Conclusion on classification

In acute aquatic toxicity tests, the test item revealed LC₅₀/EC₅₀ values below 1 mg/L, and thus needs to be classified as hazardous to the aquatic environment in accordance with section 4.1.2.6., Annex I of Regulation 1272/2008/EC. As the test item is considered to be readily biodegradable, the relevant classification is Aquatic Acute 1 (H400).
