Polyetheramine Cleaning Composition for Cold-Water Grease Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laundry detergents fail to achieve satisfactory cleaning performance at low wash temperatures, particularly in removing grease stains in cold water without compromising detergent quality or affecting particulate cleaning.
Innovation Solution
A cleaning composition containing 1% to 70% surfactant and 0.1% to 10% polyetheramine, specifically polyetheramines of Formula (I) or Formula (II), which are obtained by reacting a 1,3-diol with alkylene oxide and subsequently aminated or undergo reductive cyanoethylation, enhancing grease removal in cold water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surfactants and known additives (aliphatic amines, linear alkoxypropylamines) are used in laundry detergents, then the detergent composition can be formulated, but satisfactory cleaning performance at cold temperatures (30°C and below) cannot be achieved
Solution Approach 1:
The invention changes the chemical structure parameters of the amine component by using polyetheramines with specific molecular weights (100-1000 g/mol) and specific structural formulas (I and II) with controlled amination degrees (less than 50%). This parameter change enables effective grease removal at cold temperatures while maintaining detergent stability
Solution Approach 2:
The invention creates a composite detergent system combining conventional surfactants (anionic and/or nonionic) with a specifically designed polyetheramine component. This composite approach synergistically improves cold-water grease cleaning while the polyetheramine simultaneously stabilizes fragrances and suppresses suds
2Object-generated harmful factors
If high-molecular-weight branched trifunctional primary amines (e.g., Jeffamine T-5000) are used to suppress suds, then suds suppression is achieved, but grease removal at cold temperatures is not improved
Solution Approach 1:
The invention applies local quality by designing polyetheramines with specific structural features (formulas I and II) where only certain portions of the molecule have specific properties. The amination degree is controlled to be less than 50%, creating localized functional regions that provide both suds suppression and enhanced grease cleaning at cold temperatures
Solution Approach 2:
The invention changes the molecular weight parameter to a lower range (100-1000 g/mol) compared to conventional high-molecular-weight amines, and controls the amination degree parameter (less than 50%). These parameter changes enable the dual function of suds suppression and cold-water grease cleaning improvement
3Stability of the object's composition
If linear primary polyoxyalkyleneamines (e.g., Jeffamine D-230) are used to stabilize fragrances, then fragrance stability is improved, but grease removal at low temperatures is not enhanced
Solution Approach 1:
The polyetheramine component described in the invention performs multiple functions simultaneously: it stabilizes fragrances (like Jeffamine D-230), suppresses suds (like Jeffamine T-5000), and enhances grease removal at cold temperatures. This multi-functional additive eliminates the need to choose between fragrance stability and cleaning performance
