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:
- from 29/06/2018 to 20/07/2018
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- (EC) 440/2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -20 °C
- Atm. press.:
- ca. 1 013 hPa
- Remarks on result:
- other: the temperature range of the equipment is -20 to 150°C
- Conclusions:
- The freezing point of the test item is determined to be < -20°C at atmospheric pressure.
- Executive summary:
The freezing point of the test item was determined according to the EU Method A.1 and OECD 102, and in compliance with the GLP.
The sample is stirred gently and continuously during cooling and the temperature is measured at suitable intervals (e.g. 0.5 min.). As soon as the temperature remains constant for a few readings or crystals are observed in the sample, the temperature is recorded at the freezing point. During evaluation run the sample was held at -26°C for approximately 24 hours and an off-white paste was observed.
The freezing point of the test item was determined to be < -20°C at atmospheric pressure.
The freezing point study is classified as acceptable and satisfies the guideline requirements of the EU method A.1 and OECD 102.
Reference
