Additional information
Conclusion on classification
Short-term fish, Daphnia and algae toxicity as well as long-term Daphnia toxicity studies are available on the read across substance, C12-16 ADBAC. Based on the results from short-term tests and long-term tests, Daphnia and algae have been identified to be the most sensitive species respectively. The lowest short-term 48 h EC50 value for the test substance in Daphnia was determined to be at 0.016 mg a.i./L (nominal) and the lowest long-term NOEC value for the test substance in algae was determined to be 0.0025 mg a.i./L (nominal) respectively. Overall, based on the available results and considering that the substance is readily biodegradable with low bioaccumulation potential, C18 ADBAC requires classification as Aquatic Acute 1 and Aquatic Chronic 1; H410: Very toxic to aquatic life with long-lasting effects according to Regulation EC 1272/2008. M factors to be applied are 10 for acute and 1 for chronic toxicity.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
