- Executive summary:
The test item Leuco Sulphur Green 16 has no boiling point up to 500 °C at atmospheric pressure (999 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
Reference
In the temperature ranges of 50 °C to 160 °C, two endothermic effects were observed, which shows no typical melting signal.

For verification of the resultsthe test item was additionally tested according to the capillary method. There, no melting, no boiling and no change of the color of the test item were observed up to a temperature of 390 °C. Hence, the endothermic effects found in the DSC measurements cannot be assigned to melting or boiling of the test item.
In summary, the test item has no melting point and no boiling point up to a temperature of 500 °C.
Description of key information
