Description of key information

Readily biodegradable: 76.0% (CO2 evolution) after 28 d (OECD 301B)

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

One study investigating the ready biodegradability offatty acids, C16-18 and C18-unsaturated, tetraesters with pentaerythritol (CAS 68604-44-4)is available (Häner, 2007). This study was conducted according to OECD 301B using non-adapted activated sludge as inoculum. A test concentration of 22.8 mg/L (TOC) was applied. Based on CO2 evolution a mean biodegradation of 76% was observed after 28 days. Hence, the substance is determined to be readily biodegradable according to OECD criteria.
