Ionic Liquid Cleaning Composition for Grease Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cleaning products effective for grease removal often have unpleasant odors, necessitating the use of air fresheners or increased effort to compensate for the smell, and typically contain high levels of solvents which are not environmentally friendly.
Innovation Solution
Development of aqueous cleaning compositions that include ionic liquids and amino alcohols, which are environmentally friendly and effective at grease removal with low volatile organic content, reducing the need for solvents and minimizing odor issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional solvents are used for grease removal, then cleaning effectiveness is improved, but unpleasant odor and environmental harm worsen
Solution Approach 1:
The patent changes the chemical composition parameters by replacing conventional organic solvents with ionic liquids and amino alcohols. This substitution maintains grease removal effectiveness while fundamentally altering the volatile organic content profile, thereby eliminating unpleasant odors and reducing environmental harm associated with traditional solvent-based cleaners.
Solution Approach 2:
The invention employs a composite cleaning system consisting of ionic liquids combined with amino alcohols. This composite formulation creates a synergistic effect where the ionic liquid provides strong grease removal capability while the amino alcohol contributes to low VOC characteristics and pleasant odor profile, together resolving the contradiction between effectiveness and environmental friendliness.
2Reliability
If high levels of solvents are used to achieve grease removal, then cleaning performance is improved, but environmental friendliness worsens
Solution Approach 1:
The patent fundamentally changes the solvent system parameters by eliminating high levels of conventional organic solvents. The ionic liquid-based formulation achieves comparable or superior grease removal performance while reducing volatile organic content to minimal levels, thereby resolving the contradiction between cleaning performance and environmental friendliness.
Solution Approach 2:
The invention substitutes the traditional mechanical evaporation-based solvent action with ionic liquid mechanisms that rely on unique solvation properties and amino alcohol interactions. This substitution eliminates the need for high solvent levels and their associated environmental harms while maintaining effective grease removal capability.
3Reliability
If conventional cleaners with unpleasant odor are used, then grease removal is achieved, but user comfort worsens
Solution Approach 1:
The patent changes the olfactory parameters of the cleaning product by replacing conventional solvent systems with ionic liquids and amino alcohols. This composition change eliminates the characteristic unpleasant odors of traditional cleaners while maintaining effective grease removal, thereby improving user comfort without sacrificing cleaning performance.
