Notice to Interested Parties Chemicals Listed Effective December 17, 2021 As Known to the State of California to Cause Cancer: Tetrahydrofuran; 2-ethylhexyl Acrylate; Methyl Acrylate; and Trimethylolpropane Triacrylate, Technical Grade

Effective December 17, 2021, the Office of Environmental Health Hazard Assessment (OEHHA) is adding tetrahydrofuran (CAS No. 109-99-9), 2-ethylhexyl acrylate (CAS No. 103-11-7), methyl acrylate (CAS No. 96-33-3), and trimethylolpropane triacrylate, technical grade to the list of chemicals known to the State of California to cause cancer for purposes of Proposition 65[1]. The listing of these chemicals is pursuant to the “Labor Code” listing mechanism[2].

The basis for the listings was described in a public notice published in the June 11, 2021, issue of the California Regulatory Notice Register (Register 2021, No. 24-Z). The title of the notice was “Notice of Intent to List Chemicals by the Labor Code Mechanism: Tetrahydrofuran; 2-Ethylhexyl Acrylate; Methyl Acrylate; and Trimethylolpropane Triacrylate, Technical Grade.” The publication of the notice initiated a 45-day public comment period[3].  We received five sets of comments during the comment period. The comments and OEHHA’s responses are posted with the Notice of Intent to List.

A complete, updated Proposition 65 chemical list is available on the OEHHA website.
