Additional information
The acute toxicity of FAT 41029/A to Daphnia magna (Immobilisation Test) was performed according to OECD 202, Part 1, and 92/69/EEC, Annex L 383 A, C.2. under GLP compliance. The water temperature was maintained at 20.0 - 20.7 °C throughout the exposure period in all test vessels. The oxygen content was in the range of 97 - 98 % during the test and the pH ranged from 7.8 to 7.9. The nominal concentrations of FAT 41029/A were 4.3, 9.4, 21, 45 and 100 mg/L and a blank control without test item. The test samples were analysed for FAT 41029/A. During the test no immobilisation of the daphnia was observed in the test solutions up to the highest test concentration. Therefore, the EC0 value after 48 hours was determined to be the saturation concentration of the test substance in the test medium (corresponding to 100 mg/l nominal, <0.1 mg/l actual concentration). The 48 h EC50 of test item to Daphnia magna was greater than saturation concentration ( > 100 mg/l nominal, <0.1 mg/l actual concentration).
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).
