Description of key information
Readily biodegradable: 88% (O2 consumption) in 28 days
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One valid ready biodegradation study is available for Sorbitan stearate (CAS No. 1338-41-6).
This key study was carried out with Sorbitan stearate (CAS No. 1338-41-6), following the OECD Guideline 301 C and according to GLP (MoE, 1996). A mixed inoculum containing microorganisms from sewage plants and from natural waters was used. During the 28-day test period, biodegradation reached 88%, based on O2 consumption.
A second study conducted with Sorbitan stearate (CAS 1338-41-6) was disregarded, due to lack of detailed information. No full report is available, and no results were given.
In conclusion, Sorbitan stearate (CAS No. 1338-41-6) can be considered readily biodegradable according to OECD criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
