Additional information

Conclusion on classification

Short-term fish and algae toxicity studies are available on the test substance and a Daphnia study is available on the read across substance, ‘di-C16-18-satd. and C18-24-unsatd. AAEMIM-MS’. Based on the results from the available studies, algae have been identified to be the most sensitive species. The short-term 72 h ErC50 value for the test substance in algae was considered to be at >0.15 mg/L (measured) and the long-term equivalent ErC10 or NOEC values were at 0.082 or 0.06 mg/L (measured) respectively. Therefore, based on the available results and considering that the substance is not readily biodegradable, the test substance ‘di-C18-22 AAEMIM-MS’, warrants classification as Aquatic Acute 1 and Aquatic Chronic 1; H410: Very toxic to aquatic life with long-lasting effects according to the EU CLP criteria (Regulation 1272/2008/EC). M factors to be applied are 1 for acute and 1 for chronic toxicity.
