Description of key information
Not relevant due to low vapour pressure
Key value for chemical safety assessment
Additional information
No experimental data evaluating the potential for photodegradation of methyl laurate (CAS No. 111-82-0) in air are available. Therefore, a QSAR calculation using the AOPWIN v1.92 program has been performed, resulting in an estimated half-life of 29.2 hours (reaction with OH-radicals, 24h-day)(López Parrón, 2011). Nevertheless, this is not expected to be a relevant environmental fate process, since methyl laurate is not likely to be present in the atmosphere in relevant amounts based on its vapour pressure value (0.55 Pa at 25 °C). As this study is not a standard information requirement according to Regulation (EC) No. 1907/2006 and there is no indication from the CSA according to Annex I on the need to investigate further the fate and behavior of the substance (Annex X requirement), no testing is considered necessary.
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.
