Castor oil polyoxyethylene ether EL-60 is a non-hazardous substance with extremely low toxicity and no irritation. However, standard chemical safety protocols must still be followed during operation, including personal protection and proper storage.
Detailed Description
Castor oil polyoxyethylene ether EL-60 (PEG-60 castor oil) has undergone authoritative toxicological testing and is classified as a practically non-toxic product. Its acute oral toxicity LD₅₀ is greater than 5000 mg/kg, and it shows no irritation to skin or eyes (verified by OECD 404 and OECD 405 tests). Skin sensitization test results are negative (OECD 406), and the Ames mutagenicity test is also negative, demonstrating excellent safety.
Although the product is inherently safe, as a chemical product, operators should still receive professional training and strictly follow operating procedures. It is recommended to work in well-ventilated areas, wear chemical safety goggles, protective clothing, and chemical-resistant gloves, and avoid direct contact with eyes, skin, and clothing. Eating, drinking, or smoking is prohibited during operation. After work, promptly wash hands and exposed skin, and change contaminated clothing.
In terms of environmental safety, this product is readily biodegradable (BOD/COD > 60% in OECD 301B test), with a fish 96-hour LC₅₀ greater than 100 mg/L, indicating minimal impact on the ecological environment. However, in case of leakage, it must be promptly collected and treated to prevent entry into sewers, surface water, or soil. Use inert absorbent materials (such as sand, vermiculite) to collect and dispose of as chemical waste in accordance with local regulations.

Storage Requirements
- Store in a dedicated warehouse that is cool, dry, and well-ventilated, keeping containers tightly closed.
- Keep away from heat sources, ignition sources, and incompatible substances such as strong oxidizers.
- Avoid direct sunlight. The ambient temperature should not exceed 40°C. Prevent drastic temperature fluctuations.
- Use rust-proof, corrosion-resistant storage containers and ensure labels are clear and intact.
- Implement the "first-in, first-out" principle. Do not store together with food, beverages, or animal feed.
- The storage area should be equipped with spill containment materials and have emergency eyewash and safety shower equipment.
Emergency Response Points
First Aid Measures
- Inhalation: Move the affected person to fresh air immediately. If discomfort occurs, seek medical attention.
- Skin contact: Remove contaminated clothing. Rinse thoroughly with plenty of water and soap. If redness or irritation occurs, seek medical help.
- Eye contact: Immediately lift eyelids and flush continuously with plenty of running water or saline solution for at least 15 minutes. If irritation or pain persists, seek medical attention immediately.
- Ingestion: Do NOT induce vomiting. Rinse mouth with water. Seek medical attention immediately or contact a poison control center.
Firefighting Measures
- Suitable extinguishing media: water spray, alcohol-resistant foam, dry powder, or carbon dioxide.
- During a fire, smoke may contain carbon monoxide, carbon dioxide, etc. Firefighters should wear self-contained breathing apparatus and full protective equipment.
- Use water spray to cool containers exposed to fire to prevent rupture. Collect firefighting water runoff to avoid environmental contamination.
Leak/Spill Handling
- Evacuate personnel to safe areas. Isolate the spill area. Eliminate all ignition sources.
- Small spills: Cover with inert absorbent material (e.g., sand, vermiculite) and collect into dedicated containers.
- Large spills: Contain by diking or damming to prevent entry into sewers, surface water, or soil. Transfer to hazardous waste containers for professional disposal.
- Cleaning equipment should be explosion-proof and static-discharge protected to avoid generating dust or oil mist.
