A preliminary test was performed
to check the approximate freezing temperature of the test substance. The
test item was stored at about -20°C in a deep freezer. As the sample was
not frozen after storage of 96 hours, the freezing temperature of the
test substance is considered to be <-20°C.
The determination of the freezing
temperature with thermocouples showed no heat effect from which freezing
could be deducted. Therefore, the phase transformation was determined
Two main tests were performed to
check the approximate freezing point of the test substance. At room
temperature, the test item was clear and colourless and the agitator was
stirring. The mixtures were cooled down to about -68°C. The test item
became white and cloudy at -19°C. At -68°C, the test item was still
white and the consistency increased so the sample was a paste-like mass.
At the end of the test, the test item was not frozen.
Freezing point: <-68°C at 1013 hPa
A freezing temperature value of
<-68°C at 1013 hPa was determined for the submission substance using a
relevant test method in accordance with OECD Test Guideline 102 and in
compliance with GLP. The result is considered to be reliable.
