Used primarily as a plasticizer in polymers to enhance flexibility and durability, especially in polyvinyl chloride (PVC) products such as wires, pipes, and coatings. It improves workability and elongation properties in adhesives and sealants. Also used in some personal care products, like perfumes and lipsticks, to stabilize fragrances, improve solubility, and aid in pigment dispersion. Due to potential endocrine-disrupting effects and environmental concerns, its use is restricted in certain consumer products, especially those for children, in various countries.
