Decon 7 & Covid-19

D7 contains surfactants, mild solvents, inorganic salts, a low concentration of hydrogen peroxide (~3.5%), a hydrogen peroxide activator, and water.  The surfactants soften the cell walls of pathogens which allows the activated peroxide to penetrate to the interior for complete kill.  This unique combination of mild ingredients works synergistically to kill persistent biological pathogens which has been demonstrated in testing at numerous government and private facilities and in many field applications – outperforming formulations that contain much harsher chemicals.

The D7 chemistry is licensed by Decon7 Systems from Sandia National Laboratories, a U.S. Government research and development laboratory, where it was originally developed to decontaminate chemical and biological warfare agents for military and homeland security applications.  Decon7 Systems has greatly expanded its use to many other applications.  Recent laboratory testing and field applications have demonstrated that D7 has high efficacy against pathogens of concern to human health, and in agriculture and food processing such as Listeria, E. coli, Salmonella, the African Swine Fever virus, the Porcine Epidemic Diarrhea Virus, Salmonella and E. coli biofilms, Avian Influenza, and Bacillus spores.  Most of these tests were conducted in the presence of a high organic or soil loading.  These results clearly demonstrate that the use of D7 can significantly improve both human and animal health.

D7 can effectively inactivate coronaviruses.  In tests at Kansas State University, D7 was shown to rapidly and completely inactivate a >5Log10 concentration of Bovine Coronavirus (BCV) with a one minute contact time even in the presence of a 50% organic loading¹. Note that in the report for these tests referenced below, D7 is referred to by its development name of DF-200.  Based on these results, D7 can effectively be used to disinfect facilities such as hospitals, railway stations, and airports against coronaviruses and other pathogenic organisms – even in areas with high organic or soil loads.

D7 can be easily deployed.  It can be dispersed as a highly stable foam through existing foam generating equipment.  When deployed as a foam, it clings to vertical and downward facing surfaces for 30 minutes or more to achieve long contact times against persistent toxic materials including biofilms.  It can also be deployed as a liquid spray either through large-scale sprayers or from a hand-held spray can (i.e., BDAS+) which enables rapid deployment within seconds.  D7 can also be deployed as a fog (or mist) from aerosol-generating devices primarily for interior decontamination – which is the ideal deployment method for large spaces potentially contaminated with coronaviruses.  Once D7 comes into contact with bacteria or viruses either in the air or on surfaces, these pathogens are quickly killed or inactivated reducing the risk of infections to people in the area.

Once this solution has been used on a surface and allowed the time to decontaminate the virus will not be able to return to the surface for up to 5 days when the solution can be reapplied which offers greater operational resilience and staff confidence.
