Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Formula for the calculation of PNECsoil using the equilibrium partitioning approach:

PNEC(soil) = (Ksoil-water x PNEC(aqua) / RHOsoil) * 1000

PNEC(soil) Predicted No Effect Concentration in sediment [mg/kg, wet weight]

Ksoil-water partition coefficient sediment / water [0.439 m3/m3]

RHOsoil bulk density of soil matter [1700 kg/m3]

PNECaqua Predicted No Effect Concentration in water [as above]

Molecular weight used: 220.

Conclusion on classification

The very low toxicity of this substance to aquatic species coupled with its ready biodegradability mean that it does not meet the criteria for classification.
