Additional information
In the non-GLP Klimisch 1 study from Holzschuh (2012) the explosive properties of DEPANOL I were analysed.
As stated in the reference (Commission Regulation (EC) No 440/2008, Annex A.14, § 1.1) “the tests need not to be performed when available thermodynamic information (e.g. heat of formation, heat of decomposition) and/or absence of certain reactive groups in the structural formula establishes beyond reasonable doubt that the substance is incapable of rapid decomposition with evolution of gases or release of heat (i.e. the material does not present any risk of explosion).”
According to the chemical structure and the list of reactive groups that could have explosive properties (Bretherick’s Handbook of Reactive Chemical Hazards, Butterworths, 4th edition) it can be excluded that DEPANOL I has explosive properties.
Furthermore the determination of the thermal stability of the test substance by DSC (Differential Scanning Calorimetry) - Figure 1a and 1b showed that between 30°C and 400°C the decomposition energy is -354 kJ/kg and thus below the limit of -500 kJ/kg given in the Regulation (EC) No 1272/2008 (CLP) of the European Parliament and of the Council of 16 December 2008 on classification, labelling and packaging of substances and mixtures, Chapter 2.1.4.3. (c).
Based on this Depanol I has non-explosive properties.
The result is considered as relevant for the furhter risk assessment.
Justification for classification or non-classification
According to the chemical structure and the list of reactive groups that could have explosive properties (Bretherick’s Handbook of Reactive Chemical Hazards, Butterworths, 4th edition) it can be excluded that DEPANOL I has explosive properties.

Based on this Depanol I has non-explosive properties.
