Dodecylamine polyoxyethylene ether AC-1215 is a non-ionic surfactant produced by the addition polymerization of fatty amines with ethylene oxide. It can exhibit cationic behavior in acidic media after protonation of the amino group. According to GHS classification, this product belongs to Skin Irritation Category 2 (H315) and Serious Eye Irritation Category 2 (H319), and also has Long-term Hazard to the Aquatic Environment Category 3 (H412). This means that although the product is not highly toxic or corrosive, contact can cause significant skin and eye discomfort, and it poses a risk of long-term effects on aquatic ecosystems.
In practical use, the pH value (1% aqueous solution) of AC-1215 is 8-10, indicating mild alkalinity, which is one of the sources of its irritation. The flash point of the product is greater than 100°C, with no significant risk of combustion or explosion under normal operating conditions, but thermal decomposition may release toxic fumes containing nitrogen oxides and carbon monoxide. The acute toxicity of this product is low, with oral and dermal LD50 greater than 2000 mg/kg. Skin sensitization tests are negative, indicating it is not a sensitizer.
From an ecological safety perspective, the acute toxicity of AC-1215 to fish is 96h LC50 of 1–10 mg/L, placing it in the category of toxic to aquatic organisms. Fortunately, the product is readily biodegradable (BOD/COD ratio greater than 60% in 28 days) and has low bioaccumulation potential, so it is not persistent in the environment. Nevertheless, the product or wastewater containing the product must not be discharged directly into sewers, surface water, or groundwater systems; it must be disposed of in accordance with hazardous waste management regulations.

| First Aid for Ingestion | Rinse mouth with water. Do NOT induce vomiting (unless directed by medical personnel). Seek immediate medical attention. |
Personal Protective Equipment Requirements: Operators must wear certified chemical-resistant protective gloves (recommended nitrile or neoprene), splash-proof chemical goggles or face shield, and protective clothing. In situations with inadequate ventilation or where aerosols may form, wear a combined organic vapor/particulate respirator. Thoroughly wash hands and face after handling. Contaminated clothing must be thoroughly cleaned before reuse.
Operating Environment Requirements: Use in a well-ventilated area; local exhaust ventilation is recommended. Eyewash stations and emergency showers should be available in the workplace. Do not eat, drink, or smoke in the work area. Avoid formation of aerosols or mists. Operating temperatures should not be excessively high to prevent decomposition and generation of harmful gases. Use explosion-proof electrical/ventilation/lighting equipment.
Storage and Spill Handling: Store in a cool (recommended temperature 5-35°C), dry, well-ventilated warehouse. Keep containers tightly closed and away from heat sources, ignition sources, and direct sunlight. Avoid storage with strong oxidizing agents and strong acids. Recommended containers: stainless steel, polyethylene, or carbon steel with lining. Avoid reactive metals such as copper and aluminum. In case of spill, contain and absorb with inert absorbent material (sand, vermiculite, etc.), collect in sealed containers and dispose as hazardous waste. Prevent spills from entering soil, sewers, or waterways. Shelf life is 12 months under recommended storage conditions. Products beyond shelf life must be re-tested and approved before use.
