Disinfection Method Comprising a Disinfectant Formed by Reaction of H2o2 and No2 in Situ with Retarded Release of the Active Substance

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method and a corresponding device for disinfecting surfaces using a solution formed in situ by reacting hydrogen peroxide (H2O2) and nitrite (NO2-). A key improvement is the inclusion of a 'stopping agent'—a solvent with a boiling point below 100°C, such as ethanol or isopropanol—which temporarily slows down the reaction, allowing the disinfectant's active agents to be released more gradually and effectively. This enables better coverage and efficacy during surface disinfection, including on skin, wounds, and medical equipment.

Use CasesContent extracted from patent full text and abstract with AI.

• Hand and skin disinfection in healthcare settings, including sporicidal use (effective against bacterial spores, not just vegetative bacteria).
• Wound disinfection as part of medical treatments or first aid procedures.
• Disinfection of thermolabile (heat-sensitive) medical devices, such as endoscope tubing, where traditional heat sterilization is not viable.
• Decontamination of surfaces in food processing, packaging, and agricultural applications, such as crops, seeds, and animal products.
• Sanitization of containers, beverage lines, and related equipment in food and beverage industries.
• General surface disinfection in public spaces, including schools, gyms, transport, and offices, especially during outbreaks of infectious diseases.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables in situ formation of biocidal agents only when and where needed, reducing the risk of harmful exposure and environmental contamination.
• Improved disinfecting efficacy due to the controlled, retarded release of active substances, achieving better sporicidal and virucidal action, including against non-enveloped viruses and bacterial spores.
• Safer for skin application compared to traditional agents; reduces skin dryness and irritation.
• Minimizes waste and chemical consumption because lower initial concentrations can be used while maintaining efficacy.
• Environmentally friendly: The reactants are fully consumed, leaving only benign residues (mainly water and nitrate), with minimal risk of active biocides lingering in the environment.
• The device for synchronized delivery and mixing ensures precise dosing, convenience, and consistent results.
• Modular system allows for incorporation of additional additives, such as fragrances or buffers, to tailor the disinfectant to specific needs.
