Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Study period:
- 18 November 2008 - 18 December 2008
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- Due to the properties of the test material, the partition coefficient could only be estimated in silico. This approach is considered fully acceptable.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The estimation of the partition coefficient was performed by a fragment constant methodology using the specialised chemical estimation software, KOWWIN, version 1.67, 2000 US. Environmental Protection Agency.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: In silico: Fragment constant methodology
- Partition coefficient type:
- other: Estimated using the specialised chemical estimation software KOWWIN
- Analytical method:
- other: Not applicable
- Key result
- Type:
- log Pow
- Partition coefficient:
- > 6.78 - < 9.23
- Temp.:
- 20 °C
- pH:
- 7
- Details on results:
- Using the software, the test material was estimated to have a log10 Pow range of 6.78 to 9.23.
- Conclusions:
- The partition coefficient was estimated by a fragment constant methodology using the specialised chemical estimation software, KOWWIN, version 1.67, 2000 US. Environmental Protection Agency. The result for the test material was log10 Pow range of 6.78 to 9.23.
- Executive summary:
The partition coefficient was estimated by a fragment constant methodology using the specialised chemical estimation software, KOWWIN, version 1.67, 2000 US. Environmental Protection Agency. The result for the test material was log10 Pow range of 6.78 to 9.23.
