USA - California Made Modification to the Proposed NSRL of Ethylene Oxide

​On April 7, 2023 OEHHA proposed to update the Proposition 65 no significant risk level for ethylene oxide in Cal. Code of Regs., Title 27, Section 25705(b)(1). OEHHA is now modifying the regulatory proposal by limiting the originally proposed update to the NSRL to the inhalation route and by proposing a separate NSRL for the oral route. The numerical values of the proposed NSRL are 0.058 micrograms per day for the inhalation route and 1.5 micrograms per day for the oral route.

Applications: Agricultural product fumigant, disinfectant (hospital equipment), thermobaric weapons; organic chemical synthesis (ethylene glycol and higher glycols), production of detergents, solvents, plastics, adhesives, antifreeze, pharmaceuticals; component of tobacco smoke.​

The public consultation is open until January 10, 2024.
