Sample Observations

 

Temperature
(°C)

Sample Appearance

4

Top of Test Item removed, mobile when touched with spatula, i.e. not frozen

-20

Top of Test Item removed, hardened compared to 4 °C but still pliable when touched with spatula, i.e. not frozen

-80

Top of Test Item removed, hardened compared to -20 °C but still pliable when touched with spatula, i.e. not frozen

 

Conclusions:
The freezing point of the test substance has been determined to be < 20 °C.
Executive summary:

In a study performed to the standardised guideline EU Test Method A.1 under GLP conditions, the freezing point of the test substance has been determined to be < 20 °C.
