Fatty amine polyoxyethylene ether AC-1860 is a low-toxicity substance, but it is moderately irritating to the skin and eyes, and it is toxic to aquatic organisms with potential long-term environmental effects. Standard operating procedures must be followed, and it must be prevented from entering water bodies.
Detailed Explanation
Fatty amine polyoxyethylene ether AC-1860 (CAS: 26635-92-7) is classified as a low-toxicity substance in toxicology. Acute oral toxicity tests (rats) show an LD50 > 2000 mg/kg, and acute dermal toxicity tests (rabbits) also show an LD50 > 2000 mg/kg, indicating a low acute toxicity risk from single high-level exposure. However, it is moderately irritating to the skin and eyes (GHS Category 2), with direct contact potentially causing skin redness, pain, and discomfort, and eye contact potentially causing severe irritation and damage.
Environmentally, this product poses a clear hazard to aquatic ecosystems. The acute fish toxicity test LC50 (96 hours) is 1–10 mg/L, classifying it as toxic to aquatic organisms. The GHS classification assigns it to "Hazardous to the aquatic environment – Acute hazard category 2 (H401)" and "Hazardous to the aquatic environment – Chronic hazard category 3 (H412)", meaning even low concentrations may have toxic effects on fish and aquatic invertebrates, with long-term persistent impacts and slow degradation in the natural environment.
Therefore, while the acute toxicity risk to humans from compliant use of this product is manageable, direct contact with skin and eyes must be strictly avoided, and large discharges into surface water, groundwater, and soil must be prevented. During use, wear chemical safety goggles, chemical-resistant gloves (butyl rubber or nitrile rubber), and other protective equipment. Ensure good ventilation in the work area.

Application Recommendations
- Industrial use: In industrial applications such as textile printing and dyeing, metalworking, and pesticide formulations, establish closed or semi-closed operating systems, equipped with local exhaust ventilation to reduce personnel exposure through engineering controls.
- Formulation design: When compounding in end products such as household detergents, control the concentration of this component in the final product to ensure that the risks from skin contact and accidental ingestion are within acceptable limits.
- Wastewater treatment: Industrial wastewater containing this product must undergo biochemical or chemical treatment (e.g., flocculation, oxidative degradation) before discharge, and must not be directly discharged into municipal sewer systems or natural water bodies.
Precautions
- Operators must be professionally trained and familiar with the GHS hazard classification and protective measures for this product.
- Always wear chemical safety goggles and chemical-resistant gloves during operation; if necessary, wear a face shield or respiratory protection.
- In case of skin contact, immediately rinse with plenty of running water and soap for at least 15 minutes; in case of eye contact, open eyelids and rinse with water or saline for at least 15 minutes, then seek immediate medical attention.
- Collect spills using inert absorbent materials (sand, vermiculite), place in a sealed container, and dispose of as hazardous waste in accordance with regulations. Do not flush into drains.
- Store at 10°C–35°C in a cool, dry, well-ventilated area, away from strong oxidizers and strong acids. Keep containers tightly closed.
- Disposal must be carried out by qualified professional agencies, with recommended chemical treatment or high-temperature incineration to prevent the generation of harmful gases such as nitrogen oxides.
