Description of key information
No immobilisation of Daphnia was observed at the only test concentration of 100 mg/L. Therefore, the 48-hour EC50 value was determined to be > 100 mg test item/L.
Key value for chemical safety assessment
Additional information
Acute toxicity of 2-[(1-methylpropyl)amino]ethanol to Daphnia magna has been investigated through OECD Guideline 202 and according to GLP requirements (Kuhl, 2010). The immobility of the Daphnia was determined in a static 48-hour test by visual observation after 24 and 48 hours. At the start of the test 93 % of the nominal test concentration was found (average of all test concentrations). After 48 hours test duration, 93 % of the nominal value was determined (average of all test concentrations). During the test the Daphnia were exposed to a mean of 93 % of nominal. Therefore, all reported results refer to nominal concentrations. After 48 hours of exposure no immobilisation of the test animals was observed in the control and in the only test concentration of nominal 100 mg/L. The 48-hour NOEC was determined to be >100 mg test item/L. The 48-hour EC50 value was determined to be > 100 mg test item/L. All the validity criteria were fulfilled.
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.
