Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 15 January 2016 to 07 December 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- -18 °C
- Remarks on result:
- other: Glass transition
- Conclusions:
- Under the conditions of this study, no melting temperature was detected, but a glass transition was observed at -18 °C (mean of -17.8 and -17.6 °C).
- Executive summary:
The melting/ freezing point of the test material was investigated in accordance with the standardised guideline OECD 102, under GLP conditions.
The experiment was performed using a differential scanning calorimeter, the test material was a liquid so the test was started at - 60 °C held isothermally for 15 minutes, then heated at 5 °C/min to 20 °C and then 10 °C/min to 400 °C. Two determinations using 5.47 and 6.41 mg were made.
Under the conditions of this study, no melting temperature was detected, but a glass transition was observed at -18 °C (mean of -17.8 and -17.6 °C).
Reference
- Two determinations using 5.47 and 6.41 mg were made.
- No melting temperature was detected, but a glass transition was observed at -18 °C (mean of -17.8 and -17.6 °C).

Key value for chemical safety assessment
Additional information
The melting/ freezing point of the test material was investigated in accordance with the standardised guideline OECD 102, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
