Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disinfectants used in water systems, such as chlorine and silver-stabilized hydrogen peroxide, are either harmful to crops and the environment or lead to the formation of biofilm, which causes blockages and nutrient accumulation, while hydrogen peroxide instability and silver nanoparticle toxicity pose additional issues.
Innovation Solution
Stabilizing hydrogen peroxide with coated particles of antimicrobial plant extracts, such as those from the Allium and Salicaceae families, combined with non-toxic alcohols like glycerol and sorbitol, to create a long-term stable disinfectant that effectively removes biofilm without harming the environment or leaving toxic residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chlorine or silver-stabilized hydrogen peroxide is used to disinfect water systems, then disinfection effectiveness is improved, but harmful effects on crops, environment, and formation of biofilm increase
Solution Approach 1:
The patent removes harmful stabilizing agents (silver compounds, alcohols, sugars, organic acids) from the hydrogen peroxide formulation. By extracting these toxic components while retaining hydrogen peroxide's disinfectant properties, the solution achieves effective biofilm removal without harmful residues that could damage crops or promote additional biofilm formation.
Solution Approach 2:
The patent employs hydrogen peroxide as a transient disinfectant that decomposes completely into water and oxygen after use. This disposable approach ensures the disinfectant performs its function effectively against biofilm and microorganisms, then disappears without leaving persistent harmful residues in the irrigation system or environment.
2Object-affected harmful factors
If hydrogen peroxide is used without stabilization, then environmental safety is improved, but stability and shelf life deteriorate
Solution Approach 1:
The patent introduces coating particles as intermediary carriers that protect hydrogen peroxide molecules from premature decomposition. These inert coating particles allow hydrogen peroxide to remain stable during storage and transport, then release the active disinfectant when applied to water systems, achieving both stability and environmental safety.
Solution Approach 2:
The patent changes the physical state and delivery mechanism of hydrogen peroxide by encapsulating it in coating particles. This parameter change from free-floating molecules to particle-encapsulated form maintains chemical stability while preserving the ability to decompose into reactive oxygen species when needed for disinfection.
3Duration of action of moving object
If silver compounds are used to stabilize hydrogen peroxide, then long-term effectiveness is improved, but toxic nanoparticle formation increases
Solution Approach 1:
The patent extracts silver compounds from the formulation entirely, replacing them with inert coating particles. This removal eliminates the source of toxic nanoparticle formation while maintaining hydrogen peroxide stability through alternative means, achieving long-term effectiveness without heavy metal contamination.
Solution Approach 2:
The patent replaces persistent silver nanoparticles with transient coating particles that serve their stabilizing function and then can be safely disposed of. The coating particles do not accumulate in the environment or crops like silver nanoparticles, providing temporary stabilization without long-term toxic effects.
4Reliability
If alcohols, sugars, and organic acids are used to stabilize hydrogen peroxide, then surface application effectiveness is improved, but biofilm enhancement and blockage formation increase
Solution Approach 1:
The patent removes organic stabilizing agents (alcohols, sugars, organic acids) from the formulation. By extracting these carbon-containing compounds, the solution eliminates the nutrient source that would otherwise feed biofilm growth and slime formation in irrigation systems, while maintaining surface application effectiveness through alternative stabilization mechanisms.
Solution Approach 2:
The patent converts the potential harm of organic residues into a benefit by using coating particles that prevent hydrogen peroxide decomposition without providing nutrients for biofilm. The stabilization mechanism itself prevents the harmful effect, turning what would be a source of contamination into a protective barrier.

AI summary
The invention relates to hydrogen peroxide stabilized with a coated particle with a diameter of 10−4-10−3 nanometres of one or more antimicrobial plant extracts. These plant extracts are particularly stabilized with a coating of one or more non-toxic alcohols, such as polyols with hydrogen-absorbing properties. The stable hydrogen peroxide according to the invention can be widely applied as disinfectant by removal of bacteria, fungi, viruses, algae, protozoa and/or nematodes. It is for instance possible here to envisage disinfection of surfaces, equipment, air, water and application in human hygiene, in short, any application for which hydrogen peroxide is suitable.
