Conclusion on classification

Two short-term and two long-term toxicity studies are available on the read across substances, C16-18 and C18-unsatd.TMAC and/or C12-16 ADBAC, in addition, to an algae toxicity study with the test substance, Oleyl TMAC. Based on the results from the available studies, algae have been identified to be the most sensitive species. The lowest 72 h ErC50 and lowest long-term NOEC values from the algae study with Oleyl TMAC were determined to be 0.00498 mg/L and 0.0022 mg/L (measured), respectively. Therefore, based on the available results and considering that the substance is readily biodegradable with a low bioaccumulation potential, Oleyl TMAC requires classification as Aquatic Acute 1 and Aquatic Chronic 1; H410: Very toxic to aquatic life with long-lasting effects according to Regulation 1272/2008/EC. M factors to be applied are 100 for acute and 1 for chronic toxicity.
