Reference
Endpoint:
partition coefficient
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: The test has been performed following official guidelines and completely assessed the end point.
Qualifier:
according to guideline
Guideline:
OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
GLP compliance:
no
Type of method:
shake-flask method to: flask method
Partition coefficient type:
octanol-water
Analytical method:
other: UV
Type:
log Pow
Partition coefficient:
ca. -0.609
Temp.:
20 °C
Remarks on result:
other: pH not available
Conclusions:
The partition coefficient of the tested substance is logPow = - 0.6009
Executive summary:

The partition coefficient of the tested substance is logPow= - 0.6009

The result shows the clear affinity of the test item to water phase in respect to the organic phase.

Description of key information

log Kow = - 0.6009 at 20°C

Key value for chemical safety assessment

Log Kow (Log Pow):
-0.601
at the temperature of:
20 °C

Additional information

The determination of partition coefficient n-octanol-water was performed according to OECD 107, Shake Flask Method (REACH&Colours Kft).

Average log Pow for the tested material was found to be - 0.6009 at 20°C.
