Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Calculated half life in air is 0.335 – 0.815 days (24 hr day; OH-concentration 0.5E+06 OH/cm³).

Key value for chemical safety assessment

Additional information

Based on an estimation using SRC AOP v1.92 with smiles notation, Fatty acids, C5-10, esters with pentaerythritol (CAS-No. 68424-31-7) is susceptible to indirect photodegradation in air. The estimated half time for the reaction with OH-radicals is 0.335 – 0.815 days (24 hr day; OH-concentration 0.5E+06 OH/cm³). However, indirect photodegradation in air is not a relevant rout since the substance is not likely to be present in the atmosphere due to the low vapor pressure (<0.001Pa).
