Key result
Parameter:
other: thermal stability
Remarks on result:
other: exothermal effect < 500 J/g

Two DSC-measurements in closed glass crucibles with the test item showed an endothermic effect in the temperature range 60 - 100 °C and an exothermal effect in the temperature range 100 - 170 °C with an energy of 60 J/g and 74 J/g, respectively. Above 465 °C the measurements showed a noisy signal. This is possibly caused by a build-up of pressure.

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
Üotassium hexadecyl hydrogen phosphate has no explosiv properties in the sense of the Regulation (EC) No 440/2008 method A.14.
Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 method A.14 and according to OPPTS 830.631. Two DSO-measurements in closed glass crucibles with the test item showed an endothermic effect in the temperature range 60 - 100 °C and an exothermal effect in the temperature range 100 - 170 °C with an energy of 60 J/g and 74 J/9, respectively. The heat of decomposition was below 500 J/g. Therefore the test on explosive properties was not necessary. Potassium hexadecyl hydrogen phosphate has no explosive properties in the sense of Regulation (EC) No 440/2008, method A.14 and in the sense of the EPA Product Properties Test Guideline OPPTS 830.631 6.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

Based on the structure of the molecule and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for the fourteenth time in Regulation (EU) 2020/217, the test item does not have to be classified with respect to explosiveness.
