In mid-January, the U.S. Environmental Protection Agency (EPA) approved requests from two southern states (Georgia and Tennessee) asking for an emergency exemption that would allow them to aerosolize selected indoor spaces with an antiviral “air treatment” called Grignard Pure.

Grignard Pure is a nanoparticle-based product. Its active ingredient is a substance called triethylene glycol (TEG).

The EPA’s approval slid in under Section 18 of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), which allows the agency to green-light pesticides for unregistered uses in defined geographic areas for up to a year during public health emergencies deemed “urgent” and “non-routine.”

Grignard Pure contains TEG as a standalone chemical compound, but TEG is also a component of some polyethylene glycol (PEG) compounds (those of low molecular weight).
