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:
- 18 September 2017 to 10 October 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Black viscous liquid
- Key result
- Decomposition:
- no
- Remarks on result:
- not determinable
- Remarks:
- no endothermic peak was observed below ambient temperature (substance is a liquid at ambient temperture)
- Conclusions:
- No melting/freezing point could be found for the substance
- Executive summary:
In a test investigating the melting/freezing point of the substance using differential scanning calometry, no freezing of the substance was seen when temperatures were lowered from ambient to -100°C.

Additional information
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.
