Docosylbenzene is primarily used in the formulation of lubricants and greases due to its excellent thermal stability and low volatility. It serves as a high-performance base oil in industrial applications, particularly in environments requiring resistance to high temperatures and oxidation. Additionally, it is employed as a plasticizer in the production of polymers, enhancing flexibility and durability in materials such as PVC. In the cosmetics industry, it acts as an emollient and thickening agent in skincare products, providing a smooth texture and improved spreadability. Its chemical stability also makes it suitable for use in coatings and adhesives, where it contributes to long-lasting performance and resistance to degradation.
