Results and discussion

Partition coefficient
Type:
log Pow
Partition coefficient:
ca. 1.63
Temp.:
20 °C
Remarks on result:
other: pH not available
Details on results:
Concentrations of the n-octanol phase were calculated directly from the absorbance values.
Concentration of the double distilled water phase was very low: even applying direct measurement to this phase, absorbance values were far below the lower limit of the spectrophotometer’s sensibility. Measured differences were below the error limits of the method.

Applicant's summary and conclusion

Conclusions:
Partition coefficient n-octanol-water was performed according to OECD 107, Shake Flask Method. Under the experimental conditions the Log Kow resulted equal to 1.63 at 20 °C.
Executive summary:

Partition coefficient n-octanol-water was performed according to OECD 107, Shake Flask Method. Under the experimental conditions the Log Kow resulted equal to 1.63 at 20 °C.
