Partition coefficient
Administrative data
- Endpoint:
- partition coefficient
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- As neither the HPLC method (OECD 117) or shake flask method (OECD 107), nor the slow stirring shake flask method (OECD 123) are applicable to this substance, thus the determination is based on the calculation of the Log Kow using a fragment constant methodology.

Applicant's summary and conclusion
- Conclusions:
- The log Kow of the individual compounds were estimated with EPISUITE, KOWWIN Program (v1.68), and log Kow values between 6.76 and 11.67 were obtained depending on the length of the fatty acid chains (between C14 and C24) and the number of double bonds.
- Executive summary:
The log Kow of the individual compounds were estimated with EPISUITE, KOWWIN Program (v1.68), and log Kow values between 6.76 and 11.67 were obtained depending on the length of the fatty acid chains (between C14 and C24) and the number of double bonds.
