Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In the absence of sediment toxicity data, the PNEC sediment is calculated using the equilibrium partitioning method (EPM) as follows (in accordance with ECHA Guidance on Information Requirements, PartB):


PNECsediment =(0.783 + 0.0217 x Koc) x PNEC water.


Estimated Koc forTCPP=289.1 - 1604 L/kg (by following a precautionary approach, the lowest estimated Koc value of 289.1 L/kg will be used in the calculation); PNEC water =0.42 mg/L


Therefore, PNECsediment= 2.96 mg/kg is calculated forTCPP.
