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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The values derived as PNECs above are fully in line with observed results for aquatic toxicity as this substance shows only effects, if at all, to aquatic organisms way above all thresholds for classification & labelling (100 mg/l) for some species even orders of magnitudes above. In addition the suubstance is readily biodegradable as shown in the data sections and a hazard to aquatic organisms is not expected.
Conclusion on classification
Based on available data substance is neither classifiable for acute nor chronic aquatic toxicity according to CLP (EC No 1272/2008)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
