Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Phototransformation in air is not relevant.
Key value for chemical safety assessment
Additional information
No experimental studies investigating the phototransformation in air of any member of the PFAE linear is available. Based on QSAR calculations using AOPWIN v1.92, all substances are susceptile to indirect photodegradation in air. The estimated half times for the reaction with OH-radicals are in the range of 6 - 37 hours (24h day; OH-concentration: 0.5E+06 OH/cm3). However, photodegradation is not an important environmental fate process since all substances are not expected to evaporate into the atmosphere due to the low vapor pressure of < 1 Pa at 20 °C.
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.
