Applicant's summary and conclusion
- Conclusions:
- From the experimental data obtained according to the guideline A.8 in Official Journal L 383 par A and OECD Test No 107, it can be concluded that the BIBR 1048 Aminoacido sample shows a much greater affinity for n-octanol than for water at room temperature (ca. 22°C) and at pH value of the aqueous phases neutral (6.0).
Mean Tot Pow = 35.08
Mean Tot log Pow = 1.54
