Fatty Amine Polyoxyethylene Ether AC-1860 is a non-ionic surfactant with octadecylamine as the hydrophobic group and 60 ethylene oxide units grafted. It exhibits cationic characteristics in acidic media and is widely used in textile printing and dyeing, industrial cleaning, pesticide formulation, metal processing, and other fields due to its excellent emulsifying, wetting, dispersing capabilities and outstanding chemical stability.

Detailed Description

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.

Application Recommendations

With its multifunctional properties, AC-1860 has mature industrial applications in the following seven major fields:

  • Textile Dyeing Leveling Agent: Exhibits retarding and migration effects in high-temperature, high-pressure or room temperature dyeing processes, effectively reducing defects such as color spots and streaks, improving level dyeing on fabric surfaces, and serving as an important component in scouring and dyeing auxiliaries.
  • Industrial and Household Liquid Detergents: Has strong emulsifying and detergency against grease and oil stains, with moderate foam that is easy to rinse. Suitable for laundry detergents, kitchen and bathroom cleaners, etc.
  • Metalworking Fluids and Corrosion Inhibitors: Acts as an emulsifier and anti-rust component, improving lubrication and cooling performance of cutting fluids, forming a protective film on metal surfaces to inhibit corrosion.
  • Pesticide Emulsifier: Used for preparing emulsifiable concentrates (EC) or microemulsions (ME), enhancing the dispersion and spreadability of pesticide solutions, promoting wetting of plant leaves, and improving drug efficacy utilization.
  • Fiber Finishing Agents and Antistatic Agents: Reduces friction between fibers and metals, eliminates static electricity buildup during synthetic fiber processing, and improves smoothness in spinning, drawing, and other processes.
  • Leather Degreasing Agent: Provides gentle penetration and removal of natural oils from raw hides, leaving the leather soft and non-porous after degreasing.
  • Coating and Adhesive Systems: Used as an emulsifying and dispersing component for pigments and fillers in water-based systems, as well as a stabilizer in emulsion polymerization processes.

Precautions

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.
