Partition coefficient
Administrative data
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15 Nov 2011 – 13 Jan 2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP study according to EU and OECD methods, deficiency: substance was found to be surface active (but this is not a desired property of the substance) thus the applicability of the shake-flask method can be questioned

Definitive test
The mean peak areas obtained for the standard, stock and sample
solutions were used to calculate the actual concentrations in the
solutions. No test substance was detected in the organic phase and
aqueous phase blank matrix, respectively.
The total weights (mg) and analysed concentration (mg/L) of the respective phases are shown in the following table:
