Huwa-San is a disinfectant based on hydrogen peroxide.

Hydrogen peroxide (H2O2) is a transparent, colourless and odourless disinfectant liquid which is mixable in any ratio with water. After reaction, it decomposes into water (H2O) and oxygen (O2).






The main difference between Huwa-San and regular hydrogen peroxide, is in the presence of a stabilizing agent. As H2O2 is not stable and slowly decomposes into oxygen and water, a stabilizer in the form of a small amount of silver is added. The silver is used to increase the stability of the hydrogen peroxide solution.



Our procedure of combining hydrogen peroxide and the silver stabiliser is unique worldwide and based on the original Huwa-San technology, which was further developed at Roam Technology over the last 15 years.

Our Technology is unique as no other stabilising agents, like acids for instance, are needed to stabilise our peroxide. All of this makes Huwa-San Technology products non-residual and extremely powerful disinfectants.


Huwa-San is a one stop biocidal product that is effective against bacteria, fungi, yeast, spores, viruses and even mycobacteria and therefore our products can be used in many application fields to disinfect water, surfaces, tools and even big empty areas through vaporisation.

Over the last 15 years, Huwa-San products were tested extensively on lab-scale and on many field trials all around the world. The abundance of information within the broad application spectrum of Huwa-San combined with the technical knowledge of the Roam staff has been the key to our worldwide success.
