Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Acute aquatic toxicity studies are available for three trophic levels. For the long-term aquatic invertebrates study and algae study no studies are available for the substance. The assessment is based on long-term daphnia and algae studies for close structural analogue substances (CAS 92908-35-5/ 1854-26-8; CAs 68411-81-4). All effective or lethal concentrations were recalculated for 100 % active ingredient.


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
