Conclusion on classification

A short-term fish and algae toxicity study each is available on the read across substance, C20-22 TMAC and short-term invertebrate toxicity study is available on the read across substance, C16 TMA-MS. In addition, a long-term daphnia toxicity studies is available on the read across substance, C16-18 and C18-unsatd. TMAC. Based on available short-term and long-term tests, Daphnia has been identified to be the most sensitive species. The lowest short-term 48 h EC50 value for the test substance in Daphnia was determined to be at 0.0223 mg a.i./L (measured) and the lowest long-term NOEC value was determined to be 0.0068 mg/L. Overall, based on the available results, C18-22 TMAC 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 10 for acute and 1 for chronic toxicity.
