Used as a plasticizer in polymers to improve flexibility and durability, particularly in coatings, adhesives, and synthetic resins. Commonly applied in the formulation of inks and sealants due to its good solvency and low volatility. Also serves as a plasticizer in cellulose-based plastics, enhancing processability and mechanical properties. Its low toxicity and moderate evaporation rate make it suitable for use in some cosmetic and personal care products. Additionally, employed as a solvent and carrier in fragrance and flavor formulations.
