partition coefficient
Data waiving:
study technically not feasible
Justification for data waiving:
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.

Partition coefficient (log value) of 2-propanol is 0.05 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 2 -propanol 0.05 at 20°C was chosen for CSA.
