Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
The test substance can be classified as non-toxic to fish up to the limit of its solubility, namely 0.0008 mg/L.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 1 175 µg/L
Additional information
The substance was tested over a range of concentrations achieved by dilution from a supersaturated stock solution. Analysis showed that the maximum concentration achieved was 1.372 mg/L at the beginning of the test which declined to 0.978 mg/L after 48 hours. The solubility of the substance in the test water was determined to be 0.0008 mg/L. Results are based on mean measured concentrations. Some immobility was observed from the second lowest dose of 0.0044 mg/L increasing to a maximum of 35% immobilisation at the measured level of 1.175 mg/L. Care should be exercised in the interpretation of these data, since the substance was tested at levels above the water solubility. All immobilisation recordings were at concentrations higher than the water solubility of the substance. Therefore, the substance can be classified as non-toxic to invertebrates up to the limit of its solubility, namely 0.0008 mg/L.
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.
