Conclusion on classification

The environmental classification of the substance is currently not harmonised according to the CLP Regulation (EC) 1272/2008.

Based on the available toxicity data on the substance and two related substances, the lowest valid acute effect concentration for freshwater aquatic organisms is 44 mg/L (ErC50 value for algae) and the only available valid chronic effect concentration is 29 mg/L (ErC10 value for algae).

Based on the available data the substance should not be classified for Aquatic Acute toxicity. As the ErC10 for algae is > 1 mg/L (ErC10 = 29 mg/L; no other long-term studies are available) the substance should not be classified for chronic toxicity. When determining chronic classification based on the available acute toxicity data, the substance would not be classified either as its log Kow is < 4 and the substance can be considered rapidly degradable (based on the results of an inherent biodegradability study according to OECD guideline 302B).
