Polyetheramine Detergent Composition for Cold-Water Grease Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laundry detergents are ineffective at removing grease stains at low wash temperatures, such as 30°C or below, without compromising the quality or production of detergents.
Innovation Solution
A cleaning composition containing 1% to 70% surfactant and 0.1% to 10% polyetheramine, specifically formulated to enhance grease removal in cold water, comprising polyetheramines derived from reacting a 1,3-diol with alkylene oxide and subsequent amination or reductive cyanoethylation, which are added to the detergent to improve cleaning performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surfactants are used in cold water washing, then detergent production and quality are maintained, but grease stain removal effectiveness deteriorates
Solution Approach 1:
The patent combines conventional surfactants with polyetheramine compounds to create a composite detergent system. The polyetheramine (specifically those with molecular weights of 100-1000 g/mol and specific structural formulas) works synergistically with surfactants to enhance grease removal at low temperatures while maintaining detergent quality and production processes
Solution Approach 2:
The invention changes the chemical composition parameters of the detergent by introducing polyetheramine compounds with specific molecular weight ranges (100-1000 g/mol) and structural characteristics (formulas I and II with specific R groups and amination degrees). This parameter modification enables effective grease removal at cold temperatures without compromising detergent quality
2Productivity
If aliphatic amine compounds are added to improve low-temperature cleaning, then grease removal is enhanced, but particulate cleaning performance deteriorates
Solution Approach 1:
The patent applies local quality by using polyetheramine compounds with specific localized structural features (formulas I and II with particular R group configurations and amination degrees of 10-50%). This targeted molecular structure provides grease removal enhancement at specific locations (grease-stained areas) without adversely affecting overall particulate cleaning performance
Solution Approach 2:
The invention precisely controls the molecular weight parameter (100-1000 g/mol) and structural parameters (formulas I and II with specific R groups and amination degrees) of the polyetheramine to achieve selective enhancement of grease removal while maintaining balanced particulate cleaning capability
