Description of key information

Testing is not technically feasible as substance is hydrolytically unstable. Therefore, water solubility of the main decomposition product 2-ethylhexanol is used in CSA.

Key value for chemical safety assessment

Water solubility:
880 mg/L
at the temperature of:
25 °C

Additional information

Titanium tetrakis(2-ethylhexanolate) 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 2 -ethylhexanol and hydrated titanium dioxide (key study on hydrolysis OECD 111). As the rapid hydrolysis (half-life < 10 minutes) is the driving force for the fate and pathways of the substance, water solubility of 2 -ethylhexanol released in water is used as a key value in CSA (peer-reviewed secondary source Amidon et al. 1974). 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.
