The DSC-curves obtained during the five experiments are included in
attachments. In Experiment 1, two endothermic peaks between 50 °C and
100 °C were observed. The effects were most likely related to melting of
the test item. In order to investigate the effects between 50 °C and 100
°C a repeated heating cycle was applied in Experiment 2. Two exothermic
peaks between 25 °C and 75 °C were observed on cooling and endothermic
peaks again observed between 50 °C and 100 °C in the second heating
cycle. An experiment (curve 5) done at a higher heating rate showed that
the lower temperature endothermic peak was rate-dependent and thus not
related to melting. The melting temperature was determined as the
average temperature of the effects obtained from Experiment 1
(79.547°C), Experiment 2 (78.953 °C), Experiment 3 (79.712 °C) and
Experiment 4 (79.217 °C).
The melting point of FBSEE diol was tested using differential scanning
calorimetry (DSC). The melting temperature was determined as the average
temperature of the effects obtained from five experiments. The study was
conducted in accordance with EU Method A.1 and was GLP compliant;
therefore the study is considered reliable without restrictions.
