Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Reliable aquatic toxicity tests (all reliability category 1) are available for freshwater algae (Scenedesmus subspicatus), freshwater invertebrates (Daphnia magna, acute and long-term), freshwater fish (zebra fish, acute) and sewage treatment plant microorganisms (activated sludge respiration inhibition test, 3 hours). In all sort-term tests, nominal limit concentrations far above the actual water solubility of the submission substance were used (77 or 1000 mg/L). In the long-term test with Daphnia magna, due to the sparingly soluble properties of the test item, the study was performed with the water accommodated fraction (WAF) prepared according to the OECD Series on Testing and Assessment Number 23: "Guidance Document on Aquatic Toxicity of Difficult Substances and Mixtures": The WAF was prepared with M4-Medium. However, no signs of toxicity were observed in any of these tests. Thus, the submission substance was demonstrated to be non-toxic to freshwater organisms at water saturation level.
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.
