Analytically difficult to grasp
Di-(2-propylheptyl)phthalate (DPHP) is used as plasticizer, especially in polymers like PVC. Due to analytical difficulties within a total phthalate determination, DPHP is analysed with a specific method.
The Environmental Specimen Bank do not analyses the parent substance DPHP in human samples, but its main metabolites.
