Octadecylamine Polyoxyethylene Ether AC-1815 (CAS No.: 26635-75-6) is an adduct of octadecylamine with 15 moles of ethylene oxide, appearing as a white to light yellow waxy solid or paste. Its molecular structure contains both tertiary amine groups and polyoxyethylene chains. This unique molecular design makes it behave as a non-ionic surfactant under neutral or alkaline conditions, while under acidic conditions, the amine groups can be protonated to form a cationic surfactant, combining the synergistic advantages of both types of surfactants.
The most outstanding performance of AC-1815 is its super emulsifying and dispersing ability, which can significantly reduce oil-water interfacial tension, exhibiting excellent emulsification and dispersion stability for various oils, waxes, and pigments. At the same time, this product possesses triple chemical tolerance - resistant to acid, alkali, and hard water, maintaining high activity in harsh chemical environments without easy precipitation or deactivation, which is difficult for many ordinary non-ionic surfactants to match.
In terms of application functions, AC-1815 also shows good low-foam wetting and spreading properties, excellent leveling and migration effects, and outstanding antistatic performance. It is widely used in various industrial fields such as textile dyeing leveling agents, synthetic fiber oils, metalworking fluids, pesticide emulsifiers, and personal care products.
