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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Short-term toxicity to aquatic invertebrates

Description of key information
EC50 (48 h, Daphnia magna) > 100 mg/l (nominal)
Key value for chemical safety assessment
Additional information
No data on Disperse Yellow 231 was available, thus 2 experimental studies on the short-term toxicity to aquatic invertebrates on a structural analogue, i.e. Similar Substance 01, were used for the assessment. Details on the read-across are available in section 13.
Both studies were 48 hours of exposure of Daphnia magna to the test item in a static, freshwater test, performed according to the OECD guideline 202 (1984) and the EU method C.2 (1992). Both studies demonstrated that the concentration which leads to 50 % immobilisation of D. magna (EC50) after 48 hours of exposure is greater than 100 mg/l, reported as nominal concentration due to poor water solubility.
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.
