- Conclusions:
- According to OECD 301B test method, Everlan SL65 was not be considered readily biodegradable.
- Executive summary:
This test using the procedures outlined in the SuperLab Study Plan for M62-151100111001EN which is based on the SOP for the OECD 301B (SOPE-503) and OECD 301B (OECD, 1992). The results of this OECD 301B test for Everlan SL65 show that all validity criteria were met. Everlan SL65 was not be considered readily biodegradable under the test conditions and the percentage biodegradation of Everlan SL65 in sludge was less than 60 %.
Reference
At the end of the test, the CO2 production of blank control groups were 38.09 mg/L.

Description of key information
Not readily biodegradable (OECD TG 301B).
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, not fulfilling specific criteria
Additional information
The total amount of evolved CO2 in the blank control group was 38.09 mg/L. The difference between replicates of test group was less than 20%. At Day 14 during the study, the biodegradation of the reference control article was 69.55 % and the percent biodegradation in the toxicity control was 31.40 %. All test validity criteria were met. Everlan SL65 was not be considered readily biodegradable under the test conditions and the percentage biodegradation of Everlan SL65 in sludge was less than 60 %.
