Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
Acute classification
The existing acute data for fish, algae and Daphnia show a NOEC value > 100 mg/L (loading). As all effect values are above 1 mg/L, there is no acute classification for this substance.
Chronic classification
Bis(2,4-dichlorobenzoyl) peroxide is not readily biodegradable, and the measured log Kow is 6. The chronic data available are 72 h-ErC10, > 100 mg/L (loading) for algae, 21d-EC10 >10 mg/L (loading) for Daphnia and 33d-NOEC ≥ 10 mg/L (loading) for fish.
Based on chronic data: No classification
Category chronic 4 evaluation - Substance is poorly water soluble, with no acute or chronic toxicity recorded up to the water solubility, is not rapidly degradable and the log Kow > 4. However the available chronic toxicity endpoints are all > water solubility, thus it does not fit into this category.
Most stringent outcome: No classification
Overall classification: None
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
