Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to aquatic invertebrates

Description of key information
An OECD 202 study (Daphnia magna immobilisation test) has been carried out. An EC50-48h = 60 mg/L was observed. Later on, a chronic toxicity on the same species with the same batch of test substance didn't register any effect on reproduction or survival up to 32 mg/L on a period of exposure of 21 days.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 60 mg/L
Additional information
Applying OECD 202 guideline, an EC50-48h = 60 mg/L has been obtained, that corresponds to "harmful" effects to Daphnia.
The lowest tested concentration of the short term study, 39 mg/L did not show immobilisation in 48 hours
Further to this test, a chronic toxicity test has been done to investigate potential effects on daphnia reproduction. Results are described in the relevant section. No effect was observed at the highest tested concentration, 32 mg/L, either on reproduction or on survival of parent daphnids, during the 21 days of the test.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).
