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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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