EC number: 950-968-1 | CAS number: -
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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Remarks:
- The study was conducted according to an internationally recognised method, but without detailed documentation. The test substance is adequately identified. Therefore validation applies with restrictions.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 27th July 1995
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- Regulation (EC) No 440/2008
- Qualifier:
- according to guideline
- Guideline:
- other: BS4633, Method for the Determination of Crystallizing Point.
- GLP compliance:
- no
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -20 °C
- Atm. press.:
- 980 hPa
- Conclusions:
- No further testing required (< -20°C).
- Executive summary:
The freezing point of the test substance was determined according to OECD 102/EU A1 guideline using BS4633 method for the determination of crystallizing point.
An aliquot was placed in a cooling bath, and the temperature was recorded at regular intervals.
No freezing was observed down to the minimum test temperature of -20°C.
Reference
Accuracy: ± 0.5°C
Note that the sample was also kept in the freezer at -25°C. After 5 days storage, the sample was more viscous, but no crystallization was observed.
Description of key information
Freezing point < -20°C.
No further testing is required.
Key value for chemical safety assessment
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC/BS guideline, is available. Despite restrictions for lack of experimental details, it is considered as a key study.
As no freezing was observed down to -20°C, the result is expressed as a limit value, and cannot be retained as key data.
