Synergistic Ternary Antimicrobial Mixture for Microbial Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antimicrobial agents in the cosmetic, pharmaceutical, and food industries face challenges in achieving effective antimicrobial properties while being toxicologically harmless, stable, odorless, and cost-effective, with a lack of clear correlations between chemical structure and biological activity, toxicological safety, skin compatibility, and stability.
Innovation Solution
A mixture comprising 2-phenoxyethanol and specific alkanediols, such as 1,2-decanediol and 1,2-pentanediol, exhibits a synergistically enhanced antimicrobial effect against difficult-to-combat microorganisms like Aspergillus niger, offering improved preservation and treatment capabilities at lower concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antimicrobial agents are used, then antimicrobial effect is achieved, but toxicological safety and skin compatibility deteriorate
Solution Approach 1:
The patent combines multiple antimicrobial agents (2-phenoxyethanol with at least two different alkanediols) into a synergistic mixture that achieves enhanced antimicrobial effect while maintaining lower individual concentrations of each component, thereby improving toxicological safety and skin compatibility compared to single agents used at higher doses
2Reliability
If higher concentrations of antimicrobial agents are used, then antimicrobial effect is improved, but cost and potential toxicity increase
Solution Approach 1:
The patent merges multiple antimicrobial agents into a synergistic combination where 2-phenoxyethanol works together with at least two different alkanediols, allowing the mixture to achieve superior antimicrobial effect at lower overall concentrations than would be required for individual agents used alone
3Device complexity
If single antimicrobial agents are used, then formulation is simple, but antimicrobial effect against difficult germs is insufficient
Solution Approach 1:
The patent employs a composite formulation consisting of 2-phenoxyethanol combined with at least two different alkanediols, creating a multi-component system that delivers synergistic antimicrobial activity particularly effective against difficult-to-combat microorganisms such as Aspergillus niger, while maintaining reasonable formulation complexity
