Description of key information
Based on the six determined single log Pow values, the log Pow value was calculated to be 0.62 (standard deviation: 0.41 log units). Assuming that the test substance fraction that is not dissolved in water is completely dissolved in the octanol phase (worst case estimation), a log Pow value of 1.94 is obtained for Olaflur (standard deviation: 0.29 log units).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 1.94
- at the temperature of:
- 20 °C
Additional information
The log Pow of Olaflur was investigated by shaking the substance in a suspension of a water saturated n-octanol phase and a n-octanol saturated water phase, and the subsequent measurement of the concentrations of the test substance in both phases. This method is applicable for substances with a log Pow between -2 and 4. The log Pow of Olaflur was determined in replicate for three different ratios of n-octanol and water. The six determined log Pow values do not fall within a range of 0.3 but 0.5 units. Therefore, the test did not pass the validity criterion. However, the test was difficult to evaluate, since a micellous layer was formed at the interface between octanol and water.
Assuming that the test substance fraction that is not dissolved in water is completely dissolved in the octanol phase (worst case estimation), i.e. ignoring the micellous layer, a log Pow value of 1.94 results (standard deviation: 0.29 log units).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
