After 24 hours both replicates were liquid.
After another 24 hours (at 48 hours) in the freezer the test item was
As the test item was not frozen in the
course of the preliminary test, the main test was not performed. Based
on the preliminary test freezing point of the test item is below -30 °C.
A study was conducted according to
OECD TG 102, Regulation (EC) No 440/2008 method A.1 and EPA OPPTS
830.7200 to determine the freezing point of the test. In order to check
the approximate freezing temperature 1 mL of the test item was
transferred into 2 mL cryovials. Four replicate tubes were placed in the
freezer. After 24 hours storage period two replicate tubes were removed
and the physical state of the test item was examined. The remaining
tubes were turned over and immediately put back into the freezer for
another 24 hours. Then these tubes were checked if the test item could
flow through to the cap of the tube. The test item did not freeze in the
course of the preliminary test, therefore, no main test was performed
and the freezing point of the test item was stated to be below -30 °C.
The freezing temperature of the test item
was determined to be <-30 °C.
