Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
