Description of key information
Biodegradability of Acetate C9 Nonylic has been investigated according to OECD guideline 301F. Under the test conditions, Acetate C9 Nonylic undergoes a biodegradation of 84% after 28 days. The 10-day window criterion is also fulfilled. Thus, Acetate C9 Nonylic is considered as readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The biodegradability of Acetate C9 Nonylic was studied according to OECD guideline 301F. The test system is closed and is therefore suitable for the examination of volatile materials. Inoculum was activated sludge originating from a wastewater treatment plant treating predominantly domestic sewage. Initial nominal concentration of the test substance was 30 mg/l as test material. Biodegradation of the test substance is recorded by the evolution of the O2 during the study. Acetate C9 Nonylic undergoes 84% biodegradation after 28 days. The 10-day window criterion is also fulfilled (22% on day 1, 70% on day 11). Therefore, and in accordance with the OECD Guidelines principles, Acetate C9 Nonylic is considered as readily biodegradable. Validity criteria are all met, the study is considered as acceptable for the endpoint.
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.
