Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hexyl glyceryl ether and cyclohexyl glyceryl ether, commonly used as antimicrobial agents, undergo oxidative degradation and decomposition over time, especially in high temperature environments, leading to quality stability issues and the generation of unpleasant odors during storage.
Innovation Solution
A method involving a deodorization step where the glyceryl ether-containing product is brought into contact with water vapor in a reduced pressure environment, combined with an addition step of incorporating 0.05 to 0.30 parts by mass of an antioxidant containing d-α-tocopherol per 100 parts by mass of the glyceryl ether product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hexyl glyceryl ether or cyclohexyl glyceryl ether is used as an antimicrobial agent, then high antimicrobial activity is achieved, but oxidative degradation and decomposition occur readily during storage, leading to quality stability problems and unpleasant odors
Solution Approach 1:
The patent applies preliminary action by conducting deodorization treatment during the production process before the product is stored and used. The deodorization step removes low molecular weight components that are precursors to oxidation and degradation, preventing these quality issues from developing during subsequent storage. This proactive approach addresses the stability problem before it manifests during the product lifecycle.
Solution Approach 2:
The patent employs parameter changes by controlling the deodorization process under specific conditions: reduced pressure of 0.1-10 kPa and temperatures of 60-160°C for 1-24 hours. By optimizing these parameters, the process effectively removes unwanted low molecular weight components while preserving the main glyceryl ether compound, thus improving long-term stability without compromising antimicrobial activity.
2Reliability
If hexyl glyceryl ether or cyclohexyl glyceryl ether is used as an antimicrobial agent, then high antimicrobial activity is achieved, but unpleasant odors are generated during storage due to decomposition
Solution Approach 1:
The patent applies the extraction principle by removing harmful low molecular weight components from the glyceryl ether product through deodorization treatment. These extracted components are the source of unpleasant odors and are eliminated before the product enters storage, preventing odor generation without affecting the antimicrobial properties of the main compound.
Solution Approach 2:
The deodorization process is performed as a preliminary treatment during production, removing odor-causing low molecular weight components before storage. This preliminary removal prevents the generation of unpleasant odors during the product's shelf life while maintaining the antimicrobial activity of the glyceryl ether.
3Reliability
If glyceryl ethers with low molecular weight are used, then favorable antimicrobial performance is achieved, but oxidative degradation occurs more readily in high temperature environments
Solution Approach 1:
The patent applies preliminary action by removing low molecular weight components through deodorization treatment before storage. These removed components are more susceptible to oxidative degradation, so their elimination prevents future oxidation issues while preserving the antimicrobial performance of the main glyceryl ether compound.
Solution Approach 2:
The deodorization process uses controlled parameters (reduced pressure of 0.1-10 kPa, temperatures of 60-160°C) to selectively remove degradable low molecular weight components while preserving the stable main compound. This parameter optimization reduces oxidative degradation risk without compromising antimicrobial performance.
