TEG Vapor Study Reports

Below are the full study reports we've compiled related to the use of Triethylene and Propylene Glycol vapors (theatrical fog) as a disinfectant against viral, bacterial, and fungal microbes, arranged chronologically. Items in red are yet to be located in full. We will update the list as new documents are obtained. Click on the item numbers next to the references to view the full documents. 


There are a lot of documents to absorb here, so a good way to become oriented is with the Excerpts page.


Of particular interest is document #22 produced by the FAA in 2009 regarding disinfecting airplanes.


Also of summary interest are documents #14, 15, & 17.


Toward the bottom of the list are more recent documents, including reports by the FDA, NIH, & EPA and a new report published this month regarding the airborne suspension of speech droplets - document #36.


And finally, if you have questions or additional studies or information to contribute, please email us at info@asepo.org.
