Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Assessment based on acute median effect value of 40 mg/L found in fish, the assessor has decided to use 40 mg/L as conservative approach. the assessment factors from the guideline were used. The logKow value was determined to be < -1, this was used to determin the PNEC sediment and soil via the equilibtium partitioning method by using EUSES 2.1.
Conclusion on classification
The critical EC50-value of the test substance is determined at 40 mg/L (short-term toxicity study in fish). As in addition, the test substance is determined as being not readily biodegradable, the test substance is to be classified as Aquatic Chronic category 3 (H412) according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008. For the same reasons, according to the criteria in Directive 67/548/EEC, the substance is classified as R52/53.
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.
