Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 2018-04-11
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- Due to the low water solubility of the test item, the experimental study for log P determination is technically not feasible and therefore QSAR estimation is used to cover the endpoint. Please refer to QPRF/QMRF documentation for detailed information on model suitability.
- Qualifier:
- according to guideline
- Guideline:
- other: Guidance on information requirements and chemical safety assessment Chapter R.6: QSARs and grouping of chemicals
- Version / remarks:
- May 2008
- Principles of method if other than guideline:
- QSAR prediction using KOWWIN v1.68 of EpiSuite v4.11. QSAR calculation is based on the fragment constant methodology.
- GLP compliance:
- no
- Type of method:
- calculation method (fragments)
- Partition coefficient type:
- octanol-water
- Specific details on test material used for the study:
- SMILES: C(OC(=O)OC1=C(C=CC=C1)C(=O)OOC(=O)C1=CC=CC=C1)(C)C
- Key result
- Type:
- log Pow
- Partition coefficient:
- 3.8
- Temp.:
- 20 °C
- Remarks on result:
- other: pH not available in QSAR prediction.
- Details on results:
- see QPRF/QMRF
- Conclusions:
- The estimated log Pow = 3.8 for the test item is suggests hydrophobic properties associated with a moderate potential for adsorption and bioaccumulation.
- Executive summary:
The estimated log Pow = 3.8 for the test item suggests hydrophobic properties associated with a moderate potential for adsorption and bioaccumulation. The test item is considered to be in the applicability domain of the model and the final result is considered adequate for a regulatory conclusion.
