Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Phototransformation in air

Description of key information
Phototransformation in air is not relevant due to the low vapour pressure.
Key value for chemical safety assessment
Additional information
Based on QSAR calculations for the main components of 2-Butenedioic acid (E)-, di-C14-16-alkyl esters (List No 695-949-6) using AOPWIN v1.92, the substance is susceptible to indirect photodegradation in air. The estimated half time for the reaction with OH-radicals is in the range of 7.56 to 8.69 hours (24 h day; OH-concentration: 0.5E+06 OH/cm3). However, photodegradation is not an important environmental fate process since the substance is not expected to evaporate into the atmosphere due to its low vapour pressure of < 0.001 Pa at 20
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.
