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:
- Experiment start date - 25 February 2003; Experiment end date - 27 February 2003; Study completion date - 06 May 2003.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.8 (Partition Coefficient)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- calculation method (fragments)
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- Identity: FAT 40810/A
Batch: WP 6/02
Purity: approx. 75 %
Appearance: Solid, dark brownish powder
Expiration date: 12 December 2010
Storage: At room temperature at about 20 °C - Analytical method:
- high-performance liquid chromatography
- Type:
- log Pow
- Partition coefficient:
- < -4.5
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not available
- Conclusions:
- In conclusion, the partition coefficient, log Pow, of FAT 40810/A was calculated to be <- 4.5.
- Executive summary:
Neither the HPLC-method according to OECD Guideline No. 117 nor the flask-shaking method according to OECD Guideline No. 107 were applicable for the determination of the partition coefficient of FAT 40810/A. Thus, the log Pow value for the test item was estimated from its solubility in n-octanol arid in water, respectively. The water solubility of the test item was stated to be 224 g/l. The result was used for the calculation of the partition coefficient. In conclusion, the partition coefficient, log Pow, of FAT 40810/A was calculated to be <-4.5.
