Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Values Pre-Test

Room Temperature

5.0°C

-22.0°C

-80°C

Clear, slight yellowish and slight viscose liquid

Still liquid, like at room temperature

Still liquid, bit more viscose as at room temperature

Solid, like ice
Conclusions:
In a pre-test, the test item Hatcol 1570 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. Decem-ber 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).
Executive summary:

Title of Study: Determination of the melting point of Hatcol 1570 according to OECD 102 resp. EU A.1

 

Findings and Results:

In a pre-test, the test item Hatcol 1570 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 melting point is stated as:

< - 20 °C (< 253.15 K).

Description of key information

The 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

In a pre-test, the test item Hatcol 1570 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 melting point is stated as:

< - 20 °C (< 253.15 K).
