Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

No toxic effects occur in the range of water solubility.

- The test substance exhibits a very low water solubility (< 0.005 mg/L at 20°C). Therefore, bioavailability to aquatic organisms is strongly limited.

- All available tests (acute and chronic) for the test substance clearly show that toxic effects only occur far above the limit of water solubility.

  • Danio rerio LC50(96h) > 67 mg/L (OECD 203)
  • Daphnia magna EC50(48h) at a nominal concentration of 100 mg/L WAF (water accommodated fraction) > 100 mg/L (OECD 202)
  • Scenedesmus subspicatus EC50(72h) > 100 mg/L (OECD 201)
  • Daphnia magna NOEC >= 10 mg/L (NOEC = WAF of a loading rate of 10 mg/L; OECD 211)

- Activated sludge was not inhibited by the test substance: IC50 > 100 mg/L (OECD 209).
