Description of key information
In an Bacterial growth inhibition test using Pseudomonas putida the following effect concentrations were determined:
EC10 (16 h) = 347 mg/L (nominal concentration)
EC50 (16 h) = 709 mg/L (nominal concentration)
EC90 (16 h) = 1120 mg/L (nominal concentration)
Key value for chemical safety assessment
- EC50 for microorganisms:
- 709 mg/L
- EC10 or NOEC for microorganisms:
- 347 mg/L
Additional information
The inhibitory effect of the test substance on the ceII multiplication of the bacterium Pseudomonas putida was investigated in a 16-hour static Bacterial growth inhibition test according to DIN EN Isa 10712 (February 1996). The test substance was tested in the concentration range between 39.1 and 10000 mg/L (nominal). The dilution factor was 2. The following results show the nominal concentrations of the test sample that causes an inhibition of bacterial cell multiplication after 16 h compared to the untreated control: EC10 (16 h) = 347 mg/L, EC50 (16 h) = 709 mg/L, EC90 (16 h) = 1120 mg/L. The validity criteria were fulfilled by the test.
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.
