- Executive summary:
The melting point of the test item was determined by DSC measurement according to OECD 102. The test item had a melting range of 32 - 38 °C.
Reference
Three DSC measurements with a heating rate of 10 K/min showed an endothermal effect (melting) in the temperature range 20 - 125 °C. The onset temperature was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline.
The test item had a melting range of 32 - 38 °C. The results of the DSC measurement are summarised in Table 1.
