Explosiveness
Administrative data
Link to relevant study record(s)
- Endpoint:
- explosiveness, other
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Study period:
- 21 August 2019
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- The regulatory position (specifically the EU Registration, Evaluation, Authorisation and Restriction of Chemicals, REACH, Regulation) with regards to explosivity is that a 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 ºC; or
– for mixtures of inorganic oxidising substances (UN Division 5.1) with organic materials, the concentration of the inorganic oxidising substance is:
– less than 15 %, by mass, if assigned to UN Packaging Group I (high hazard) or II (medium hazard)
– less than 30 %, by mass, if assigned to UN Packaging Group III (low hazard). - Principles of method if other than guideline:
- Classification of explosives has been undertaken by many scientists, and explosives have been classified with respect to their chemical nature. Chemical explosives can be divided into two groups; those that are classed as substances which are explosive and those that are explosive mixtures.
Substances that are explosive contain molecular groups which have explosive properties. Examples include:
• Nitro compounds
• Nitric Esters
• Nitramines
• Derivatives of chloric and perchloric acids
• Azides
• Acetylides
• Fulminates
• Ozinides
• Peroxides
• Nitrogen rich compounds – e.g.tetrazene. - GLP compliance:

- Conclusions:
- The substance is predicted to be not explosive
- Executive summary:
Epoxy Resin B is polymeric in nature. At the request of the client, various molecules within n=1,3 or 5 were assessed.
Based on the information and review of the structure of the substance, Epoxy Resin B, is deemed not to be potentially explosive.
The substance has an oxygen balance of < -200 in all cases and the chemical structure contains no alerts for explosive potential. On this basis, the substance is predicted to be not explosive.
