Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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, freshwater sediment, marine sediment, soil and the STP. The PNECs were calculated using endpoints obtained using freshwater aquatic species and STP microorganisms. No PNECS were calculated for air, or secondary poisoning as they are deemed to be unnecessary. The PNECs are as follows:
PNEC freshwater = 0.011 mg/L
PNEC marine water = 0.0011 mg/L
PNEC intermittent = 0.105 mg/L
PNEC STP = 10 mg/L
PNEC sediment (freshwater)= 0.128 mg/kg dw
PNEC sediment (marine)= 0.013 mg/kg dw
PNEC soil= 0.011 mg/kg dw
Conclusion on classification
No classification is triggered based on the available data. The lowest acute L(E)C50 is 10.5 mg/L, and as such the substance does not attract classification for acute aquatic toxicity. No chronic classification is attracted as the substance is considered rapidly degradable under current CLP guidance and has no significant potential for bioaccumulation with a log Kow of 2.4.
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.
