Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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.
