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

At pH 7 and room temperature: very rapid hydrolysis into alkanol, 2-dimethylsubstitutedethanol and titanium hydroxide.

Key value for chemical safety assessment

Additional information

In a preliminary (K3,non-guideline) study at unknown temperature and pH and with several methodological uncertainties/deviations, it was shown that the test material hydrolysed rapidly into alkanol. The other parts of the substance were not followed-up. These data were not considered to be conclusive.

A new study was carried out to investigate if all equivalent alkanol and 2-dimethylsubstitutedethanol in the substance were released by hydrolysis. At pH 7 and room temperature, there was 100 % of release of alkanol equivalent (1H NMR result, after 10 min) and 82.7 to 84.1 % of release of 2-dimethylsubstitutedethanol equivalent (UPLC-MS-MS results, after 24 h). A white translucent hydrated solid precipitate was obtained, probably Ti(OH)4.
