Hydrogenated Castor Oil Polyoxyethylene Ether HEL-40 (CAS No.: 61788-85-0) is a non-ionic surfactant produced by ethoxylation of natural hydrogenated castor oil. According to the United Nations GHS classification, this product is not classified as a dangerous substance or mixture and does not require statutory hazard labeling. Its acute oral toxicity (rat) LD50 > 5000 mg/kg, acute dermal toxicity (rabbit) LD50 > 2000 mg/kg, indicating an actual non-toxic level. It is not significantly irritating to the skin, has no known sensitizing effects, and may cause mild temporary irritation to the eyes.
During operation and use, it is recommended to maintain good ventilation in the work area and, if necessary, install local exhaust ventilation. Avoid generating dust during operation and use closed systems as much as possible. Operators should wear chemical safety goggles and protective gloves to avoid direct contact with eyes, skin, and clothing. After work, thoroughly wash hands and exposed skin with mild soap and clean water. Eating, drinking, and smoking are prohibited in the workplace. Work clothes should be stored separately from personal clothing.
In terms of formulation application, HEL-40 has good compatibility with various anionic, cationic, and amphoteric surfactants, but during storage, it should be kept away from strong acids, strong bases, and strong oxidizing agents. The product maintains stable performance under a wide pH range and high hardness water conditions, but it is recommended to verify the optimal dosage and compatibility scheme through small-scale tests during actual formulation development.

Skin contact: Immediately remove contaminated clothing and flush with plenty of running water and mild soap for at least 15 minutes. If irritation or discomfort occurs, seek medical attention.
Eye contact: Immediately lift the eyelids and flush thoroughly with plenty of running water or saline solution for at least 15 minutes, rolling the eyes to ensure thorough rinsing of the conjunctival sac. If symptoms such as persistent pain, tearing, or blurred vision occur, seek immediate medical attention.
Inhalation: Quickly move to fresh air and maintain an open airway. If breathing is difficult, administer oxygen. If symptoms persist, seek immediate medical attention.
Ingestion: Rinse mouth with water. Do NOT induce vomiting (unless instructed by medical personnel). Drink plenty of water to dilute. Seek immediate medical attention and present the product label.
Spill disposal: For small spills, cover with inert absorbent material (vermiculite, dry sand, or universal absorbent pad) and collect into a closed container. For large spills, dike to contain and prevent entry into sewers and waterways, transfer and recover with an explosion-proof pump. During cleanup, wear appropriate personal protective equipment and dispose of waste according to local regulations.
