study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Part I: Classification procedures, test methods and criteria relating to explosives of Class 1

Principles of method if other than guideline:

The assessment is based on an examination of the Substance and by oxygen balance calculation of the Substance.

The assessment is based on an examination of the Substance and by oxygen balance calculation of the Substance.

An analysis of the substance has been performed in accordance with section 2.1.4.2 of the CLP regulation (EC 1272/2008). The assessment has been made with reference to the structural motifs that are listed in Table A6.1 in Appendix 6 of the UN RTDG, Manual of Tests and Criteria as being indicative of explosive behaviour in organic materials, to identify the presence of any structural features commonly associated with explosive behaviour.

Functional Group	Comments/Conclusions
C-C unsaturation (acetylenes, acetylides, 1,2-dienes)	The substance contains C-C unsaturation as it is made from olefinic components. However these are double bonds rather than triple therefore do not represent the examples given for 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

 

The Substance does not contain any halogens or nitrogen linked to oxygen, and these elements are not expected to be introduced during the process, therefore it is unlikely that any constituents in the substance will contain these elements. The Substance is considered to contain C-C unsaturation however these do not represent the example chemistry given for explosive behaviour.

Additionally based on the representative structure of the Substance the calculation of the oxygen balance is determined to be -254.6. A substance is not classified as explosive when chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than -200.

Based on the information is concluded that the Substance is not an explosive.

Interpretation of results:

GHS criteria not met

Conclusions:

It is concluded that the registered substance is not explosive.

Executive summary:

An expert assessment was performed in accordance with section 2.1.4.2 of the CLP regulation (EC 1272/2008), based on an examination of the components used in the manufacture of the registered substance and the likely products of that reaction.

The Substance does not contain any halogens or nitrogen linked to oxygen, and these elements are not expected to be introduced during the process, therefore it is unlikely that any constituents in the substance will contain these elements. The Substance is considered to contain C-C unsaturation however these do not represent the example chemistry given for explosive behaviour.

Additionally based on the representative structure of the Substance the calculation of the oxygen balance is determined to be -254.6. A substance is not classified as explosive when chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than -200.

Based on the information is concluded that the Substance is not an explosive.

Description of key information

In accordance with the Column 2 adaptation in Section 7.11 of Annex VII of Regulation (EC) No 1907/2006 (REACH), it is considered justified to omit the explosiveness study based on the grounds that there are no chemical groups associated with explosive properties present in the molecule.

Key value for chemical safety assessment

Explosiveness:

non explosive

Justification for classification or non-classification

In accordance with the Column 2 adaptation in Section 7.11 of Annex VII of Regulation (EC) No 1907/2006 (REACH), it is considered justified to omit the explosiveness study based on the grounds that there are no chemical groups associated with explosive properties present in the molecule.
