Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2019-04-02 to 2019-08-22
- 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:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient - Shake Flask Method)
- Deviations:
- no
- Principles of method if other than guideline:
- Only preliminary test was conducted for water solubility.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method
- Partition coefficient type:
- octanol-water
- Analytical method:
- other: Due to the fact that the test item showed no evaluable UV activity, a quantitative determination of the water solubility via HPLC with UV detection was not possible. Only a preliminiary test was conducted. Please also refer to IUCLID Section 4.7.
- Key result
- Type:
- log Pow
- Partition coefficient:
- <= -3.66
- Temp.:
- 20 °C
- Remarks on result:
- other: pH value not reported
- Conclusions:
- For the test item a log Pow of -3.66 was determined in a study according to OECD guideline 107.
- Executive summary:
The partition coefficient of the test item at room temperature was estimated from the preliminary tests for the determination of the water solubility and the octanol solubility, according to Regulation EC No. 440/2008 method A.8, EC No. 2016/266 method A.24 and OECD Test guidelines 107 (1995) and 117 (2004). A log Pow of -3.66 was determined for the test item.
