The “Most Proven” Ultimate Virucidal Disinfectant


Virkon® S, the premier broad spectrum virucidal veterinary disinfectant, is recognised by industry and governments worldwide as a disinfectant of choice for livestock disease prevention and control.
Virkon® S’ patented formulation is unique. No other disinfectant has the same powerful composition. In terms of efficacy Virkon® S has been proven highly effective against 65 strains of virus in over 19 viral families, 400 strains
of bacteria and over 100 strains of fungi. This list of proven efficacy includes the major OIE List A diseases of concern;
Avian Influenza (H5N1), Newcastle Disease, Classical Swine Fever (Hog Cholera) and Foot and Mouth Disease.

Virkon® S’ versatility provides the flexible solution for; surface, water and aerial disinfection, in hard water, on porous surfaces, at low temperatures and in the presence of organic challenge.

Virkon® S combines greater application flexibility and broad spectrum activity with efficacy against viruses, bacteria and fungi at low temperatures, in hard water, on porous surfaces and against organic challenge.

Mode of Action
Virkon® S oxidizes sulphur bonds in proteins and enzymes disrupting the function of the cell membrane causing rupturing of the cell wall.

There is no evidence to suggest that bacterial disease causing organisms develop resistance towards Virkon® S as opposed to other disinfectant types.

Virkon® S is meticulously controlled during the manufacture process to be a balanced, stabilized blend of peroxygen compounds, surfactant, organic acids and an inorganic buffer system.


Environmental Profile
Virkon® S is an oxygen based disinfectant chemistry containing simple organic salts and organic acids. The active ingredient in Virkon® S, decomposes by a variety of routes within the environment, in soil and water, breaking down to form the harmless substances, potassium salts and oxygen.

Three-quarters of the ingredients of Virkon® S are inorganic, which decompose in the physical environment to naturally occurring simple inorganic salts. The remaining, organic components, are classified as readily biodegradable according to standard OECD and EU tests.

Virkon® S is not classified as R53, persistent in the environment, according to the standard European process for the classification and labelling of chemical preparations.

Independent studies have shown that diluted Virkon® S should not, when used as directed, pose any threat to sewage treatment facilities.

User Safety
The results of independent studies carried out in accordance with OECD and EU guidelines indicated that Virkon® S powder concentrate does not display effects of acute toxicity by exposure to skin or by ingestion. As a result Virkon® S is not classified as harmful or toxic according to the standard European process for the classification and labelling of chemical preparations.

When tested in accordance with OECD and EU test guidelines a 1%, in-use dilution, of Virkon® S does not cause irritation to eyes or skin.

Virkon® S, powder and in-use dilution (1%) does not cause effects of sensitisation when tested to OECD and EU guidelines.
