Chemical Properties
Solubility
Highly soluble in water; exhibits excellent solubility
Stability
Chemically stable; shows good stability against acids and alkalis, with strong resistance to heat, hard water, and salts
Compatibility
Compatible with anionic, cationic, and non-ionic surfactants
Performance Characteristics
- Amphoteric Surfactant: High surface and interfacial activity
- Thickening Effect: More pronounced thickening effect than other alkyl betaines when combined with anionic surfactants
- Viscosity Variation: Sharp increase in solution viscosity under acidic conditions, forming viscoelastic solutions or gels
- Foaming Properties: Good foaming and foam-stabilizing properties; reduces irritation caused by anionic surfactants

Production Process
Involves preparation of cocamide and betaine, amidation reaction, and purification steps. Specifically: reacting coconut fatty acid with dimethylamine to produce cocamide; reacting chloroacetic acid with trimethylamine to produce betaine; amidation reaction under specific conditions; and final purification through distillation, crystallization, or other methods.
Safety & Environmental Impact
Safety: Avoid contact with eyes and skin. In case of contact, rinse immediately with plenty of water and seek medical attention.
Environmental: Readily biodegradable and environmentally friendly. Minimize wastewater discharge and environmental pollution during production.
