Fatty amine polyoxyethylene ether AC-1860 (CAS No.: 26635-92-7), with the chemical name octadecylamine polyoxyethylene (60) ether, also known as octadecylamine polyoxyethylene (60) ether, polyoxyethylene (60) octadecylamine, PEG-60 stearamine, and polyethylene glycol monooctadecylamine ether, etc. This product is manufactured by Hai'an Guoli Chemical Co., Ltd. and belongs to the class of alcohol ether carboxylate nonionic surfactants.
Under conventional conditions, this product behaves as a nonionic surfactant, but in acidic systems, it can transform into a cationic type. This unique amphoteric characteristic enables it to exhibit excellent interfacial activity under various operating conditions. The product typically appears as a light yellow to yellowish-brown solid or paste, facilitating transportation and industrial operations. It has good solubility, being readily soluble in water and various organic solvents, with a pH range of 6.0–8.5 for a 1% aqueous solution.
The core performance advantages of AC-1860 are reflected in four aspects: first, strong emulsifying power, with outstanding emulsifying ability for various oils, waxes, and organic solvents, capable of forming stable emulsions; second, good wetting and spreading properties, effectively reducing interfacial tension and quickly wetting the surfaces of fabrics, metals, or pesticide carriers; third, excellent dispersing performance, maintaining superior suspension and dispersion of pigments and dyes under high temperature and high shear conditions; fourth, high chemical stability, maintaining activity in acidic, alkaline, and hard water systems without easy hydrolysis or failure.

With its diverse functional characteristics, AC-1860 has extensive application value in the following seven major fields:
1. Textile Dyeing and Printing Leveling Agent: In high-temperature high-pressure or normal-temperature dyeing processes, it exerts excellent retarding and migrating effects, effectively reducing color spots and streaks, and significantly improving the leveling effect on fabric surfaces. It is recommended for use as a key component in scouring and dyeing auxiliaries and leveling agents.
2. Industrial and Household Detergents: It has strong emulsifying and detergency capabilities for various oily soils, with moderate foam and easy rinsing, suitable for liquid detergent formulations such as laundry detergents and kitchen and bathroom cleaners.
3. Metalworking Fluids and Rust Inhibitors: As an emulsifier and anti-rust component, it can improve the lubricity and cooling performance of cutting fluids, forming a protective film on metal surfaces to effectively inhibit inter-process corrosion.
4. Pesticide Emulsifier: It can be used to prepare stable emulsifiable concentrates or microemulsions, enhancing the dispersion and spreading properties of pesticide emulsions, promoting wetting of plant leaf surfaces, and improving pesticide utilization and control efficacy.
5. Chemical Fiber Finishing Oil and Antistatic Agent: It effectively reduces the friction coefficient between fibers and metals, eliminates static electricity accumulation during synthetic fiber processing, improves the smoothness of spinning, drawing, and other processes, while providing lasting antistatic finishing effects.
6. Leather Degreasing Agent: It has good penetration and removal effects on natural oils in raw hides, with gentle degreasing action, leaving the leather soft and without grain looseness after treatment.
7. Industrial Emulsifying and Dispersing Agent: Suitable for the dispersion of pigments and fillers in water-based systems and for emulsion polymerization processes, providing long-term dispersion and emulsification stability for coatings and adhesive systems.
