EPA Requests Comments on Di-isodecyl Phthalate and Di-isononyl Phthalate Risks

On May 20, 2024, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register requesting comment on draft manufacturer-requested risk evaluation for Di-isodecyl Phthalate (DIDP) and the draft physical-chemical, fate, and hazard assessments for Di-isononyl Phthalate (DINP).

Both DIDP and DINP belong to a family of chemicals called phthalates and are primarily used as a plasticizer to increase flexibility in plastic coatings such as polyvinyl chloride (PVC).

EPA’s Science Advisory Committee on Chemicals (SACC) will consider and review the draft risk evaluation at a 4-day virtual peer review public meeting that will be held July 30-August 2, 2024. In addition, two virtual preparatory public meetings will be held on July 23, 2024, for the SACC to consider the scope and clarity of the draft charge questions for the peer review. Online registration for both meetings will be available in mid-June 2024.

Comments are due on the draft risk and hazard documents by July 19, 2024.
