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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- other:
- 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. - Endpoint:
- partition coefficient
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Qualifier:
- according to guideline
- Guideline:
- other: calculation
- GLP compliance:
- not specified
- Type of method:
- calculation method (fragments)
- Partition coefficient type:
- octanol-water
- Key result
- Type:
- log Pow
- Partition coefficient:
- ca. -1.59
- Temp.:
- 20 °C
- pH:
- ca. 7
- Conclusions:
- 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):
- -1.59
- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
