Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 PNEC derivation was as follows justified:
PNEC freshwater sediment:
K_(susp-water) = 4.55
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment
= (K_(susp-water)/ RHO_(susp)) * PNEC_water * 1000
= (4.55/1150) * 0.596 * 1000
= 2.358 mg/kg wwt
= 10.85 mg/kg dw
PNEC marine water sediment:
K_(susp-water) = 4.55
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine water sediment
= (K_(susp-water)/ RHO_(susp)) * PNEC_marine water * 1000
= (4.55/1150) * 0.0596 * 1000
= 0.2358 mg/kg wwt
= 1.08 mg/kg dw
Conclusion on classification
Aquatic acute toxicity
96 h, LC50 (Oncorhynchus mykiss): 42 mg/L
48 h, EC50 (Daphnia magna): > 91 mg/L
72 h, ErC50 (Algae): 23.9 mg/L
72 h, NOEC (Algae): 5.956 mg/L
Aquatic chronic toxicity
21 d, NOEC (Oncorhynchus mykiss): 50 mg/L
21 d, NOEC (Daphnica mgna): 22.2 mg/L
Biodegradation: Readily biodegradable: 85 % (O2 consumption) after 28 days (OECD 301 F);
Classification according to CLP
Based on the data above, the substance has not to be classified for acute and chronic toxicity according to Regulation (EC) No 1272/2008 (CLP).
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.
