Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detergents face issues with high surfactant consumption, environmental pollution, and skin irritation due to high viscosity and harshness, as well as secondary precipitation of contaminants on cleaned surfaces, which reduces their effectiveness and safety.
Innovation Solution
The use of polysaccharide microgels as antiresorption agents, thickeners, and interphase tension reducers in detergents, which form stable films to prevent reprecipitation of contaminants and reduce the need for additional surfactants, thereby lowering surfactant concentrations while maintaining detergency and improving skin safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If high concentrations of surfactants are used to increase viscosity, then viscosity is improved, but skin irritation increases and environmental harm worsens
Solution Approach 1:
The patent introduces a polysaccharide thickening agent as an intermediary substance to increase detergent viscosity without using high concentrations of surfactants. This mediator allows the detergent to achieve the necessary viscous, gel-like consistency while avoiding the skin irritation and environmental harm associated with high surfactant levels.
2Force
If high concentrations of surfactants are used to increase viscosity, then viscosity is improved, but environmental pollution increases
Solution Approach 1:
The polysaccharide thickening agent serves as an environmentally friendly intermediary that enables viscosity enhancement without relying on high surfactant concentrations. This mediator reduces environmental pollution while maintaining the detergent's physical properties.
3Quantity of substance
If antiresorption agents are added to reduce surfactant consumption, then surfactant consumption is reduced, but detergent viscosity decreases
Solution Approach 1:
The patent combines the functions of antiresorption agents and thickening agents into a single polysaccharide component. This merged substance simultaneously reduces surfactant consumption by preventing contaminant reprecipitation and maintains detergent viscosity through its gel-forming properties.
Solution Approach 2:
The polysaccharide substance performs multiple functions: it acts as an antiresorption agent to reduce surfactant consumption, serves as a thickening agent to maintain viscosity, and provides skin-friendly properties. This multi-functional approach eliminates the trade-off between reducing surfactant use and maintaining viscosity.
4Quantity of substance
If polysaccharide particles are used as antiresorption agents, then surfactant consumption is reduced, but the particles form loose, unstable layers on surfaces
Solution Approach 1:
The patent changes the physical state parameter of the polysaccharide from discrete particles to a gel structure. This parameter change transforms the substance into a continuous, stable matrix that forms reliable films on surfaces, eliminating the instability and loose layer formation associated with particulate forms.
