On June 28, 2019, the Office of Environmental Health Hazard Assessment (OEHHA) added 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.
The listing of p-chloro-α,α,α-trifluorotoluene is based on formal identification by the National Toxicology Program (NTP) 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).
Detailed information of the newly added substance is shown as below:
|Chemical||CAS No.||Endpoint||Listing Mechanism*|
|p-chloro-α,α,α-trifluorotoluene (para-Chlorobenzotrifluoride, PCBTF)||—||Cancer||AB (NTP)|
*Listing mechanism: AB – “authoritative bodies” mechanism (Title 27, Cal. Code of Regs. section 25306).
