Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Dynamic viscosity is 39 mPa s (dynamic) at 25 °C (manufacturer's in-house method: DKTM-112.1).
Key value for chemical safety assessment
- Viscosity:
- 39 mPa · s (dynamic)
- at the temperature of:
- 20 °C
Additional information
Key value was determined with capillary method by using manufacturer's in-house method DKTM-112 -1.
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 2 -methylpropanol, ethyl acetoacetate and insoluble hydrated titanium oxides. Because of rapid hydrolysis, the CSA concentrates on the most hazardous degradation product which is 2 -methylpropanol.
As the hydrolysis is the driving force for the fate and pathways of the substance, viscosity of 2 -methylpropanol; 4.312 mPas @ 25 deg. C released in water is used as a key value in exposure assessment when relevant ( reliable handbook value; Lide 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
