Reference
Endpoint:
partition coefficient
Type of information:
other: literature review
Adequacy of study:
weight of evidence
Study period:
2013
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: CAE is an UVCB of fatty acids and glycerides essentially. The log Kow of CAE has not been determined experimentally. A literature review was performed for each component.
Principles of method if other than guideline:
Literature review
Type:
log Pow
Partition coefficient:
> 3
Remarks on result:
other: see literature review
Details on results:
A literature review was performed for each component. (please refer to attached file). The estimated log Kow values of all components of CAE range between 3.40 and 14.1. No experimental data is available for two alkyl triols; however, their content is very low (1.8% w/w total). Therefore, the log Kow value of CAE is expected to be > 3.
Due to this high calculated octanol/water partition coefficient, CAE may have a tendency to bioaccumulate.
Conclusions:

Description of key information

As the substance CAE is a UVCB, the partition coefficient of CAE has not been determined experimentally. A literature review was performed for each component. The log Kow ranges between 3.40 and 13.1. No experimental data is available for two alkyl triols; however, their content is very low (1.8% w/w total). Therefore, the log Kow value of CAE is expected to be > 3. For the risk assessment, the value of 5 is chosen.

Key value for chemical safety assessment

Log Kow (Log Pow):
