Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Flammability:
A test on the flammability according to the Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, 6th revised edition, Part III, Test N.1, Section 33.2.1.4 was negative for the structural analogue C20 Methacrytale. Therefore, Docosyl methacrylate (C22) is also not considered a flammable solid of division 4.1.
Pyrophoric properties:
In accordance with section 2.9.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.4.2 the classification procedure for pyrophoric liquids need not to be applied when experience in manufacturing or handling shows that the substance or mixture does not ignite spontaneously when coming into contact with air at normal temperatures. Based on the experience in handling and use the substance is not known to ignite spontaneously when coming into contact with air at normal temperatures. Thus, no study was conducted.
Substances which, in contact with water, emit flammable gases:
In accordance with column 2 of REACH Annex VI and with Regulation (EC) No 1272/2008 Annex I section 2.12.4.1 the classification procedure for this hazard class need not be applied if: a) The chemical structure of the substance or mixture does not contain metals or metalloids; or b) Experience in handling and use shows that the substance or mixture does not react with water, e.g. the substance is manufactured with water or washed with water; or c) The substance or mixture is known to be soluble in water to form a stable mixture. Based on the experience in handling and use the substance does not react with water and in addition the test substance is not pyrophoric. Thus, no study was conducted.
Justification for classification or non-classification
Based on the study results, the molecular structure and experience in handling and use, the substance was not classified and labelled as flammable, flammable in contact with water, pyrophoric, self-reactive substance, self-heating substance and organic peroxide according to Regulation (EC) No 1272/2008(CLP). In accordance with UN-Transport regulations the substance has not to be classified as readily combustible solid and self-reactive substance in Class 4 Division 4.1, as self-heating substance in Class 4 Division 4.2, as substances which in contact with water emit flammable gases in Class 4 Division 4.3 and as organic peroxide in Class 5 division 5.2.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
