Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to the CLP Regulation (Regulation 1272/2008) and the DSD (Directive 67/548/EC) the substance does not have to be classified for the (aquatic) environment as an acute aquatic hazard, but it is classified as a chronic aquatic hazard category 2 (CLP) and N; R51/53 (DSD).
Since only short-term toxicity studies are available (the long-term toxicity has not been investigated), acute values were used for the classification for long-term aquatic hazard. Of the 3 trophic levels (fish, invertebrates and algae) tested for acute toxicity, fish was the most sensitive (LC50 6.8 mg/L). This value is lower than the 10 mg/L cut-off value for classification as a chronic aquatic hazard category 2 (Regulation 1272/2008) and N; R51/53 (DSD), and the test substance is considered not to be rapidly biodegradable.
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.
