Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry detergents struggle to effectively remove greasy stains, particularly at low wash temperatures, without compromising whiteness or clay cleaning abilities.
Innovation Solution
The use of esteramines and their salts in cleaning compositions, which enhance the emulsification of soil by surfactants, thereby improving grease cleaning performance even at cold water washing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional amine compounds are used to enhance grease removal, then grease cleaning performance is improved, but whiteness and clay cleaning abilities deteriorate
Solution Approach 1:
The patent modifies the chemical structure of amine compounds by introducing ester groups to create esteramines. This structural parameter change enables the compound to provide grease removal enhancement without the negative impacts on whiteness and clay cleaning that characterize conventional amine compounds.
Solution Approach 2:
The esteramine represents a composite molecular structure combining ester and amine functional groups. This composite structure integrates the grease-solubilizing capability of esters with the surface-active properties of amines, achieving grease removal enhancement while avoiding the harmful effects of conventional amine compounds.
2Loss of energy
If low temperature washing is used to reduce energy consumption, then energy cost is reduced, but grease stain removal capability deteriorates
Solution Approach 1:
The invention changes the chemical parameters of the cleaning composition by incorporating esteramines, which have enhanced low-temperature solubilizing properties. This enables effective grease removal at lower washing temperatures, maintaining cleaning productivity while reducing energy consumption associated with hot water washing.
3Productivity
If hot water washing is used to improve grease removal, then grease cleaning performance is improved, but energy consumption increases
Solution Approach 1:
By modifying the chemical composition to include esteramines, the patent enables grease removal at lower temperatures. This parameter change in the cleaning system allows achieving similar grease cleaning performance to hot water washing while operating at lower temperatures, thus reducing energy consumption.
