Description of key information
Ignition was observed but the flame died after five seconds after two minutes of heating time and no propagation of the flame was observed.
Therefore, the test item hydroxy(2-methylprop-2-enoato-O)zinc should be considered as not highly flammable.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
Key study was performed in order to determine the flammability of the test item Hydroxy(2-methylprop-2-enoato-O)zinc according to theEU-Method A.10 and UN N.1 under GLP.
Ignition was observed but the flame died after five seconds after two minutes of heating time and no propagation of the flame was observed.
Therefore, the test item hydroxy(2-methylprop-2-enoato-O)zinc should be considered as not highly flammable.
The result has been considered as reliable without restriction because the test was performed in compliance with OECD and EU guidelines giving scientifically valid results.
Justification for classification or non-classification
As the substance failed to ignite in the burning rate test (EC A10 method), it is classified as not highly flammable according to Directive 67/548/EEC Annex VI criteria.
The preliminary test in EC A10 method is identical to the one of test N1 of UN manual of tests and criteria (Recommendations on the transport of dangerous goods,4th revised edition, 2008), therefore the result also fulfills criteria for non-classification according to Regulation (EC) No.1272/2008 (CLP)."
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.
