Additional information

The PNECs aqua were derived from the most sensitive test for the aquatic compartment, the short-term toxicity to fish. For other compartments, the PNECs are based on equilibrium partitioning.

Conclusion on classification

The short-term LC50 or EC50 values are 0.3 mg/L for fish, 2.21 mg/L for daphnia and 8.2 mg/L for algae.

In addition, the substance is readily biodegradable, and has a log Kow of 2.57.

According to CLP (Directive 1272/2008/EC), the aquatic hazard of substance is classified as Acute Category 1.
