Reference
Endpoint:
partition coefficient
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
Deviations:
yes
Remarks:
The shake flask method is impossible to use with surface-active materials (for these substances, a POW can be calculated based on the ratio from individual solubilities in water and n-octanol).
GLP compliance:
no
Type of method:
slow-stirring method
Partition coefficient type:
octanol-water
Type:
log Pow
Partition coefficient:
ca. -1.288
Temp.:
30 °C
Remarks on result:
other: no details on pH
Conclusions:
The substance was tested for partition coefficient n-octanol/water following OECD 107, modified for surface active substances. Under the experimental conditions the logKow was calculated to be -1.28 at 30°C.
Executive summary:

The substance was tested for partition coefficient n-octanol/water following OECD 107, modified for surface active substances. Under the experimental conditions the logKow was calculated to be -1.28 at 30°C.

Description of key information
