Ricinoleic acid is primarily used in the production of surfactants and soaps due to its ability to act as an emulsifying agent, helping to mix oil and water. It is also a key ingredient in the manufacturing of lubricants and greases, where its unique properties enhance viscosity and stability. In the pharmaceutical industry, it serves as a precursor for the synthesis of various compounds, including those with anti-inflammatory and analgesic properties. Additionally, ricinoleic acid is utilized in the cosmetics industry, where it is valued for its moisturizing and skin-conditioning effects. Its application extends to the production of biodiesel, where it acts as a renewable raw material. In agriculture, it is sometimes used as a component in biopesticides due to its natural origin and effectiveness.
