Used primarily as a plasticizer in plastics and resins to improve flexibility and durability, especially in cellulose-based materials like coatings and films. Commonly found in adhesives, printing inks, and synthetic rubber to enhance workability and elasticity. Also employed as a solvent or carrier in perfumes and cosmetics due to its low volatility and mild odor. Occasionally used in lubricants and cold-welding compounds for improved performance.
