Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 due to low vapour pressure (< 0.0001 Pa).
Key value for chemical safety assessment
Additional information
Based on an estimation AOPWIN v1.92 for the main components, fatty acids, C8, C10, C12, C14, C16 esters with pentaerythritol, reaction product of coconut oil fatty acids, C8-10 fatty acid mix and pentaerythritol (CAS-No. 85049-33-8) is susceptible to indirect photodegradation in air. The estimated half time for the reaction with OH-radicals is 0.196 – 0.438 days (24 hr 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 very low vapor pressure of < 0.0001 Pa at 20 °C. As this study is not a standard information requirement in REACH and there is no indication from the CSA on the need to investigate further the fate and behaviour of the substance, no further 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.
