Laundry Detergent Composition with Renewable Surfactants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry detergents with renewable ingredients fail to match the performance of traditional detergents, lacking sufficient concentration of renewable components while maintaining consumer-acceptable cleaning standards.
Innovation Solution
A laundry detergent composition comprising 1-20% alkyl ether sulfate, 1-15% fatty alcohol ethoxylate, 0.1-5% amine oxide, and 0.1-5% cleaning polymer, with 1-15% 1,2-propanediol, and being substantially free of dyes and brighteners, which provides a transparent or translucent formulation with high light transmittance and effective chlorine scavenging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If renewable ingredients are used in laundry detergent, then environmental friendliness is improved, but cleaning performance deteriorates
Solution Approach 1:
The patent combines multiple renewable surfactant types (alkyl ether sulfate, fatty alcohol ethoxylate, amine oxide) with cleaning polymers and solvents to create a composite formulation that achieves both environmental friendliness and consumer-acceptable cleaning performance, resolving the contradiction between renewable ingredients and cleaning effectiveness
Solution Approach 2:
The patent optimizes the concentration ranges of each renewable component (e.g., 1-20% alkyl ether sulfate, 1-15% fatty alcohol ethoxylate) to achieve maximum cleaning performance while maintaining environmental benefits, demonstrating parameter changes to resolve the performance contradiction
2Quantity of substance
If high concentration of renewable components is used, then sustainability is improved, but formulation stability deteriorates
Solution Approach 1:
The patent defines specific concentration ranges for each renewable component that balance high sustainability with formulation stability, showing that optimized parameters can simultaneously achieve both high renewable content and stable composition
Solution Approach 2:
The combination of multiple renewable surfactants with complementary properties creates a synergistic formulation that maintains stability at high renewable component concentrations, resolving the contradiction between quantity and stability
3Object-generated harmful factors
If traditional synthetic surfactants are replaced with renewable surfactants, then biodegradability is improved, but cleaning effectiveness deteriorates
Solution Approach 1:
The patent creates a composite of multiple biodegradable renewable surfactants that work synergistically to achieve cleaning effectiveness comparable to traditional synthetic surfactants, resolving the contradiction between biodegradability and cleaning power
Solution Approach 2:
The renewable surfactant system performs multiple cleaning functions (surfactancy, emulsification, soil suspension) that were traditionally handled by different synthetic components, demonstrating multi-functionality that maintains effectiveness while improving biodegradability
