Additional information
Since no adverse effects on the three trophic levels (fish, daphnia, and algae) were observed up to the water solubility, no hazard is identified. Therefore, no PNECs were derived for the test item.
Conclusion on classification
Short-term toxicity to fish
96 -h LC50 > 100 mg/L (nominal); no adverse effects up to the limit of water solubility
Short-term toxicity to daphnia magna
48 -h EC50 > 100 mg/L (nominal); no adverse effects up to the limit of water solubility (based on read-across)
Toxicity to aquatic algae
72 -h EC50 and 72 -h EC10 > 100 mg/L (nominal); no adverse effects up to the limit of water solubility (based on read-across)
Long-term toxicity to fish
No adverse effects were observed up to the limit of water solubility.
Biodegradation: not readily biodegrdable
Classification, Labeling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data of the substance and the source substance are reliable and suitable for classification purposes under Regulation (EC) No. 1272/2008. The test item was determined be not readily biodegradable. In the aquatic tests conducted, the test substance or the read-across source substance showed no toxic effects on the tested species. The determined EC50 for daphnia was 100 mg/L (nominal) and for algae was 100 mg/L (nominal) (growth rate). The EC10 (growth rate) for algae was determined to be 100 mg/L (nominal). No effects up to limit of water solubility were observed in fish, resulting in a 96 h LC50 of > 100 mg/L. Based on these results, the substance is not considered to require classification for short-term (acute) and long-term (chronic) aquatic toxicity according to Regulation (EC) No 1272/2008 (CLP).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
