Applicant's summary and conclusion

Conclusions:
The partition coefficients obtained using the Estimation method and the Calculation are in agreement. Because the Calculation method is not validated at such high values, the result from the Estimation method is reported:
Log Pow of the substance is > 6 at 20.0 ± 0.5°C.
Executive summary:

The partition coefficients obtained using the Estimation method and the Calculation are in agreement. Because the Calculation method is not validated at such high values, the result from the Estimation method is reported:

Log Pow of the substance is > 6 at 20.0 ± 0.5°C.
