Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concentrated liquid compositions of amines, protonated amines, and quaternary ammonium compounds face stability issues during storage, require volatile organic compounds for solubility, and have low water solubility, leading to inefficiencies and environmental concerns.
Innovation Solution
A water-dispersible solid composition comprising 30-95% polysaccharide and 5-70% amine, protonated amine, or quaternary ammonium compound, absorbed by the polysaccharide, with optional solubilizers, allowing easy dispersion in water without leaving residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If concentrated liquid compositions are formulated with amines, protonated amines, or quaternary ammonium compounds, then high concentration of active ingredients is achieved, but stability is lost during storage especially at high or freezing temperatures
Solution Approach 1:
The patent changes the physical state parameter from liquid to solid, formulating the composition as a solid powder or granule rather than a liquid. This parameter change eliminates the stability issues associated with concentrated liquid formulations while maintaining high active ingredient concentration. The solid form prevents the thickening and pouring problems that occur in liquid formulations during temperature cycling.
Solution Approach 2:
The patent creates a composite material by combining polysaccharide (such as cellulose, starch, or chitin) with the amine, protonated amine, or quaternary ammonium compound. This composite solid formulation maintains high concentration of active ingredients while providing storage stability, as the polysaccharide matrix prevents phase separation and degradation that occurs in liquid formulations.
2Quantity of substance
If concentrated liquid compositions are formulated, then high concentration of active ingredients is achieved, but volatile organic compounds are required for solubility, which are environmentally undesirable
Solution Approach 1:
The patent extracts and eliminates the need for volatile organic compound solvents from the formulation. By switching to a solid polysaccharide-based matrix, the harmful VOC solvents are completely removed from the system, while still achieving high concentration of active ingredients through the solid form and polysaccharide absorption capacity.
Solution Approach 2:
The patent introduces polysaccharide as an intermediary carrier that replaces the need for VOC solvents. The polysaccharide matrix serves as the medium that holds and dispenses the active ingredients, providing solubility and dispersion without requiring harmful volatile organic compounds.
3Quantity of substance
If alkyl quaternary compounds are made water dispersible, then water solubility is improved, but previous attempts leave residues or bulk up the product
Solution Approach 1:
The patent changes the formulation from traditional water-soluble salts to a solid polysaccharide-based matrix. This parameter change provides water dispersibility without the residue problems associated with conventional water-soluble quaternary formulations. The solid form dissolves cleanly in water without leaving unwanted residues.
Solution Approach 2:
The patent creates a composite material where polysaccharide serves as the carrier matrix for the hydrophobic amine or quaternary ammonium compound. This composite structure provides water dispersibility through the polysaccharide component while the active ingredient remains concentrated, avoiding both residue and bulk issues of previous formulations.
4Stability of the object's composition
If solid puck-type compositions are used, then water insolubility is maintained to control dissolution rate, but insufficient material solubilizes for adequate softening effectiveness
Solution Approach 1:
The patent changes the formulation from completely water-insoluble puck-type compositions to water-dispersible solid compositions. This parameter change allows sufficient material to solubilize for adequate softening effectiveness while maintaining controlled dissolution through the solid form. The water-dispersible characteristic ensures adequate softener reaches the fabric without the limitations of completely insoluble formulations.
