Stain Removal Agent Using Polymer Adhesion Promoter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stain removal agents fail to effectively remove difficult stains like cocoa, lipstick, turmeric, and underarm stains from textiles without damaging the fabric, and are inadequate for industrial-scale removal of resin, grease, or moss from hard surfaces.
Innovation Solution
A composition containing surfactants, an adhesion promoter such as alkylene styrene copolymers, and active substances like acids, bleaching agents, and hydrophobic solvents, which are released only in the presence of water to prevent tissue damage and enhance stain removal efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strong acids or oxidizing agents are used to remove difficult stains, then stain removal efficacy is improved, but fabric damage increases
Solution Approach 1:
The patent introduces a polymer matrix as an intermediary carrier that holds the active stain-removing substances (acids, oxidizing agents). This matrix acts as a mediator between the harsh chemicals and the fabric, controlling the release and interaction of these substances to maintain efficacy while reducing damage
Solution Approach 2:
The patent changes the physical state and release parameters of the active substances by embedding them in a polymer matrix. The substances are transformed from free, aggressive forms to controlled, sustained-release forms, altering their interaction parameters with the fabric and stains
2Area of stationary object
If conventional cleaning agents are applied to vertical or overhead surfaces, then cleaning coverage is improved, but the agents run off before acting, reducing contact time
Solution Approach 1:
The patent uses a polymer matrix that forms a flexible, adherent film or gel layer on the surface being cleaned. This film structure conforms to surface geometry including vertical and overhead surfaces, preventing runoff while maintaining contact and allowing sustained action of the embedded active substances
3Reliability
If high concentrations of active substances are used to ensure complete stain removal, then stain removal efficacy is improved, but the risk of surface damage increases
Solution Approach 1:
The patent performs preliminary action by pre-embedding the active substances within the polymer matrix during formulation. This allows the substances to be positioned and concentrated where needed (in the matrix structure) before application, enabling controlled deployment at the moment of contact with the stain without requiring high bulk concentrations that would increase damage risk
