Dodecylpolyoxyethylene Ether AC-1210 (CAS No.: 26635-75-6) is prepared from dodecyl primary amine as the starting material through ethylene oxide addition reaction. Its molecular structure contains both polyoxyethylene ether hydrophilic segments and long-chain alkyl hydrophobic groups, while retaining the weakly cationic characteristics of tertiary amine groups. This unique molecular design makes it outstanding in interfacial activity, capable of rapidly reducing interfacial tension and maintaining stable surface activity in various complex systems.
The most notable feature of this product is its "multifunctional integration": it possesses the emulsifying and wetting capabilities of traditional nonionic surfactants, while its weakly cationic nature gives it a natural affinity for negatively charged surfaces. It can form adsorption films on substrates such as metals and fibers, providing additional functions like antistatic, corrosion inhibition, and softening conditioning. This characteristic is relatively rare among similar products, often allowing it to replace multiple single-function additives in formulations.
In addition, AC-1210 maintains good activity in both acidic and alkaline media, with outstanding hard water resistance and low tendency to form precipitates with calcium and magnesium ions. This ensures its reliability in complex water quality conditions and a wide pH range, making it particularly suitable for industrial formulation systems with stringent stability requirements.
