Description of key information
Based on a weight of evidence approach with data on constituents, the registered substance is regarded as not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The registered is a Natural Complex Substance (NCS) with a well-defined composition. Typical % of constituents as well as their ranges within the substance are known. Therefore, it has been decided to assess the ready biodegradability of the substance with a constituents approach.
The major constituents of the registered substance represent 94.5% of the NCS based on a typical composition.
All these constituents were found to be not readily biodegradable (see table below):
