Additional information
Conclusion on classification
Three acute endpoints for three different trophic levels are available. The lowest LC50 is found for fish and is 50.2 mg/L. Three chronic endpoint are available as well, the most sensitive species is Daphnia, with an EC10 of 1.03 mg/L.
The substance is not readily or inherently biodegradable and does not hydrolyse quickly.
The substance has a low log Kow (log kow < 3).
These findings do not lead to classification under Directive (67/548/EEC).
Under Regulation (EU) No 286/2011 (2nd ATP to CLP) based on chronic data, no environmental classification is needed.
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).
