OTHER SPECIFICS:
- Name of test material (as cited in study report): Jeffcat DMDEE
- Physical state: Liquid
Melting / freezing pt.:
< -20 °C
Remarks on result:
other: Atmospheric pressure not reported; ambient conditions are anticipated.

Both measurements revealed a freezing temperature below -20°C.

Conclusions:
The freezing temperature of the 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).
