- key study
- Study period:
- 60 days
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Guideline study. Extended OECD 301D study with substance specific analysis, performed 2020, GLP
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 301 D (Ready Biodegradability: Closed Bottle Test)
- Version / remarks:
- Extended to 60 days to investigate inherent biodegradation
Test material analysis performed to investigate possible transformation products - GLP compliance:
- yes (incl. QA statement)
- Specific details on test material used for the study:
- Commercial grade material
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, non-adapted
- Duration of test (contact time):
- 60 d
- Initial conc.:
- > 2 - < 5 mg/L
- Based on:
- act. ingr.
- Parameter followed for biodegradation estimation:
- DOC removal
- Reference substance:
- benzoic acid, sodium salt
- Parameter:
- % degradation (DOC removal)
- Value:
- ca. 8
- Sampling time:
- 14 d
- Parameter:
- % degradation (DOC removal)
- Value:
- ca. 0
- Sampling time:
- 35 d
- Parameter:
- % degradation (DOC removal)
- Value:
- ca. 0
- Sampling time:
- 60 d
- Details on results:
- The toxicity control indicated no inhibition of the control substance.
The reference substance acheived minimum requirements for validiation, with 62% after 14 days - Validity criteria fulfilled:
- yes
- Interpretation of results:
- under test conditions no biodegradation observed
- Conclusions:
- Although some of the test bottles demonstrated some biodegradation, this was not considered significant.
There appears to be no transformation of the product by abiotic processes within thhis test system.
Reference
Analysis for the test substance demonstrated no transformation with a high level recovery of the substance at the end of the 60 day exposure period.
Description of key information
An extended Closed Bottle test has been performed for 60 days and analysis performed to determine formation of tranformation products through biological or abbiotic processes.
There was no significant biodegradation and no detection of transformation products.
Key value for chemical safety assessment
- Biodegradation in water:
- not biodegradable
- Type of water:
- freshwater
