Chemical Listed Effective June 28, 2019 as Known to the State Of California To Cause Cancer: P-Chloro-a,a,a-Trifluorotoluene (Para-Chlorobenzotrifluoride, PCBTF)
Effective June 28, 2019, the Office of Environmental Health Hazard Assessment (OEHHA) is adding p-chloro-α,α,α-trifluorotoluene (para-Chlorobenzotrifluoride, PCBTF) to the list of chemicals known to the State of California to cause cancer for purposes of Proposition 65[1].
The listing of p-chloro-α,α,α-trifluorotoluene is based on formal identification by the National Toxicology Program (NTP), an authoritative body[2], that the chemical causes cancer. The criteria used by OEHHA for the listing of chemicals under the “authoritative bodies” mechanism can be found in Title 27, Cal. Code of Regs., section 25306.
The documentation supporting OEHHA’s determination that the criteria for administrative listing have been satisfied for p-chloro-α,α,α-trifluorotoluene is included in the “Notice of Intent to List: p-Chloro-α,α,α-trifluorotoluene (para-Chlorobenzotrifluoride, PCBTF)” posted on OEHHA’s website and published in the November 23, 2018 issue of the California Regulatory Notice Register (Register 2018, No. 47-Z). The publication of the notice initiated a public comment period that closed on January 23, 2019. OEHHA received one public comment. The comment and OEHHA’s response is posted with the Notice of Intent to List.
A complete, updated Proposition 65 chemical list is available on the OEHHA website at.
