- Details on results:
- After 28 days the sample attained oxygen depletion equivalent to 61 % biodegradation relative to theoretical oxygen demand. After nitrate and nitrite analysis this was adjusted to 67 % carbonaceous biodegradation. There was no evidence of inhibitory effects to sewage bacteria, under the conditions of the test.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable, but failing 10-day window
- Conclusions:
- The results of this test indicate that HEMA-PC is readily biodegradable, but fails the 10-day window.
- Executive summary:
This study was conducted to determine the ready biodegradability of HEMA-PC using EU Method C.4 -E (Closed Bottle Test). After 28 days the sample attained oxygen depletion equivalent to 61 % biodegradation relative to theoretical oxygen demand. After nitrate and nitrite analysis this was adjusted to 67 % carbonaceous biodegradation. There was no evidence of inhibitory effects to sewage bacteria, under the conditions of the test.
The results of this test indicate that HEMA-PC is readily biodegradable, but fails the 10-day window.
