Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No auto-flammability.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 343 °C
Additional information
There is enough evidence on the degradation products and the analogue substances in the category " highly water reactive titanates " that this substance has no auto-flammability properties. There is a mechanistic reasoning to the read-across from degradation products and the analogue substances in the category (see category and read-across justification in Annexes of the CSR). This substance is reactive to moisture and will decompose rapidly when in contact with water. Complete hydrolysis will happen with no other degradation products than n-butanol and hydrated titanium dioxide.
The testing is unnecessary as the self-ignition properties are related to the degradation product (n-butanol and hydrated titanium dioxide) which are not self-igniting. In addition, the results of auto-flammability test (EU A15) of the analogue category member (titanium tetraisopropanolate) is not presenting any self-ignition as the self-ignition temperature is > 400 deg. Celsius (Leslie S. 2010). The lowest auto-ignition T of the degradation product (n-butanol) is used as a key value in CSA. This value is obtained from peer-reviewed secondary source (CHEMSAFE 1997).
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.
