Conclusion on classification

CLP Regulation:

Aquatic acute toxicity:

The substance does meet the criteria for classification as given in Commission Regulation (EU) No 286/2011 amending for the second time Regulation (EC) No 1272/2008 for acute aquatic toxicity Category 1 due to its algae toxicity of 0.67 mg/l (Multiplying factor is 1).

Aquatic chronic toxicity:

The only long-term study available is the algal growth inhibition study, which resulted in a NOEC of 0.18 mg/L. This leads to a Aquatic Chronic Toxicity Category 2 (H411) as the substance is not readily biodegradable.

According to Figure 4.1.1. in the 2nd Amendment of Regulation (EC) No 1272/2008, for substances where adequate chronic toxicity data are only available for one or two trophic levels, the acute data for the other trophic levels have to be considered for chronic classification. As the substance is not readily biodegradable and the Daphnia EC50 is 1.87 mg/L, this results as well in a classification as Aquatic Chronic Toxicity Category 2 (H411).

DSD Regulation:

According to DSD (Directive 67/548/EEC) the substance is consequently classifiable with N, R50/53.
