Description of key information
Key study:- Givaudan (1995), Ready biodegradability (OECD 301F): Readily biodegradable (89% biodegradation within the 10 day window and 96% biodegradation within 28 days).
Supporting study:- Givaudan (1997), Ready biodegradability (OECD 301B): Readily biodegradable (Attaining the 60% biodegradation pass level within the 10 day window and 84.6% biodegradation by 28 days).
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The key study for ready biodegradability (Givaudan, 1995) was determined in a GLP compliant study performed in accordance with the standardised guideline OECD 301F (Manometric Respirometry Test) with a sufficient level of detail to assess the quality of the presented data. The study was performed to a good standard and was assigned a reliability score of 1 in accordance with Klimisch (1997).
The supporting study for ready biodegradability (Givaudan, 1997) was determined in a GLP compliant study performed in accordance with the standardised guideline OECD 301B (CO2 Evolution Test) with a sufficient level of detail to assess the quality of the presented data. The study was performed to a good standard and was assigned a reliability score of 1 in accordance with Klimisch (1997).
The ready biodegradability of the test substance was demonstrated with two different methods; the biodegradation was determined to be 84.6 and 96% after 28 days, both tests also passed the 10 day window criterion. The test substance was therefore considered to be readily biodegradable under the conditions of the two tests.
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).
