Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Partition coefficient
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 (Q)SAR model, with limited documentation / justification, but validity of model and reliability of prediction considered adequate based on a generally acknowledged source
- Justification for type of information:
- See EpiSuite report (attached).
The substance is surface active and UVCB making testing unreliable. The reported water solubility is consistent with the partition coefficient derived from modelling. - Qualifier:
- no guideline required
- Principles of method if other than guideline:
- EPI (Estimation Programs Interface) Suite estimates a range of physicochemical properties, environmental fate parameters and ecotoxicity. It has been developed by the US EPA in collaboration with Syracuse Research Corporation (SRC) and is used widely by governmental and industry organisations to support the assessment of new and existing industrial chemicals.
- GLP compliance:
- no
- Partition coefficient type:
- other: QSAR prediction
- Type:
- log Pow
- Partition coefficient:
- 2.39
- Temp.:
- 25 °C
- Remarks on result:
- other: QSAR prediction
- Conclusions:
- EpiSuite (KOWWIN v1.68) estimates Log Kow to be 2.39 at 25 °C.
Simple observations confirm that the substance is very soluble in in octanol, and when considering water solublity of ca 260 mg/l, this estimated Log Kow is clearly in the right order of magnitude. - Executive summary:
EpiSuite (KOWWIN v1.68) estimates Log Kow to be 2.39 at 25 °C.
If testing had been possible, it is likely that the UVCB substance would have a range of partition coefficients.
A figure of Log 2.4 is used for the CSR

Description of key information
EpiSuite (KOWWIN v1.68) estimates Log Kow to be 2.39 at 25 °C, although if testing had been possible, it is likely that the UVCB substance would have a range of partition coefficients.
A figure of Log 2.4 is used for the CSR
Simple observations confirm that the substance is very soluble in in octanol, and when considering water solublity of ca 260 mg/l, this estimated Log Kow is clearly in the right order of magnitude.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 2.4
- at the temperature of:
- 25 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
