- Study period:
- 07 January 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: An assessment was performed to establish the explosive behaviour of Reaction mass of 2-Propenoic acid, 2-methyl-, 2-dodecylhexadecyl ester and 2-Propenoic acid, 2-methyl-, 2-tetradecyloctadecyl ester through examination of its functionality.
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- An assessment was performed to establish the explosive behaviour of Reaction Mass of 2-Propenoic acid, 2-methyl-, 2-dodecylhexadecyl ester and 2-Propenoic acid, 2-methyl-, 2-tetradecyloctadecyl ester through examination of its molecular structure and functionality. A screening procedure was adopted in accordance with Annex VII of the REACH regulation ((EC) No 1907/2006), section 7.11 and Section 2.1.4.3 of the Classification, Labelling and Packaging (CLP) Regulation (EC) No.1272/2008. An evaluation of the functionality within the substance was performed to identify the presence of elements commonly associated with explosive properties as described in Table A6.1 in Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria. According to the CLP Regulation (EC) No 1272/2008, Section 2.1.4.3,Reaction Mass of 2-Propenoic acid, 2-methyl-, 2-dodecylhexadecyl ester and 2-Propenoic acid, 2-methyl-, 2-tetradecyloctadecyl shall not be classified as explosive where there are no chemical groups associated with explosive properties present in the substance.

- Reaction Mass of 2-Propenoic acid, 2-methyl-, 2-dodecylhexadecyl ester and 2-Propenoic acid, 2-methyl-, 2-tetradecyloctadecyl ester is not expected to possess explosive properties based on examination of its constituents
- Executive summary:
An assessment was performed to establish the explosive behaviour of Reaction Mass of 2-Propenoic acid, 2-methyl-, 2-dodecylhexadecyl ester and 2-Propenoic acid, 2-methyl-, 2-tetradecyloctadecyl ester through examination of its molecular structure and functionality. A screening procedure was adopted in accordance with Annex VII of the REACH regulation ((EC) No 1907/2006), section 7.11 and Section 2.1.4.3 of the Classification, Labelling and Packaging (CLP) Regulation (EC) No.1272/2008. An evaluation of the functionality within the substance was performed to identify the presence of elements commonly associated with explosive properties as described in Table A6.1 in Appendix 6 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria. The raw materials used to manufacture the substance do not contain any halogens, nitrogen, or metals, and these elements are not present in the final product. Oxygen is contained within Reaction Mass of 2-Propenoic acid, 2-methyl-, 2-dodecylhexadecyl ester and 2-Propenoic acid, 2-methyl-, 2-tetradecyloctadecyl ester and its substrates, however, it is not contained within chemical groups associated with explosive properties, as stated in section 2.1.4.3 of the CLP regulation. It should be noted that methacrylate ester homologues of the Reaction Mass of 2-Propenoic acid, 2-methyl-, 2-dodecylhexadecyl ester and 2-Propenoic acid, 2-methyl-, 2-tetradecyloctadecyl ester incorporate a C-C unsaturation, however, a single olefinic motif is unlikely to contribute to the explosive properties of the substance. The worst-case oxygen mass balance for the shorter-chain methacrylate homologue has been calculated as follows: Oxygen balance = -1600([2x+(y/2)-z]/Mwt) where CxHyOz = C32H62O2 Mwt = 478.8 = -1600(93/478.8) = -310.8 The calculated maximum oxygen balance for the substance is less than -200 indicating that the oxygen in the substance will not present an explosive hazard. It is concluded that Reaction Mass of 2-Propenoic acid, 2-methyl-, 2-dodecylhexadecyl ester and 2-Propenoic acid, 2-methyl-, 2-tetradecyloctadecyl ester does not have explosive properties and does not require classification for explosive properties.
