Covid-19 Chemicals

Chemical suitable for the sanitation of the environment

There are numerous chemicals suitable for sanitizing and sterilizing so as to kill and destroy the coronavirus (Covid-19). They likely all have some use in specific contexts

Ecotao Enterprises supplies a selection of chemicals to be used in different contexts.

Hypochlorous acid (HoCL)

This is not to be confused with hydrochloric acid (HoCl)! Hypochlorous acid is actually in the pH range 6-10 as a commercial product called Anolyte Neutral.

This is the one of the safest products to use and arguably the safest product to use in the combat of Covid-19.

See the second half of this video:

We supply two product versions, Eco-Lyte and SAHPRA certified Trifectiv +.

Eco-lyte is a 300-500ppm concentrate, diluted 1:1 (1 liter concentrate and 1 liter clean tap water). The formulation does contain a low level of table salt (NaCL), so the salt
remaining  (<0.2%) could increase corrosion rates of some metals. The product is safe for furniture, equipment, and food.
This product is NCRS registered: Act5GNR529/245793/072/0430. The National Regulator for Compulsory Specifications ( NRCS).

Trifectiv + (SAHPRA number 00000733MD) is a 5% HOCL misting concentrate. 100 milliliters is diluted in 20 liters of water for use.

Virkon S

Virkon S is a powerful antiviral used in the animal industry.  More Virkon information on this site.

Suitable for

  • Surfaces
  • Equipment
  • Vehicles
  • Aerial disinfection
  • Water delivery systems
  • Boot and shoe ftor baths


Virukill is available as a cannister type disinfectant aerosol fogger, defined as a broad spectrum disinfectant and in liquid form for fogging and thermal fog applications.

Aerosol cannister


Active ingredient: Didecyldimethyl­ammonium chloride (DDAC) (a quaternary ammonium compound)


Disinfectant  Concentrations and Contact Times for EPA’s List of Products Effective  against Novel Coronavirus SARS-CoV-2, the Cause of COVID-19

Virukill liquid

Active ingredient, Poly dimethyl ammonium chloride is also on the EPA list to destroy the coronavirus.It is a Broad spectrum disinfection of surfaces against all poultry viruses, bacteria, fungi, mycoplasma, yeasts, algae.

Concentration, 120g/l

Virukill properties

  • Contains a novel and patented quaternary ammonium compound synthesis.
  • Excellent biodegradability and hence low environmental impact.
  • Truly non-corrosive and does not oxidise.
  • Non-toxic at recommended rates.
  • The concentrate has a very low toxicity, LD 50 >4000mg/kg, less than table salt.
  • High surfactant content with excellent wetting and penetrating abilities.
  • Highly active in the presence of organic matter, including hard water and heavy soiling.
  • Not pH-dependant and works at a wide range of temperatures.

Virukill is active against all groups of pathogens (viruses, bacteria, fungi and mycoplasma family groups) at various concentrations.It even works against algae.Objective and internationally respected institutes and researchers have extensively tested Virukill. These include:

  • The South African Bureau of Standards (SABS)
  • The Department of Tropical Diseases at the University of Pretoria (Ondersterpoort
  • The Department of Poultry Diseases at the University of Pretoria (Ondersterpoort)
  • Agricultural Research Council (ARC), Irene

University of the Free State.All tests were certified and conducted using internationally accepted codes of good laboratory practice (GLP). In summary, mostbacteria and fungi were tested using a 1% (1:100) or 0,5% (1:200) Virukill dilution ratio with 10 minutes exposure time and organicloads of 1% skim milk plus 300 ppm water hardness. Skim milk was used because it has a strong inhibitory influence on chemicalcompounds and is ideal, when combined with hard water, for simulating field conditions.Most viruses were tested using 1% (1:100) Virukill dilution ratio with 20 minutes exposure time and organic loads of 1% skimmilk plus 300 ppm water hardness. A minimum 4 log reduction in pathogen population was needed for the dilution ratio to bequalified as effective.

Halamid, Chloramine T

This can be used in thermal foggers . See more on this site.

Halamid can be used in healthcare and public areas

Health care technical bulletin

This product is very stable in solution.


SaniGuard is used undiluted in thermal foggers. It is a 20 litre drum, broad spectrum disinfectant. This fogging solution is DDAC based.

Quatsan 1000


Quatsan bears the SABS 1853 mark. Quatsan is a  twinchain QAC which has has a broad spectrum kill rate, which is second  to none. Safe to use on all surfaces and can be applyed with use of  sprayers, foamers or simply bucket and water. Because of its high  dilution rate, it makes for a vert in-expensive disinfectant.
