Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

13.3 g/L (ALC)

Surface tension

72.9 mN/m (1 g/L, 20)

Flash point

Endpoint waived as the substance is a solid.

Auto flammability

Endpoint waived due to high melting point.


Flammability on contact with water: negative

Pyrophoricity: negative


Non explosive

Oxidising properties
