Description of key information

Tetrabutan, dest. is not toxic to bacteria, as tested in an oxygen consumption test with Pseudomonas putida. The EC10 > 2.0 mL/L.

Key value for chemical safety assessment

Additional information

Tetrabutan, dest. potential toxicity towards microorganisms was tested in an oxygen consumption test using Pseudomonas putida. As the test substance is only poorly soluble in water, an emulsifier was used to obtain homogenously dispersed test substance preparations of 0.1, 0.5, 1.0 and 2.0 mL/L. No effects of these concentrations of Tetrabutan, dest. on the oxygen consumption of Pseudomonas putida after 5.25 hours of exposure were recorded. Thus, the EC10 > 2.0 mL/L.
