Ricinoleic acid is widely used in the production of biodiesel due to its high viscosity and stability. It serves as a key raw material in the manufacturing of lubricants, offering excellent performance in high-temperature and high-pressure environments. In the cosmetics industry, it is utilized as an emulsifying agent and moisturizer, enhancing the texture and hydration of skincare and haircare products. Additionally, it is employed in the synthesis of surfactants and detergents, improving their cleaning efficiency. The acid also finds applications in the pharmaceutical sector, where it is used as a precursor for certain drugs, an anti-inflammatory agent, and an aid in drug absorption. Its versatility extends to the production of plastics, bioplastics, and coatings, where it acts as a plasticizer and improves material flexibility while reducing environmental impact. In the food industry, it is used as an additive to enhance emulsion stability and product properties.
