Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The log kow of CYA is - 1.31 indicating no potential to bioaccumulate. In a study to determine cyanuric acid residues in catfish and trout following oral administration of 20 mg/kg cyanuric residues had decreased to a similar level to the controls by day 3. Cyanuric acid does not have any potential to bioaccumulate.
Key value for chemical safety assessment
Additional information
The Log Kow of cyanuric acid is ≤ 3. In a supporting study in catfish and trout (Reimschuessel et al 2009) cyanuric acid was administered as a single oral dose at 20 mg/kg bw. Cyanuric acid residues in all dosage groups on day 3 had decreased to a level similar to the controls. Cyanuric acid t1/2 was less than 1 day in catfish and between 1 and 2 days in trout. Cyanuric acid has no potential to bioaccumulate.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
