Diisononyl phthalate (DINP) is an orally active polyvinyl chloride plasticizer and indirect food additive. Diisononyl phthalate activates the ACE/AT1R axis and inhibits the production of NO. Diisononyl phthalate reduces the expression of eNOS. Diisononyl phthalate induces increased blood pressure in mice. Diisononyl phthalate induces monocytic leukemia in rats. Diisononyl phthalate can be used in hypertension-related research[1][2].
