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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Testing is not technically feasible as substance is hydrolytically unstable. Therefore, water solubility of the main decomposition product n-butanol is used in CSA.
Key value for chemical safety assessment
- Water solubility:
- 63 200 mg/L
- 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 (key study on hydrolysis OECD 111). As the rapid hydrolysis (half-life < 5 minutes) is the driving force for the fate and pathways of the substance, water solubility of n-butanol, 63.2 g/l, released in water is used as a key value in CSA (peer-reviewed data database CHemIDplus Lite cited in Nov. 2012). The non-hazardous degradation product (hydrated titanium dioxide) of the target substance is insoluble in water, and therefore not relevant to be further considered in CSA.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
