Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- 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:
- For detailed description of the model and its applicability, see "Any other information on materials and methods incl. tables".
- Principles of method if other than guideline:
- Calculation based on KOWWIN v1.68, Estimation Programs Interface Suite™ for Microsoft® Windows v4.10. US EPA, United States Environmental Protection Agency, Washington, DC, USA.
- GLP compliance:
- no
- Type of method:
- calculation method (fragments)
- Partition coefficient type:
- octanol-water
- Key result
- Type:
- log Pow
- Partition coefficient:
- 7.74
- Remarks on result:
- other: QSAR result, therefore no information available on T° and pH
- Details on results:
- For detailed description of the model and its applicability, see "Any other information on materials and methods incl. tables".
- Conclusions:
- The log Kow of Ethyl Palmitate is 7.74 calculated with the KOWWIN Program (v1.68), based on the fragment method. This model is validated and the substance Ethyl Palmitate fit its applicability domain.

Description of key information
The log Kow of Ethyl Palmitate is 7.74 calculated with the KOWWIN Program (v1.68), based on the fragment method. This model is validated and the substance Ethyl Palmitate fit its applicability domain.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 7.74
Additional information
No study investigating the log Kow of Ethyl Palmitate is available. The log Kow of the category members was also estimated with EPISUITE, KOWWIN Program (v1.68), and log Kow values between 7.17 and 9.70 were obtained depending on the length of the fatty acid chains (between C14 to C18) and the length of the alcool (between C2 to C4).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
