Results and discussion
Partition coefficient
- Type:
- log Pow
- Partition coefficient:
- 2.68
Any other information on results incl. tables
The value is log Kow = 2.68±0.36, which was obtained by the HPLC estimation method6 in a modern GLP study and the ± value is the 95% confidence limit.
Applicant's summary and conclusion
- Conclusions:
- The partition coefficient (n-octane/water) of TCPP is ca. 2.68 with a 95% confidence limit as ±0.36.
