Solution Overview
Problem
Existing cleaning agents for denatured oil stains, particularly those containing alkali agents, are either ineffective or pose safety hazards, and there is a need for a neutral cleaning agent with enhanced cleaning power that can easily handle stubborn denatured oil stains.
Innovation Solution
A cleaning agent composition comprising a nonionic surfactant with a polyoxyalkylene alkyl or alkenyl amine, a quaternary ammonium salt-type surfactant, a polycarboxylic acid or its salt, and water, with a limited content of anionic surfactant, which provides excellent cleaning power for denatured oil stains without the need for scrubbing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cleaning agents containing alkali agents are used to remove denatured oil stains, then cleaning power is improved, but skin irritation and safety hazards increase
Solution Approach 1:
The patent changes the chemical composition parameters by using a specific ratio of nonionic surfactant (polyoxyalkylene alkyl/alkenyl amine) to cationic surfactant (quaternary ammonium salt), eliminating alkali agents while maintaining cleaning effectiveness through optimized surfactant combination and concentration ratios
Solution Approach 2:
The invention creates a composite cleaning system by combining nonionic surfactant (a1), cationic surfactant (b), and polycarboxylic acid (c) in specific proportions, where the synergistic interaction between these components provides high cleaning power without requiring harmful alkali agents
2Reliability
If traditional scrubbing method with water-soaked sponge is used to remove stubborn stains, then cleaning effectiveness is improved, but convenience and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical scrubbing action with a chemical cleaning mechanism. The foam-forming cleaning agent composition allows stains to be removed through chemical action during soaking, eliminating the need for mechanical friction and scrubbing efforts
Solution Approach 2:
The invention enables preliminary chemical action to occur during the soaking period before rinsing. The cleaning agent works on the stain during the waiting time, so the actual cleaning effect is achieved before any mechanical intervention is needed
