Conclusion on classification

The environmental classification of the test substance is currently not harmonised according to the CLP Regulation (EC) 1272/2008. Based on available acute aquatic toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is 1.5 mg/L (LC50 for fish). Based on the available acute data, the substance should not be classified for acute toxicity following Annex I, table 4.1.0 a of the CLP regulation (as there are no acute values ≤ 1 mg/L).

In the algal growth inhibition study, the ErC10 for algae was 1.5 mg/L. No other long-term values are available, therefore the final classification is made according to the most stringent outcome of the available chronic and acute effect concentrations. The potential classification is made for the chronic algae data, following Annex I, table 4.1.0 b (ii) of the CLP Regulation. The resulting classification was compared with the potential classification made using the acute toxicity data for the other trophic levels, following Annex I, table 4.1.0 b (iii) of the CLP Regulation. Taking into account that the EC10 for algae is > 1 and the fact that the substance is rapidly degradable and its log Kow is < 4, the substance is not classified for chronic toxicity under the CLP regulation.

As the test substance is not classified for any physical, human, or environmental hazard categories, no PNECs were derived according to the CLP Regulation (EC) 1272/2008.
