Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

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:
- 3/07/2002-30/09/2002
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: BS 2000: Part 15 (equivalent to ISO 3016)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- pour point
- Key result
- Melting / freezing pt.:
- < -2 °C
- Atm. press.:
- ca. 101 325 Pa
- Conclusions:
- The pour point of the test material was measured to be -2 ± 3 oC
- Executive summary:
A sample of test material was poured into a test jar which was then enclosed in a glass jacket. The sample was heated to 46 °C in a water bath set at 48 °C before being allowed to cool in air to 35 °C. The sample was transferred to a bath maintained at -1 °C to 2 °C and cooled to 10 °C, then trasferred to a bath maintained at - 18 °C to - 15 °C to maintain cooling. Starting at 10 °C and at intervals of 3 °C, the sample was tilted to a horizontal position for a period of 5 seconds, during which the sample was observed for signs of flow.
The pour point of the test material was measured to be -2 ± 3 oC

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.
