Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Data waiving:
study technically not feasible
Justification for data waiving:
Justification for type of information:
The substance is unstable in water and testing would record the results of the key degradation products.
The hydrolysis products are triethanolamine and zirconium dioxide. These organic products will have a low partition coefficient.
partition coefficient
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
weight of evidence
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
according to guideline
other: calculation
GLP compliance:
not specified
Type of method:

log Pow
Partition coefficient:
ca. -1.59
20 °C
ca. 7
The log Pow of triethanolamine is -1.59 at 20°C according to literature.

Description of key information

Data obtained from handbook.

Key value for chemical safety assessment

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

Additional information

As the target substance hydrolyzes rapidly within 30 minutes, the intrinsic properties of the target substance lie on the hydrolysis product. The log Pow of triethanolamine -1.59 at 20°C was chosen for CSA.
