1. Elements that are associated with explosive properties (Appendix 6,
UN Recommendations on the Transport of Dangerous Goods: Manual of Tests
and Criteria, 6th Ed.).
assessment was undertaken to determine the explosive potential of 2-(2
-methylpropoxy)ethanol and its raw materials based on their molecular
structure (functionality) and a review of available literature and
experimental data. A number of structural motifs can be linked to
explosive behaviour in organic material, as identified in Appendix 6, UN
Recommendations on the Transport of Dangerous Goods: Manual of Tests and
Criteria, 6th Ed. The REACH Regulation (EC) No. 1907/2006, Section 7.11
and CLP Regulation (EC) No. 1272/2008, Section 126.96.36.199 were referred to
in order to implement a screening procedure. Structural features
commonly associated with explosive behaviour were not identified in 2-(2
-methylpropoxy)ethanol and, therefore, the registration substance is not
believed to be explosive. The raw components did not contain halogens,
nitrogen, or metals, and these elements were not present in the final
product. In addition, oxygen was identified but this was not contained
within a chemical group that is considered to be linked with
explosiveness. Hazard classification of 2-(2-methylpropoxy)ethanol is
subsequently not required and further testing is not necessary (Column
II of REACH Annex VII).
expert assessment was undertaken to review the explosiveness of
2-(2-methylpropoxy)ethanol. As a result of the substance not containing
any structural features commonly associated with explosive behaviour, it
was concluded that the substance is not an explosive.
2-(2-methylpropoxy)ethanol subsequently does not require classification
(CLP Regulation (EC) No. 1272/2008).
The endpoint conclusion determined for
explosiveness is believed to be the key value and has been assigned a
Klimisch score of 2 (reliable with restrictions) given that it was
obtained from a weight of evidence approach.
