Dibenzyl phthalate, classified as a diaryl phthalate, plays a role as a plasticizer in enhancing the characteristics of synthetic resin substrates. By incorporating this compound, the flexibility and durability of the final products are significantly improved. In addition to its plasticizing properties, dibenzyl phthalate acts as an endocrine disrupting chemical, capable of interfering with various cell signaling pathways.
