Conclusion on classification

Based on available acute aquatic toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is 4.64 mg/L (EC50 for aquatic invertebrates). Based on the available acute data, the substance should not be classified for acute toxicity following Annex I, table 4.1.0a of the CLP regulation (there are no acute values <=1 mg/L).

Based on the available acute data, and the fact that the substance is readily biodegradable, the substance does not need to be classified for chronic aquatic toxicity.
