Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
GLP compliance:
yes
Type of method:
method to determine freezing temperature
Key result
Melting / freezing pt.:
< -50 °C
Remarks on result:
other: The atmospheric pressure was not specified in the report.

The sample incubated at 5°C was reported to be a thick, viscous gel with no solidification. The sample incubated at <-17°C was reported to be more viscous than the 5°C sample, but still not a solid. After approximately 5 hours of equilibrium at less than -50°C, the test material was tacky when touched with a spatula, but did not solidify or form crystals.

 

Description of key information

freezing temperature < -50 °C (OECD 102)
