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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Endpoint:
- partition coefficient
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Study period:
- 2021
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: State of the art review of the partition coefficient n-octanol/water. An experimental determination of the partition coefficient n-octanol/water using OECD methods was not applicable due to the substance's properties.
- Justification for type of information:
- State of the art review of the partition coefficient n-octanol/water. An experimental determination of the partition coefficient n-octanol/water using OECD methods was not applicable due to the substance's properties.
please see attached justification below.

Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The partition coefficient of the test substances's constituents were estimated through computational methods recommended in chapter R.7a, in: Guidance on information requirements and chemical safety assessment. The calculations were performed with the program KOWWIN.
Litterature review was also performed on each of the constituents:
Pubchem data and REACH registration dossier's data were reported when available. - GLP compliance:
- no
Test material
- Reference substance name:
- Docosan-1-ol, icosan-1-ol, octadecan-1-ol and their reaction products with betaine and ethanesulphonic acid
- IUPAC Name:
- Docosan-1-ol, icosan-1-ol, octadecan-1-ol and their reaction products with betaine and ethanesulphonic acid
- Test material form:
- solid: bulk
Constituent 1
Results and discussion
Partition coefficient
- Key result
- Type:
- log Pow
- Partition coefficient:
- > -5.91 - < 21.397
- Remarks on result:
- other: pH and Temperature are not available since the partition coefficient value provided is the interval between the constituent having the lower logP and the constituent having the highest.
Applicant's summary and conclusion
- Executive summary:
None of the existing OECD test were applicable to this substance.
therefore, a calculation value based on each constituents is provided.
The expected LogP value for the substance Eicosan-1-ol, docosan-1-ol, octadecan-1-ol and their reaction products with glycine betaine and ethanesulphonic acid is >-5.9095 and <21.3966.
