Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In general, textile chemicals especially textile dyes are designed to be no organic substrates for microorganisms, fungi and higher organisms. Therefore, these substances are considered to be not biodegradable at all. Nevertheless, basic studies to assess biodegradability of the test item have been performed. A study reported biological elimination of FAT 40032 as 8 %. BOD5 and COD values of 13 and 935 mg O2/g were reported in two other key studies respectively. Based on the BOD5/COD quotient which is not >0.5, the substance is not indicative of rapid degradation. Taking data from % degradation test and BOD5/COD quotient into account, the test substance FAT 40032 is not biodegradable.
Additional information
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.
