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

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

This invention relates to a disinfection method utilizing a disinfectant solution formed in situ by mixing hydrogen peroxide (H2O2) and nitrite (NO2-) in the presence of a special solvent (called a 'stopping agent') that temporarily slows down the chemical reaction. The selected solvent has a boiling point below 100°C (such as alcohols, ketones, or esters). This approach allows for the disinfecting agents to remain active for a longer period during application, making the process more effective, especially for surface, skin, and wound disinfection. Additionally, the invention includes a specially designed device for simultaneously dispensing and mixing the components efficiently.

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

• Disinfection of skin, especially hands, in medical, veterinary, or public health settings
• Wound disinfection without causing dryness or irritation to the skin
• Decontamination of medical devices—especially temperature-sensitive (thermolabile) equipment like endoscope tubes
• Disinfection of food-contact surfaces, packaging, beverage containers or pipelines in food and beverage industries
• Decontamination of seeds, crops, or other agricultural products
• Inclusion in portable disinfectant dispensers for public and professional environments

BenefitsContent extracted from patent full text and abstract with AI.

• Extends the active time window of the disinfectant, making surface coverage and efficacy more reliable
• Maintains high disinfection potency throughout the application process by avoiding premature depletion of reactive agents
• Allows lower initial concentrations of active chemicals, improving cost-effectiveness and safety
• Minimizes potential for skin irritation and dryness, unlike many alcohol-based hand sanitizers
• Effective against resistant forms such as bacterial spores and non-enveloped viruses
• Reduces risk of environmental accumulation of biocides, as active agents are generated only at the point of use and decompose rapidly
• Device design ensures simple, simultaneous, and thorough mixing/application, thus minimizing operator errors
