Peroxidase Stabilization via Phenoxyethanol in Detergents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergent and cleaning agent formulations face challenges in stabilizing enzymes, particularly peroxidases, during dilution, which leads to instability and requires expensive dosing systems or addition of solvents like glycerin or propylene glycol to maintain stability.
Innovation Solution
Incorporating phenoxyethanol into the composition with peroxidases, especially in aqueous solutions, significantly enhances enzyme stability, allowing for longer storage and reduced need for precise dosing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If enzymes are diluted in aqueous solutions, then the cleaning agent can be properly formulated and stored, but the enzyme stability decreases over time
Solution Approach 1:
Phenoxyethanol is introduced as an intermediary substance that mediates between the aqueous environment and the enzyme. It acts as a stabilizing agent that allows the enzyme to remain stable in diluted aqueous solutions, eliminating the need for concentrated enzyme formulations while maintaining enzyme activity over time.
Solution Approach 2:
The invention changes the chemical parameter of the aqueous solution by adding phenoxyethanol, which alters the physical-chemical environment to be more favorable for enzyme stability. This parameter change allows the enzyme to maintain its structural integrity and catalytic activity in diluted conditions.
2Stability of the object's composition
If small volumes of enzyme are dosed precisely, then enzyme stability is maintained, but expensive and sensitive dosing stations are required
Solution Approach 1:
The invention replaces expensive, sensitive dosing equipment with a simpler, more robust system that uses phenoxyethanol-stabilized enzyme formulations. The stabilizing agent allows for less precise but cheaper dosing mechanisms while maintaining enzyme stability, effectively substituting complex equipment with a chemical solution.
Solution Approach 2:
Phenoxyethanol serves as an intermediary that decouples the relationship between dosing precision and enzyme stability. By providing chemical stabilization, it allows standard dosing equipment to achieve adequate results without requiring specialized high-precision dosing stations.
3Stability of the object's composition
If solvents like glycerin or propylene glycol are added to diluted enzyme, then enzyme stability is improved, but the formulation becomes more complex and costly
Solution Approach 1:
Phenoxyethanol is presented as a simpler, more cost-effective alternative to traditional enzyme stabilizers like glycerin and propylene glycol. It achieves the same stabilizing effect with a single additive that is easier to work with and less expensive, reducing formulation complexity.
Solution Approach 2:
The invention changes the approach to enzyme stabilization by using phenoxyethanol, which has different physical-chemical properties compared to traditional solvents. This parameter change simplifies the formulation while maintaining or improving enzyme stability.
