Remarks on result:
other: the test item did not solidify as the temperature was decreased from ambient temperature down to -25°C
Conclusions:
The freezing temperature of the test substance was determined to be less than -25°C.

Description of key information

The freezing point was determined at normal atmospheric pressure to be less than -25°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
