Synergistic Microbicidal Composition Using Phenoxyethanol and Dipropylene Glycol Phenyl Ether
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current microbicidal compositions lack synergistic activity against various microorganism strains, requiring higher levels of individual microbicides, which is economically and environmentally inefficient.
Innovation Solution
A synergistic microbicidal composition comprising 2-phenoxyethanol and dipropylene glycol phenyl ether, with a weight ratio ranging from 1:0.01 to 1:27, is used to inhibit microorganism growth in aqueous media, minimizing the need for additional microbicides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If higher levels of individual microbicides are used to achieve effective control of microorganisms, then microbicidal activity is improved, but economic efficiency and environmental safety deteriorate
Solution Approach 1:
The patent combines two microbicides (phenoxyethanol and dipropylene glycol phenyl ether) into a single composition that produces synergistic effects. This merging allows the composition to achieve effective microbicidal activity at lower total concentrations than would be required using individual microbicides alone, thus resolving the contradiction between maintaining reliability and reducing quantity of substance.
Solution Approach 2:
The invention creates a composite microbicidal system by formulating phenoxyethanol and dipropylene glycol phenyl ether together. This composite material leverages the complementary properties of both components to achieve enhanced microbicidal activity, allowing effective control of microorganisms with reduced overall dosage compared to single microbicide systems.
2Reliability
If combinations of microbicides with synergistic activity are developed, then effectiveness against various microorganism strains is improved, but composition complexity increases
Solution Approach 1:
The patent merges two specific microbicides in defined proportions to create a composition with demonstrated synergistic activity against multiple microorganism strains. By selecting and combining only two complementary components rather than complex multi-component formulations, the invention achieves broad-spectrum effectiveness while maintaining relatively simple composition structure.
3Quantity of substance
If lower levels of individual microbicides are used to reduce environmental impact and cost, then economic and environmental benefits are improved, but microbicidal effectiveness deteriorates
Solution Approach 1:
The patent changes the concentration parameters of the microbicide components by formulating them in specific low concentrations that leverage their synergistic interaction. The composition contains phenoxyethanol and dipropylene glycol phenyl ether at optimized low levels that together achieve effectiveness comparable to or exceeding higher concentrations of single microbicides, thus reducing both quantity and maintaining reliability.
