A concentration plateau could be reached over 72 hours at 30 °C with 24 hours subsequent incubation at 20 °C.

Total average concentration over three incubation times was 55.43 g/L, RSD 1.4%.

Description of key information

n-octanol solubility: 55.43 g/L at 20 °C

Key value for chemical safety assessment

Additional information

The solubility of the substance in n-octanol was determined applying similar experimental conditions as described for determination of water solubility according to EU method A.6 and OECD 105 (flask method).
