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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
All short-term aquatic toxicity studies reported EC50/LC50 values well above 100 mg/L, and well above the water solubility of the target substance. However, the target substance does not biodegrade to any appreciable extent (10% in 28 days and 6.2% in 35 days). It is very poorly water-soluble (water solubility below the detection limit of 0.06 mg/L) and is hydrolytically stable (no hydrolysis observed in an OECD 111 study) and did show some inhibition to green algae in the OECD 201 study. Due to these reasons, it is considered prudent to apply the GHS 'safety net' classification of Aquatic Chronic 4 to this substance.
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.
