EPA Probes Weirdly Named Chemicals Sneaking into Daily Products Safety

## Summary

The EPA is holding two virtual meetings in May and June 2026 to review safety reports on four chemicals used in everyday products. They want scientists and the public to check their work and share thoughts before final decisions. If you’re involved in manufacturing, health, or environmental safety, these meetings and comments could affect future rules and costs.

## Abstract

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 May 26, 2026, a preparatory meeting will be held for the SACC to consider the scope and clarity of the draft charge questions for the peer review of the draft risk evaluations for 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8- hexamethylcyclopenta [g ]-2-benzopyran (HHCB) and phthalic anhydride and the draft hazard assessments for o-dichlorobenzene (o-DCB) and p- dichlorobenzene (p-DCB). The peer review meeting will be held June 8 through 12, 2026, for the SACC to consider the draft risk evaluations for HHCB and phthalic anhydride, the draft hazard assessments for o-DCB and p-DCB, the technical support documents, and their public comments. 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 draft hazard assessments were prepared under the Toxic Substances Control Act (TSCA) and will be submitted to the SACC for peer review.
