Silvicide: feature, composition, application


Silvicide is available in powder or solution form. It is white in color. Here in Nepal, it is mostly available in a bottle of one liter.


  • 0.01% w/v of silver nitrate IP
  • 10% w/v hydrogen peroxide IP

It is known as a universal disinfectant for aerial fumigation and surface/ water disinfection.


Bactericidal, Fungicidal, Virucidal, Sporicidal, and Tuberculocidal


  • Aerial fumigation in pharmaceuticals and hospitals ( OT, ICU, maternity house, etc.)
  • Water and surface disinfection

Usage directions

A certain amount of available Silvicide solution is mixed with demineralized water (DM) before fogging.

  • Aerial Fumigation:- 20% v/v solution of Silvicide with a contact time of 30 minutes.
  • Surface Disinfection:- 5% v/v solution of Silvicide with a contact time of 60 minutes.
  • Water Disinfection:-
Ppm Contact time (hrs)
100 8
500 6
1000 2

The time taken by the germicides to fully disinfect surface/air/water is known as contact time. I have already stated the contact time for different places in the above paragraphs. These values are given in the literature on Silvicide solutions. However, you can even wait for more than the specified contact time before you carry out your work.

My experience with Silvicide

The first time I opened a bottle of Silvicide solution, I did not know that it would have an allergic or burning sensation to the skin. My fingers even got a whitish layer of Silvicide on top of the skin layer. It even remained after washing my hand with soap water.  If you need to work with the Silvicide solution I strongly suggest you wear an examination or nitrile gloves. You also need to wear a disposable cap, apron, and goggles.

For most of the time, you really do not need to be highly precise with the chemical composition, amount of disinfectants used in a room, contact time, etc., due to the following reasons.

  • When fogging is done, rooms will be closed and machines will be covered (if needed). There will not be any user around. Thus, there will not be any risk of an overdose of the disinfectants.

At the end of fogging, some amount of disinfectants may remain in the tank of the fogger machine, which will create an error in your estimated amount. Thus we can use an extra dose of the disinfectants.
