Applicant's summary and conclusion
- Conclusions:
- The octanol/water log Pow is 1.69.
- Executive summary:
Ratios of n-octanol/water of 1:1, 2:1, and 1:2 were tested. 0.2071 grams of the test substance was added to 100 mL of distilled water pre-saturated with n-octanol with those ratios. The solutions were shaken for 5 minutes, and then allowed to equilibrate for 3 hours at a temperature of 20 degrees C. The test was run in duplicate. The octanol/water log Pow is 1.69 +/- 0.02.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
