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:
- 10 August 2018 to 07 September 2018
- 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
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method to determine freezing temperature
- Remarks:
- crystallising point method
- Key result
- Melting / freezing pt.:
- < -20 °C
- Remarks on result:
- other: no information on atm pressure. Assume the study was performed at standard atmospheric pressure.
- Conclusions:
- The freezing point of the test material was determined to be less than -20 °C (<253 K).
- Executive summary:
The melting point/ freezing point of the test material was investigated in a study which was conducted in accordance with the standardised guidelines OECD 102 and EU Method A.1, under GLP conditions, following the crystallising point method.
Under the conditions of the test the freezing point of the test material was determined to be less than -20 °C (< 253 K).
Reference
As no plateau in the time-temperature curve could be seen, the freezing point was determined visually.
The test material remained a mobile liquid during cooling.
Description of key information
The freezing point of the test material was determined to be less than -20 °C (<253 K).
Key value for chemical safety assessment
Additional information
The melting point/ freezing point of the test material was investigated in a study which was conducted in accordance with the standardised guidelines OECD 102 and EU Method A.1, under GLP conditions, following the crystallising point method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Under the conditions of the test the freezing point of the test material was determined to be less than -20 °C (< 253 K).
