Hydrocyn has been tested on SARS-CoV-2 in collaboration with the National Veterinary Institute (SVA) in Uppsala.*

The virus culture with SARS-CoV-2 was exposed to Hydrocyn® aqua directly from the bottle. The effect against the virus was tested after 30 seconds, 1 minute and 2 minutes. After already 30 seconds, the level of alive and active virus had been reduced by 99.9%. Thus, most of the virus had been killed (deactivated) and was no longer contagious.

Hydrocyn has also shown a significant effect on inactivation of previous strains of coronavirus e.g., HCoV-229E.

* In collaboration with the Swedish Veterinary Institute (SVA), tests have been carried out with Hydrocyn aqua on a virus culture of the new Coronavirus (SARS-CoV-2) that causes covid-19. The results showed that 99.98% of the virus particles were inactivated – and thus not contagious.
