Abstract
AbstractTwo propoxylated quaternary amine surfactants characterized by two and six average PO adduct numbers (PO‐2 and PO‐6 QA surfactants) were synthesized to investigate the micellar properties of propoxylated cationic surfactants in water/alcohol mixtures. The effect of PPO groups on micelle formation was explored using conductivity, UV–vis spectroscopy, dynamic light scattering techniques. Regular or reverse micellization occur with water or alcohol rich solvent mixtures, respectively. For intermediate composition no micellization occurs. Also the performances in antibacterial and antistatic fabrics were studied. PO‐2 QA surfactant has excellent antibacterial activities against both the Gram‐negative bacterium Escherichia coli and the Gram‐positive bacterium Staphylococcus aureus while both surfactants have good antistatic activity over polyester fabric.
