biodegradation in water: screening test, other
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
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:
other: calculated degradation
Remarks on result:
other: calculation result

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 %

Interpretation of results:
readily biodegradable
Executive summary:

The substance is readily biodegredable in aqueous solution

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) .
