Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for laundry compositions that are biodegradable and effective in removing particulate soils and oily stains, while maintaining good cleaning performance.
Innovation Solution
Laundry detergent compositions incorporating polyaspartate derivatives with at least two different hydrophilic substituents, including a charged hydrophilic group, are used in combination with surfactants and other ingredients, with the polyaspartate derivative comprising aspartate moieties derivatized with hydrophilic groups and optionally succinimide groups, at a level of 0.001 to 20% by weight of the total formulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polyaspartate derivatives with at least two different hydrophilic substituents (including charged hydrophilic groups) are used in laundry detergent compositions, then biodegradability is improved and cleaning performance for particulate soils and oily stains is enhanced, but the formulation complexity increases
Solution Approach 1:
The patent employs composite polyaspartate derivatives containing multiple hydrophilic substituents (charged and uncharged) combined with surfactants and other detergent ingredients. This composite approach enables the material to simultaneously achieve biodegradability from the polyaspartate backbone and effective cleaning performance through the synergistic combination of different hydrophilic groups that interact with both particulate and oily soils.
2Reliability
If polyaspartate derivatives with multiple hydrophilic groups are incorporated at 0.001 to 20% by weight, then effective removal of oily and particulate soils is achieved, but the manufacturing process complexity increases
Solution Approach 1:
The patent specifies a concentration range of 0.001 to 20% by weight for the polyaspartate derivative in the detergent formulation. This parameter optimization ensures effective soil removal performance while managing manufacturing complexity by providing a clear dosage guideline that balances cleaning effectiveness with formulation stability and ease of production.
