Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The effective concentration (EC50) value based on QSAR prediction of D&C Yellow No. 11 (CAS No 8003-22-3) in aquatic algae (Scenedesmus subspicatus (new name: Desmodesmus subspicatus)) in 72 hrs was estimate to be 0.47465 mg/l.

Key value for chemical safety assessment

EC50 for freshwater algae:
0.475 mg/L

Additional information

The effective concentration (EC50) value based on QSAR prediction of D&C Yellow No. 11 (CAS No 8003-22-3) in aquatic algae(Scenedesmus subspicatus (new name: Desmodesmus subspicatus)) in 72 hrs was estimate to be 0.47465 mg/l. Also in aquatic algae(Pseudokirchnerella subcapitata) in 72 hrs was estimate to be4.8425 mg/l

Therefore the EC50 was considered to be0.47465mg/L for D&C Yellow No. 11 and it is not readily biodegradable in nature indicating that test substance likely to exhibit toxicity to aquatic algae in aquatic chronic 1 category as per the CLP criteria.
