Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Readily biodegradable:  76 -96 % (CO2 evolution) after 28 d (OECD 301B)

Key value for chemical safety assessment

Additional information

Two studies, investigating the ready biodegradability of Fatty acids, C5-10, esters with pentaerythritol (CAS-No. 68424-31-7) according to OECD 301B (CO2 Evolution Test), are available. In both studies domestic activated sludge (non adapted) was used as inoculum. In the key study (Häner, 2006) a mean degradation of 96% and in the supporting study (Muckle, 2009) of 78% could be observed at test termination after 28 days. In both studies the 10-day-window was reached. Therewith the test substance can be classified as readily biodegradable according to OECD criteria.
