Fatty amine polyoxyethylene ether AC-1860 (CAS No.: 26635-92-7) is a high-performance nonionic surfactant that exhibits cationic characteristics in acidic media. Under normal conditions, this product is chemically stable, resistant to acids, alkalis, and hard water, and not easily hydrolyzed. However, improper handling may still cause harm to human health and aquatic ecosystems. Therefore, it is necessary to fully understand its hazardous properties and take corresponding protective measures before use.
According to GHS classification, AC-1860 falls under skin corrosion/irritation Category 2 (H315), serious eye damage/eye irritation Category 2 (H319), and is acutely and chronically toxic to aquatic life (H401, H412). Although its acute oral and dermal toxicity are both low (LD50 > 2000 mg/kg), direct contact can still cause skin redness, pain, and eye discomfort. Long-term or repeated exposure may exacerbate irritation reactions.
When handling AC-1860, the work area should have good ventilation, and the airborne concentration should be kept below occupational exposure limits. Operators must receive professional training and wear the following personal protective equipment:
After operation, thoroughly wash face and hands. Contaminated clothing must be washed before reuse. Eating, drinking, or smoking is strictly prohibited in the workplace. Avoid direct contact with skin, eyes, and clothing.
This product should be stored in a cool, dry, well-ventilated dedicated warehouse. The recommended storage temperature range is 10°C–35°C. Avoid freezing and prolonged high-temperature exposure. Keep containers tightly closed to prevent moisture and foreign matter ingress. It should be stored separately from strong oxidizers and strong acids. The packaging container material should be stainless steel, polyethylene, or plastic-lined iron drums. Avoid using metal containers such as copper or aluminum.
In case of spillage, evacuate non-essential personnel and isolate the spill area. Small spills can be absorbed with inert absorbent materials such as sand or vermiculite and collected in closed containers. For large spills, build dikes and transfer the liquid to emergency containers using explosion-proof pumps. Prevent the spill from entering sewers, surface water, and groundwater to avoid harm to aquatic environments (fish 96h LC50 is 1–10 mg/L).
| Route of Exposure | Emergency Treatment Methods |
|---|---|
| Skin Contact | Immediately remove contaminated clothing and thoroughly flush with plenty of running water and soap for at least 15 minutes. If irritation persists, seek medical attention. |
| Eye Contact | Immediately open eyelids and flush thoroughly with plenty of running water or saline for at least 15 minutes, while rotating the eyeballs. Seek medical attention immediately. |
| Inhalation | Quickly move the patient to fresh air and maintain an open airway. If breathing is difficult, administer oxygen and seek medical attention. |
| Ingestion | Rinse mouth with water; do NOT induce vomiting. Seek medical attention immediately and present the safety data sheet or container label of this product. |
AC-1860 is toxic to aquatic life with long-lasting effects. Do not discharge this product directly into water bodies or the environment. Waste should be disposed of by qualified professional organizations using methods such as chemical treatment or high-temperature incineration, while preventing the generation of harmful gases such as nitrogen oxides. If packaging containers are to be recycled, they must be thoroughly cleaned to remove residues. Non-recyclable containers should be disposed of as hazardous waste. Rinse water after use should also be collected and treated, and must not be discharged arbitrarily.
