Any other information on results incl. tables
The biodegradation within the 10-day-window was 82.5 %. The 10-day-window starts at day 1.
No significant abiotic degradation of Acylglycinate GCK-11-T was noticeable after 28 days of incubation.
The biodegradation of the item mixture in the toxicity control was found to be 87.9 % after 14 days of incubation. Thus, the demanded threshold value of 25 % is exceeded and the test item can be identified as non-toxic in a ready biodegradability test.
The reference item sodium benzoate was degraded to 88.6 % within the first 14 days.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
