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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
