I don't know anything about it, really. I saw this online and share with the group with hopes that you would talk about it. Their website is really vague with the exception of saying that it has been used for a long time in the entertainment industry. Hence my hope that Monona would chime in, as she did 😊

Of course not. It's triethylene glycol. Look up the structure. I'm just glad they require posting about causing irritation in sensitive people since we have been dealing with complaints and health effects in the theatrical biz for decades with this fog. FDA has listed propylene glycol and glycerin as respiratory toxicants and diethylene glycol as poisonous based on their studies of vaping chemicals. But I don't think EPA and FDA talk much.  Monona

The EPA provided specifics in a recent news release:


"Triethylene glycol (TEG) is the active ingredient in Grignard Pure. TEG is commonly used in fog machines for concerts and theatre productions. EPA reviewed all available data on this product's effectiveness and safety and concluded that it is capable of killing 98 percent of airborne SARS-CoV-2. TEG may be an irritant for sensitive populations.
