Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Read-across from a sediment-water chironomid toxicity test according to OECD Guideline 218 with the monosodium salt of cyanuric acid. 

Key value for chemical safety assessment

EC50 or LC50 for freshwater sediment:
1 146.57 mg/kg sediment dw
EC10, LC10 or NOEC for freshwater sediment:
1 146.57 mg/kg sediment dw

Additional information


1. Based on the experimental results obtained with the analogue monosodium salt of cyanuric acid, monohydrate (28 d-EC50 > 1000 mg/kg sediment dw ; 28 d- NOEC = 1000 mg/kg sediment dw) and the molecular weights, the read-across approach is applied and the 28 d-EC50 and 28 d-NOEC for substance trisodium cyanurate are calculated to be higher than 1146.57 mg/L and 1146.57 mg/L, respectively.
