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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
All assessment and conversion factors used in the above PNEC calculations were taken from the ECHA guidance document "Guidance on information requirements and chemical safety assessment; Chapter R.10: Characterisation of dose [concentration]-response for environment" along with appropriate equations and methodologies.
Conclusion on classification
Using the 'worst case' aquatic toxicity value; Acute daphnia 48h EC50 = 0.037 mg/L (Sewell & McKenzie, 2005) and based on the fact that no biodegradation was observed, the classification for this endpoint will be:
N; R50/53 according to Directive 67/548/EEC;
and Aquatic Chronic 1; H410 and Aquatic Acute 1; H400 according to Regulation (EC) no 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).
