Reference
Endpoint:
explosive properties of explosives
Type of information:
other: Expert judgement based on Annex VII, section 7.11 of Column 2 of the REACH legislation
Adequacy of study:
weight of evidence
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: State of the art review of explosive properties.
Principles of method if other than guideline:
The chemical structure of individual constituents (>10%) of the test substance was examined for the presence of groups associated with explosive properties according to UN recommendations (Appendix 6 of the UN's Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria 4th ed (Revised Edition, 2003) and Section 7.1.11.3 of the REACH guidance R.7a: Endpoint-specific guidance (May 2008). Expert judgment was applied to conclude on the explosivity of the test substance.

Parameter:
other: Explosive under influence of flame
Remarks on result:
not measured/tested

Results:

1. Assessment according to UN-Recommendation:

None of the structural elements (mentioned in the table) can be found in the molecular structures of the individual components of test substance. On the contrary all groups within the molecular structure can be considered as thermodynamically stable under a wide range of conditions including exposure to flame, friction or shock.

2. Assessment according to REACH Guidance:

The test substance contains one or more groups (hydroxyl, carbonyl) that may contribute to the explosive property, however, there are no groups directly concerned with explosivity.

Furthermore, the oxygen balance for all individual components of the test substance is less than -200. Therefore, an experimental testing of the explosive properties is not necessary and a negative result can be predicted according to the above mentioned REACH Guidance.

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
Based on the evaluation of structure and oxygen balance of the major constituents (present >10%) and expert judgement, the test substance is not expected to exhibit explosive properties.
Executive summary:

The chemical structure of the test substance was examined for the presence of groups associated with explosive properties according to UN recommendations (Appendix 6 of the UN's Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria 4th ed (Revised Edition, 2003) and Section 7.1.11.3 of the REACH guidance R.7a: Endpoint-specific guidance (May 2008). None of the structural elements mentioned in the table A.6.1 of the UN's recommendation manual can be found in the molecular structures of the individual components of the test substance. Further, according to the REACH regulation, although the test substance contains one or more groups (hydroxyl, carbonyl) that may contribute to the explosive property, there are no groups directly concerned with explosivity. Furthermore, the oxygen balance for all individual components of the test substance is less than -200. Therefore, an experimental testing of the explosive properties is not necessary and a negative result can be predicted according to the REACH guidance. Hence, it was assessed through expert judgement, based on the evaluation of structure and oxygen balance of the individual constituents, that the test substance will not show explosive properties. It is therefore not expected that the test substance will exhibit explosive properties. Based on the evaluation of structure and oxygen balance of the major constituents (present >10%) and expert judgement, the test substance is not expected to exhibit explosive properties (Meinerling, 2010).

Description of key information

The chemical structure of the test substance was examined for the presence of groups associated with explosive properties according to UN recommendations (Appendix 6 of the UN's Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria 4th ed (Revised Edition, 2003) and Section 7.1.11.3 of the REACH guidance R.7a: Endpoint-specific guidance (May 2008).

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

‘Oils, vegetable, deodorizer distillates’ does not contain any chemical groups associated with explosive properties. Therefore it does not warrant a classification according to the CLP criteria (EC/1272/2008).
