Additional information

Conclusion on classification

Aquatic toxicity data are available for all three trophic levels (fish, daphnia and algae). No toxic effects were observed in any of the studies at or above the maximum solubility limit of the test substance in test medium.

As the substance is not readily biodegradable, and has a log Kow of >4, it is given the 'Safety net' classification Category Chronic 4 (H413: May cause long lasting harmful effects to aquatic life; harmonized classification).
