Description of key information

The EC50 value was determined to be greater than 1000 mg/L and also the EC10 was determined to be greater than 1000 mg/L (based on active ingredient concentration).

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
1 000 mg/L

Additional information

The toxicity to microorganisms for Ureidomethacrylate 50% in water was determined in a GLP short-term respiration test according to OECD guideline 209 using domestic activated sludge. After 180 min an EC20 of > 1000 mg/L(based on active ingredient conc.) or > 2000 mg/l (nominal effect conc.) was obtained (BASF AG 2013).
