Description of key information

Not explosive

Key value for chemical safety assessment

non explosive

Additional information

To determine, whether the substance could harbour explosive properties the following assessment is considered:

Column 2 of REACH Annex VII provides the following specific rules for adaptation of the standard information requirement for explosive properties. The study does not need to be conducted if:

• there are no chemical groups associated with explosive properties present in the molecule, or

•the substance contains chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than 200, or

•The organic substance or a homogenous mixture of organic substances contains chemical groups associated with explosive properties, but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500 °C.

ATMPoxide does not contain structural alerts as reported in Table R.7.1.-28 of the Information Requirements Guidances R7.a

Moreover, the thermal behaviour of the substance was tested by DSC from -20° to 300°C. The onset of melting is below 500°C (decomposition starts at 130°C) and the decomposition energy is below 500 J/g (ca. 66.57 J7g). Based on all the above considerations, ATMPoxide is not considered explosive and the explosive properties test does not need to be conducted.

Justification for classification or non-classification

Classification for explosive properties is not warranted under Regulation 1272/2008
