Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
