 6 (1981)).
The experiments were carried out with Candida albicans and with Aspergillus niger. They were carried out with and without protein contamination, the latter with 10% bovine serum.
The results are shown in Table II below. It can be seen from the table that this disinfectant had an improved fungicidal activity.<tables id="tabl0002" num="0002"><table frame="all"><title>Table II</title><tgroup cols="4" colsep="1" rowsep="0"><colspec colnum="1" colname="col1" colwidth="39.37mm" /><colspec colnum="2" colname="col2" colwidth="39.37mm" /><colspec colnum="3" colname="col3" colwidth="39.37mm" /><colspec colnum="4" colname="col4" colwidth="39.37mm" /><thead valign="top"><row><entry namest="col1" nameend="col1" /><entry namest="col2" nameend="col2" align="center">Use conc.

Examples 9 to 13
Disinfectant concentrates with compositions according to Table III were produced. Low-odor concentrates were obtained, the visual nature of which is shown in Table III immediately after preparation. Samples of these concentrates were kept at room temperature (RT) and at a slightly elevated temperature (40 °) for 9 months. Table III shows the change in the KHSO₅ content as a function of the storage temperature and the time. In addition, the visual condition is given after 9 months.
Examples 9 to 13 show that a low chloride content in the concentrate has a favorable effect on the stability. <tables id="tabl0003" num="0003"><table frame="all"><title>Table III</title><tgroup
