Materials and methods

Principles of method if other than guideline:

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 TGransport 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.

Results and discussion

Any other information on results incl. tables

For all constituents of the substance, it was assessed through expert judgement based on the evaluation of available data and the composition of the constituents are incapable of rapid decomposition with evolution of gases or release of heat.show explosive properties. It is therefore not expected that the test substance will exhibit explosive properties.

The evaluation according to both UN recommendation and REACH guidance 7.a is presented below:

Substance Name	UN Recommendation: Acceptance Procedure for Class 1 Explosives	REACH Guidance	Expert judgement
12-hydroxystearic acid (individual compounds)	Not applicable	Testing of explosive properties can be waived based on a consideration of the structure	No explosive properties

Applicant's summary and conclusion

Conclusions:

The test substance is not expected to be explosive.

Executive summary:

The chemical structure of 12 -hydroxystearic acid 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).

It was assessed through expert judgement based on the evaluation of available data and the composition of the substance that it is incapable of rapid decomposition with evolution of gases or release of heat. It is therefore not expected to exhibit explosive properties.
