Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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


96 h, LC50 (Danio rerio): >0.64 mg/L (initial measured concentration)


48 h, EC50 (Daphnia magna): >0.598 mg/L (initial measured concentration)


72 h, ErC50 (Pseudokirchneriella subcapitata): >0.5 mg/L (initial measured concentration)


 


 Aquatic chronic toxicity


72 h, NOEC (Pseudokirchneriella subcapitata): ≥0.5 mg/L (initial measured concentration)


35 d, NOEC (Danio rerio): 64.5 µg/L (mean measured concentration)


21 d, NOEC (Daphnia magna): ≥0.112 mg/L (mean measured concentration)


 


Biodegradation: not readily biodegradable: 5 % after 28 days (% degradation O2 consumption, OECD 301 B)


Partition coefficient: log Kow = 7.2 at 25 °C


 


Classification according to CLP


The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test substance was found to not be readily biodegradable under the test conditions. The most sensitive test for the aquatic compartment was the long-term toxicity test to fish. This study revealed a 35 d NOEC of 64.5 µg/L. No effects up to the limit test concentration in the short-term aquatic tests was obsered. Based on these results, the substance is not classified as short-term (acute) aquatic toxicity but is classified as long-term (chronic) aquatic toxicity Category 1 according to Regulation (EC) No 1272/2008 (CLP), as amended for the eighteenth time in Commission Regulation (EU) 2022/692.
