Fatty Amine Polyoxyethylene Ether AC-1860 (CAS No.: 26635-92-7) is chemically named Octadecylamine Polyoxyethylene (60) Ether, also known as PEG-60 Stearamine, Polyethylene Glycol Monooctadecylamine Ether, etc. This product is manufactured by Guoli Chemical. Its molecular structure contains a long-chain fatty amine hydrophobic group and 60 polyoxyethylene (EO) hydrophilic units, giving it unique amphiphilic properties.
Under normal conditions, AC-1860 behaves as a non-ionic surfactant, but in acidic systems, the amine group becomes protonated, transforming into a cationic type. This characteristic allows it to function flexibly in different pH environments. The product typically appears as a light yellow to yellowish-brown solid or paste, facilitating transportation, storage, and industrial metering operations. It is easily soluble in water and various organic solvents, and the pH value of a 1% aqueous solution ranges from 6.0 to 8.5.
As a high-performance surfactant, the core competitiveness of AC-1860 lies in its fourfold performance advantages: ① Strong emulsifying power – forms stable emulsions with various oils, waxes, and organic solvents; ② Good wetting and spreading ability – effectively reduces interfacial tension and quickly wets various substrate surfaces; ③ Excellent dispersing performance – maintains excellent suspension and dispersion of pigments and dyes even under high temperature and high shear conditions; ④ High chemical stability – resistant to acids, alkalis, and hard water, not easily hydrolyzed, maintaining activity under complex working conditions.

With its multifunctional properties, AC-1860 has mature industrial applications in the following seven major fields:
Hazard Identification: This product is classified under GHS as Skin irritation (Category 2, H315), Serious eye irritation (Category 2, H319), Toxic to aquatic life – Acute Hazard (Category 2, H401), and Chronic Hazard (Category 3, H412). Signal word: "Warning"; Pictograms: Exclamation mark and Environmental hazard. Acute fish toxicity (96h) LC50 is 1–10 mg/L, do not discharge directly into water bodies.
Operational Protection: Operators should wear chemical safety goggles, chemical-resistant gloves (butyl rubber or nitrile rubber), protective clothing, and protective shoes. When ventilation is insufficient, a face mask or respiratory protective device should be worn. Avoid direct contact with skin and eyes, and wash thoroughly after handling.
Storage Conditions: Recommended storage temperature is 10°C–35°C, in a cool, dry, and well-ventilated place, avoiding freezing and high temperature exposure. Keep containers tightly closed and store separately from strong oxidizing agents and strong acids. Stainless steel, polyethylene, or plastic-lined iron containers are recommended.
