Ricinoleic acid polyoxyethylene ether is primarily used as an agricultural emulsifier, textile fiber oiling agent, and oil field crude oil dehydration agent. In the textile industry, it serves as a fiber oiling agent; in the woolen textile industry, it is used as wool oil and antistatic spinning oil for vinylon. It can also be used for emulsifying fats and waxes, oleic acid, and mineral oils. In biochemical research, it is employed for emulsifying and dissolving oil and other water-insoluble substances. As a non-ionic solvent, it is used as a solvent and emulsifier for water-insoluble materials or other liposoluble materials in semi-solid and liquid formulations.
