摘要:
The present invention provides a stabilized hypohalous acid solution (or formulation thereof), which may be conveniently packaged for sale, or stored for later use on demand. The invention further provides methods of making the stabilized hypohalous acid solution, as well as methods of use for disinfecting mammalian tissue, including wounds and burns, disinfecting or cleansing surfaces, or treating and/or preserving food products and cut flowers, among other uses.
摘要:
The invention provides a skin disinfectant for treating skin with eczema, preventing bacterial proliferation, and removing biofilm. Compositions of the invention include hypochlorous acid, acetic acid, water, and one or more additives or excipients. The formulation process removes metal ions, reduces ionic strength, controls pH, and reduces exposure to air, thus improving stability and lengthening shelf-life.
摘要:
The invention generally relates to compositions of hypochlorous acid (HOCl) and methods of manufacture thereof. In certain aspects, the invention provides air-free compositions of HOCl. In other aspects, the invention provides methods of making HOCl that involve mixing together in water in an air-free environment, a compound that generates a proton (H+) in water and a compound that generates a hypochlorite anion (OCl−) in water to thereby produce air-free hypochlorous acid.

摘要:
An antimicrobial acid formulation for food and farm applications includes an aqueous solution comprising sulfuric acid present in the aqueous solution in a quantity of from about 1% to about 45% by weight and at least one buffering sulfate salt present in the aqueous solution in a quantity of from about 1% to about 10% by weight.
摘要:
This invention relates to methods and apparatus for achieving microbiological control, especially using active sources that generate hypochlorous acid vapor. These methods are effective in confined spaces and sealed containers. The active sources may be contained within permeable containers and may be actively dispersed. The active sources may be in the form of solids, liquids or gels.
摘要:
This invention relates to methods of diluting hypochlorite and hypochlorous acid compositions with purified water to produce stable compositions. These compositions can be used to treat allergen containing surfaces, hard surfaces, food contact surfaces, hospital surfaces, food surfaces, kitchen surfaces, bathroom surfaces, human surfaces, animal surfaces, military equipment, transportation equipment, children's items, plant surfaces, seeds, outdoor surfaces, soft surfaces, air, wounds, and medical instruments.
摘要:
A system and method are disclosed for increasing the concentration of hypochlorous acid in a quantity of water. Acid is injected into chlorinated water to decrease the pH of the chlorinated water. By decreasing the pH, the hypochlorite/hypochlorous acid equilibrium of the chlorinated water is shifted to increase the concentration of hypochlorous acid on the treated water.
摘要:
Improved electrodialysis (ED) stacks are disclosed having one or more components selected from the group:a) cation exchange membranes having ion exchange groups predominantly sulfonic acid groups and a minor amount of weakly acidic and/or weakly basic groups or membranes which are selective to monovalent cations and simultaneously therewith, cation exchange granules selective to monovalent cations as packing in the dilute compartments;b) anion exchange membranes having as ion exchange groups only quaternary ammonium and/or quaternary phosphonium groups and substantially no primary, secondary and/or tertiary amine and/or phosphine groups or membranes which are selective to monovalent anions simultaneously therewith, anion exchange granules selective to monovalent anions as packing in the dilute compartments;c) as packing in the dilute compartment, anion exchange granules which are selective to monovalent anions, or cation exchange granules which are selective to monovalent cations, or cation exchange granules having as exchange groups a predominant amount of sulfonic acid groups and a minor amount of weakly acidic and/or weakly basic groups, or anion exchange granules consisting of organic polymers having as anion exchange groups only quaternary ammonium and/or quaternary phosphonium groups and almost no primary, secondary and/or tertiary amine and/or phosphine groups.
摘要:
A method for providing aqueous solutions of HOBr or HOCl which includes adding bleach (NaOCl) to a solution of HBr or HCl an identified absorbance or color change in the resulting solution is detected. Dialkylhydantoins are optionally added to the resulting solution to suppress the formation of halate ions. The method provides a simple and reliable method for producing accurately defined solutions of hypohalous acids, which are useful in a variety of ways, including for disinfecting, cleaning, and odor control purposes.
