Dodecyl Amine Polyoxyethylene Ether AC-1205 (CAS No.: 26635-75-6) is a non-ionic surfactant prepared by ethoxylation reaction (5EO) using dodecylamine as the starting agent. Its molecular formula is C22H47NO5, with a molecular weight of approximately 405.6 g/mol. The product exhibits non-ionic characteristics under conventional conditions with excellent chemical compatibility; when the system switches to an acidic environment, the amine groups in the molecule undergo protonation, exhibiting cationic characteristics, which can significantly enhance the adsorption and affinity to negatively charged substrates.
The product has an HLB value of about 10.8, is easily soluble in water and organic solvents, with a surface tension as low as approximately 29 mN/m (at critical micelle concentration, 25°C), and a critical micelle concentration of about 0.1 mmol/L, exhibiting high interfacial activity. The cloud point is ≥60°C, indicating that it can maintain stable surface activity and dissolution state in medium to high temperature systems. The product has low foam and excellent penetrating power, making it particularly suitable for industrial formulations requiring rapid wetting and low foam characteristics.
