The functional groups in the substructure of castor oil determine that it can undergo a variety of chemical reactions and generate many derivative products, most of which are important fine chemicals. Ethoxylated hydrogenated castor oil is one of the derivative products of castor oil, which has stable performance and high melting point and is widely used in cosmetics. The reaction product with hydrogen oxide file is file base lubricating oil, which is widely used in aviation industry, automobile manufacturing and machining industries, and has a large demand in domestic and foreign markets. In addition, Ethoxylated hydrogenated castor oil can be used as a base material for various chemical reactions or unit processing processes, which is easy to crack, unitarization, phthalamination, sulfonation, halogenation, saponification, hydrolysis, epoxidation and ethoxylation and other chemical reactions, and the derived products have a wide range of applications.

Ethoxylated hydrogenated castor oil plays the role of thickening, hardening and slow release in preparations, so it is used as thickening agent, hardening agent and slow release agent for the preparation of semi-solid preparations and solid preparations, such as ointment, suppository, pill, tablet and so on. It is mainly used as a paste hardener in ointments, creams and suppositories to adjust the consistency of preparations; In oral preparations, it is mainly used for the preparation of sustained release tablets and capsules, which can be used as a coating film or form a solid skeleton, and play the role of sustained release or controlled release; It can also be used as a lubricant for tablets and capsules to improve the fluidity of particles.
