Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wash compositions suffer from syneresis, discoloration, and malodor when stored at elevated temperatures, which is a concern during increased handwashing frequency in pandemics, and there is a need for environmentally friendly and biodegradable alternatives.
Innovation Solution
A stable wash composition comprising a mixture of naturally derived and biodegradable sulfated polysaccharides, specifically lambda and iota carrageenan, with a viscosity of 700 to 15,000 cps, formulated to prevent syneresis, discoloration, and malodor even at elevated temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wash compositions are used, then washing function is provided, but syneresis, discoloration and malodor occur during storage at elevated temperatures
Solution Approach 1:
The patent changes the chemical composition parameters by incorporating sulfated polysaccharides (carrageenan, agar, chitosan) at specific concentrations (0.1-5%) and adjusting pH to 3-10, which fundamentally alters the composition's stability characteristics and eliminates harmful storage effects
Solution Approach 2:
The patent creates a composite wash composition combining multiple components: sulfated polysaccharides, surfactants, and optional additives, where the synergistic interaction between these materials provides both cleaning function and thermal stability during storage
2Object-generated harmful factors
If naturally derived and biodegradable sulfated polysaccharides are used, then environmental friendliness is improved, but composition complexity increases
Solution Approach 1:
The patent simplifies the formulation by focusing on specific sulfated polysaccharide types (carrageenan, agar, chitosan) with defined sulfation levels and concentration ranges, making the complex natural materials manageable through standardized parameters
Solution Approach 2:
The patent employs naturally derived, biodegradable polysaccharides that are relatively inexpensive and environmentally benign, accepting their natural variability in exchange for reduced environmental impact and simplified regulatory requirements
3Ease of operation
If viscosity is increased to improve texture, then consumer appeal is enhanced, but syneresis and phase separation occur more readily
Solution Approach 1:
The patent achieves appropriate viscosity (50-5000 cP) through controlled sulfated polysaccharide concentration and molecular weight selection, while using pH adjustment and surfactant composition to prevent phase separation at these viscosities
Solution Approach 2:
The patent uses surfactants and pH adjusters as intermediary substances that mediate between the sulfated polysaccharides and other formulation components, preventing direct incompatibility and phase separation while maintaining desired texture
