This rulemaking will address the unreasonable risk of injury to health presented by diisodecyl phthalate (DIDP). Section 6(a) of the Toxic Substances Control Act (TSCA) requires that EPA, when it determines in a TSCA risk evaluation that a chemical presents an unreasonable risk of injury to health or the environment, apply one or more requirements under TSCA section 6(a) by rule to the extent necessary so the chemical substance no longer presents an unreasonable risk. EPA’s final risk evaluation for DIDP, describing DINP's conditions of use and presenting EPA's determination of unreasonable risk, is in docket EPA-HQ-OPPT-2018-0435, with additional information, including the draft risk evaluation and public comments received, in docket EPA-HQ-OPPT-2024-0073.
