Hydrogenated castor oil polyoxyethylene ether HEL-40 (CAS No.: 61788-85-0) is not classified as a hazardous substance or mixture according to the UN GHS classification criteria and does not require mandatory hazard labeling. The product has an acute oral toxicity (rat) LD50 greater than 5000 mg/kg and an acute dermal toxicity (rabbit) LD50 greater than 2000 mg/kg, making it practically non-toxic. It does not cause significant skin irritation, but prolonged or repeated contact may lead to mild defatting and dryness, and it may cause slight temporary eye irritation.
Despite its overall good safety profile, standard chemical management practices should be followed during routine handling. Work areas should be well-ventilated, and direct contact with eyes, skin, and clothing should be avoided. It is recommended to wear chemical safety goggles and protective gloves. After operation, wash hands and exposed skin thoroughly with mild soap and water. Eating, drinking, and smoking are prohibited in the workplace. Operators should receive training on safe chemical handling and understand the product properties and corresponding protective measures.
For storage, keep the product in its original tightly closed container in a cool, dry, and well-ventilated area, away from direct sunlight. The recommended storage temperature is between 5°C and 35°C to prevent freezing or thermal degradation. Keep away from heat sources, ignition sources, and strong oxidizers, and avoid storing with incompatible substances such as strong acids and strong bases. Thermal decomposition may release irritating fumes; avoid inhalation.

This product is biodegradable, meeting relevant OECD standards, and does not have significant bioaccumulation potential. At recommended usage concentrations, the risk to the aquatic environment is low. However, care should be taken to prevent large quantities of undiluted or untreated product from entering waterways, soil, or public drainage systems. Waste disposal must comply with national and local environmental regulations. In case of a spill, small spills should be collected with inert absorbent materials (e.g., vermiculite, dry sand, or universal absorbent pads) and placed in closed containers; for large spills, isolate the area, build dikes to contain the spill, and prevent it from entering drains or soil.
