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:
- 23 January - 25 March, 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study

- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP compliance programme (inspected on 05 February 2014 / signed on 07 October 2015
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- -15 °C
- Executive summary:
The freezing point of the test item was determined under GLP according to OECD 102 / EU A1 guideline, freezing point method. Two runs were performed.
A consistent freezing point value for test item is -15.0 °C (mean of the two replicates -15.0 and -15.0 °C) as indicated by a plateau region in the cooling curve at this temperature.
The freezing temperature of the test item has been determined to be -15 °C.
Reference
A consistent freezing point value for test item is -15.0 °C (mean of the two replicates -15.0 and -15.0°C) as indicated by a plateau region in the cooling curve at this temperature.
Description of key information
Freezing (i.e. liquid-solid transition) occurs at the temperature of -15°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -15 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EU method, is available. It is considered as a key study. The result is retained as key data.
