Peroxyphthalic Acid Compositions for Surface-Compatible Sporicidal Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antimicrobial compositions are ineffective against bacterial spores, often irritating or toxic to users, and environmentally unfriendly, lacking compatibility with applied surfaces.
Innovation Solution
Formulating antimicrobial compositions using peroxyphthalic acids and salts synergistically combined with synergistic additives such as acids, surfactants, solvents, and antimicrobial metals, which are non-corrosive, safe, and environmentally friendly, with pH adjusted to less than 6, optionally in dry or liquid form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chlorine compounds are used as sporicidal ingredients, then effectiveness against bacterial spores is improved, but user safety and environmental friendliness deteriorate due to irritation and toxicity
Solution Approach 1:
The patent changes the chemical parameters by using peroxyphthalic acid instead of chlorine compounds, maintaining sporicidal effectiveness while eliminating the harmful irritation and toxicity associated with chlorine-based agents
Solution Approach 2:
The patent converts the previously harmful chlorine compounds into beneficial peroxyphthalic acid compositions that achieve the same sporicidal effect without the adverse health and environmental impacts
2Reliability
If higher concentrations and elevated temperatures are used for sporicidal activity, then effectiveness against bacterial spores and prions is improved, but surface compatibility deteriorates due to corrosion
Solution Approach 1:
The patent changes the chemical composition to peroxyphthalic acid, which achieves sporicidal and prion effectiveness without requiring the high concentrations and temperatures that cause corrosion, and explicitly states the composition is non-corrosive to surfaces
Solution Approach 2:
The patent creates a composite formulation combining peroxyphthalic acid with synergistic additives that enhance effectiveness against spores and prions while maintaining surface compatibility and preventing corrosion
3Ease of manufacture
If conventional antimicrobial agents are used, then ease of formulation is improved, but effectiveness against bacterial spores deteriorates
Solution Approach 1:
The patent formulates a composite composition using peroxyphthalic acid combined with synergistic additives from categories including acids, solvents, surfactants, and antimicrobial metals, achieving sporicidal effectiveness while maintaining formulation feasibility
Solution Approach 2:
The patent merges peroxyphthalic acid with multiple classes of synergistic additives to create a unified composition that achieves sporicidal activity, combining the benefits of different ingredient categories into a single effective formulation
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 compositions effectively reduce microbial loads on surfaces by at least 1-5 log10, are safe for users, and environmentally friendly, without objectionable odors, suitable for hard and soft surfaces, including healthcare and institutional applications.
Implementation Method 1
The inventor has surprisingly found that a class of compounds, namely, peroxyphthalic acids and salts thereof, act synergistically with a number of other compounds (referred to herein collectively as 'synergistic additives') such that they can be used to make effective antimicrobial compositions
