Applicant's summary and conclusion
- Conclusions:
- The shake flask method at pH 4 and pH 7 was applied for the determination of the partition coefficient (Pow) of Phenyl Phosphonic Acid.
pH 4: The Pow value of the test item was 3.7 10-3. It corresponds with a log Pow value of -2.4.
pH 7: The Pow value of the test item was < 4.6 10-4. It corresponds with a log Pow value of < -3.3.
