Description of key information

No impact sensitivity of isononyl benzoate was observed.
No thermal sensitivity of isononyl benzoate induced by heating under defined confinement was observed.
Therefore, the test item isononyl benzoate has no explosive properties according to the definition in the EEC-directive 92/69/EEC, method A.14.

Key value for chemical safety assessment

Additional information

The testing of explosive properties according to EU Method A.14 (Explosive properties) consists of three parts: mechanical shock sensitivity, mechanical friction sensitivity and thermal sensitivity. As the test item is a liquid, the test on mechanical friction sensitivity was not performed.

Mechanical shock sensitivity: none of the six single tests with an impact energy of 40 J showed any sparking or exploding (smoke observed in 5 of 6 trials, not assessed as positive effect in accordance with EEC directive.

No impact sensitivity of isononyl benzoate was observed.

Thermal sensitivity: after 57 - 60 sec., in all single tests the start of a weak reaction was observed by colouring the gas flames orange and by emission of test substance out of the orifice which was ignited and produced flames of about 130 cm ( 6 mm orifice) and 180 cm ( 2 mm orifice). After a duration of 45 - 63 sec. the reaction was finished and no further effects were observed. In all cases, the tubes were unchanged.

No thermal sensitivity of isononyl benzoate induced by heating under defined confinement was observed.

Therefore, the test item isononyl benzoate has no explosive properties according to the definition in the EEC-directive 92/69/EEC, method A.14.
