Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
Refer to the summary table in the Aquatic toxicity endpoint summary (6.1 endpoint summary). Aquatic invertebrates (Daphnia Magna) were found to be the most sensitive species relevant for classification for environmental hazards. The 48-hours EC50 for immobilisation in Daphnia was 35 mg/L; with reference to Table 4.1.0 (a) of Annex 1 to the CLP regulation (as amended by the 2nd ATP to the CLP regulation, Commission Regulation 286/2011), the substance therefore does not meet the criteria for classification as Category Acute 1 (48 hour EC50 ≤ 1 mg/L).
There are adequate chronic toxicity data for the substance, Daphnia Magna was found to be the most sensitive species relevant for classification for environmental hazards. The 21-days NOEC for reproduction of Daphnia was 1.24 mg/L; and the substance was found not to be rapidly biodegradable. With reference to Table 4.1.0 b(i) to the CLP regulation (as amended by the 2nd ATP to the CLP regulation, Commission Regulation 286/2011), the substance therefore does not meet the criteria for classification as Chronic Categories (NOEC ≤ 1 mg/L).
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.
