Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 96-hour LC50 for fish, the 48-hour EC50 for crustacea are <1 mg/L. The 72-hour ErC50 for algae was > 100 mg/L. The chronic NOECs for fish and crustacea are <0.1 mg/L. Additionally, the substance is considered not readily degradable. Based on all the available data, 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, algae and fish. Therefore, the M factor is 10, based on the 96 hour LC50 of 0,003 mg/l in fish Oncorhynchus mykiss (rainbow trout) and based on the 48 h EC50 of 0,0001 mg/L in Algae (Daphnia magna (Water flea). 

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, chronic data were available in daphnia; acute data were also available. However, the acute data drive the classification. The lowest reported effects in chronic data were the 216 days of 0,000568 mg/l in fish (Pimephales promelas (fathead minnow). The test substance is Not biodegradable. Therefore, the M factor is 10.
