Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new materials that can be used in aqueous applications such as laundry and dish care, particularly for stain removal, anti-deposition, anti-graying, and whiteness performance, which are biodegradable and made from renewable resources.
Innovation Solution
A laundry and dish care composition comprising a poly alpha-1,6-glucan derivative with a backbone of glucose monomer units linked via alpha-1,6 glycosidic linkages, optionally with alpha-1,2 and/or alpha-1,3 glycosidic linkages, and substituted with organic groups through a linkage moiety, having a weight average degree of polymerization of at least 5 and a degree of substitution of 0.001 to 3.00.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cleaning agents are used for stain removal and whiteness performance, then cleaning effectiveness is achieved, but environmental sustainability and biodegradability are compromised
Solution Approach 1:
The patent modifies the chemical structure of polysaccharides by changing substitution parameters (degree of substitution, type of organic groups, linkage moieties) to achieve both effective cleaning performance and biodegradability. The poly alpha-1,6-glucan derivative with specific substitution patterns provides the needed cleaning effectiveness while maintaining environmental sustainability.
Solution Approach 2:
The invention creates composite molecular structures by combining polysaccharide backbones with organic groups through linkage moieties. This composite approach allows the material to exhibit both the biodegradability of natural polysaccharides and the effective cleaning properties of modified polymers.
2Reliability
If polysaccharide derivatives are used as rheology modifiers and emulsion stabilizers, then functional performance is improved, but solubility and dispersibility in aqueous solution may be compromised
Solution Approach 1:
The patent applies local modifications to the polysaccharide structure by introducing organic groups at specific positions and controlling the degree of substitution. This localized modification approach allows the material to maintain solubility and dispersibility in aqueous solutions while achieving the desired rheological and emulsion stabilizing functions.
Solution Approach 2:
By carefully controlling substitution parameters (degree of substitution from 0.001 to 3.00, type of organic groups, linkage moiety structure), the patent optimizes both functional performance and aqueous solubility/dispersibility of the polysaccharide derivative.
