Hygieia-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 Hygieia-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.
