Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Aquatic acute toxicity:

96h, LC50 (Danio rerio) > 109 mg/L (100 mg/L corrected for water content of submission substance);

96h; LC50 (Leuciscus idus) > 740 <1591 mg/L (calculated for 100% active ingredient)

48h, EC50 (Daphnia magna) > 109 mg/L (100 mg/L corrected for water content of submission substance);

72h, ErC50 (Scenedesmus subspicatus, CAS 68411-81-4) > 127.5 mg/L

72h, ErC50 (Pseudokirchneriella subcapitata, CAS 92908-35-5): 165 mg/L (recalculated for 100 % active ingredient)

Aquatic chronic toxicity:

21d, NOEC (Daphnia magna; CAS 92908-35-5) >= 70 mg/L (recalculated for 100 % active ingredient)

72h, NOEC (Scenedesmus subspicatus; CAS 68411-81-4): 16.8 mg/L

72h, EC10 (Scenedesmus subspicatus; CAS 68411-81-4): 63.5 mg/L

72h, NOEC (Pseudokirchneriella subcapitata, CAS 92908-35-5): 30 mg/L (recalculated for 100 % active ingredient)

28d, NOEC (sewage treatment plant microorganisms) >= 86.2 mg/L

Biodegradation: The substance is not readily biodegradable under the conditions of the ready biodegradability tests performed.

Partition coefficient: log Kow < 0.3 at 23 °C

Classification according to CLP 

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The acute and the chronic aquatic effect concentrations are all > 1 mg/L. Based on these results, the test substance is not classified for acute and chronic aquatic toxicity, according to Regulation (EC) No 1272/2008 (CLP), as amended for the tenth time in Regulation (EU) No 2017/776.
