Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test substance has an estimated 48-hour EC50 of 0.079 mg/L in Daphnia and estimated 72-hour EC50 in algae of 0.11 mg/L. Additionally, the log Kow is predicted to be 5.9 and the test substance is predicted to be not readily biodegradable. Therefore, the test substance is classified as Acute Cat 1 (H400: Very toxic to aquatic life) and Chronic Cat 1 (H410: Very toxic to aquatic life with long lasting effects) according to EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
In accordance with article 10 of the CLP Regulation (EC) No 1272/2008, if an M-factor is not yet given in Part 3 of Annex VI to the CLP Regulation, an M-factor should be determined and a scientific justification provided, when classifying substances for Acute Category 1 or Chronic Category 1. For this substance, adequate acute aquatic data are available in fish, aquatic invertebrates, and algae. An Acute M-Factor is based on the lowest reported effects in the most sensitive species, aquatic invertebrate. Therefore, the M factor is 10 based on the 48 h EC/LC50 of 0.079 mg/L in aquatic invertebrates and the 72 h EC/LC50 of 0.11 mg/L in algae.
In accordance with article 10 of the CLP Regulation (EC) No 1272/2008, if an M-factor is not yet given in Part 3 of Annex VI to the CLP Regulation, an M-factor should be determined and a scientific justification provided, when classifying substances for Acute Category 1 or Chronic Category 1. No Chronic data were available in fish, invertebrates, and algae. The classification was based on acute aquatic data and the fact that the substance is not readily biodegradable. Therefore, a chronic M-factor cannot be calculated.
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.
