Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is not classified for the environment as the substance is readily biodegradable and does not fulfill the criteria required for classification as an acute aquatic hazard.
The lowest EC50 value is 82 mg/L in daphnia, the substance is readily biodegradable and has a Log Kow > 9.4. In accordance with ECHA Guidance on Information requirements and chemical safety assessment Chapter R11: PBT assessment (page 28) on determination of bioaccumulation potential states: at very high log Kow (>6), a decreasing relationship between BCF and Log Pow is observed. The calculated log Kow as > 9.4, in line with the cut off value of 10 which is cited in REACH guidance as a value suggesting that that BCF in aquatic organisms would be less than 2000 in a weight of evidence approach. Further evidence of very limited uptake stems from the long term algae NOEC which is far greater than the solubility limit of the substance.
Conclusion on classification
The substance is not classified for the environment as the substance is readily biodegradable and does not fulfill the criteria required for classification as an acute aquatic hazard.
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).
