Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
partition coefficient
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Principles of method if other than guideline:
The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to Exploring QSAR, Hydrophobic, Electronic and Steric Constants states that it is an extensive compilation of published data. Each record is evaluated and the preferred value is identified for each substance. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.
GLP compliance:
not specified

other: Method not stated but result taken from a reliable peer-reviewed handbook
Partition coefficient type:
octanol-water
Analytical method:
not specified
Type:
log Pow
Partition coefficient:
-1.31
Temp.:
20 °C
Remarks on result:
other: temperature assumed

Result taken from Jow P & Hansch C, Pomona College, unpublished analysis

Conclusions:
The log kow of ethanolamine is -1.31.
Executive summary:

This information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. The log kow of ethanolamine is -1.31

Description of key information

Partition coefficient is not relevant for inorganic substances, therefore only the log Kow for the organic component of this substance is reported. The log kow of ethanolamine is -1.31.

Key value for chemical safety assessment

Log Kow (Log Pow):
-1.31
at the temperature of:
20 °C

Additional information

Partition coefficient is not relevant for inorganic substances, therefore only the log Kow for the organic component of this substance is reported.

This information is taken from a reliable peer reviewed handbook (Hansch et al 1995) and so can be considered suitable for use as the key study for this endpoint. The log kow of ethanolamine is -1.31.
