Remarks on result:

other: Pressure not specified but assumed to be ambient

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.

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).

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
