Key result
Melting / freezing pt.:
< -20 °C
Remarks on result:
other: Atmospheric pressure not reported; ambient conditions are anticipated.
The freezing temperature of the test substance was concluded to be below -20 °C under ambient conditions.

Description of key information

The freezing point of the test substance under ambient conditions was determined to be below -20°C in a GLP study according to test method EC A.1 (Younis, 2011).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C

Additional information

The value used for the CSA is -20 °C, although the results of the test show an unbounded value (<-20 °C)
