Aqueous Sanitizing Composition for Broad-Spectrum Decontamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sanitizing agents are ineffective against spore-forming bacteria, infectious prions, and chemical warfare agents, and lack safety and environmental compatibility for use on living tissues and food products, with existing formulations requiring different compositions for each specific agent and being corrosive or toxic.
Innovation Solution
An aqueous composition comprising 10-40 wt.% ethanol, 0.01-10 wt.% alkalinating agents (such as ammonium or potassium hydroxide), and 0.1-3 wt.% lauric acid salt, with a pH of 10-13, which can be used to sanitize both inanimate objects and living tissues by physically entrapping pathogens and chemical warfare agents, and is non-corrosive and non-toxic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard sanitizing agents (bleach, alcohol) are used to decontaminate surfaces, then pathogen removal is achieved, but they are ineffective against spore-forming bacteria, infectious prions, and chemical warfare agents
Solution Approach 1:
The patent combines ethanol (10-40 wt%), alkalinating agents (0.01-10 wt%), and lauric acid salts (0.1-3 wt%) into a single unified composition that achieves broad-spectrum effectiveness against spores, prions, and chemical warfare agents, resolving the limitation of single-agent sanitizers
Solution Approach 2:
The invention creates a composite sanitizing formulation integrating multiple active components (ethanol, alkaline agents, lauric acid derivatives) that work synergistically to provide reliable decontamination across diverse pathogen types including resistant spores and prions
2Reliability
If different compositions are used for each specific contaminant agent, then targeted decontamination is achieved, but the complexity of the system increases
Solution Approach 1:
The patent develops a universal sanitizing composition capable of decontaminating multiple types of agents (bacterial spores, fungal spores, prions, chemical warfare agents) with a single formulation, eliminating the need for multiple specialized products
Solution Approach 2:
The invention merges the functions of multiple contaminant-specific treatments into one integrated composition containing ethanol, alkalinating agents, and lauric acid salts that collectively address diverse pathogen types
3Reliability
If strong oxidants or corrosive agents are used to achieve complete sterilization, then decontamination effectiveness is improved, but safety and environmental compatibility deteriorate
Solution Approach 1:
The patent modifies the chemical parameters of the sanitizing composition by using ethanol at controlled concentrations (10-40 wt%) combined with alkalinating agents and lauric acid salts, achieving effective decontamination while maintaining pH and composition levels that prevent tissue damage and environmental harm
4Ease of operation
If alcohol-based sanitizers are used for hand hygiene, then ease of operation is improved, but sporicidal action and penetration of protein-rich materials is insufficient
Solution Approach 1:
The patent combines ethanol-based hand sanitizer convenience with sporicidal alkaline agents and lauric acid salts, creating a hand hygiene product that maintains ease of use while achieving complete spore and prion inactivation
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 decontaminates a wide range of pathogens, including bacterial and fungal spores, and chemical warfare agents, providing long-lasting protection without causing harm to humans or the environment, and can be easily prepared and used in various applications.
Implementation Method 1
The present invention provides compositions and methods to improve the decontaminating effect of ethanol by mixing it with GRAS constituents essentially comprising lauric acid salt, alkalinating agents, and water... which can be used to sanitize both inanimate objects and living tissues by physically entrapping pathogens and chemical warfare agents

AI summary
A composition and method are described for sanitizing or otherwise treating a material such as a non-living surface, living tissue, soil or atmosphere which may be contaminated by a toxin, chemical warfare agent, insect, prion, microorganism or other infectious agent. The composition generally includes an aqueous composition mixture that includes: (a) lower alkanol; (b) an alkalinating agent, and (c) a fatty acid salt and/or ester. The components are present in an effective amount to sanitize (or treat) a material (or modifying a chemical contained thereon) to which the composition is applied. Also described are methods of making the composition.
