Huwa-San TR-50 is a 50% concentrated formulation of hydrogen peroxide (H2O2) uniquely stabilised with ionic silver chemistry.
Hydrogen peroxide is a transparent colourless and odourless disinfectant liquid which post disinfection quickly degrades into water and oxygen. The unique ionic silver stabilisation technology in Huwa-San TR-50 increases the stability of the hydrogen peroxide solution, without the undesirable residual effects from other potential stabilising agents, such as acids. In water Huwa-San has a proven 5 week half life.
This stabilising Huwa-San PEROXIDE technology is an integral component in making Huwa-San TR-50 an extremely powerful non-residual disinfectant.
With a contact time of five minutes, Huwa-San is proven to kill 99.999% of all known bacteria at 3% H2O2 concentration.
Conforms to British (BS) and European (EN) regulatory standards for efficacy against viruses, bacteria and fungi, across a range of hard surfaces.
