る。On the other hand, bleaching powder is a useful compound used for disinfection and sterilization of septic tanks and pools, but isocyanurate (organic bleaching powder), because it is also a strong oxidizer.
When mixed with organic compounds such as oil, fats and oils, reducing agents, chlorinated amines, etc., there is a danger of heat generation, ignition and explosion. Therefore, there is no example in which the bleached powder contains an organic substance. There is only known an example in which a dilute aqueous solution of sodium hypochlorite is mixed with an organic polymer surfactant as a viscosity modifier.
