Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergents do not fully leverage the cleaning power of enzymes, despite the incorporation of polymers and enzymes, indicating a need for improved cleaning efficacy.
Innovation Solution
A composition containing an amino group-containing copolymer derived from specific monomers and a polyalkylene glycol chain, combined with an enzyme, enhances cleaning power by optimizing the structural units and proportions of these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional polymers (polyethyleneimine ethoxylate) are used as detergent builders with enzymes, then cleaning power is improved, but there is still room for improvement in cleaning power
Solution Approach 1:
The patent modifies the polymer structure by changing parameters such as introducing a polyalkylene glycol chain-containing monomer unit and controlling the ratio of amino group-containing monomer units to total monomer units (0.1-1.0 mol%), thereby optimizing the polymer's interaction with enzymes and improving cleaning power
Solution Approach 2:
The invention creates a composite system by combining specifically designed copolymers with enzymes in a detergent composition, where the copolymer contains structural units (a) from amino group-containing monomers and structural units (b) from polyalkylene glycol chain-containing monomers, achieving synergistic enhancement of cleaning power
