- Details on results:
- n-Octanol solubility
After stirring for 50 hours, the test solution with a nominal concentration of 1065 g/L was a clear solution without undissolved test substance. Based on this, it was concluded that the solubility of Blown rapeseed oil in n-octabol at 19.9 x 0.8°C is > 1000 g/L.
Water solubility
Information on the water solubility of the test substance is given in section 4.8. The water solubility was < 1 x 10^-3 g/L.
Applicant's summary and conclusion
- Conclusions:
- The estimation method was used for the determination of the partition coefficient of Blown rapeseed oil. The Pow and log Pow value of the test substance at 20°C was calculated from the n-octanol solubility and the water solubility to be > 1 x 10^6 and > 6, respectively.
