Cationic Surface-Active Compounds TRIZ Cases
- Laundry Detergent Silicone Deposition via Segmented Surfactant System
A detergent composition containing anionic and nonionic surfactants deposits silicone onto fabric during washing.
- PEG Blend Solvent System for Single Dose Pack Film Stability
Variable molecular weight polyethylene glycol blends maintain film integrity during high solvent loading, preventing premature rupture and contamination.
- Quaternary Ammonium Fuel Additive Anion Hydrophobic Group
Placing a hydrophobic group in the anion overcomes limited detergent performance caused by cationic hydrophobic structures.
- Solid Fabric Softening Composition with Disintegrant System
A solid fabric softening composition uses a salt and acid disintegrant system to release quaternary ammonium compounds.
- One-Piece Detergent Tablet with Composite Water-Soluble Film
A one-piece detergent tablet uses a polymeric water-soluble film to encapsulate multiple surfactant compositions.
