Background

OEHHA is the lead agency for implementation of Proposition 65. The CIC advises and assists OEHHA in compiling the list of chemicals known to the state to cause cancer within the meaning of the Act, as required by Proposition 65 (Health and Safety Code section 25249.8.). The CIC serves as the state’s qualified experts for determining whether a chemical has been clearly shown through scientifically valid testing according to generally accepted principles to cause cancer within the meaning of the Act (Health and Safety Code section 25249.8.). 

A request for relevant information on the potential carcinogenicity of this chemical opened on November 29, 2024, and closed on January 10, 2025. No submissions were received.
