Dodecylamine Polyoxyethylene Ether AC-1215 (CAS No.: 26635-75-6) is a nonionic surfactant synthesized through the addition polymerization of fatty amines with ethylene oxide. Its molecular structure contains both amine functional groups and polyoxyethylene ether segments, endowing the product with unique interfacial activity and multifunctional properties. In acidic media, protonation of the amine groups makes the product behave as a cationic surfactant. This "nonionic-cationic dual characteristic" greatly expands its application range, allowing it to maintain excellent performance over a wide pH range.
The product possesses five core properties: excellent emulsifying ability (effectively reducing oil/water interfacial tension to form stable emulsions), outstanding wetting and penetration properties (promoting liquid spreading on solid surfaces), superior dispersing performance (preventing flocculation and sedimentation of solid particles), resistance to hard water, acids and alkalis, and blending flexibility with both nonionic and cationic characteristics. These features make it an indispensable key auxiliary agent in many industrial formulations.
From a physicochemical perspective, AC-1215 appears as a colorless to light yellow transparent liquid, with a pH of 8-10 for a 1% aqueous solution, a density of approximately 0.95-1.05 g/cm³, a flash point >100°C, it is soluble in water and dispersible in various organic solvents, and has a shelf life of 12 months under recommended storage conditions (5-35°C, cool and dry place).
During the dyeing process of various fibers (cotton, polyester, acrylic, nylon, etc.), AC-1215 acts as an efficient leveling agent. Through its excellent penetration and dispersion capabilities, it ensures uniform adsorption of dye molecules on the fiber surface, effectively reducing color differences and uneven dyeing, thereby improving the first-pass yield of dyeing. Additionally, its antistatic function reduces the surface resistance of fibers, preventing issues such as fiber entanglement, fly waste adhesion, and yarn breakage during processing due to static electricity accumulation. This is particularly suitable for high-speed spinning and weaving processes of synthetic fibers.
In pesticide emulsifiable concentrate (EC) and emulsion in water (EW) formulations, AC-1215 serves as an emulsifying dispersant that effectively reduces the interfacial tension between the oil phase and water phase, ensuring that the pesticide active ingredient, solvent, and additives form a uniform and stable emulsion. The diluted liquid remains evenly distributed over a long period without layering or precipitation, thereby ensuring uniform deposition of active ingredients during field application and improving pesticide utilization. Its resistance to hard water is particularly important in agricultural areas where hard water is used for dilution.
In industrial hard surface cleaning formulations, AC-1215 acts as an efficient solubilizer and wetting agent. It can rapidly penetrate the interface between the dirt layer and the substrate, reduce dirt adhesion, and enhance cleaning efficiency. Suitable for applications such as cleaning metal parts, glass, ceramic surfaces, and food processing equipment. Its resistance to acids and alkalis allows compatibility with acidic cleaning formulations (e.g., rust removal, descaling) and alkaline cleaning formulations (e.g., degreasing, degreasing), providing high flexibility in formulation design.
Used in daily chemical products such as shampoos, conditioners, and body washes, AC-1215 provides excellent antistatic and conditioning functions. Its amine functional groups have good adsorption affinity for hair keratin, forming a smooth protective film on the hair shaft surface, improving wet and dry combability and touch, reducing frizz, flyaways, and static electricity. It is especially suitable for damaged hair repair formulations and anti-static care products in winter.
In metalworking fluid formulations such as cutting fluids, grinding fluids, and rolling fluids, AC-1215 provides dual functions of emulsification and rust prevention. On one hand, it uniformly emulsifies base oils and functional additives into a stable working fluid, ensuring lubrication and cooling performance during processing; on the other hand, its amine groups form a dense adsorption film on metal surfaces, effectively inhibiting corrosion of ferrous metals such as cast iron and carbon steel by water molecules and oxygen. This is particularly critical for in-process rust prevention of machined parts.
In industrial applications such as acidic cleaning, pickling, and acidic medium treatment, AC-1215 utilizes its cationic characteristics upon amine protonation to act as a solubilizing auxiliary agent. It improves the compatibility and solubility of various components in the system, preventing the active ingredients from layering or precipitating out. It is particularly suitable for industrial applications requiring uniform stability of formulations under acidic conditions.
