Organic Chemistry TRIZ Cases
- Optical Brightening Solutions With Low Anionic Charge Stability
Concentrated aqueous optical brighteners use charge-balanced chemistry to stay storage-stable, avoid membrane filtration, and whiten paper effectively.
- Polyamide Dye Aftertreatment for Chlorine Fastness Without Shade Shift
Thiourea derivative aftertreatment protects dyed polyamide fibers from chlorine damage while preserving shade, light fastness, and stain resistance.
- Textile Cleaning Solvent Composition for Oil-Water Stain Removal
A hydrophilic hydrocarbon solvent with surfactants removes oil- and water-based stains while protecting fabrics and drying quickly.
