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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to the ECHA guidance on information requirements and chemical safety assessment, Part E for some substances it may not be possible to undertake a full quantitative risk assessment because of the inability to calculate a PNECwater. We believe that this is the case here: no effects are observed in short -term tests, while test concentrations were considerably high (up to ca. 100 mg/L). At none of the tested concentrations an effect was observed. For derivation of the PNECs, the lowest tested concentration was used as a starting point. However, it is most likely that these PNECs are significantly lower than what they are in reality due to lack of more specific data. It was therefore concluded that for this substance it is warranted that a qualitative risk assessment is conducted.
Conclusion on classification
On the basis of all available information, the substance does not require classification for any environmental hazard (EC1272/2008).
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.
