Applicant's summary and conclusion

Conclusions:
Bioelimination (14h): 17 - 37 %, with sudge
Bioelimination (14h): 76 % with adapted sludge
Executive summary:

The bioelimination potential fo the test item was assessed by stability test according to the Hoechst Nr.4, November 1973. The evaluation was performed with sludge and with adapted sludge, over a period of 14 days.

Bioelimination (14h): 17 - 37 %, with sludge

Bioelimination (14h): 76 % with adapted sludge.
