Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
According to Annex VII of the REACH Regulation (EC 1907/2006), the study on toxicity to aquatic plants does not need to be conducted if there are mitigating factors indicating that aquatic toxicity is unlikely to occur, for instance if the substance is highly insoluble in water.
Disperse Red 202 is found to be highly insoluble in water, with water solubility below LOD/LOQ of 1.08 mg/l.
Similarly, Similar Substance 01 has also a very low solubility in water, i.e. below the LOQ of 5 µg/l; moreover, in the validation of analytical method for Similar Substance 01, solubility in 20x AAP medium was found to be below LOQ.
Based on the structural similarity, the same behaviour in 20x AAP medium is expected for Disperse Red 202.
Overall, the significance of studies run at concentrations below LOQ was considered as low and the aquatic compartment was considered as not target of the substance toxicity.
Details on the read across are available in section 13.
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.
