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.
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.
