How Virkon Disinfectant Powder Works

The Virkon solution is activated by adding the powder to water.

Virkon disinfectant is a unique, synergised oxidising system based on potassium monopersulphate - works by the physical destruction of pathogens.

The potassium monopersulphate oxidises proteins in bacteria cell walls and viral structures. This is what disrupts the bacteria's physical structure and the viability as pathogens.

Contains a surfactant - combines cleaning and disinfection in one operation.
