Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
PNEC freshwater sediment:
Koc = 182 (calculated)
K_(susp-water) = 5.46
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment = (K_(susp-water)/ RHO_(susp))*PNEC_water * 1000
= (5.46/1150)* 0.00818 *1000
= 0.03884 mg/kg wwt
= 0.179 mg/kg dwt
----------------------------
PNEC marine water sediment:
Koc=182 (calculated)
K_(susp-water) = 5.46
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_marine water sediment = (K_(susp-water)/ RHO_(susp))*PNEC_marine water* 1000
= (5.46/1150)*0.000818* 1000
= 0.003884 mg/kg wwt
= 0.0179 mg/kg dwt
-----------------------------
PNEC soil:
Koc=182 (calculated)
K_(soil-water) = 5.67
RHO_(soil) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil = (K_(soil-water)/ RHO_(soil))*PNEC_water * 1000
= (5.67/1700)* 0.00818* 1000
= 0.0273 mg/kg wwt
= 0.031 mg/kg dwt
Conclusion on classification
Aquatic acute toxicity
48 h, EC50 (Daphnia magna): > 45.5 mg/L (measured)
72 h, ErC50 (Pseudokirchnerialla subcapitata): 44.8 mg/L (measured)
96 h, LC50 (Danio rerio): 8.18 mg/L (measured)
Aquatic chronic toxicity
72 h, EC10 (Pseudokirchnerialla subcapitata): 29.8 mg/L based on growth (measured)
Biodegradation: Readily biodegradable: 79 % (O2 consumption) after 28 d (EU Method C.4-E)
log Kow = 2.36 (measured), log Koc = 2.26 (calculated)
Classification according to CLP
Based on the data above, the substance has not to be classified for acute or chronic toxicity according to the 10th ATP of the 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.
