Detergent Composition Segmentation for Enzyme Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Detergent compositions containing both enzymes and bleaching compounds face stability issues due to adverse reactions, leading to performance loss and increased enzyme levels, which increase costs.
Innovation Solution
A detergent composition with two distinct regions, where the enzyme is located in one region and the bleaching compound in another, with a builder comprising amino acid or succinate-based compounds, particularly using methyl-glycine-diacetic acid and its derivatives, to enhance enzyme stability and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the enzyme and bleaching compound are mixed in the same detergent composition, then the cleaning performance is improved, but the enzyme stability deteriorates due to adverse reactions with the bleaching compound
Solution Approach 1:
The detergent composition is divided into two distinct regions: a first region containing the enzyme and a second region containing the bleaching compound. This spatial segmentation prevents direct contact between the enzyme and bleaching compound, thereby maintaining enzyme stability while still allowing both components to contribute to cleaning performance when activated during the washing process.
Solution Approach 2:
A builder compound is introduced as an intermediary substance located in the first region with the enzyme. This builder acts as a protective mediator that reduces the adverse effect of the bleaching compound on the enzyme, enabling the enzyme to maintain its stability and activity even in the presence of the bleaching compound.
2Reliability
If the enzyme and bleaching compound are separated into different regions, then the enzyme stability is improved, but the cleaning performance deteriorates due to reduced interaction between components
Solution Approach 1:
The builder compound serves as a mediator that facilitates enzyme stability while allowing the separated regions to function effectively. The builder in the first region protects the enzyme from potential adverse effects, ensuring that when the detergent is activated, both the enzyme and bleaching compound can perform their cleaning functions without degradation.
Solution Approach 2:
The invention changes the chemical environment parameters by introducing specific builder compounds (such as zeolites, polymers, or organic builders) that modify the local conditions in the first region. These parameter changes create a protective microenvironment for the enzyme that maintains its activity and stability while allowing effective cleaning performance.
3Productivity
If increased levels of enzyme are included in the detergent composition to compensate for instability, then the enzyme performance is maintained, but the manufacturing cost increases
Solution Approach 1:
By segmenting the detergent composition into separate regions for the enzyme and bleaching compound, the invention reduces enzyme degradation and instability. This allows the use of lower enzyme quantities while maintaining the same level of cleaning performance, thereby reducing manufacturing costs without sacrificing productivity.
Solution Approach 2:
The builder compound acts as a protective intermediary that enhances enzyme stability and reduces degradation. This protection allows the enzyme to maintain its performance at lower concentrations, reducing the quantity of enzyme needed in the formulation while preserving the desired cleaning effectiveness.
