Butyl Benzyl Phthalate (BBP), Dibutyl Phthalate (DBP), Dicyclohexyl Phthalate (DCHP), Diethylhexyl Phthalate (DEHP), and Diisobutyl Phthalate (DIBP); Risk Evaluation under the Toxic Substances Control Act (TSCA); Notice of Availability
The Environmental Protection Agency (EPA or Agency) is announcing the availability of the final risk evaluations under the Toxic Substances Control Act (TSCA) for Butyl Benzyl Phthalate (BBP) (CARSN 85-68-7), Dibutyl Phthalate (DBP) (CASRN 84-74-2), Dicyclohexyl Phthalate (DCHP) (CASRN 84-61-7), Diethylhexyl Phthalate (DEHP) (CASRN 117-81-7), and Diisobutyl Phthalate (DIBP) (CASRN 84-69-5). The purpose of conducting risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment, without consideration of costs or non-risk factors, including unreasonable risk to potentially exposed or susceptible subpopulations identified as relevant to the risk evaluation by EPA, under the conditions of use. EPA used the best available science to prepare these final risk evaluations, and determined, based on the weight of scientific evidence, that BBP, DBP, DCHP, DEHP, and DIBP pose unreasonable risk to human health and/or the environment driven by specific conditions of use. Under TSCA, EPA must initiate risk management actions to address the unreasonable risk. 91 Federal Register (FR) 373, 6 January 2026: This notice of availability and the notice; request for comment notified as G/TBT/N/USA/2208 are identified by Docket Numbers EPA-HQ-OPPT-2018-0503 and EPA-HQ-OPPT-2018-0433.

The purpose of risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment under the conditions of use, including unreasonable risk to potentially exposed or susceptible subpopulations identified as relevant to the risk evaluation by EPA, and without consideration of costs or non-risk factors. EPA used the best available science to prepare this draft risk evaluation and to preliminarily determine, based on the weight of scientific evidence, that DBP and DEHP present unreasonable risk to health and the environment driven primarily by certain conditions of use analyzed in the draft evaluations.
