- Lot/batch No.: 1903/2012
Key result
Melting / freezing pt.:
-0.7 °C
Remarks on result:
other: Atmospheric pressure not reported; ambient conditions are anticipated.

The first measurement revealed a freezing temperature of -0.8°C and the second measurement revealed a freezing temperature of -0.6°C.

Conclusions:
The freezing temperature of the substance was concluded to be -0.7°C under ambient conditions.

Description of key information

The freezing point of the test substance under ambient conditions was determined to -0.7°C in a GLP study according to test method EC A.1 (Younis, 2013).

Key value for chemical safety assessment
