Chlorine dioxide (ClO2) is not a new disinfectant; it was discovered in 1811 by Sir Humphry Davy.
It is well known as one of the world's most effective disinfectants. Since the 1950s, it has been primarily used for treating drinking water, and previously, on a larger scale, only in industries, because ClO2 is a gas by nature.
In 1992, Göran Holmberg at Xinix (Sweden) succeeded in stabilising it into a liquid state. Over the past 10 years, Xinix has further developed chlorine dioxide products with a long shelf life – now available to everyone.
