Additional information

PNECs are in line with the EU RAR 2005. If no justifications are provided. Data was used from MCA and SMCA together since in the environment the sodium salt disassociates rapidly due to intrinsic properties (see EU RAR 2005).

Conclusion on classification

The substance is readily biodegradble. Based on an algae toxicity EC50 value of 0.033 mg/L and an EC10 value of 0.0058 mg/L, the substance should be classified as Aquatic Acute Cat 1 and Aquatic Chronic Cat 1.

M factor acute: 10

M factor chronic: 1
