Octadecyl polyoxyethylene ether AC-1812 (CAS number: 26635-75-6) is a nonionic surfactant that exhibits cationic properties under acidic conditions. It appears as a light yellow to yellow paste or viscous liquid. Although this product is managed as a general chemical and is not classified as a flammable solid, it can melt and decompose at high temperatures, producing irritating or toxic fumes. Therefore, safety operating procedures must be strictly followed during use.
Operators must undergo specialized training and be familiar with the product characteristics and operating procedures before starting work. The workplace should maintain good ventilation to avoid dust accumulation. During operation, handle with care to prevent container breakage or dust generation, and use non-sparking tools. Eating, drinking, and smoking are strictly prohibited in the work area. After work, thoroughly wash hands and exposed skin. Additionally, avoid contact of the product with strong oxidizers, strong acids, and strong bases to prevent violent reactions.
For personal protection, it is recommended that operators wear approved dust masks, chemical safety goggles, and chemical-resistant gloves, as well as long-sleeved protective clothing to minimize exposure risks.

Skin Contact: Immediately remove contaminated clothing and rinse thoroughly with plenty of soap and running water for at least 15 minutes. If irritation or redness occurs, seek medical attention immediately.
Eye Contact: Immediately flush eyes with an eyewash station or plenty of running water for at least 15 minutes, lifting eyelids. Do not apply any ointment; seek immediate ophthalmological medical attention.
Inhalation: Quickly move the affected person to fresh air and maintain an open airway. If breathing is difficult, trained personnel should administer oxygen. If breathing or heartbeat stops, immediately perform CPR and call for emergency medical assistance.
Ingestion: Immediately rinse mouth with plenty of water, drink sufficient warm water (about 300-500 ml), and induce vomiting cautiously under medical guidance. Do not induce vomiting in unconscious persons; seek medical attention as soon as possible and present this safety data sheet.
Spill Handling: Quickly evacuate non-emergency personnel, isolate the spill area, and set up warning signs. Handling personnel must wear appropriate protective equipment, carefully sweep up using non-sparking tools or vacuum, and place into dry, clean, covered containers. Collected spill material should be disposed of as chemical waste by qualified agencies, preventing entry into drains or waterways.
This product is not classified as a flammable solid, but it can melt and decompose at high temperatures, producing irritating or toxic fumes. Suitable extinguishing media: Water spray, alcohol-resistant foam, dry powder, carbon dioxide. Firefighters must wear positive-pressure self-contained breathing apparatus and full protective gear. Based on fire conditions, move unexposed containers away from the fire area or continuously cool exposed containers with water spray.
