Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Run Number



Mass of sample Used (g)



Initial Freezing Temp (°C)

Not applicable as no crystallization observed at the lower temperature limit of the test apparatus of -20°C

Initial Freezing Temp (°C)


Due to the nature of the sample crystallization was not observed. However flow restriction of the sample was observed at 6.4°C (run 1) and 6.5°C (run 2).

Description of key information

freezing point < -20°C (EU A.1)

Key value for chemical safety assessment
