Chemical Listed Effective May 2, 2014 as Known to the State of California to Cause Cancer: N,N-Dimethyl-p-Toluidine

Effective May 2, 2014, the Office of Environmental Health Hazard Assessment (OEHHA) is adding N,N-dimethyl-p-toluidine to the list of chemicals known to the State to cause cancer for purposes of Proposition 651.

The listing of N,N-dimethyl-p-toluidine is based on formal identification by the National Toxicology Program (NTP), an authoritative body2, 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 N,N-dimethyl-p-toluidine is included in the Notice of Intent to List posted on OEHHA’s website and published in the March 14, 2014 issue of the California Regulatory Notice Register (Register 2014, No. 11-Z).  OEHHA received one public comment on the Notice of Intent to List that was informational in nature and did not require a response.  The comment is posted with the Notice of Intent to List.

A complete, updated chemical list will be published elsewhere in this issue of the California Regulatory Notice Register and is available on the OEHHA website.  In summary, N,N-dimethyl-p-toluidine is being listed under Proposition 65 as known to the State to cause cancer, as follows:
