Description of key information
Key value for chemical safety assessment
Additional information
Purpose: The purpose of this expert statement was to evaluate the oxidizing properties of the test substance.
Guidelines: The study procedures described in this statement are based on the following internationally accepted guidelines and recommendations:
- Commission Regulation (EC) No 440/2008 of 30 May 2008, Annex Part A, Methods for the determination of physico-chemical properties, A.21 Explosive properties (liquids), (published in the Official Journal of the European Union L 142 of 31 May 2008)
- Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria, Fifth revised edition, United Nations, New York and Geneva, 2009 (ST/SG/AC.10/11/Rev.5)
Statement: The test method for the determination of oxidising properties of a substance as described in Test Guideline A.21, Annex Part A of Commission Regulation (EC) No 440/2008 of 30 May 2008, was replaced by an evaluation on a theoretical basis via chemical structure considerations. Compounds which comprise highly electronegative atoms, i.e. oxygen, fluorine or chlorine, are likely to possess oxidizing properties. Similarly, compounds where those elements are present not only bonded to carbon and/or hydrogen, oxidizing properties have to be expected. The chemical structure of “Dibutylmagensium ca. 15 % in Hexane” does not comprises structural features, which lead to the conclusion that oxidizing properties have to be expected. The chemical structure of the solvent Hexane does not comprise chemical groups, which indicate oxidizing properties.
Conclusion: In conclusion, considering the chemical structure of “Dibutylmagensium ca. 15 % in Hexane” oxidizing properties have not to be expected. The substance is thus not classified for oxidizing properties according to Directive 67/548/EEC (DSD) and according to Regulation (EC) No 1272/2008 (CLP). This is in line with other official classifications of chemically similar substances in the EU.
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
