Used primarily as a plasticizer in polymers to improve flexibility and workability, especially in PVC and other vinyl resins. It enhances low-temperature performance and increases durability in coatings, adhesives, and sealants. Also functions as a lubricant base stock or additive in specialty formulations due to its good thermal stability and low volatility. Found in some cosmetic and personal care products as an emollient or skin-conditioning agent. Its hydrophobic nature makes it useful in water-resistant applications and in the formulation of soft touch coatings.
