Results and discussion
Partition coefficient
- Key result
- Type:
- log Pow
- Partition coefficient:
- >= 7.68 - <= 8.15
- Temp.:
- 30 °C
- pH:
- >= 4 - <= 10
Any other information on results incl. tables
The following partition coefficients were determined for the two chromatographic peaks of the test item:
- First peak: log = 7.68.
- Second peak: log Pow = 8.15.
According to a Sponsor’s internal study, the first peak seems to correspond to the caprylyl glycol linolenate (sum of primary and secondary esters, representing about 50% of the test item), and the second peak to caprylyl glycol linoleate (representing 8.6% of the test item).
These values are the mean of three independent measurements.
Applicant's summary and conclusion
- Conclusions:
- The test substance is considered to have a partition coefficient (log Pow) in the range 7.68 – 8.15.
