Applicant's summary and conclusion

Conclusions:
The shake flask method at pH 7 and pH 11 was applied for the determination of the partition coefficient (Pow) of t-Butyldiethanolamine.
pH 7: The Pow value of the test item was 2.5 x 10-2 corresponding to a log Pow value of -1.6.
pH 11: The Pow value of the test item was 1.4 x 100 corresponding to a log Pow value of 0.1.
