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:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: State of the art review of explosive properties.
Remarks:
KL2 due to RA
Justification for type of information:
Refer to the section 13 for details on the read across justification. The explosive property study with the read across substance is considered sufficient to fulfil the information requirements as further explained in the provided endpoint summary.
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.

other: Explosive under influence of flame
Remarks on result:

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:
other: not classified
Conclusions:
Based on the results of the read across study, the test substance, 'soaps, stocks, vegetable oil, acidulated' is not expected to show explosive properties.
Executive summary:

The chemical structure of the read across substance, oils, vegetable, deodorizer distillates, 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 read across substance. Further, according to the REACH regulation, although the read across 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 read across 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 read across substance will not show explosive properties. It is therefore not expected that the read across substance will exhibit explosive properties. Based on the evaluation of structure and oxygen balance of the major constituents (present >10%) and expert judgement, the read across substance is not expected to exhibit explosive properties (Meinerling, 2010). Based on the results of the read across study, the test substance, 'soaps, stocks, vegetable oil, acidulated' is not expected to show explosive properties.

Description of key information

The chemical structure of ‘Soaps, stocks, vegetable oil, acidulated’ 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

Similar to 'oils, vegetable, deodorizer distillates', ‘soaps, stocks, vegetable oil, acidulated’ does not contain any chemical groups associated with explosive properties considering the guidance provided in Section 7.1.11.3 of the REACH guidance R.7a: Endpoint-specific guidance (May 2008) and Appendix 6 of the UN recommendations. Therefore it does not require classification according to the CLP criteria (EC 1272/2008).
