Remarks:

(under the influence of flame, shock and friction.)

Results:

- Thermal sensitivity:There were no explosions observed in any of the three tests in serial 1 and serial 2, respectively. It can be reported that there is no explosive property of the test substance induced by flame.

- Mechanical sensitivity (shock):None of the six single tests showed any reaction. It can be reported that there is no explosive property of the test substance induced by shock.

- Mechanical sensitivity (friction):None of the six single tests showed any reaction. It can be reported that there is no explosive property of the test substance induced by friction.

Interpretation of results:

other: CLP criteria not met

Conclusions:

Under the test conditions it was shown that the test substance does not have any explosive properties under the influence of flame, shock and friction.

Executive summary:

A study was conducted to determine the explosive properties of the test substance 'didecyldimethylammonium chloride' (DDAC) according to EU Method A.14 (Explosive properties). The method comprised of determination of thermal sensitivity, mechanical sensitivity with respect to shock and mechanical sensitivity with respect to friction. Under the test conditions it was shown that the test substance does not have any explosive properties under the influence of flame, shock and friction.

Executive summary:

A study was conducted to determine the explosive properties of the test substance 'didecyldimethylammonium chloride' (DDAC) according to EU Method A.14 (Explosive properties). The thermal sensitivity and mechanical sensitivity (shock) were evaluated. Under the test conditions, it was shown that the test substance does not have any explosive properties under the influence of flame and shock. .

Description of key information

According to EU Method A.14, it is not necessary to carry out the test for 'Explosive properties' if the examination of the structure shows that the substance has no reactive groups which could lead to quick decomposition with the formation of gases or heat. The test substance has no such reactive groups (that indicate a rapid decomposition). Further, it was not considered to be flammable and did not react violently in a flammability test. Therefore, it was not expected to possess explosive properties.

This was further confirmed by the absence of explosive properties in two studies conducted with a powder as well as liquid forms of the test substance according to EU Method A.14 (Keipert 2001 and 2002).
