Hydrogen peroxide is used as a natural alternative sanitiser to chlorine and other strong chemicals.
The chemical formula for hydrogen peroxide is H2O2 and is created naturally in the environment or artificially in a laboratory.
In the environment hydrogen peroxide is created in the atmosphere when ozone comes into contact with water in the presence of moisture.
Ozone (O3) is composed of free oxygen (O2) plus an extra atom of oxygen. This extra atom of oxygen can split very easily and does so when it comes into contact with water. The water (H2O) then becomes hydrogen peroxide (H2O2).
