Dicyclohexyl phthalate (DCHP); Draft Risk Evaluation Under the Toxic Substances Control Act (TSCA); Notice of Availability and Request for Comment
Published Date: 1/7/2025
Notice
Summary
The EPA has checked out a chemical called Dicyclohexyl phthalate (DCHP) and found it might be risky for people’s health. They want companies and the public to share their thoughts by March 10, 2025. If you make, use, or handle DCHP, this could mean new rules and safety steps soon, so keep an eye on updates!
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Possible Rules: Labels, Records, Limits, or Bans
If EPA finalizes an unreasonable risk finding for DCHP, the chemical must move to TSCA risk management and EPA could require labeling, recordkeeping, actions to reduce human exposure or environmental release, or ban the chemical or certain uses. If you make or use DCHP in business, these regulatory options could change what you must do or what uses are allowed.
EPA: DCHP May Pose Human Health Risk
EPA's draft risk evaluation preliminarily finds that Dicyclohexyl phthalate (DCHP, CASRN 84-61-7) poses an unreasonable risk to human health. If you make, process, distribute, use, or handle DCHP in products like adhesives, plastics, rubber, or resins, this finding could lead to future regulatory actions.
Worker Exposures Raise Specific Concerns
EPA evaluated 24 conditions of use (COUs) for DCHP and found that 9 of those 24 COUs have risk estimates that raise concerns for workers' exposure. If you are a worker exposed to DCHP on the job, EPA's draft says those workplace uses are where health concerns were identified.
Consumers and Public Not Identified At Risk
EPA's draft risk evaluation found no conditions of use that raise the same health concerns for consumers or the general population. This draft says the risk estimates that raised concerns were specific to certain worker uses, not to consumers or the general public.
