Description of key information
DT50 (24h-day) = 51 hours (AOPWIN v1.92)
Key value for chemical safety assessment
Additional information
No experimental data evaluating the potential for photodegradation of methyl octanoate (CAS No.111-11-5) in air are available. Based on its vapour pressure value (71.9 Pa at 25 ºC), this substance can be expected to show potential for volatilization into air. Nevertheless, once present in the atmosphere, methyl octanoate is susceptible to undergo indirect photodegradation with an estimated half-life of 51 hours (QSAR calculation, AOPWIN v1.92, reaction with OH-radicals, 24h-day)(López Parrón, 2011). 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.
