Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 most hazardous decomposition product isopropyl alcohol (IPA) is used in CSA.
Key value for chemical safety assessment
- Water solubility:
- 1 000 000 mg/L
- at the temperature of:
- 25 °C
Additional information
This substance is hydrolytically unstable (half-life < 10 minutes; OECD 111). When it comes in contact with water or moisture a complete hydrolysis will take place with no significant reaction products other than isopropyl alcohol and ethyl acetoacetate and insoluble hydrated titanium oxides. Because of rapid hydrolysis, the CSA concentrates on the most hazardous degradation product which is isopropyl alcohol. As the rapid hydrolysis (half-life less than 10 minutes) is the driving force for the fate and pathways of the substance, water solubility of isopropyl alcohol released in water is used as a key value in CSA (see section 9 & 10 of CSR). Value is obtained from peer-reviewed secondary source (Riddick et al. 1986). Titanium dioxide released from the target substance is non-hazardous and insoluble in water, and therefore not relevant for 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.
