Reference

Reference 1

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.

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.
