Etheramine Laundry Detergent for Cold Water Grease Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laundry detergents fail to achieve satisfactory cleaning at low temperatures, particularly in cold water, and often compromise on grease removal or particulate cleaning.
Innovation Solution
A laundry detergent composition containing 1% to 70% surfactants and 0.1% to 10% etheramines of specific formulas, which enhance grease removal in cold water without affecting detergent quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional surfactants are used in cold water washes, then energy consumption is reduced, but cleaning performance deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the detergent composition by introducing etheramine compounds with specific molecular structures (Formula I and II) that remain chemically active at low temperatures. The etheramine contains hydrophobic groups (R1-R12) and hydrophilic amine groups (Z1-Z4) that enable effective grease removal at cold water temperatures without requiring thermal energy
Solution Approach 2:
The patent creates a composite detergent system combining conventional surfactants with etheramine compounds. This composite formulation leverages the synergistic effects between different cleaning agents - the surfactant provides general cleaning while the etheramine specifically targets grease stains at low temperatures, achieving reliable cleaning performance without hot water
2Reliability
If additives are added to enhance detergent power at low temperatures, then grease removal is improved, but detergent composition complexity increases
Solution Approach 1:
The patent extracts and focuses on a specific functional component (etheramine) that can be added in controlled amounts (0.1% to 10% by weight) to provide targeted grease removal enhancement. This selective addition minimizes composition complexity while achieving the desired improvement in low-temperature grease cleaning performance
3Loss of energy
If low-temperature detergent formulations are developed, then energy savings are achieved, but cleaning effectiveness deteriorates
Solution Approach 1:
The patent modifies the chemical composition parameters by incorporating etheramine compounds with specific structural features (hydrophobic R groups and hydrophilic amine Z groups) that enable effective cleaning at low temperatures. The molecular structure of the etheramine allows it to function effectively without thermal activation, maintaining cleaning effectiveness while enabling energy-saving cold water washes
