Conclusions:
Average log Pow for the tested material is found to be -0.13 at 20°C and pH = 6.32
Executive summary:

Partition coefficient n-octanol-water was determined according to OECD 107, Shake Flask Method. Concentrations of the tested material in the phases were measured using the UV-VIS Spectrophotometer. Average log Pow for the tested material was found to be -0.13 at 20°C and pH = 6.32

Description of key information
