Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 26 September 2017 to ****
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 123 (Partition Coefficient (1-Octanol / Water), Slow-Stirring Method)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- slow-stirring method
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- Physical state: Dark amber liquid
Purity: >93 % - Analytical method:
- high-performance liquid chromatography
- Key result
- Type:
- log Pow
- Partition coefficient:
- > 9.6
- Temp.:
- 25 °C
- pH:
- >= 5 - <= 9
- Remarks on result:
- other: High molecular weight component
- Key result
- Type:
- log Pow
- Partition coefficient:
- 9.4
- Temp.:
- 25 °C
- pH:
- 5
- Remarks on result:
- other: Low molecular weight component
- Key result
- Type:
- log Pow
- Partition coefficient:
- 9.7
- Temp.:
- 25 °C
- pH:
- 7
- Remarks on result:
- other: Low molecular weight component
- Key result
- Type:
- log Pow
- Partition coefficient:
- 8.9
- Temp.:
- 25 °C
- pH:
- 9
- Remarks on result:
- other: Low molecular weight component
- Conclusions:
- As a definitive solubility could not be determined for the high molecular weight component the log Pow was considered to be >9.6. For the low molecular weight component the log Pow was 9.4 at pH 5, 9.1 at pH 7 and 8.9 at pH 9. These results are an estimation and the real values are likely to be higher. It should be noted that there are two main stated constituents which are likely to have different partition coefficients with the higher molecular weight constituent likely to have the higher partition coefficient.
- Executive summary:
In a study performed to the standardised guideline OECD 105, under GLP conditions, the partition coefficient of the test substance has been determined for the high molecular weight component the log Pow to be >9.6 and for the low molecular weight component the log Pow to be 9.4 at pH 5, 9.1 at pH 7 and 8.9 at pH 9 at 25 °C, Smithers Viscient (ESG) Ltd. (2018).
