Description of key information
No toxicity of 2-[(1-methylpropyl) amino]ethanol to microorganisms has been observed at the highest concentration tested i.e. 1000 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
The study was conducted to assess the effect of 2-[(1-Methylpropyl)amino]ethanol on the respiration rate of activated sludge according to OECD guideline 209 and GLP requirements (Dickinson, 2012). The nominal 2-[(1-Methylpropyl)amino]ethanol concentrations used in the study were 10, 100 and 1000 mg/L; five replicates were prepared for each concentration including the control. The no observed effect concentration (NOEC) for 2-[(1-Methylpropyl)amino]ethanol was 1000 mg/L. The EC20, EC50 and EC80 could not be calculated but these must be >1000 mg/L, the highest concentration tested. The validity criteria were fulfilled.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
