Lignoceric acid is primarily used in the production of cosmetics and personal care products. It acts as an emollient, helping to soften and smooth the skin by forming a protective barrier that retains moisture. This makes it a valuable ingredient in lotions, creams, and moisturizers designed for dry or sensitive skin.

In the pharmaceutical industry, it is utilized as a component in drug delivery systems. Its properties aid in the stabilization of formulations and enhance the absorption of active ingredients through the skin.

Additionally, lignoceric acid is employed in the manufacturing of surfactants and detergents. Its long carbon chain contributes to the effectiveness of these products in breaking down oils and greases, making it useful in cleaning agents and industrial applications.

In research, it serves as a standard or reference compound in lipid studies, particularly in the analysis of fatty acids and their role in biological systems. Its presence is also studied in relation to certain metabolic disorders, providing insights into lipid metabolism and associated diseases.
