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.
