Used primarily as a plasticizer in polymers to enhance flexibility and durability, especially in polyvinyl chloride (PVC) applications. It improves low-temperature performance and resistance to water extraction, making it suitable for use in cables, flooring, and coated fabrics. Also found in some cosmetic formulations as an emollient due to its skin-conditioning properties. Its low volatility and good solubility characteristics support its use in adhesives and sealants as a performance additive.
