Description of key information

The EC50/ EC10 was determined to be 2100 / 1350 mg/L (based on growth inhibition) in a 16 hour toxicity test with Pseudomonas

putida according to DIN 38412 section 8. (CCR, Cytotest Cell Research GmbH & Co. KG, 1991)

Key value for chemical safety assessment

EC50 for microorganisms:
2 100 mg/L
EC10 or NOEC for microorganisms:
1 350 mg/L

Additional information

There is one growth inhibition study with Pseudomonoas putida available for Dimethylaminoproyl methacrylamide, which is considered reliable without restriction (Klimisch score 1; CCR, Cytotest Cell Research GmbH & Co. KG, 1991).

In this static study Dimethylaminopropyl methacrylamide was tested in concentrations of 0, 0.5, 1.0, 1.5, 2.0, 2.5, 2.8, 3.1 g/L during 16 hours with pseudomonas putida according DIN 38412 L8. Under the described conditions the EC50/ EC10 was determined to be 2100 / 1350 mg/L (based on growth inhibition).
