Additional information
Conclusion on classification
Based on the available data, the test
substance has to be classified as Aquatic Acute 1 (H400, M-factor: 1)
and Aquatic Chronic 2 (H411, M-factor: 1) according to Regulation (EC)
No 1272/2008 (CLP) as amended for the ninth time in regulation (EU) No
2016/1179.
Overview of results used for Classification and Labelling:
The EC50 value of 0.54 mg/L in P. subcapitata (growth inhibition
test) was used for the determination of the acute toxicity. Based on
this value, the substance has to be classified as Aquatic Acute 1 (EC50
< 1 mg/L) with an M-factor of 1 (0.1 < EC50≤1).
The EC10 value of 0.41 mg/L in P. subcapitata (growth inhibition test)
was also used for the determination of the chronic toxicity. Based on
this value, the substance has to be classified as Aquatic Chronic 2.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
