Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The following relevant key results are currently available for deriving the classification of the substance for the environment:
Daphnia magna 48h-EC50: 1.5 mg/L
Algae 48h-ErC50: 0.41 mg/L; no EC10 or NOEC could be derived.
Readily biodegradable
LogKow: 5.1
Acute (short-term) aquatic hazard:
As the acute ErC50 value for algae is ≤1 mg/L, the substance needs to be classified as Acute 1 according to Table 4.1.0(a).
Chronic (long-term) aquatic hazard:
No chronic value (EC10 or NOEC) could be derived in the studies, therefore classification has to be done only according to the criteria in Table 4.1.0(b)(iii). The lowest acute value is derived for algae with an EC50 value of 0.41 mg/L. In combination with the LogKow of 5.1, the substance should be classified as Chronic 1.
Conclusion:
The substance needs to be classified as Acute 1 (H400) and Chronic 1 (H410) according to Regulation (EC) No 1272/2008 (CLP) and its amendments.
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.
