Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Study well documented, test procedure in accordance with OECD107 method, meets generally accepted scientific principles, acceptable for assessment. Not GLP compliant
according to guideline
OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
GLP compliance:
Type of method:
shake-flask method to: flask method
Partition coefficient type:
Analytical method:

log Pow
Partition coefficient:
ca. -0.4
20 °C
< 4
log Pow = -0.4 at 20°C
Executive summary:

Partition coefficient n-octanol-water was determined according to OECD 107, Shake Flask Method. Concentrations of the tested material in the phases were measured using the UV-VIS Spectrophotometer. Average log Pow for the tested material was found to be -0.4 at 20°C.

Description of key information

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 -0.4 at 20°C.
