Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Type of information:
experimental study
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 107 (Partition Coefficient (n-octanol / water), Shake Flask Method)
GLP compliance:
Type of method:
flask method
Partition coefficient type:
Analytical method:
gas chromatography
Key result
log Pow
Partition coefficient:
25 °C

Evaluation of isolated components: Cyclohexanol

log Pow = 1.25

Study was performed without adjustment of pH value.

The log Kow of cyclohexanol was determined with the shake flask method and found to be 1.25.
Executive summary:

The octanol-water partition coefficient of cyclohexanol was determined with the shake flask method under non-GLP conditions in accordance with OECD Testing Guideline 107. The log Kow was found to be 1.25.

Description of key information

1.25 at 25 °C, OECD 107, BASF (1988)

Additional information

The available study on Partition Coefficient is relevant, adequate and reliable with restrictions (Klimisch 2) and its result is considered for the purpose of classification and labelling and risk assessment.

Hansch (1967) was the recommended value suggested by the LOGKOW Databank (Sangster) and it is reported as supporting data.
