Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The acute and chronic toxicity to the aquatic compartment is considered to be no effects at the water solubility limit (saturation).
Conclusion on classification
Based on available freshwater toxicity data of the closely related read-across substance 2-Isopropylthioxanthone ("ITX", CAS 5495-84-1, EC 226-827-9), toxicity to the aquatic compartment is considered to be no effects at the water solubility limit (saturation)
The less water soluble registration substance 2,4-diethyl-9H-thioxanthen-9-one ("DETX", CAS 82799-44-8, EC 280-041-0) is therefore not classified in the EU for acute or chronic toxicity according to Regulation (EC) No. 1272/2008 (as amended).
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.
