The bacteriotoxicity of Vestagon EP-HA 320 was determined in the Pseudomonas putida cell multiplication inhibition test according to DIN EN ISO 10712) by Hüls Infracor GmbH. Bacteria were exposed to test substance concnetrations ranging from 0.1 to 10,000 mg/L for 17 hours and the influence of the test substance on bacterial greoth was determined by light absorption. 

Key value for chemical safety assessment

EC50 for microorganisms:
10 000 mg/L
EC10 or NOEC for microorganisms:
10 000 mg/L

Additional information

The test substance did not inhibit the baterial growth of Pseudomonas putida up to a concentration of 10,000 mg/l.
