Description of key information

Testing is not technically feasible as substance is hydrolytically unstable. Log Kow of n-butanol released from the substance is used  in CSA, instead of any estimated value.

Key value for chemical safety assessment

Log Kow (Log Pow):
0.84
at the temperature of:
25 °C

Additional information

Titanium tetrabutanolate is hydrolytically unstable. When it comes in contact with water or moisture, a complete hydrolysis will take place with no significant reaction products other than n-butanol and hydrated titanium dioxide (OECD 111). Because of rapid hydrolysis (half-life <5 minutes), log Kow of n-butanol released in water is used as a key value in CSA (peer-reviewed secondary source, Lide 2008).
