Castor Oil Polyoxyethylene Ether EL-80 is a non-ionic surfactant with a flash point above 150°C (closed cup method). It is not classified as a flammable liquid but can still burn under high temperature conditions. Its acute toxicity to aquatic organisms is low (48-hour EC50 value for Daphnia magna > 100 mg/L), and the 28-day biodegradation rate can reach over 70%, making it an ultimately biodegradable substance. Although the overall risk level is low, improper handling may still cause irritation to the skin and eyes, so standardized operation is crucial.
The core safety principles for using this product include: maintain good ventilation in the operating area to avoid generating aerosols or sprays; keep away from strong oxidizing agents (such as peroxides, permanganates); prohibit eating, drinking, and smoking in the workplace; thoroughly wash hands and any exposed skin after operation. Contaminated work clothing must not be taken out of the workplace and should be washed before reuse.
| Protection Area | Requirements |
|---|---|
| Respiratory Protection | Generally not required. If oil mist is generated due to heating or stirring, it is recommended to wear a particulate mask with a filtration efficiency of at least 95% (e.g., P95 or FFP2 type). When oxygen levels are insufficient or the concentration of contaminants is unknown, use a supplied-air respirator. |
| Hand Protection | Wear tested chemical-resistant gloves, such as nitrile rubber gloves with thickness ≥ 0.11 mm. Avoid contaminating skin when removing gloves. |
| Eye Protection | Wear chemical safety goggles. If there is a risk of splashing, additionally use a face shield. |
| Body Protection | Wear impermeable chemical protective clothing to avoid direct skin contact. |
In case of exposure or accident, take the following first aid measures immediately:
Fire Response: Suitable extinguishing media include carbon dioxide, dry powder, alcohol-resistant foam, or water mist. Do NOT use direct water jet. Fire may produce carbon monoxide, carbon dioxide, and unburned hydrocarbons. Firefighters must wear self-contained positive pressure breathing apparatus and full chemical protective clothing.
Spill Handling: For small spills, absorb or wipe with inert absorbent material (e.g., sand, vermiculite) and collect in a sealable chemical waste container. For large spills, dike or pit for containment, cover with foam to reduce vapor release, and transfer to spare containers using explosion-proof pumps. Prevent entry into drains, surface water, or groundwater. The spill area may become extremely slippery; set up warning signs immediately.
Store the product in a cool (recommended temperature 5–35°C), dry, well-ventilated warehouse, keeping containers tightly closed. Keep away from strong oxidizing agents, strong acids, strong bases, and other incompatible substances. Avoid moisture and direct sunlight. This product is hygroscopic; reseal promptly after opening. The storage area should have spill-proof flooring and emergency spill containment facilities. Under unopened conditions, the shelf life is 24 months from the date of production.
