Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
GLP study reporting EL50 (48 h) > 1000 mg/L (OECD 202)
Non-GLP study reporting EC50 (48 h) as 2.7 mL/L
GLP study for a close structural analogue reporting EC50 (48 h) > 1000 mg/L when expressed in terms of loading rate and EC50 (48 h) > 2.38 mg/L when expressed in terms of measured calcium (OECD 202)
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 1 000 mg/L
Additional information
Methodological deficiencies in a non-GLP study render the results unreliable for use in risk assessment or classification. However, a modern GLP investigation found no evidence of acute toxicity to Daphnia magna and the NOEC was 1000 mg/L. These data are supported by the results of a GLP investigation involving a close structural analogue of the test substance.
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.
