Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antimicrobial cleansing compositions, particularly those with silver compounds, face challenges in achieving effective biocidal activity against both gram-positive and gram-negative bacteria within short contact times while maintaining aesthetic properties and controlling costs, especially at low silver concentrations.
Innovation Solution
An antimicrobial cleansing composition comprising 1 to 85 wt% fatty acid soap, 0.1 to 100 ppm silver(I) compound, and 0.1 to 10 wt% non-metal salt of carboxylic acid, which enhances antibacterial activity even at low silver concentrations and provides broad-spectrum control against bacteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silver compound is used at higher concentrations to achieve effective biocidal activity, then antimicrobial efficacy is improved, but cost increases and aesthetic properties deteriorate due to discoloration
Solution Approach 1:
The patent changes the chemical parameters by introducing a carboxylic acid salt component that modifies the chemical environment to enhance silver's antimicrobial activity at lower concentrations, thereby reducing discoloration while maintaining efficacy
Solution Approach 2:
The patent creates a composite antimicrobial system combining silver compound with carboxylic acid salt (such as sodium benzoate or potassium sorbate), where the combination produces synergistic effects that improve biocidal activity while allowing lower silver concentrations
2Quantity of substance
If silver compound is used at lower concentrations to reduce cost and improve aesthetics, then cost and aesthetic properties are improved, but biocidal activity decreases
Solution Approach 1:
The patent modifies the chemical parameters by adding carboxylic acid salt which changes the chemical environment to enhance silver's effectiveness, allowing lower silver concentrations to achieve the same biocidal activity
Solution Approach 2:
The carboxylic acid salt acts as an intermediary or synergistic agent that enhances the biocidal activity of silver compound, enabling lower silver concentrations to achieve effective antimicrobial action
3Reliability
If contact time is extended to achieve biocidal action against gram positive bacteria, then antimicrobial efficacy is improved, but productivity decreases
Solution Approach 1:
The patent changes the chemical composition parameters by incorporating carboxylic acid salt which accelerates the biocidal action, enabling effective gram positive bacteria control within shorter contact times suitable for productivity requirements
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
