Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The PNEC for the aquatic environment are derived from the lowest effect level observed in the available acute aquatic toxicity tests by applying the relevant assessment factors to the lowest L(E)C50 in accordance with ECHA Guidance R.10.

PNEC aqua (marine water):

The PNEC for the aquatic environment are derived from the lowest effect level observed in the available acute aquatic toxicity tests by applying the relevant assessment factors to the lowest L(E)C50 in accordance with ECHA Guidance R.10

PNEC aqua (intermittent releases):

The PNEC for the aquatic environment are derived from the lowest effect level observed in the available acute aquatic toxicity tests by applying the relevant assessment factors to the lowest L(E)C50 in accordance with ECHA Guidance R.10.

PNEC STP:

PNECSTP can be calculated via biodegradation studies or ASRI studies where the concentration where no toxicity to microorganisms was observed (can be considered NOEC). An assessment factor of 10 should be used when evaluation PNECSTP in this way.

PNEC sediment (freshwater):

Wet weight PNECs were calculated with using equilibrium partitioning as described in Guidance R.10 & R.16, conversion to dry weight was performed with factor of 4.6.

e.g. 1: Kpsusp= Weight fraction organic carbon in suspended matter (0.1) x partition coefficient organic carbon-water(Koc)

2: Ksusp-water= fraction water in suspended matter(0.9)+(fraction solids in suspended matter (0.1) x (Kpsoil / 1000) x density of solid phase(2500))

3: PNECwet.sediment = (Ksusp-water/bulk density of wet suspended matter(1150)) x PNECwater x 1000

4: PNECsediment = PNECwet.sediment x 4.6

Conclusion on classification

The substance is not classified for the environment.
