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.
