Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- 3.5
- Temp.:
- 35 °C
- pH:
- 7
- Details on results:
- Testing was performed at 35°C (column temperature), however the values can be considered to represent the values at an unspecified, probably ambient temperature since no mention is made in the guidelines of the temperature at which the tabulated reference substances log Kow values were determined. Partition coefficients of the test and reference substances are assumed to vary with temperature in the same way.
Applicant's summary and conclusion
- Conclusions:
- The chromatograms of Decenal-4-trans show one peak at an average retention time of 5.99 minutes, corresponding to a partition coefficient (log value) of 3,5. Therefore the Partition Coefficient n-octanol/water of Decenal-4-trans is: Log Pow =3.5
