Additional information

Conclusion on classification

The lowest EC50 values were all > 1 mg/L, so classification as Aquatic acute cat. 1 is not required.


The substance is intrinsically biodegradable and hydrolysis rapidly at environmental pH (half-lives <0.5 day at pH7 and <1h at pH9). Therefore, no classification for Aquatic Chronic toxicity applies.
