Description of key information
The 48-hour EC50 was calculated to be 3.2 mg/L with 95% confidence limits of 3.1 and 8.2 mg/L. The 48-hour EC0 and also the 48-hour NOEC (highest concentration tested without toxic effects after 48 hours) of FEXO-03 was 1.3 mg/L since no immobilization was observed in the test organisms up to and including this test concentration. The 48-hour EC100 amounted to 6.6 mg/L.
Key value for chemical safety assessment

Additional information
The acute toxicity of the test item FEXO-03 to Daphnia magna was determined in a 48-hour static test according to the EU Commission Directive 92/69/EEC, Part C.2 (1992) and the OECD Guideline for Testing of Chemicals, No. 202, Part 1 (1984).
The reported biological results are based on the mean measured test item concentrations of 1.3 mg/L (dilution 1:22), 3.0 mg/L (dilution 1:10), 6.6 mg/L (dilution 1:4.6), 14 mg/L (dilution 1 :2.2), and 30 mg/L (undiluted filtrate).
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.
