Study period:

October 31, 2017

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: An assessment was carried out based on an examination of the functionality within the substance

Qualifier:

no guideline followed

Principles of method if other than guideline:

The functionality of Coffee, bean, roasted, ext. and its identified constituents were reviewed in order to assess potential explosiveness. Consideration was given to the roasting and extraction process of coffee, bean, roasted, ext., which can occur at elevated temperatures (typically 215-480°C), to identify any possible effects on functionality. Relevant regulation and guidance, namely the REACH Regulation (EC) No 1907/2006, the CLP Regulation (EC) No 1272/2008, and UN Recommendations on the Transport of Dangerous Goods: Manual of Tests and Criteria, 6th Ed, were used as part of a screening procedure in order to aid in the identification of elements typically associated with explosive properties.

Functional Group (Examples)*	Conclusion
C-C Unsaturation (Acetylenes, Acetylides, 1,2-dienes)	Unsaturation present but not of the type normally associated with explosive behaviour
C-Metal and N-Metal (Grignard Reagents, Organo-lithium Compounds)	Not present
Contiguous N Atoms (Azides, Aliphatic Azo Compounds, Diazonium Salts, Hydrazines	Not present
Contiguous O Atoms (Peroxides, Ozonides)	Not present
N-O (Hydroxylamines, Nitrates, Nitro Compounds, Nitroso Compounds, N-Oxides)	Not present
N-Halogen (Chloramines, Fluoroamines)	Not present
O-Halogen (Chlorates, Perchlorates)	Not present

*Taken from Table A6.1 in Appendix 6 of the UN RTDG, Manual of Tests and Criteria.

Interpretation of results:

GHS criteria not met

Conclusions:

Coffee, bean, roasted, ext. does not possess explosive properties given a lack of common structural features associated with such behaviour. The registered substance does not require classification as an explosive material according tp the criteria set in CLP Regulation (EC) No 1272/2008.

Executive summary:

An expert assessment was performed to evaluate the explosive potential of Coffee, bean, roasted, ext. by a review of the molecular structure (functionality) of the registered substance and by consideration of the roasting and extraction process of the coffee beans. Relevant guidance in the CLP Regulation (EC) No 1272/2008 and the REACH Regulation (EC) No 1907/2006 was used as part of a screening procedure to identify potential functional groups within the registered substance that could be associated with explosive behaviour. The UN Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria has outlined a number of structural motifs within a molecule structure that are indicative of explosive properties.

No functional groups, including halogens (bound to nitrogen or oxygen), nitrogen (bound to oxygen or halogens), or metals (bound to oxygen or nitrogen), were apparent in coffee, bean, roasted, ext. following analytical characterisation. The roasting process is not anticipated to introduce new functionality that might be associated with explosive behaviour. Oxygen was identified; however, this was not contained within any functional group of concern. Similarly, although C-C unsaturation was present in the substance (e.g. furans and pyridines), the functional groups involved are present in structures that are not linked to explosiveness. It can be concluded that Coffee, bean, roasted, ext. does not have functionality associated with explosive behaviour and, therefore, classification as an explosive is not required under CLP Regulation (EC) No 1272/2008.

Description of key information

It has been concluded following an expert assessment of a weight of evidence pertaining to the molecular structure and manufacture of Coffee, bean, roasted, ext., that the registered substance does not possess explosive properties. Classification as an explosive under CLP Regulation (EC) No 1272/2008 is not required.
