Neutral pH Hydrogen Peroxide Cleaning Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ready-to-use cleaning and disinfectant compositions often cause ocular and dermal irritation and lack broad-spectrum disinfection and cleaning efficacy, particularly against gram-positive bacteria like Staphylococcus aureus, and do not provide effective surface cleaning on various soils.
Innovation Solution
A neutral pH (6-8) combination of hydrogen peroxide, a C1-C6 monohydric alcohol, and surfactants, including non-ionic, anionic, cationic, and amphoteric surfactants, which provides broad antiseptic and cleaning properties, with optional additives for stability and foaming agents, forming a 'hospital strength' disinfectant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cleaning and disinfectant compositions are used, then disinfection capability is provided, but ocular and dermal irritation occurs
Solution Approach 1:
The patent changes the pH parameter from acidic to neutral (pH 6-8) and modifies the chemical composition parameters by using hydrogen peroxide combined with specific surfactants instead of traditional acidic disinfectants, thereby maintaining disinfection capability while eliminating skin and eye irritation
Solution Approach 2:
The patent creates a composite disinfecting system combining hydrogen peroxide with non-ionic, anionic, cationic, and/or amphoteric surfactants in specific concentrations, forming a multi-component composition that achieves broad-spectrum disinfection without irritation
2Object-affected harmful factors
If hydrogen peroxide alone is used at neutral pH, then safety is improved, but effectiveness against gram-positive bacteria is insufficient
Solution Approach 1:
The patent merges hydrogen peroxide with multiple types of surfactants (non-ionic, anionic, cationic, and/or amphoteric) in a neutral pH formulation, creating a synergistic combination that enhances antiseptic effectiveness against gram-positive bacteria while maintaining safety
Solution Approach 2:
The patent develops a composite antiseptic system where hydrogen peroxide works in conjunction with specific surfactant combinations, creating a multi-functional composition that achieves both safety and broad-spectrum effectiveness
3Ease of manufacture
If commercial cleaning products are used, then cleaning function is provided, but surface cleaning efficacy on various soils is insufficient
Solution Approach 1:
The patent creates a universal cleaning composition that effectively cleans multiple types of soils (organic, inorganic, oily, greasy) on various hard surfaces through a multi-component surfactant system, providing broad-surface efficacy
Solution Approach 2:
The patent formulates a composite cleaning system combining multiple surfactant types with hydrogen peroxide, where each component contributes to cleaning different soil types, achieving superior overall cleaning performance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively disinfects both gram-positive and gram-negative bacteria and provides superior surface cleaning compared to commercial products, maintaining antimicrobial activity and reducing volatile organic materials while being non-irritating to humans.
Implementation Method 1
hydrogen peroxide is known to be antiseptic under acidic pH. It has disinfectant properties against both gram-positive type bacteria such as Staphylococcus aureus, and gram-negative type bacteria
Implementation Method 2
The combination of the present invention was found to provide effective antiseptic treatment for a wider variety of bacteria than hydrogen peroxide alone at neutral pHs
Implementation Method 3
The surfactant component of the present invention can be non-ionic, anionic, cationic and/or amphoteric or a combination thereof. The combination was also found to provide surface cleaning efficacies on many soils better than currently available commercial cleaning products
