Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: screening test, other
- Remarks:
- calculation
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Principles of method if other than guideline:
- calculation based on test results of epsilon-Caprolactam
- GLP compliance:
- no
- Parameter:
- other: calculated degradation
- Value:
- 80
- Remarks on result:
- other: calculation result
- Interpretation of results:
- readily biodegradable
- Executive summary:
The substance is readily biodegredable in aqueous solution
Reference
Biodegradability of epsilon-Caprolactam: 82 %
Biodegradability of sodium caprolactamate: 113/135*82 % = 69 %
Biodegradability of BRUGGOLEN C 10: (0.83*82%+0.17*69%)/100 = 80 %
Description of key information
Readily biodegradable according to OECD criteria (based on calculation).
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Readily biodegradable: 80 % (14 d) .
