Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
As this substance is highly reactive the auto-flammability of the main degradation product (ethanol) is used as a key value.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 363 °C
Additional information
There is a mechanistic reasoning to the read-across from degradation products and the analogue substances in the category "highly water reactive titanates " that this substance has no auto-flammability properties. This substance will decompose rapidly when in contact with moisture or water. The half-life based on the hydrolysis study (OECD 111) is less than 5 minutes. Complete hydrolysis will happen with no other degradation products than ethanol and titanium dioxide.
The testing is unnecessary as the self-ignition properties are related to the degradation products which are not self-igniting. In addition, the results of auto-flammability of the analogue category member (titanium tetraisopropanolate) are not presenting any self-ignition as the self-ignition temperature is > 400 deg. Celsius (Leslie S. 2010). The lowest self-ignition temperature of ethanol (CAS 64 -17 -5) was used as a key value in CSA (Groupe d’Étude de Sécurité des Industries Pétrolières et Chimiques 2008).
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).
