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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
