Arachidic acid is primarily used in the production of lubricants, waxes, and plastics due to its long-chain fatty acid structure, which provides stability and durability. It is also employed in the formulation of cosmetics and personal care products, where it acts as an emollient and thickener, enhancing texture and skin conditioning. In the food industry, it serves as a food additive, contributing to the consistency and shelf life of certain products. Additionally, arachidic acid is utilized in the synthesis of surfactants and detergents, where its properties help in reducing surface tension and improving cleaning efficiency. Its applications extend to the pharmaceutical sector, where it is used in the preparation of controlled-release drug formulations.
