Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 in vivo studies of skin and eye irritation (where cyanuric acid was non-irritating);so the same results can be extrapolated to trisodium cyanurate.

Key value for chemical safety assessment

Skin irritation / corrosion

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Eye irritation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not irritating)

Additional information

Read-across:

1. Based on the experimental results obtained with the analogue cyanuric acid (72h-primary dermal irritation index (PDII)= 0) , the read-across approach is applied and the 72h-primary dermal irritation index (PDII) for substance trisodium cyanurate is calculated to be 0 (skin irritation).
2. Based on the experimental results obtained with the analogue cyanuric acid (72h-overall irritation score= 0.3) , the read-across approach is applied and the same result can be extrapolated for substance trisodium cyanurate (eye irritation).

Justification for classification or non-classification

In the in vivo skin and eye irritation studies cyanuric acid was non-irritant and therefore requires no classification under DSD or CLP
