Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fabric and home care products, such as laundry and dishwashing detergents, lack improved clay dispersing properties and whiteness, as well as suds mileage, compared to esteramines without sulfate groups.
Innovation Solution
A process involving the reaction of alcohols with at least two hydroxy groups, lactams, and sulfuric acid to produce sulfatized esteramines, which are then incorporated into fabric and home care products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If esteramines without sulfate groups are used in fabric and home care products, then the product formulation is simpler, but the clay dispersing properties and whiteness performance are insufficient
Solution Approach 1:
The patent applies composite materials by combining esteramine structures with sulfate groups to create sulfatized esteramines. This composite structure integrates the surfactant properties of esteramines with the dispersing capabilities of sulfate groups, achieving both good clay dispersing properties and improved whiteness performance while maintaining formulation feasibility
Solution Approach 2:
The patent employs parameter changes by modifying the chemical structure of esteramines through sulfatization. By introducing sulfate groups (-OSO3H) at specific positions on the esteramine molecules, the patent alters the chemical parameters to enhance clay dispersing properties and whiteness performance without completely redesigning the formulation
2Ease of manufacture
If esteramines without sulfate groups are used in fabric and home care products, then the manufacturing process is simpler, but the suds mileage is insufficient
Solution Approach 1:
The patent creates composite surfactant molecules by combining esteramine backbones with sulfate group attachments. This composite structure provides both the surfactant functionality needed for suds generation and the sulfate group contributions to suds stability and mileage, achieving improved duration of action without overly complicating the manufacturing process
3Reliability
If sulfatized esteramines are incorporated into fabric and home care products, then clay dispersing properties and whiteness performance are improved, but the product formulation becomes more complex
Solution Approach 1:
The patent manages formulation complexity by making targeted parameter changes - specifically introducing sulfate groups at controlled positions and ratios on esteramine molecules. This approach achieves improved clay dispersing properties and whiteness performance while limiting the increase in formulation complexity through systematic modification rather than complete reformulation
