Results and discussion
Applicant's summary and conclusion
- Conclusions:
- The bioelimination based on TOC was found to be 33 % in 3 hours and 46 % in 14 days.
- Executive summary:
The bioelimination of the test item was evaluated in a test based on the determination of total organic carbon (TOC), according to an internal method. Two test item concentrations were tested and the percentage elimination was evaluated over a 14-day study period.
At a concentration of 800 mg test item/l (120 mg TOC/l), the test item was degraded by 26 to 37 %. At a concentration of 2700 mg test item/l (400 mg TOC/l), the test item was degraded by 31 to 39 %. The bioelimination based on TOC was found to be 33 % in 3 hours and 46 % in 14 days.
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.
