Castor oil is a pale yellow viscous non-drying oil that is soluble in most organic solvents except fatty acid hydrocarbons. It is particularly characterized by its solubility in alcohol. It exhibits good compatibility with nitrocellulose, ethyl cellulose, cellulose acetate butyrate, polyamide, butylated melamine (or urea) formaldehyde resins, rosin, shellac, and can be used as a plasticizer. Additionally, it shows relatively good compatibility with polyvinyl butyral, polyvinyl chloride-polyvinyl acetate-vinyl alcohol copolymers, and chlorinated rubber.

With its excellent stability, color retention, flexibility, pigment dispersibility, wettability, lubricity, low-temperature properties, electrical characteristics, and biological properties, it can be incorporated into varnish coatings, artificial leather, inks, sealants, lubricants, stationery, cosmetics, electrical insulating materials, pharmaceuticals, and more.

Castor oil can undergo various chemical reactions through its hydroxyl groups, double bonds, and ester bonds. The resulting derivatives are widely used in the coatings industry, plastics industry, rubber industry, building materials industry, metal industry, and machinery industry.
