Phototransformation in air
Administrative data
Link to relevant study record(s)
Description of key information
Phototransformation in air is not relevant due to low vapour pressure (< 0.001 Pa).
Key value for chemical safety assessment
- Half-life in air:
- 19.55 h
Additional information
Based on an estimation using AOPWIN v1.92, 2,2-bis[[(1-oxopentyl)oxy]methyl]propane-1,3-diyl divalerate (CAS-No. 15834-04-5) is susceptible to indirect photodegradation in air. The estimated half time for the reaction with OH-radicals is 19.55 h (24 h day; OH-concentration 0.5E+06 OH/cm³; Müller, 2013). However, indirect photodegradation in air is not a relevant route since the substance is not likely to be present in the atmosphere due to the low vapor pressure. As this study is not a standard information requirement in REACh and there is no indication from the Chemical Safety Assessment (CSA) on the need to investigate further the fate and behavior of the substance, no further testing is considered necessary for the substance.
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.
