Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
For manufacturing equipment design the viscosity of aluminium tri-sec-butanolate has been determined in the temperature range of 0 - 100 °C (calibration range 0 - 80 °C). The dynamic viscosity of the substance was determined by a rotational viscosimeter using an MK 20 cone, applying a constant shear rate (d gamma/dt) of 100 per second. The dynamic viscosity of aluminium tri-sec-butanolate at 20 °C was found being 2660 mPa*s, and 791 mPa*s at 40 °C, respectively.
However, the viscosity of liquids according to REACH Guidance 7a,
section 7.1.18 may be relevant for two reasons:
- penetration of fluids into soil and groundwater and
- aspiration hazards in humans resulting potentially in pneumonitis.
As aluminium tri-secondary-butylate is hydrolytically unstable, reacting
directly with moisture in air or any protic solvent such as water to
form aluminium hydroxides and 2-butanol, the use of the viscosity data,
determined for the purpose of handling the substance in dry atmosphere
under inert gas (as in production), is of no use to assess behaviour of
the substance in the environment or for assessment of potential
pneumonitis.
Key value for chemical safety assessment
Additional information
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.
