Potassium Salt Stabilization for Liquid Detergent Enzyme Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid detergents and cleaning agents face challenges in maintaining enzyme stability, particularly in liquid forms, due to environmental influences, leading to reduced effectiveness over time and potential cloudiness issues with calcium salts.
Innovation Solution
Incorporating potassium salts, such as potassium acetate, into the formulations to enhance enzyme stability without causing significant clouding, thereby maintaining enzyme activity and cold stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid enzyme preparations are used in detergents, then enzyme activity and cleaning effect are improved, but enzyme stability decreases due to environmental influences
Solution Approach 1:
The patent introduces a protective colloid as an intermediary substance that forms a protective barrier around the enzyme molecules in the liquid detergent formulation. This protective colloid acts as a mediator between the enzyme and harmful environmental factors (such as temperature changes, pH variations, and other detergent components), thereby stabilizing the enzyme activity while maintaining the liquid formulation's cleaning effectiveness.
2Reliability
If calcium salts are used to stabilize enzymes, then enzyme stability is improved, but cloudiness occurs during storage
Solution Approach 1:
The patent removes calcium salts from the enzyme stabilization approach and replaces them with alternative stabilizing agents that do not cause cloudiness. By extracting the problematic calcium salt component and substituting it with compatible stabilizers, the formulation maintains enzyme stability while eliminating the harmful clouding effect during storage.
3Reliability
If boric acids or borates are used as stabilizers, then enzyme stability is improved, but undesirable by-products are formed and environmental damage occurs
Solution Approach 1:
The patent replaces boric acids and borates with alternative stabilizing agents that provide the same enzyme stabilization benefit without the harmful by-products and environmental damage. The invention converts the harmful borate-based stabilization approach into a beneficial, environmentally friendly formulation using compatible alternative stabilizers that maintain enzyme activity without forming undesirable by-products.
