Effective October 28, 2011, the Office of Environmental Health Hazard Assessment (OEHHA) is adding tris(1,3-dichloro-2-propyl) phosphate (TDCPP) (CAS No. 13674-87-8) 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 65).
Tris(1,3-dichloro-2-propyl) phosphate (TDCPP) was considered by the Carcinogen Identification Committee (CIC) in its official capacity as the “state’s qualified experts” at a public meeting held on October 12, 2011. The CIC determined that tris(1,3-dichloro-2-propyl) phosphate (TDCPP) was clearly shown, through scientifically valid testing according to generally accepted principles, to cause cancer.
