Description of key information

The test substance e-caprolactone can be classified as readily biodegradable at a concentration of 10 mg/L. 

Key value for chemical safety assessment

Additional information

The biodegradability of e-Caprolactone was determined in a Modified Sturm test, using CO2evolution as the parameter for measurement. The test substance can be classified as readily biodegradable at a concentration of 10 mg/L. At a concentration of 20 mg/L the test substance cannot be classified as readily biodegradable as only 58% biodegradation occured after 28 days, however, the test substance can be considered as inherently biodegradable at the pass criteria were almost fulfilled.
