cooling, no effects were observed which were due to crystallization of
the test substance.
further investigate the freezing temperature of the test substance, two
samples were stored for 19 hours at -22.0 ± 0.2 °C and -81.9 ± 1.9 °C
respectively. It was observed after storage that the test substance was
a viscous liquid (-20 °C freezer) and a very viscous liquid (-80 °C
freezer). According to this it was concluded that the melting
temperature of the test substance is < -80 °C (<
freezing point of the test substance was determined, under GLP,
according to OECD 102 / EU A1 guideline, using Differential Scanning
The substance was first cooled down to
-90°C, then re-heated. Crystallization
or melting were not observed in the experiments performed by the DSC.
Therefore a confirmatory limit test was conducted, with a subsample
placed overnight in a freezer at -20 °C and at -80 °C: the substance was
more viscous, but still liquid.
freezing temperature of test substance was then determined to be < -80
No freezing down to -80°C.
(no further testing is required)
A fully reliable experimental study, conducted according to a recognized
OECD/EC method and under GLP, is available. It is considered as a key
study. The result being expressed as a limit value, it is not retained
as key data (no "<" sign allowed in the key value box).
