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.
