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:
- 2010-01-11 to 2010-01-20
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. The test substance composition is adequately characterised with its purity. Therefore full validation applies.

- Version / remarks:
- 27thJuly 1995
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- Council Regulation (EC) No 440/2008 dated30 May 2008
- Qualifier:
- according to guideline
- Guideline:
- other: BS4633: Method for the Determination of Crystallizing Point.
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspected on 04th and 05th May 2009 / Signed on 1st September 2009
- Type of method:
- method to determine freezing temperature
- Specific details on test material used for the study:
- Storage condition of test material: Refrigerator (between 0 and 10°C under nitrogen)
- Key result
- Melting / freezing pt.:
- < -20 °C
- Conclusions:
- No further testing is required.
- Executive summary:
The freezing point of the test substance was measured under GLP according to BS4633 method (listed in OECD 102 / EU A1 guideline).
An aliquot was placed in a cooling bath, stirred, and the temperature was recorded at regular intervals. Two runs were performed.
No crystallisation of the test material was observed down to a temperature of 250 K (-23°C).
Reference
(detailed results and graphes are available in the study report)
The test material changes in appearance during cooling. At ca 269 K, the test material becomes viscous and at ca 266 K it becomes trouble.
Description of key information
Freezing point (exp.) < -20 °C.
No further testing is required.
Key value for chemical safety assessment
Additional information
A fully reliable study, conducted according to a recognized OECD/EC method and under GLP, is available. Therefore, it is considered as a key study. As no crystallisation was observed down to -20°C, the result is expressed as a limit value, and cannot be retained as key data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
