Compared with conventional AEO series (such as Pingpingjia, C12-14 fatty alcohol polyoxyethylene ether), the most essential difference of AC-1210 lies in its raw material and molecular structure. Conventional AEO is produced by direct ethoxylation of fatty alcohols and belongs to pure non-ionic surfactants; while AC-1210 uses dodecyl primary amine as the starting raw material. After ethylene oxide addition, the molecule retains a tertiary amine group, giving the product a unique weakly cationic characteristic. This characteristic enables it to form affinity adsorption on negatively charged fibers, metals, skin, and plant leaves, simultaneously exerting non-ionic emulsification and cationic conditioning and antistatic functions in applications.
In terms of chemical stability, AC-1210 maintains excellent surface activity in both acidic and alkaline media, exhibits outstanding hard water resistance, and is not prone to form precipitates with calcium or magnesium ions. This is in stark contrast to anionic surfactants (such as LAS, AES) that are easily deactivated in hard water and acidic conditions, and it also has a wider application range than some non-ionic products that are only stable under alkaline conditions. With an HLB value of about 13.5, AC-1210 is suitable as an O/W emulsifier, while also having a low surface tension of approximately 32 mN/m and a critical micelle concentration of 6.3×10-5 mol/L, indicating its efficient interfacial activity at the usage concentration.
Comprehensive compatibility is another major advantage of AC-1210. Many cationic surfactants will precipitate or antagonize when compounded with anionics, but AC-1210, by virtue of its non-ionic dominated characteristics, can be freely compounded with non-ionic, anionic, cationic, and amphoteric surfactants, significantly enhancing formulation flexibility and functional diversity. It demonstrates irreplaceable synergistic value in fields such as daily chemicals, textiles, and pesticides that require both emulsification and conditioning functions.
