Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The results of the aquatic toxicity studies all provide effect concentrations > 100 mg/L. As such no classification in accordance with EU CLP (EC No. 1272/2008, as amended) is warranted for aquatic acute toxicity. With regards to chronic effects, no fish or invertebrate data is available or required at the current tonnage band (an algal NOEC of 3.16 mg/L was determined). As the substance is not readily biodegradable consideration of any acute effects can be taken into account for endpoints with no chronic results. As the acute fish and invertebrate studies both provided effect concentrations of > 100 mg/L, no classification in accordance with CLP is warranted for aquatic chronic effects.
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.
