Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
PNECs have been derived for freshwater, marine water, intermittent releases and the STP using the available endpoints. The PNECs were calculated using endpoints obtained using freshwater aquatic species and STP microorganisms. PNEC values for sediment were derived by the equilibrium partitioning method (EPM). No PNECS were calculated for air, or secondary poisoning as they are deemed to be unnecessary. The PNECs are as follows:
PNEC freshwater = 0.0044 mg/L
PNEC marine water = 0.00044 mg/L
PNEC intermittent = 0.044 mg/L
PNEC STP = 1mg/L
PNEC sediment (freshwater) = 0.144 mg/kg dw
PNEC sediment (marine) = 0.014 mg/kg dw
PNEC soil = 0.026 mg/kg dw
Conclusion on classification
The lowest acute L(E)C50 is 4.4 mg/L, and as such the substance does not attract classification for acute aquatic toxicity. As the substance is considered rapidly degradable under CLP guidelines and as the BCF is less than 500 L/kg, the substance does not attract any classification for chronic toxicity.
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.
