Endpoint:
partition coefficient
Data waiving:
study technically not feasible
Justification for data waiving:
other:
Justification for type of information:
According to hydrolysis test results, the hydrolysis rate is estimated to be within 30 minutes. The hydrolysis products have been identified to be 2-propanol, octyl alcohol, octyl phosphate and titanium dioxide.
The properties of the target substance would lie in the hydrolysis products.

Description of key information

Data obtained from handbook.

Key value for chemical safety assessment

Log Kow (Log Pow):
0.05
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 2 -propanol 0.05 at 20°C was chosen for CSA.
