Used primarily as a plasticizer in polymer formulations to improve flexibility and workability of plastics, especially in polyvinyl chloride (PVC) and related materials. It enhances low-temperature performance and increases resistance to aging and cracking. Also employed in lubricant formulations for its good viscosity-temperature properties and biodegradability. Finds use in cosmetic and personal care products as an emollient and skin-conditioning agent due to its smooth texture and stability. Additionally, serves as a solvent or carrier in pesticide formulations, improving dispersion and penetration of active ingredients. Its ester structure contributes to ready hydrolysis in the environment, making it suitable for applications where environmental impact is a concern.
