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:
- 19-21 March 2018
- 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.

- Conclusions:
- In a pre-test, the test item was still unfrozen and liquid at – 20 °C.
At -80 °C the test item was frozen. According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PAR-LIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (last amended by Commission Reg-ulation (EU) 2016/2235 of 12 December 2016), 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 / melting point is stated as: < - 20 °C (< 253.15 K). - Executive summary:
This study was performed in order to determine the freezing point or the melting range of the test item according OECD 102 resp. EU A.1.
In a pre-test, the test item was still unfrozen and liquid at – 20 °C.
At -80 °C the test item was frozen. According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PAR-LIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (last amended by Commission Reg-ulation (EU) 2016/2235 of 12 December 2016), 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 / melting point is stated as: < - 20 °C (< 253.15 K).
Reference
After evaluation the following values were recorded:
Table: Values Pre-Test
Room Temperature |
4.6°C |
-18.9°C |
-20.1°C |
-80°C |
Dark yellow, low viscous liquid |
Still liquid |
Still liquid, just a bit more viscous and slower flowable |
Still liquid, just a bit more viscous and slower flowable |
Solid, like ice |
The Pre-Test at -20.1°C has been done in an extra Pre-test.
After performance of the pre-test, the sponsor was consulted. As according to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (last amended by Commission Regulation (EU) 2016/2235 of 12 December 2016), 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
In a pre-test, the test item was still unfrozen and liquid at – 20 °C.
At -80 °C the test item was frozen. According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (last amended by Commission Regulation (EU) 2016/2235 of 12 December 2016), 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 / melting point is stated as: < - 20 °C (< 253.15 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
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.
