Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Start date: 02/04/2013 Completion date: 30/04/2013
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of relevant results.
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
other: visual crystallisation
Key result
Melting / freezing pt.:
-15.65 °C

Results:

Run Number 1 2

Mass of sample used (g) 12.5 12.6

Initial Freezing Temperature (°C) -15.6 -15.6

Final Freezing Temperature (°C) -15.6 -15.7

Result : -15.65°C

At freezing temperature white/creamy crystals began to form. The test was carried out measuring change in temperature against time, however no values could be derived using this method, therefore visual crystallization was used to measure the freezing point.

Conclusions:
The melting/freezing point was determined to be -15.65 °C.
Executive summary:

At freezing temperature white/creamy crystals began to form. The test was carried out measuring change in temperature against time, however no values could be derived using this method, therefore visual crystallization was used to measure the freezing point.

Description of key information

The melting/freezing point was determined to be -15.65 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-15.65 °C

Additional information
