Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.
FAT 20'040/B was tested on three trophic levels and on microorganisms.
Short-term toxicity to fish:
- LC50 (96 h) = 445 mg/l
Short-term toxicity to aquatic invertebrates:
- EC50 (48 h) > 0.2 mg/l, i.e. highest attainable concentration
Toxicity to algae and cyanobacteria:
- EC50 (96 h)> 0.22 mg/l, i.e. highest attainable concentration
Toxicity to microorganisms:
-EC50 (3 h) > 100 mg/l
Moreover, FAT 20'040/A was tested for toxicity on fish.
Short-term toxicity to fish:
- LC50 (96 h) = 1000 mg/l
Based on available information from read across data, no concern was raised. In particular:
- fish data is above the threshold for classification in the CLP Regulation (EC 1272/2008);
- ca. 5 % effect is seen at the highest attainable concentration in tests on daphnia and algae and EC50 is considered far above the solubility limit.
Therefore, aquatic toxicity was not further investigated and endpoints were not filled in, according to Article 12 of the REACH Regulation (EC 1907/2006).
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.
