For example, disinfection of surfaces, equipment, air, water and applications in human hygiene can be envisaged here, in short, any application for which hydrogen peroxide is suitable.

Description

Technical Field

[0001] This invention relates to stabilized hydrogen peroxide. It also relates to methods for its preparation and its use as a disinfectant, biocide, detergent, bleach, crop protectant, signal transducer, and for degrading crop protectants and pharmaceuticals to maximum residue limits. Background Technology

[0002] In agricultural and horticultural water systems, water contains numerous contaminants such as fertilizers, crop protectants, and microorganisms. These substances form nutrient sources for biofilms, in which microorganisms can easily colonize and proliferate. In long-water systems, such as glass gardening, strong disinfectants or cleaners are needed to remove this biofilm. In (glass) gardening, irrigation systems are typically disinfected using biocides with chlorine or hydrogen peroxide as active substances. Chlorine is usually applied in the form of sodium hypochlorite or chlorine dioxide. However, this water will come into contact with the crops again, and therefore the agent must be present at a low concentration so that the biofilm is removed without harming the crops.

[0003] To achieve this requirement, hydrogen peroxide stabilized with various additives such as alcohols, sugars, organic acids, and silver is typically applied. The application of alcohols, sugars, and organic acids is a good solution for surfaces because these highly concentrated residues are removed after cleaning. However, these products are not suitable for irrigation systems for the following reasons:

[0004] - Excessive erosion of the roots

[0005] - The accumulation of organic acids such as acetic acid (compounds with more than 1% carbon) in the system enhances biofilm growth.

[0006] - Biofilms form mucus, leading to blockages.

[0007] In water transport systems, these substances are residual residues that can accumulate in the conduits and then serve as a nutrient source for microorganisms and biofilms.

[0008] Silver-stabilized hydrogen peroxide is one option for solving this problem. Since hydrogen peroxide itself is unstable and reacts with organic materials, it decomposes into water and reactive oxygen species (free radicals), thus requiring stabilization. When these free radicals come into contact with microorganisms, they are oxidized and die.

[0009] The most commonly used silver compounds are water-soluble silver salts. Silver provides extended hydrogen peroxide at low concentrations and is therefore well-suited for use in horticultural irrigation systems. However, the problem with silver (salts) is that when they dissolve, they create toxic nanoparticles. These nanoparticles are absorbed by living organisms. These nanoparticles cannot be filtered out in water systems, leading to exposure to aquatic organisms via wastewater discharge. Crops can absorb silver nanoparticles through their roots, resulting in environmental exposure via crop residues, such as through recycling processes. Finally, silver can be transported to flowers, fruits, and vegetables in the crop's sap stream. This can lead to exposure in humans and animals.

[0010] Sustainable disinfection of water systems must be carried out using stabilized hydrogen peroxide (preferably as stable as silver-stabilized hydrogen peroxide). Additives or combinations of additives must not be harmful to soil life, crops, humans, animals, or the environment. Residues must not enhance biofilm formation, and the hydrogen peroxide must have long-term effectiveness. Finally, additives must not react with concentrated hydrogen peroxide. The concentrated final product must have long-term stability, preferably exceeding 2 years.

[0011] International patent application WO 2010 / 101844 describes a method in which plant material reacts with hydrogen peroxide, wherein the compound decomposes into water and oxygen. This forms an antimicrobial oxidative molecular complex with reactive oxygen species. However, there is a requirement for hydrogen peroxide that is stable in concentrate and has a long shelf life, and which, even when added in low concentrations to an aqueous system, reacts with biofilms and microorganisms without leaving silver (nano) particle residues. Summary of the Invention

[0015] The preferred application is one or more plant extracts coated with one or more non-toxic alcohols (preferably polyols with hydrogen-absorbing properties, more preferably polyols selected from those having three to ten, preferably three to eight, more preferably three to six hydroxyl groups, especially glycerol and sorbitol).

[0016] Another aspect of the invention provides a method for preparing stabilized hydrogen peroxide according to the invention, wherein:

[0017] - Mix one or more antimicrobial plant extracts with water, preferably at a concentration of 0.0001-1%.

[0018] - One or more non-toxic alcohols, preferably polyols with hydrogen absorption properties, are added to the mixture under continuous stirring, and the reaction is carried out at a temperature of 1-70°C, preferably 50-70°C, more preferably about 60°C, preferably at a concentration of 0.001-10%.

[0019] - After mixing, add 1-70%, preferably 30-50%, of hydrogen peroxide to the mixture and mix the whole at room temperature for 2-4 hours, for example 3 hours, while stirring to form hydrogen peroxide stabilized with coated particles of one or more antimicrobial plant extracts.

[0020] If the solubility of the plant extracts is required, they are mixed with water in the first step in an acidic medium with a pH of 0-6, preferably 1-5, and especially 1-3. Of course, after this step, the concentrate can be further diluted until the desired concentrate is obtained for filling flasks, bottles, jerrycans, drums, intermediate bulk containers, or storage tanks.

[0021] Another aspect of the invention provides hydrogen peroxide stabilized in coated particles of one or more plant extracts according to the invention as a disinfectant, biocide, detergent, bleach, crop protectant, signal transducer, and for use in combating or preventing one or more of the group consisting of bacteria, fungi, viruses, algae, protozoa and nematodes, as well as for breaking down crop protectants and pharmaceuticals to maximum residue limits.

[0022] Particularly advantageous is the application of the stabilized hydrogen peroxide according to the invention.

[0023] - As a disinfectant and cleaning agent, it is used to remove biofilms from growing media of indoor and outdoor cultivated crops, such as open field, potting soil, and substrates; to remove nutrient sources on which biofilms, bacteria, fungi, and viruses can grow; and to clean deposits and organic materials from exterior and interior surfaces.

[0024] - Used for treating air, surfaces, and water that may or may not be suitable for human or animal consumption and industrial applications.

[0025] - Used for water treatment and surfaces such as glass, walls, floors, tables, and climate screens.

[0026] - For treating surfaces, materials, equipment, and furniture that may or may not come into direct contact with food or animal feed.

[0027] - Equipment, containers, utilities, and conduits used for handling food or animal feed that may or may not come into direct contact with food or animal feed, including drinking water for humans or animals, in connection with the production, transport, storage, or consumption of such food or animal feed.

[0028] - For human hygiene, applied to or in contact with human skin or scalp, primarily for the purpose of disinfecting the skin or scalp; for veterinary hygiene; for oral or body hygiene or products with antimicrobial properties; for internal and external use, such as on wounds in the mouth, stomach and intestines.

[0029] All of these are carried out, in particular, through periodic and continuous application, soaking, spraying, atomizing, or misting.

[0030] The applications of the stable hydrogen peroxide according to the present invention particularly include:

[0031] - Add to enrich the soil and growing media used for cultivating agricultural and horticultural crops.

[0032] - An oxygen source added to drinking water for humans and animals.

[0033] - Add oxygen to swimming pools, spas, saunas, beauty treatments, and showers.

[0034] - Enriching water and water systems with additional dissolved oxygen, such as in agriculture and horticulture, hydroponics, and vertical agriculture.

[0035] - Treatment of animal (drinking) water and (drinking) water systems,

[0036] -Conduits and components for handling milking equipment and milk tanks,

[0037] - For veterinary applications, such as spaces where animals are handled, fed, processed, or transported, such as animal transport vehicles.

[0038] - Handling surfaces, spaces, materials, water systems, and (medical) aids, as well as other objects or living organisms that can be carriers / transporters of microorganisms and viruses such as COVID.

[0039] - Processing organic materials, such as manure, as part of an energy production process, or processing less harmful nitrogen compounds or separating them from the compounds.

[0040] - Treat water in storage tanks and related water systems to reduce potentially toxic substances such as nitrites;

[0041] In short, hydrogen peroxide is suitable for any application area.

[0042] Hydrogen peroxide stabilized by coating particles of one or more plant extracts according to the present invention can be used as a medicament or medical adjuvant in internal or external medical treatments, which is also part of the present invention.

[0043] The stable hydrogen peroxide according to the present invention can also be incorporated into textiles, paper towels, face masks, paints and other articles or materials for the purpose of producing treated articles with disinfectant properties.

[0044] Hydrogen peroxide reacts with most organic substances. Surprisingly, we have found that antimicrobial plant extracts can form bonds with hydrogen peroxide under specific conditions, making the hydrogen peroxide particles less prone to "decomposition." Furthermore, quite surprisingly, more dissolved oxygen was measured with less hydrogen peroxide decomposition. This means that, once dissolved in irrigation water, the stabilizer also enhances the stability of the oxygen particles.

[0045] It develops a long-term stable environment and exhibits mild reactions with harmful organisms in complex water systems, such as microorganisms (bacteria, fungi, viruses) and biofilms. The result is sustainable irrigation water with healthy dissolved oxygen levels, enhanced soil life development (such as enzymes), and support for healthy crop development through the formation of essential roots, root hairs, and root tips. There is no exposure to harmful residues here.

[0046] The stabilized hydrogen peroxide according to the invention is a solution of hydrogen peroxide coated with one or more antimicrobial plant extracts, preferably at a concentration of 0.1-70%. The stabilized hydrogen peroxide has the properties of being more stable in low concentrations of contaminated water (such as irrigation water) in the range of 1-100 ppm, being more effective against microorganisms, and retaining oxygen in the solution for a longer period in water systems.

[0047] Hydrogen peroxide stabilized by coated particles of one or more plant extracts according to the invention provides a sufficient solution to a long-standing problem: providing a disinfectant that is environmentally friendly and leaves no residue, with long-term stability of at least 2 years, wherein the hydrogen peroxide decreases by up to 2% of a 50% hydrogen peroxide concentrate each year.

[0048] In commercial packaging, hydrogen peroxide must be present at a high concentration, preferably between 0.1% and 70%. For the primary consumers in the agricultural sector, the most common concentrate will be 30%-50%. Ready-made concentrates, suitable directly for surface treatment, primarily contain 1-8% hydrogen peroxide. The product can be packaged in spray bottles (+ / - 100–1000 cc), bottles (+ / - 1 L), oil cans (+ / - 5, 10, 20 L), drums (up to + / - 200 L), and intermediate bulk containers (+ / - 1000 L). Additives or combinations of additives will preferably be present at concentrations between 0.01% and 1%, most preferably between 0.01% and 1%, which is the case for 50% highly concentrated, stabilized hydrogen peroxide; proportionally, these concentrations will be higher or lower for other peroxide concentrations. Application to aqueous systems via continuous dosing will occur primarily at concentrations of 1-100 ppm, but exceptions exist up to 1000 ppm. Shock dosing in water systems typically occurs at concentrations of 0.5%-6%, requiring several hours of contact time to achieve 100% disinfection. In atomized applications, atmospheric hydrogen peroxide concentrations are generally 10-1000 ppm; in large greenhouses, this range is typically around 10-100 ppm, and in enclosed spaces such as laboratories or medical facilities, it is usually between 50-600 ppm. When applied to crops as a spray, the concentration ranges from approximately 0.1-3%, typically 0.5-1%. For surface application, the range is typically between 1-15%, primarily 1-6%. These concentrations refer to hydrogen peroxide content. Most applications will occur in agriculture and horticulture (indoor cultivation, outdoor cultivation, hydroponics, vertical farming, breeding, seed treatment, application on crops, application in water systems, surface treatment of cultivation systems, greenhouse disinfection, maintenance / cleaning / disinfection of climate screens, root treatment, substrate treatment, decomposition of crop protectants, cleaning of filters, etc.), food processing industry, veterinary field, medical field, shipping, aviation, hospitality industry, logistics industry, public places, amusement parks and amusement facilities, (game) fountains, shops, supermarkets, gas stations, sanitation spaces, government agencies, permanent or temporary residences for animals and humans, and sports facilities. Applications mostly occur by spraying onto surfaces, atomizing in the air / space, and dosing in water systems to combat / prevent (cross-)contamination by bacteria, fungi, and viruses, remove biofilms and organic materials and other pollutants / deposits, add oxygen to water or soil, and improve the lifespan of microorganisms and enzymes in or on the body of humans and animals or on the soil / growing medium used for crop cultivation.

[0049] In this application, coated particles should be understood to mean particles with a diameter of 10. -4 - 10 3Nano-coated particles. In this application, antimicrobial agents are understood to mean those active against microorganisms such as bacteria (including vegetative cells, spores, and mycobacteria), fungi (including yeast), and viruses (including bacteriophages). Biofilms are understood to mean a layer of microorganisms adhering to a surface and surrounded by self-produced mucus or mucus generated by organic contaminants. Hydrogen peroxide stabilized with coated particles of one or more antimicrobial plant extracts of the present invention is also referred to as bio-stabilized hydrogen peroxide. Maximum residue limit (MRL) is the maximum amount of crop protectant or pharmaceutical agent permitted to be present in food. Attached Figure Description

[0056] The present invention is illustrated by the following embodiments.

[0057] Example 1. Preparation of hydrogen peroxide using garlic and pepper extracts.

[0058] Mix 100 g of garlic extract and 500 g of pepper extract in 1000 ml of demineralized water; adjust the pH to 2 by adding nitric acid. Add 2000 ml of glycerol while continuously stirring and heat the mixture to 60°C. Mix the whole mixture at 1100 rpm for 6 hours using a top-mounted stirrer.

[0059] The entire mixture is then added to 1000 L of 35% hydrogen peroxide. The mixture is then stirred at 1500 rpm for 3 hours at room temperature. This produces 1000 L of 35% hydrogen peroxide with granules coated with garlic and pepper extracts. The mixture is stable for at least 2 years. This product can be dosed into water systems for biofilm removal and as a disinfectant by removing bacteria, fungi, viruses, algae, protozoa, and / or nematodes.

[0060] Example 2. Preparation of hydrogen peroxide using Magnolia officinalis extract and Platycladus orientalis extract.

[0061] Mix 200 g of Magnolia officinalis extract and 300 g of Platycladus orientalis extract in 2000 ml of demineralized water; adjust the pH to 2 by adding phosphoric acid. Add 1000 ml of sorbitol and 1000 ml of glycerol with continuous stirring and heat the mixture to 60°C. Mix the whole mixture with a top stirrer at 1100 rpm for 6 hours.

[0062] The entire mixture is then added to 1000 L of 50% hydrogen peroxide. The mixture is then stirred at 1500 rpm for 3 hours at room temperature. This produces 1000 L of 50% hydrogen peroxide with coated particles stabilized with Magnolia officinalis extract and Platycladus orientalis extract. The mixture is stable for at least 2 years. This product can be dosed in water systems for the removal of biofilms and as a disinfectant by removing bacteria, fungi, viruses, algae, protozoa, and / or nematodes.

[0063] Example 3. Preparation of hydrogen peroxide using white willow bark extract.

[0064] Mix 100 g of white willow bark extract in 2000 ml of demineralized water. Add 1000 ml of polyethylene glycol while continuously stirring. Mix the mixture with a top-mounted mixer at 1100 rpm for 6 hours.

[0065] The entire mixture is then added to 1000 L of 50% hydrogen peroxide. The mixture is then stirred at 1500 rpm for 3 hours at room temperature. This produces 1000 L of 50% hydrogen peroxide stabilized with coated particles of white willow bark extract. The mixture is stable for at least 2 years, with peroxide decreasing by up to 2% per year. This product can be added to water systems as an oxidizing cleaner to remove minerals, sediments, and biofilms, and as a disinfectant to remove bacteria, fungi, viruses, algae, protozoa, and / or nematodes; as a crop protectant by spraying onto plants to decompose crop protectant residues; and as an oxygen source for water.

[0066] Example 4. Using biologically stabilized hydrogen peroxide (as prepared in Examples 1, 2, or 3) with silver-stabilized hydrogen peroxide... Comparison of the effects of hydrogen peroxide

[0067] Over a six-month period, three identical water systems containing bacteria and fungi were operated in parallel: an untreated water system, a water system with silver-stabilized hydrogen peroxide, and a water system with biologically stabilized hydrogen peroxide.

[0068] During week 18, the test site was closed for Christmas and New Year's Eve, resulting in pump malfunctions that affected dosage. The dosage was 40 ml / m² via a pulse pump connected to the water meter. 3 Measure the following every 7 days: hydrogen peroxide concentration (mg / L), bacterial colony forming units (CFU), and dissolved oxygen (%); the irrigation system starts at the “fertilization unit” and ends at the “crop”.

[0069] Untreated control

[0070] Low dissolved oxygen content (64-91%) inhibits root development.

[0071] A high bacterial count, exceeding 100,000 CFU, enhances biofilm growth: increased biofilm formation stimulates nutrient deposition. This water is unsuitable for irrigation of healthy crops.

[0072] Silver-stabilized hydrogen peroxide

[0073] This water system is cleaner at the start compared to water systems treated with biologically stabilized hydrogen peroxide. Biofilm removal is rapid (week 3). Hydrogen peroxide concentration decreases relatively quickly after the fertilization unit. Dissolved oxygen levels are higher than with untreated hydrogen peroxide because biofilm formation is zero. Bacterial concentration is low, and oxygen is released through reactions with hydrogen peroxide.

[0074] This agent effectively prevents biofilm formation.

[0075] Biologically stable hydrogen peroxide

[0076] The system was very dirty at the beginning, but by week 6, it was comparable to silver-stabilized hydrogen peroxide.

[0077] The concentrations of hydrogen peroxide, bacterial CFU, and dissolved oxygen were significantly different. Compared to silver-stabilized hydrogen peroxide, the stability of hydrogen peroxide was higher at both the fertilization unit and the crop, although the same amount of CFU was measured. This means that less product is needed to control the CFU, a sign of improved stability, as the product only reacts when necessary and does not decompose itself. Furthermore, when hydrogen peroxide decomposition was lower, the level of dissolved oxygen was, on average, higher; this is also a sign of the stability of oxygen particles in water. Compared to stabilization by silver particles, hydrogen peroxide and dissolved oxygen were better retained in the irrigation water solution in the presence of the biological stabilizer.

[0078] This agent is very effective in preventing biofilm formation.

[0079] in conclusion

[0080] Biostabilized hydrogen peroxide effectively prevents and removes biofilms. This controls bacterial growth and produces high dissolved oxygen levels in the water. Surprisingly, no biofilm increase occurs, despite the potential accumulation of biomass in the stabilizer. It is presumed that the biofilm is converted into carbon, which can serve as a nutrient for plants. Compared to silver-stabilized hydrogen peroxide, biostabilized hydrogen peroxide is more stable and poses no risk of exposure to heavy metals.

[0081] Although the invention has been described above with respect to many preparations and applications of biologically stable hydrogen peroxide, it is obvious that the invention is by no means limited thereto. Rather, many variations can be made within the scope of the invention by those skilled in the art.
