Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
FAT 40543/A was tested for ready and inherent biodegradability as follows:
The ready biodegradability of FAT 40543/A was determined in a 28 days "Manometric Respirometry Test" according to the OECD Guideline for Testing of Chemicals, No. 301F.
The test substance was tested in a concentration of 100 mg/l. The reference substance (sodium benzoate) was also tested in a concentration of 100 mg/l. Whereas the reference substance reached a biodegradation rate of 90% showing the test system to be efficient, the test substance FAT 40543/A only achieved 2% biodegradation after 28 days.
The inherent biodegradability of FAT 40543/A was determined in a 28 days MITI (II) - Test according to the OECD Guideline for Testing of Chemicals, No. 302C. The test substance was tested in a concentration of 30 mg/l and showed no biodegradation (0%) within 28 days. The reference substance (sodium benzoate) was tested in a concentration of 100 mg/l and achieved 89% biodegradation within 28 days.
In a separate experiment the COD (Chemical Oxygen Demand) of FAT 40543/A was determined being 1.25 g O2/g and is thus in good agreement with the ThOD (Theoretical Oxygen Demand) of 1.33 g O2/g. Considering the BOD5 of 5 mg O2/g found in the ready biodegradability test (Manometric respirometry test) the BOD5/COD ratio is 0.4% and thus the substance is considered non-biodegradable
In conclusion it can be stated that FAT 40543/A is non-biodegradable under aerobic conditions.
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).
