- Executive summary:
An experimental study, conducted in accordance with conditions recommended in OECD guideline was performed. According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation 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).

Final Result
In a pre-test, the test substance was still liquid at - 20.1 °C and frozen at - 80 °C.
According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation 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).
Description of key information
Freezing/melting point is stated as:< - 20 °C (< 253.15 K).
Key value for chemical safety assessment
Additional information
An experimental study, conducted in accordance with conditions recommended in OECD guideline was perfomed. This study is considered as a key study. The result is retained as key data. In a pre-test, the test substance was still liquid at - 20.1 °C and frozen at - 80 °C.
According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation 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).
