Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 25 April 2017- 26 April 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method. Test substance is adequately characterised. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline

- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- < -20 °C
- Atm. press.:
- 1 atm
- Decomposition:
- no
- Conclusions:
- In a pre-test, the test item was solid at – 80°C. According to Regulation (EC) No 1907/2008 annex VII, column 2 of section 7.2, the determination of the melting /freezing point does not need to be conducted below a lower limit of - 20 °C.
Therefore, no additional test was conducted and the freezing point is stated as: < - 20 °C (< 253.15 K). - Executive summary:
This study was performed in order to determine the freezing point or the freezing range of the test item according to OECD 102 and EU A1 test guideline.
In a pre-test, the test item was solid at – 80°C. According to Regulation (EC) No 1907/2008 annex VII, column 2 of section 7.2, the determination of the melting/freezing point does not need to be conducted below a lower limit of - 20 °C.
Therefore, no additional test was conducted and the freezing point is stated as: < - 20 °C (< 253.15 K).
Reference
After evaluation the following values were recorded:
Room Temperature |
3.4°C |
-21.4°C |
-80°C |
Clear, yellow coloured liquid |
liquid |
more viscous, but still liquid |
frozen |
After coming back to room temperature the test samples appeared like in the original state.
As according to REACH annex VII, column 2 of section 7.2, the determination of the melting / freezing point does not need to be conducted below a lower limit of - 20 °C; therefore no main test was performed.
Description of key information
The freezing point of test item was stated as: < - 20 °C (< 253.15 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 253.15 K
Additional information
A fully reliable experimental study, conducted according to OECD 102/ EU A1 guideline is available.
It is considered as a key study, and the result is retained as key data.
