The technical field to which the invention relates.

The invention relates to the field of research of modern highly effective means of decontamination (disinfection) on the basis of environmentally safe oxygen-containing compounds and is intended for protection and decontamination (disinfection) surfaces in hermozamente the volume of various objects.

The level of technology

Protection and disinfection of surfaces in hermozamente volumes of various objects to ensure the sanitary safety of personnel in the process of life and the execution of functional responsibilities is a vitally important task.

There are different approaches to creating decontaminated formulations, capable of forming a protective polymeric coating different surfaces inside hermozamente volumes of various objects depending on their destination.

Known methods for producing decontaminate recipes designed for various decontamination of surfaces contaminated with biological and chemical contaminants. The closest essentially performed the tasks assigned to decontaminable formulation consider destination, is a bifunctional recipe oxidation and nucleophilic action, patent 2248234, l. AV 3/00, 20.03.2005.

Formulations which contains an aqueous solution of inorganic oxidizer, which is peroxosulfates of potassium fluoride. Additionally, the formula includes organic solvent, and high-molecular compounds of cellulose ethers, mainly gidroxiatilzelluloza with the addition of surface-active substances.

The disadvantages of this formulation include the ability of the used inorganic oxidizer during long-term storage become difficult to split the conglomerate. When preparing recipes added additional operations crushing and grinding the resulting conglomerates, increase the cooking time and the solubility of the formulation, which in turn increases the measures of decontamination of surfaces inside hermozamente objects.

The closest analogue to the proposed technical solution to the technical essence and achieved a positive result is dezinficiruy-degassing recipe oxidation and nucleophilic action, patent 2324515, l. A61L 2/15, A62D 3/30, 2008, the Recipe consists of inorganic oxidizer, an organic solvent and gidroxiatilzelluloza with the addition of surfactants. As the inorganic oxidizer use peroxosulfates of potassium fluoride (PFC) or activated modification (PFC), optionally in the Tav inorganic oxidizer introduced anti-caking agent from the group of liquid nonionic surfactants in quantities of 0.5-2.0 wt.% from the mass of the corresponding oxidant. As caking agent suggested to use the following compounds: a mixture monoalkyl esters of polyethylene glycol, a mixture of fermentelos and other drugs nonionic surfactants. The introduction of the inorganic oxidizer mixture monoalkyl esters of polyethylene glycol or a mixture of fermentelos as caking agent not only eliminates the ability of the PFC to caking, but also increase sporicidal properties modifications PFC.

The disadvantage of this formulation for the proposed technical solution is the impossibility of its use for the decontamination of surfaces inside hermozamente volumes, as recommended methods of application of the formulation on the surface are: irrigation or aerosol. Both methods of application decontaminate recipes on the surface in hermozamente volumes of various objects are unsuitable because of the specific requirements for the functioning of these objects.

In the patent 2174847, C1 A61L 15/44, A61L 15/22, 2000, film-forming colorless composition (polyvinyl alcohol, chlorhexidine digluconate, tetraborate, water) possesses antimicrobial activity, satisfactory ductility, dimensional stability upon exposure to 10 days. Also known material, made in the form of a film used in medicine and veterinary medicine for antiseptica the who cover the wounds of different etiology and incorporating polyvinyl alcohol (patent EP 0481600 A2 19920422 IPC A61L 15/28, 2000). The disadvantages of the above technical solutions should include the short duration of the existence of a film coating on the treated surface.

Known for a number of film-forming polymers that can not be destroyed under the influence of various chemical compounds high degree of activity, which include decontaminable funds. The choice of a specific film-forming polymer capable of not deteriorate under the influence of peroxosulfates of potassium fluoride in a certain period of time, to give decontaminate recipe oxidation and nucleophilic action (patent 2324515, l. A61L 2/15, A62D 3/30, 2008), ability to form films, preserving decontaminated activity on the treated surfaces inside hermozamente volumes of various objects for a long time and protects the surface from repeated contamination, is the essence of the problems solved by the proposed technical solution.

We have used a variety of film-forming compounds experimentally tested variants of their quantitative ratios within the actual mixture of organic solvent and within the formulation as a whole.

The technical result of the proposed technical solution is the development of other forms of application decontaminated Retz the ATGM on the basis of peroxosulfates of potassium fluoride and its modifications, able to create a film coating on the surfaces inside hermozamente volumes of various objects while preserving their sporicidal, bactericidal and fungicidal properties within a specified time.

The recipe consists of the following components (in mass percent): peroxosulfates fluoride potassium 1,0; polyvinyl alcohol 1,0-2,0; polyvinylpyrrolidone 1,0; plasticizer (glycerin) 0,5; distilled water to 100.0.

Peroxosulfates of potassium fluoride (PFC) and activated hydroxycarboxylic acid modification (PFC) was used as the inorganic oxidizer.

The proposed structure is characterized by the fact that, as the organic solvent used is a mixture consisting of polyvinyl alcohol (1.0 to 2.0), polyvinylpyrrolidone (1,0) and plasticizer (glycerin) (0,5).

When the content of 2.2% polyvinyl alcohol in the composition of the film decontaminate recipes based peroxosulfates of potassium fluoride as a film coating is not uniform, violated the elasticity of the film coating on the surface of the test sample during the observed period necessary for qualitative research. When removing the film from samples of the test surfaces it is deformed and torn due to the lack of uniformity of the film coating.

Use in the composition of the film formulations instead of various modifications of PFC liquid forms of hydrogen peroxide, at a constant ratio of other ingredients, leads to the production of film coatings with almost similar physico-chemical properties. A distinctive feature is only greater transparency films using liquid hydrogen peroxide, but this fact was predictable. When the solvent evaporates in the process of forming film in recipes based on modifications of peroxosulfates fluoride in the composition of the film is itself Sol PFC.

With increasing PVP content from 1.0% to 10%, decontaminated formulations based peroxosulfates of potassium fluoride, activated peroxosulfates fluoride or potassium liquid hydrogen peroxide while maintaining the quantitative composition of the rest of the ingredients, film coating test surfaces obtained inelastic, less durable and drying cracks. At maximum (10%) the content of the polyvinylpyrrolidone in the composition of the formulations of the film get hard and brittle.

Contents active against organisms of the substance in the finished plenkoobrazuyushchie recipe is (...8,4 3,4)% depending on the selected oxidizing ingredient.

Example 12. Experimental evaluation of antimicrobial activity of the film-forming formulations was performed using a test surfaces contaminated spore and vegetative forms You.cereus. Contaminated suspension spore or vegetative forms You. cereus test surface was dried in an incubator until fully dry. Film-forming decon amineralo recipe based peroxosulfates of potassium fluoride was applied so film to overlap with the area of contamination of the test surfaces. Upon completion of the exposure of each test surface was placed in sterile Petri dishes, removed their film. The test surface was treated with sterile saline repeatedly, the total number of saline 10 ml flush All the fluid was collected in sterile tubes, labelled, and then 1 ml of wash liquid were placed in sterile Petri dishes and filled in sterile nutrient medium (meat-peptone agar). The rest of the wash liquid was placed in the refrigerator, in case of receiving the disputed results of repeating the experiment. The test surface after the flushing procedure was also placed in individual Petri dishes and filled in sterile nutrient medium. In parallel to control decontamination) nutrient medium were filled with contaminated test surfaces, which have not been deposited film decontaminable recipes.

The results showed that the inoculated vegetative and spore forms of You.cereus test surface without processing their film decontaminate recipe at the end of the incubation period (24 hours at 37C) was a solid lawn. The Petri dishes placed in their test surfaces after remote film decontaminatio coverage, individual growth (3...5) colonies ICRI the organisms, preserving the viability of the test surfaces after they are processed film decontaminate formulation based peroxosulfates of potassium fluoride were present on the test surfaces contaminated spore form You.cereus. In wash liquids from these same samples, the growth was almost absent (0...1) colonies.

The Petri dishes placed in their test surfaces after remote film decontaminatio coverage, growth (13...84) colonies of microorganisms that preserved the viability of the test surfaces after they are processed film decontaminate formulation on the basis of hydrogen peroxide, was present on the test surfaces contaminated spore form You.cereus. In wash liquids from the same samples increased (11...56) colonies.

Example 13

In example 12 decontaminable film formulations were applied to previously cleaned and dried test surface. In this example, the test surface is pre-applied film decontaminated recipe based peroxosulfates of potassium fluoride and/or activated peroxosulfates of potassium fluoride. The finished plate was placed in a sterile Petri dish. After drying the film on its surface was applied 0.1 ml of a suspension of spores Bac.subtilis 3(5107SP/ml), a spatula was distributed over the entire surface of the plate. Delaplaine filled MPA (with mushrooms used the environment Saburo) and were incubated at T=37C for 24 hours. Thus formed film does not change the appearance of the metal surface and does not cause corrosion. Sustainable bactericidal result against Bac.subtilis 3 obtained already at a concentration of 1.0 wt.% peroxosulfates of potassium fluoride in a film formulation (content of N2About2to 0.3%). The result after 24 hours of incubation showed clearly that over the area of the film (figure 1) there is no growth of microorganisms, and the film is from 1 to 27 mm. In figure 2 (control) observed a continuous growth of grass after 24 hour incubation.

Also, experiments were carried out on the coating film on the samples of the test surfaces contaminated Trichoderma harrianum. - Candida albicans or Aspergillus niger (Fig.3) the results Obtained, confirming the fungicidal activity of the polymer decontaminate (disinfectant) formulations based peroxosulfates of potassium fluoride to obtain a durable and low permeability films that protect and decontaminated surface in hermozamente the volume of various objects. Effective decontamination of test surfaces contaminated Trichoderma harrianum. - Candida albicans or Aspergillus niger, takes 30-60 minutes.
