Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Acute test results for freshwater algae, invertebrates and fish were as follows:
Scenedesmus subspicatus: 72 -h EbC50= >2.2 mg/L / 72-h ErC50= >2.2 mg/L
Daphnia magna: 48-h EC50= 0.286 mg/L;
Oryzias latipes: 48-h LC50= 1.84 mg/L;
Long-term reproduction study for freshwater
Daphnia magna long-term reproduction study (21 d); NOEC-value = 56.7 µg/L.
Acute test results for marine or estuarine water
Americamysis bahia: 96-h LC50= 0.0372 mg/L
Additional information
The long-term study on Daphnia magna was required within the Substance Evaluation (SEv) process in order to assess the properties of the test item and to decide whether it is toxic (T) in accordance with section 1 of Annex XIII of the REACH Regulation. Furthermore, this information was needed in order to derive Predicted No Effect Concentration (PNEC) for refinement of possible risks for the aquatic environment. Results with the NOEC-value of 56.7 µg /L on the reproductive output of Daphnia magna show that the substance is not toxic (not T).
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.
