- The drop point is the temperature at which the first drop of sample falls from the cup under the specified conditions of the test.The Drop Point Method is an alternative to melting point and is used when due to the complex nature of the substance melting occurs over a wide range of temperatures. This end point effectively shows when the material would start to flow – i.e. behave as a liquid rather than a solid. Drop points are measured routinely and averages over several batches are given for lanolin alcohols.
The apparatus is filled with the sample and the temperature is raised until the first drop of sample falls and is detected photoelectrically within the FP83HT measuring cell. - GLP compliance:

Applicant's summary and conclusion
- Conclusions:
- No melting point was determined. Multiple glass transitions of the test item were observed in the range of -50 °C (223K) and 50 °C (323K)
- Executive summary:
The melting point of the test material was determined using differential scanning calorimetry (DSC). The method was designed to be compatible with EU Method A.1., OECD 102 and EPA OPPTS 830.7200.
A preliminary test was performed using a thermogravimetric analyser. 3.24 mg of the test item was heated at a rate of 20 °C/minute to 429 °C. At this point 70 % weight loss of the test item was observed. After the experiment, the sample was cooled and equilibrated at 75 °C and the consistency of the test item was determined.
Two experiments were performed during the main test. The differential scanning calorimetry (DSC) curve obtained with Experiment 1. During cooling, multiple glass transitions between 20°C and -60°C were found. During heating multiple glass transitions were observed between -50°C and 50°C followed by an endothermic effect starting at 175°C. The endothermic effect was probably obtained due to reaction and/or decomposition of the test item. After the experiment, an orange molten residue remained in the sample container (original colour: yellow). The change of the colour indicated reaction and/or decomposition of the test item. To investigate the multiple glass transitions between -50°C and 50°C, a repeated heating cycle was applied in Experiment 2. The value of the first and second cooling/heating cycles were similar to what was found in Experiment 1. This demonstrated that glass transition of the test item was the reason for these effect. Since the test item is a mixture, the glass transition was obtained from the temperature of start of the first effect (-50 °C) and of the last effect (50 °C).
No melting point was determined. Multiple glass transitions of the test item were observed in the range of -50°C (223 °K) and 50°C (323 °K)
