Physical Properties
- Appearance: White to light yellow flake solid, slight characteristic odor, no visible impurities.
- Melting Point: 60-65 °C (lit.), melts into transparent liquid without obvious decomposition.
- Boiling Point: >200 °C (lit.), slightly decomposes above boiling point.
- Solubility: Insoluble in cold water, dispersible in hot surfactant solutions, soluble in polar organic solvents, slightly soluble in non-polar solvents.
- Density: 1.08-1.09 g/cm3 (20 °C, lit.), bulk density 500-550 kg/m3.
- Optical Activity: No optical activity, no chiral center.
- Moisture Absorption: Slightly hygroscopic, prone to sticking in high humidity.
- pH Value: 8.0-10.0 (10 g/L, 10% ethanol solution, 20 °C); amine value ≤30 mg KOH/g.
Chemical Properties
- Chemical Category: Fatty acid amide surfactant (CMEA), belonging to alkanolamide series.
- Stability: Stable under normal temperature and pressure, incompatible with strong oxidants and acids, stable in neutral and weakly alkaline environments.
- Acid-Base Property: Weakly alkaline, reacts with strong acids to form salts.
- Hydrolysis: Stable under normal storage, hydrolyzes under strong acid/alkali and high temperature/humidity.
- Photostability: Relatively stable to light, slight discoloration under strong UV does not affect performance.
- Reactivity: Excellent thickening, foam stability and emulsifying properties; compatible with anionic/nonionic surfactants, biodegradable, low-toxic and mild.
