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

VSEngineering 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

Engineering Contradiction:
Improvedecontamination effectivenessVSAvoidbroad-spectrum coverage
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #40Composite materials

2Reliability

If different compositions are used for each specific contaminant agent, then targeted decontamination is achieved, but the complexity of the system increases

Engineering Contradiction:
Improvetargeted decontaminationVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If strong oxidants or corrosive agents are used to achieve complete sterilization, then decontamination effectiveness is improved, but safety and environmental compatibility deteriorate

Engineering Contradiction:
Improvesterilization completenessVSAvoidtoxicity and corrosion
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

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

Inventive Principle:
Principle #35Parameter changes

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

Engineering Contradiction:
Improvehand hygiene convenienceVSAvoidsporicidal activity
Core Design Contradiction:
Ease of operationVSReliability

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

Inventive Principle:
Principle #5Merging (Combining)

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.
