Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a hard surface cleaning composition with a good environmental profile that provides effective emulsification and oily soil removal without compromising consumer satisfaction and/or product appeal, and existing technologies fail to address the challenges of temperature stability and product appeal, including the challenges of temperature stability and product appeal.
Innovation Solution
A liquid detergent composition comprising a surfactant system comprising a specific combination of anionic surfactants, polyethylene oxide, and betaine, with a surfactant system free of alkylbenzene sulphonates, and a weight ratio of surfactants optimized for temperature stability and cleaning efficacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polyethylene oxide and betaine are used in liquid detergent formulations, then emulsification and oily soil removal properties are improved, but temperature stability deteriorates
Solution Approach 1:
The patent modifies the chemical composition parameters by introducing a specific anionic surfactant system (surfactants A and B with defined formulas and ratios) to replace or supplement polyethylene oxide and betaine. This parameter change maintains emulsification and oily soil removal properties while achieving temperature stability across different storage conditions.
Solution Approach 2:
The patent creates a composite surfactant system combining multiple surfactant types (anionic surfactants A and B with specific chemical structures) that work synergistically. This composite approach provides both the desired cleaning performance (emulsification and oily soil removal) and temperature stability that individual components could not achieve alone.
2Reliability
If alkylbenzene sulphonates are used, then cleaning efficacy is improved, but environmental profile deteriorates
Solution Approach 1:
The patent extracts and removes alkylbenzene sulphonates from the formulation entirely, replacing them with environmentally friendlier anionic surfactants (surfactants A and B) that maintain cleaning efficacy while reducing environmental harm. This extraction eliminates the harmful component while preserving the functional performance.
Solution Approach 2:
The patent changes the chemical identity parameter of the surfactant system by substituting alkylbenzene sulphonates with alternative anionic surfactants having different molecular structures (formulas I and II). This parameter change maintains cleaning efficacy through equivalent or superior surfactant activity while improving the environmental profile by selecting biodegradable or less toxic alternatives.
3Object-affected harmful factors
If total amount of surfactant is lowered, then environmental profile is improved, but cleaning efficacy deteriorates
Solution Approach 1:
The patent optimizes the concentration parameter of surfactants in the formulation, finding the minimum effective amount that delivers adequate cleaning performance while minimizing environmental impact. The specific anionic surfactant system (A and B) achieves higher cleaning efficiency per unit mass, allowing lower total surfactant levels without sacrificing cleaning efficacy.
Solution Approach 2:
The patent uses a composite surfactant system where multiple surfactant components (A and B) work synergistically to enhance cleaning efficacy at lower concentrations. This composite approach maximizes the cleaning performance per unit of surfactant, enabling reduced total surfactant content while maintaining or improving cleaning effectiveness.
4Ease of manufacture
If clear and transparent product formulation is used, then product appeal is improved, but temperature stability deteriorates
Solution Approach 1:
The patent adjusts the chemical composition parameters by incorporating a specific anionic surfactant system that is compatible with clear and transparent formulations. This parameter change allows the product to maintain aesthetic appeal (clear and transparent appearance) while achieving temperature stability through the improved surfactant chemistry that prevents clouding and sedimentation across temperature variations.
