Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One ready biodegradation study is available for Sorbitan, octanoate (2:3) (CAS No. 91844-53-0).
This key study was carried out with Sorbitan, octanoate (2:3) (CAS No. 91844-53-0), following the OECD Guideline 301 F and according to GLP (Ley, 2005). A mixed inoculum containing microorganisms from sewage plants, from natural waters and from air was used. During the 28-day test period, biodegradation reached 89%, based on O2 consumption, and the 10-day window criterion was fulfilled.
The supporting anaerobic degradation study was performed according to OECD Guideline 311 and GLP (Flach, 2009). Digested sludge from a municipal wastewater treatment plant was used as inoculum. After the 61 days test period 83% biodegradation was observed.
In conclusion, Sorbitan, octanoate (2:3) (CAS No. 91844-53-0) can be considered 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.
