Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Conclusion on classification
Aquatic acute classification:
The substance had EC50 values within 1-10 mg/L both in daphnia and algae. Based on these results, Aquatic acute 1 /H400 with an M-factor of 1 is required.
Aquatic chronic classification:
The substance is estimated to be non-readily biodegradable.
For algae: EC10 value for growth rate (estimated using raw data, and being a chronic toxicity data) ranges 0.1-0.34 mg/L, so using CLP Table 4.1.0 (b)(i), a classification as Aquatic chronic 2/H411 would be warranted.
For daphnia: no chronic data are available, so the EC50 value should be used. Using CLP Table 4.1.0 (b)(iii), a classification as Aquatic chronic 1/H410 is warranted, with an M-factor of 1.
The worst-case of these two classification methods is retained: Aquatic chronic 1/H410, with an M-factor of 1.
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.
