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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
Chronic data are available for algae (NOEC > 1 mg/L) (no other measured long-term studies are available).
Classification is based on the available chronic (algae) and acute toxicity data (Daphnia and fish; EC/LC50 > 100 mg/L). The chronic data indicate that the substance is not to be classified as hazardous to the aquatic environment. The data available for chronic classification are conclusive but not sufficient for classification.
The substance is not readily biodegradable, its logKow is < 4. Therefore, the substance is not to be classified as chronically hazardous to the environment.
Based on the available data, the test substance does not meet the criteria for classification as acutely or chronically toxic according to Regulation 1272/2008.
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.
