⚗️EPA Draft Risk Evaluations for Phthalates and Business Implications
The Environmental Protection Agency (EPA or Agency) is announcing the availability of and seeking public comment on the draft risk evaluations under the Toxic Substances Control Act (TSCA) for Butyl Benzyl Phthalate (BBP) (CARSN 85-68-7) and Diisobutyl Phthalate (DIBP) (CASRN 84-69-5). 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 BBP and DIBP pose unreasonable risk to health and the environment driven primarily by certain conditions of use analyzed in the draft risk evaluations.

The Environmental Protection Agency (EPA or Agency) is announcing that there will be two virtual public meetings of the Science Advisory Committee on Chemicals (SACC). On July 21, 2025, a preparatory meeting for the SACC to consider the scope and clarity of the draft charge questions for the peer review; and on August 4 through 8, 2025, a peer review meeting for the SACC to consider the dibutyl phthalate (DBP), the dicyclohexyl phthalate (DCHP), and the di(2- ethylhexyl) phthalate (DEHP) draft risk evaluations, as well as the technical support documents for butyl benzyl phthalate (also known as benzyl butyl phthalate, BBP) and diisobutyl phthalate (DIBP), and public comments. The charge questions will address scientific and technical issues identified for peer review in all five phthalate risk evaluations scheduled to be finalized in 2025. EPA is also announcing the availability of and soliciting public comment on the draft documents and charge questions that will be provided to the SACC for this peer review. The draft risk evaluations and technical support documents were prepared under the Toxic Substances Control Act (TSCA) and will be submitted to the SACC for peer review.
