Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The short-term toxicity test to aquatic invertebrates (Noack_2012) performed according to EU Method C.2., OECD 202 and GLP was rated with RL=1 (reliable without restrictions) and used as a key study. Immobilisation to Daphnia magna of the test item was observed at the geometric mean measured concentration of 45.6 mg/L and greater. The EC50 (48 hours) was 44.4 (95% CL: 42.0 – 47.3 mg/L) mg/L, the NOEC after 48 hours was 35.6 mg/L and the LOEC after 48 h was 45.6 mg/L (all geometric mean measured concentration).
