Arachidic acid is primarily used in the production of lubricants, waxes, and plastics due to its long hydrocarbon chain, which provides stability and water resistance. It is also employed in the formulation of cosmetics and personal care products, where it acts as an emollient and thickening agent, enhancing texture and consistency. In the food industry, it serves as a food additive, contributing to the texture and shelf life of certain products. Additionally, arachidic acid is utilized in the synthesis of surfactants and detergents, where it helps in reducing surface tension and improving cleaning efficiency. Its applications extend to the pharmaceutical industry, where it is used in the production of certain drugs and as a component in controlled-release formulations.
