Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- 2016
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- QSAR prediction
- 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:
- other: QSAR
- Partition coefficient type:
- octanol-water
- Type:
- log Pow
- Partition coefficient:
- 2.69
- Remarks on result:
- other: Temperature and pH are not determined
- Conclusions:
- The log Pow was calculated (QSAR) with KOWWIN. Due to the fact that this substance is a long chain hydrocarbon with ethoxy groups it fits only partly in the applicability domain of KOWWIN. The reason is the high amount of CH2 and ethoxy groups. Nevertheless the prediction is seen as valid and can be
used for classification and risk assessment because the KOWWIN QSAR program calculates reliable results for fatty acid esters. - Endpoint:

log Pow 2.41 - 2.69 (QSAR, KOWWIN v1.68)
Key value for chemical safety assessment
Additional information
The log Pow was calculated (QSAR) with KOWWIN. Due to the fact that this substance is a long chain hydrocarbon with ethoxy groups it fits only partly in the applicability domain of KOWWIN. The reason is the high amount of CH2 and ethoxy groups. Nevertheless the prediction is seen as valid and can be used for classification and risk assessment because the KOWWIN QSAR program calculates reliable results for fatty acid esters.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
