Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
< -20 °C

Two DSC measurements were performed, during the measurement no melting point could be detected.

In the pre-test for melting point the test substance was still liquid at -20.5 °C and was frozen at -80 °C.

According toREGULATION (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 melting point is stated as:

<- 20 °C (< 253.15 K).

Conclusions:
The freezing point is stated as: < - 20 °C (< 253.15 K).

Description of key information

The melting/freezing point was tested according to the OECD Guideline 102.

The freezing point is stated as: < - 20 °C (< 253.15 K).

Key value for chemical safety assessment
