It is a colourless solid.
Mechanism of action.
Dichloroisocyanuric acid is an oxidizer, reacting with water to form chlorine gas and nitrogen trichloride liquid.
Although the bleaching agent in most chlorine based bleach is sodium hypochlorite, the sodium salt of dichloroisocyanuric acid, sodium dichloroisocyanurate, is the active ingredient in commercial disinfectant bacteriocides, algicides, and cleaning agents., for example the pulverized cleanser Comet.
