Octadecylamine Polyoxyethylene Ether AC-1830 (CAS No.: 26635-75-6) is a nonionic surfactant based on fatty amines, possessing dual characteristics of nonionic and weakly cationic properties. This unique molecular structure endows it with excellent interfacial adsorption capacity and broad substrate affinity, making it irreplaceable in multiple industrial fields. The product appears as a light yellow to yellow paste or solid, with form changes depending on temperature, which is a normal physical phenomenon and does not affect performance.
Thanks to its excellent emulsifying dispersibility, chemical stability (maintains stability under acidic, alkaline, and high-hardness water conditions), and good wetting and spreading properties, AC-1830 can stably function across a wide pH range and under complex operating conditions. Additionally, it has good compounding compatibility with anionic, cationic, and nonionic surfactants, laying a foundation for its flexible application in various composite formulations.
From a process adaptability perspective, AC-1830 can serve both as a single-functional additive (such as leveling agent, antistatic agent) for precise action and as a multifunctional component integrated into complex formulation systems (such as pesticide emulsifiable concentrates, metalworking fluids, daily chemical softeners, etc.), achieving multi-effect industrial value with a single agent.
| Application Industry | Specific Process/Use | Functional Description |
|---|---|---|
| Textile Dyeing and Finishing | Leveling Agent | Has excellent retarding and migration ability, helping dyes uniformly dye fibers, reducing color spots and color difference. |
| Textile Dyeing and Finishing | Antistatic Agent | Reduces static buildup during synthetic fiber processing, preventing entanglement and dust attraction, improving spinnability and fabric hand feel. |
| Agrochemical Formulations | Pesticide Emulsifier | Stably disperses oily pesticide technical materials in water to form uniform emulsions, improving efficacy and storage stability. |
| Metalworking and Antirust | Corrosion Inhibitor | Forms a protective film on metal surfaces, inhibiting corrosion from acids, water, and atmosphere, extending the service life of metal materials and workpieces. |
| Metalworking and Antirust | Lubricant | Enhances lubricity during processes like cutting and drawing, reducing friction and processing temperature, improving machining accuracy and surface finish. |
| Daily Chemical Products | Antistatic Agent/Softener | Added to laundry detergents and fabric softeners to reduce static electricity generation in clothing, improving fabric softness and rewettability by adsorbing onto fiber surfaces. |
| Industrial Cleaning | Nonionic Surfactant | Possesses excellent wetting, penetration, and emulsifying power, suitable for metal degreasing, hard surface cleaning formulations, efficient in removing oil stains with low foam and easy rinsing. |
In formulation design, it is recommended to fully utilize the dual-ion characteristics of AC-1830 (predominantly nonionic with weak cationic properties) to achieve differentiated performance. For example, in textile leveling processes, its weak cationic property can be used to enhance affinity to fibers, improving leveling effect; in pesticide emulsification formulations, the nonionic property provides excellent emulsifying dispersibility, while the weak cationic feature enhances adhesion of the spray liquid to plant leaf surfaces.
Due to its good compounding compatibility with anionic, cationic, and nonionic surfactants, it is recommended to use it as a multifunctional synergistic component in complex formulation systems to reduce the variety of additives and simplify formulation structure. In metalworking fluid formulations, it can serve both lubricating and corrosion inhibition functions, achieving multi-purpose use with a single agent.
