Conclusion on classification

Acute aquatic toxicity data is available for algae, invertebrates and fish. Long-term toxicity data is only available for algae (NOErC >> 1 mg/L). The lowest EC50 was found for algal growth: 76.3 mg/L. However, this value is not considered completely reliable since thes study was not conducted in a modified version for coloured test items. Therefore, based on the results for the structural analogue substance (conducted with a modified OECD 201 study), the substance is not considered to cause relevant algicidal effects up to 100 mg/L (72 -h ErC50 > 100 mg/L). The substance is not readily biodegradable. Based on the results, the substance is not classified in accordance with Regulation 1272/2008.
