Used primarily as a plasticizer in polymers, especially in PVC, to improve flexibility and workability at low temperatures. It is valued for its good low-temperature performance and resistance to extraction by water or oils. Commonly found in cables, hoses, films, and coated fabrics. Also serves as a lubricant or emollient in cosmetic formulations due to its smooth texture and stability. Its low volatility makes it suitable for applications requiring prolonged thermal exposure.
