Used primarily as a plasticizer in polymer formulations to improve flexibility and workability of plastics, especially in low-temperature applications. It is effective in polyvinyl chloride (PVC) and related polymers, enhancing durability and resistance to aging. Also serves as a lubricant base stock in specialty applications due to its good thermal stability and low volatility. Occasionally employed in cosmetic formulations as an emollient or solvent for fragrance ingredients, providing a non-greasy feel and improving product spreadability.
