Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
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

pH is not reported.

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.

Description of key information

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.
