Initial Freezing Temp (°C)

Not applicable as no crystallization observed at the lower temperature limit of the test apparatus of -20°C

Initial Freezing Temp (°C)

 

Due to the nature of the sample crystallization was not observed. However flow restriction of the sample was observed at 6.4°C (run 1) and 6.5°C (run 2).

Description of key information

freezing point < -20°C (EU A.1)

Key value for chemical safety assessment
