Indications & Uses

Halazone tablets for solution (4 mg) help make water safe to drink by clearing it of the bacteria and germs that cause water-borne diseases. Each 100 mg tablet releases 2 mg of chlorine, which is enough to disinfect 1 litre of water. To use, dissolve one tablet in one litre of water and let it stand for 30 minutes to take effect. The water is then ready for drinking.

Pharmacology

Halazone works as a disinfectant mainly through the hypochlorous acid (HClO) it releases. When the tablet dissolves in water, the chlorine-nitrogen bonds in the compound break down by hydrolysis and give off hypochlorous acid:

(R1)(R2)NCl + H2O → HOCl + (R1)(R2)NH

Hypochlorous acid is a strong oxidizer and chlorinating agent. It destroys or denatures many organic compounds, and that is how Halazone kills bacteria in water.

Halazone Tablets are an effective bactericidal purifier for drinking water in small quantities.
