melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
comparable to guideline study
equivalent or similar to guideline
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
Type of method:
method to determine freezing temperature
Melting / freezing pt.:
< -25 °C
Remarks on result:
other: The test substance clearly flows under its own weight at -25°C.
The freezing point of the test substance is less than -25°C
Executive summary:

The freezing point of the test substance was determined by observing the flow characteristic of the test substance at -25°C. A small amount of the test substance was placed in the bottom of a jar and cooled to -40°C. The jar was then placed on its side in a -25°C chamber for three days. Observations were made before and after the three-day period. The freezing point of the test substance is less than -25°C.

Description of key information

Equivalent to OECD Guideline 102

The freezing point is less than -25ºC

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
