Additional information

Conclusion on classification

The lowest L(EC50) value is the 72 -h ErC50 of 0.165 mg/L for algae.

The only available NOEC is the NOErC of 0.032 mg/L for algae.

The substance is readily biodegradable.

The log Kow = 3.55 indicating a low potential for bioaccumulation.

Based on this information, the substance is classified as Acute Category 1, M factor = 1; Chronic Category 2 according to CLP.
