Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No data is available on the substance.
However, information of Similar Substance is reported. Similar Substance, historically named as Acid Yellow 099 (EC 233-748-3), was tested in two FAT. No determination of components of these FAT was carried out, thus no conclusion could be drawn whether Similar Substance is a multi-constituent or an UVCB. Accordingly, it was not possible to decide whether test substance and Similar Substance may be considered as the same.
In particular,
- FAT 20'040/A, no certificate of analysis available. In one study, purity of 82 % was given.
- FAT 20'040/B, certificate of analysis reported: 39.7 % main product and 41 % unknown coloured by-products giving a total of 77.7 %, reported as purity in studies.
Based on available studies on FAT 20'040/B, it is considered as not rapidly degradable. Indeed, the ratio BOD5/COD resulted close to 0, namely far below the threshold of 0.5, in two studies. However, in another test on FAT 20'040/A, it resulted as inherently biodegradable with ca. 45 % of degradation after 28 days and upon correction for adsorption.
Basede
on this information the substance is considered to be not readily 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.
