Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Administrative data
Link to relevant study record(s)
Description of key information
Long-term aquatic toxicity test on aquatic invertebrates was performed using the analogous substance isocyanuric acid (CAS no.: 108-80-5), that is a hydrolysis product of cyanuric acid. The Maximum non-observable effect concentration (NOECr) was determined to be 32.00 mg/L.
Key value for chemical safety assessment

Additional information
Long-term aquatic toxicity test (study 97-0704-FGO_en) on aquatic invertebrates was performed using the analogous substance isocyanuric acid (CAS no.: 108-80-5), that is a hydrolysis product of the hydrolysis of cyanuric acid.
- The 14 day 50% lethal concentration (LC50) for Daphnia Magna was determined to be 12.39 mg/L (95% confidence interval: 7.99 mg/L to 19.61 mg/L) (Probit method)
The 21 day 50 % lethal concentration (LC50) for Daphnia Magna was determined to be 9.55 mg/L (95% confidence interval: 6.22 mg/L to 14.52 mg/L) (Probit method)
- The 14 day 50% reproduction inhibition concentration (ErC50) for Daphnia Magna was determined to be 9.36 mg/L (95% confidence interval: 1.32 mg/L to 42.77 mg/L) (Probit method)
- The 21 day 50% reproduction inhibition concentration (ErC50) for Daphnia Magna was determined to be 65.86 mg/L (95% confidence interval: 54.47 mg/L to 82.70 mg/L) (Moving average method)
- Maximum non-observable effect concentration (NOECr) was determined to be 32.00 mg/L.
- Lowest concentration (LOECr) at which a significant difference with the control group can be observed was determined to be 100.00 mg/L (The above concentrations are values based upon all the established values).
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.
