Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
1)
PNEC sediment using Equilibrium Partitioning Method:
The
following formula is applied:
PNECsed= Ksusp-water/RHOsusp*PNECwater*1000
Where:
PNECsed = Predicted No Effect Concentration in sediment [mg. kg-1of wet sediment]
Ksusp water = partition coefficient suspended matter water [m3. m-3]
RHOsusp = bulk density of wet suspended matter [kg. m-3]
PNECwater = Predicted No Effect Concentration in water [mg. l-1]
For Direct Black 19 the formula with the values is:
PNEC sediments = (0,979/1150) * 0,876 * 1000 = 0,0746 mg/kg
Ksusp
water= Fwatersusp+ Fsolidsusp*Kpsusp/1000*RHOsolid
Kpsusp=
Focsusp*Koc
The value of Ksusp -water of 0,979 is consistent with the calculated value with EUSES 2.1.1.
2) PNEC marine sediment using Equilibrium Partitioning Method:
Being marine PNEC usually derived by freshwater PNEC with an adding assessment factor of 10, consequently the marine sediment PNEC can be directly derived from PNEC sediment with an assessment factor of 10.
PNEC marine sediments = 0,0746 * 0,1 = 0,0746 mg/kg
3)PNEC soil using Equilibrium Partitioning Method:
The following formula is applied:
PNECsoil= Ksoil-water/RHOsoil*PNECwater*1000
Where:
PNECsoil = Predicted No Effect Concentration in soil [mg. kg-1]
Ksoil
water = partition coefficient soil water [m3. m-3]
RHOsoil =bulk density of wet suspended matter [kg. m-3]
PNECwater = Predicted No Effect Concentration in water [mg. l-1]
PNEC soil = (0.295/1700) * 0.876 * 1000 = 0,152 mg/kg
Ksoil
water= Fairsoil*Kair-waterl+Fwatersoil+
Fsolidsoil*Kpsoil/1000*RHOsolid
Kpsoil=
Focsoil*Koc
Conclusion on classification
No classification is warranted under the Regulation (EC) No 1272/2008.
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.
