Chemicals Listed Effective March 19, 2021 As Known to The State Of California to Cause Cancer: Molybdenum Trioxide and Indium Tin Oxide
Effective March 19, 2021, the Office of Environmental Health Hazard Assessment (OEHHA) is adding molybdenum trioxide (CAS No. 1313-27-5) and indium tin oxide (CAS No. 50926-11-9) to the list of chemicals known to the State of California to cause cancer for purposes of Proposition 65. The listing of these chemicals is pursuant to the “Labor Code” listing mechanism.
The basis for the listings was described in a public notice published in the October 9, 2020, issue of the California Regulatory Notice Register (Register 2020, No. 41-Z). The title of the notice was “Notice of Intent to List Chemicals by the Labor Code Mechanism: Molybdenum Trioxide and Indium Tin Oxide.” The publication of the notice initiated a 45-day public comment period. We received one comment on molybdenum trioxide. The comment and OEHHA’s response are posted with the Notice of Intent to List.
A complete, updated Proposition 65 chemical list is available on the OEHHA website.
