C.I. Disperse Yellow 3 and 2,6-dimethyl-N-nitrosomorpholine (DMNM) Listed Effective February 8, 2013 as Known to the State of California to Cause Cancer

Effective February 8, 2013, the Office of Environmental Health Hazard Assessment (OEHHA) is adding C.I. Disperse Yellow 3 (CAS No. 2832-40-8) and 2,6-dimethyl-N-nitrosomorpholine (DMNM) (CAS No. 1456-28-6) to the list of chemicals known to the State to cause cancer for purposes of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65¹).

C.I. Disperse Yellow 3 and 2,6-dimethyl-N-nitrosomorpholine (DMNM) were considered by the Carcinogen Identification Committee (CIC) in its official capacity as the “state’s qualified experts” at a public meeting held on January 25, 2013.  The CIC determined that the two chemicals were clearly shown, through scientifically valid testing according to generally accepted principles, to cause cancer.  Regulations governing the criteria for listing of chemicals by the CIC are set out in Title 27, California Code of Regulations, section 25305(a)(1). 

A complete, updated chemical list is published in this issue of the California Regulatory Notice Register and is available on the OEHHA website.

In summary, the following chemicals are being listed under Proposition 65 as known to the State to cause cancer:
