Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation studies were performed with FAT 41'030/A, a structural analogue of FAT 41045. Both substances are very similar in their chemical structure and, as demonstrated, in a number of physicochemical properties. Therefore, the use of the studies with FAT 41030 for read-across is considered to be appropriate.
Two biodegradability tests are available. The results are summarized below:
The Ready Biodegradability of FAT 41030/A was performed under aerobic static exposure conditions using the Manometric Respirometry Test and used as the key study. The result showed the biodegradation of test item after 28 days was 0 % and the biodegradation of reference item after 14 days was 81 %. In the toxicity control no inhibitory effect was observed. Thus, the test item FAT 41030/A was not readily biodegradable after 28 days of incubation.
This finding was supported by a biodegradability test of the test material FAT 41'030/ A which was carried out under the conditions prescribed in Chemical Substances Control law. The attained percentage degradation values of the triplicate "test material degradation" systems based on biological oxygen demand were all 1 % (mean: 1 %). And the percentage degradation of test material FAT 41'030/ A was 0 % as mean of the triplicate system based on HPLC analysis.
The chemical oxygen demand (COD) was determined being 1675 mg O2/g
Simulation tests are not required at this tonnage band.
In conclusion, FAT 41'030/A and also its structural analogue, FAT 41045, are not 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.
