Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The assessment factor of 10 is applied to the most critical long-term effect parameter obtained (NOEC of 5.6 mg/L), resulting in a PNECaqua-freshwater of 0.56 mg/l:

PNECaqua-freshwater = 5.6 mg/L / 10 = 0.56 mg/L.

Considering marine water, the same data can be used for the hazard assessment, however, all assessment factors are tenfold higher compared to freshwater conditions (refer to ECHA (2008) “Guidance of Information Requirements and Chemical Safety Assessment, Chapter R.10: Characterisation of dose-response for environment”; Table R.10-5):

PNECaqua-marine water = 5.6 mg/L / 100 = 0.056 mg/L.

Conclusion on classification

The test item needs not to be classified according to Regulation EC No 1272/2008 due to the aquatic toxicity test results.
