Description of key information

There was no freezing point evident on the cooling curve or melting point evident on the heating curve. The absence of a freezing or melting point could be attributed to a freeze point below -90°C, the instrument lower detection limit or the sample maybe amorphous whereby the viscosity increases slowly but the material does not crystallize.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-90 °C

Additional information

In accordance with Column 2 adaptation statement of REACH Annex VII, Information requirement section 7.2, this study does not need to be conducted below a lower limit of -20 °C.

There was no freezing point evident on the cooling curve or melting point evident on the heating curve. The absence of a freezing or melting point could be attributed to a freeze point below -90°C, the instrument lower detection limit or the sample maybe amorphous whereby the viscosity increases slowly but the material does not crystallize. So -90°C was set as a value for the CSA.
