Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
For the calculation of the partition coefficient with EUSES a Log Pow of -1 was used as input parameter.
PNEC freshwater and marine water sediment
K_(susp-water) = 0.979
RHO_(susp) = 1150
Conversion factor (wwt -> dwt): 4.6
PNEC_freshwater sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_water * 1000
= (0.979/1150)* 0.036*1000
= 3.06E-02 mg/kg wwt
= 1.41E-01 mg/kg dwt
PNEC_marine water sediment
= (K_(susp-water)/ RHO_(susp))*PNEC_ marine water * 1000
= (0.979/1150)* 0.0036*1000
= 3.06E-03 mg/kg wwt
= 1.41E-02 mg/kg dwt
PNEC soil
K_(soil-water) = 0.295
RHO_(susp) = 1700
Conversion factor (wwt -> dwt): 1.13
PNEC_soil
= (K_(soil-water)/ RHO_(soil))*PNEC_water * 1000
= (0.295/1700)* 0.036* 1000
= 6.25E-03 mg/kg wwt
= 7.1E-03 mg/kg dwt
Conclusion on classification
Based on the available data the test item has not to be classified 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.
