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:
- 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: Calculation method: KOWWIN v 1.67 of the U.S. Environmental Protection Agency
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: calculation method
- Partition coefficient type:
- octanol-water
- Type:
- log Pow
- Partition coefficient:
- > 20
- Temp.:
- 20 °C
- Remarks on result:
- other: calculated
- Conclusions:
- The partition coefficient (log Pow) of the test item is > 20 calculated with the calculation method KOWWIN v 1.67 of the U.S. Environmental Protection Agency.
- Executive summary:
The test item is insoluble or only poorly soluble in water. Even using a co-solvent, the test item immediately precipitates after contact with water. Therefore a determination of the partition coefficient according to OECD TG 107 or 117 (EC 440/2008 A.8.) was not possible. The partition coefficient calculated with the software KOWWIN v 1.67 was > 20.
Reference
pH is not reported.
Description of key information

Key value for chemical safety assessment
- Log Kow (Log Pow):
- 20
- at the temperature of:
- 20 °C
Additional information
The substance is insoluble or only poorly soluble in water. Even using a co-solvent, the test item immediately precipitates after contact with water. Therefore a determination of the partition coefficient according to OECD TG 107 or 117 (EC 440/2008 A.8.) is not possible. Alternatively the partition coefficient was calculated using the software KOWWIN v 1.67 of the U.S. Environmental Protection Agency on the basis of the structural formula of the test item components.
