Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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 ethanol, 2-propanol, acetylacetone and titanium dioxide.
The properties of the target substance would lie in the hydrolysis products.

Additional information

According to hydrolysis test results, the hydrolysis rate is estimated to be within 30 minutes. The hydrolysis products have been identified to be ethanol, 2-propanol, acetylacetone and titanium dioxide.

The log Pow of 2 -propanol 0.05 at 20°C was chosen for CSA.
