Description of key information

Additional information

The substance hydrolyses rapidly in use to release available chlorine moieties in the form of HOCl and CYA. There is no potential for bioaccumulation of NaDCC.

NaDCC has Log Pow < 1, rapidly hydrolyses to CYA, and is highly soluble in water. In addition, the chlorinated isocyanurates are highly reactive with many biological compounds such as proteins and enzymes and are therefore unlikely to bioaccumulate. A calculation of BCF using EPIWIN v3.2 software indicates that NaDCC has a BCF = 1.932 (Bland S (2007)).

CYA is also unlikely to bioaccumulate, based on its low Log Pow (-1.31). A calculation of BCF using EPIWIN v3.2 software indicates that CYA has a BCF = 3.165 (Bland S (2007))
