Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One ready biodegradation study is available for Amides, C8-10, N-(hydroxyethyl) (CAS 1443751-77-6).
The key study carried out with Amides, C8-10, N-(hydroxyethyl) (CAS 1443751-77-6), was conducted following the OECD Guideline 301 F and according to GLP (Evonik Industries, 2013). Activated sludge from a municipal sewage treatment plant was used as inoculum. The biodegradation of Amides, C8-10 (even-numbered), N-hydroxyethyl in the static test was found to be 95 % with a standard deviation of 3.4 % for a concentration of 100 mg test item per liter and 92 % with a standard deviation of 8.4 % for a concentration of 20 mg test item per liter after 28 days. For a concentration of 100 mg test item per liter biodegradation within the 10-day-window – which started at day 2 – was found to be 79 %. For a concentration of 20 mg test item per liter biodegradation within the 10-day-window – which started at day 1 – was found to be 77 %.
Therefore, Amides, C8-10 (even-numbered), N-hydroxyethyl can be considered as readily biodegradable.
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.
