Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In a short-term toxicity study with daphnia magna the 48 hour EC50 was determined to be > 100 mg/L.

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
100 mg/L

Additional information

In a 48-hour acute toxicity study, neonate Daphnia magna were exposed to the test substance at nominal concentrations of 0 (control), 4.6, 10, 22, 46, 100 mg/L under static conditions in accordance with the OECD 202 guideline and EU-method C.2. Since the analytically determined concentrations of the test substance in the test solutions were within +/- 20% of the nominal concentrations in all affected test groups, the effect concentration can be expressed relative to the nominal concentration for the evaluation of the test substance. The water pH, temperature and dissolved oxygen were within acceptable guideline specifications. Immobilization (mortality) and sublethal effects were observed daily. The 48 hour EC50 value in this acute toxicity study was determined to be >100 mg/L based on the nominal concentration of the test substance.
