Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- The test substance exhibits a very low water solubility (<1.7 µg/L at 20°C). Therefore, bioavailability to aquatic organisms is strongly limited.

- All available acute tests for the test substance markedly show that no toxic effects occur up to the limit of solubility:

In a 96-h acute toxicity study of the test item to zebra-fish (Brachydanio rerio) under static conditions the NOEC and LC50 was estimated to be higher than 100 mg/L.

The 48-hr-EC50 of the test item to Daphnia magna under static conditions was determined to be > 100 mg/L (nominal loading rate of undiluted filtrate).

In a 72 hour acute toxicity study of the test item to cultures of Scenedesmus subspicatus the NOEbC and EbC50 values based on biomass were 100 and > 100 mg/L, respectively (based on nominal loading rate of undiluted filtrate).

In a 3-hr acute toxicity study sewage sludge micro-organisms were exposed to the test item at nominal concentrations of 100 mg/L in accordance with OECD 209. The IC50 value based on respiration rate was > 100 mg/L after a 3 h contact time.
