Additional information

Conclusion on classification

The substance is readily biodegradable, has a log Kow of 3.5 and a water solubility of 310 mg/L

There are acute ecotoxicity data available for three trophic levels where the 72h ErC50 of 25 µg/L as observed for algae is the lowest value

There is one long term ecotoxicity result available i.e. the 72h ErC10 of 3.3 µg/L which was observed for algae.

Based on this data

The substance should be classified (CLP) as: Acute 1 with M-factor 10 because 0.01 < L(E)C50 0.1 mg/L

The substance should be classified (CLP) as: Chronic 1 with M-factor 1 because 0.001 < NOEC ≤ 0.01 mg/L
