Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Short-term toxicity to fish
The 96 h-LC50 and 96 h-LL50 values were determined to be > 0.64 mg/L and > 100 mg/L.
Long-term toxicity to fish
A fish early life toxicity study with Danio rerio was performed. The most sensitive endpoint was the fish survival at test end, thus the NOEC / LOEC were determined to be 64.5 / 153 µg/L (mean measured).
Short-term toxicity to aquatic invertebrates
The 48-hour EC50 of cyclohexylidenebis[tert-butyl] peroxide in a static test system is > 1000 mg/L expressed as initial loading rate (EL50), corresponding to 0.598 mg/L expressed as actual concentration (measured concentration at the beginning of the test in the saturated solution obtained from the loading rate 1000 mg/L) for Daphnia magna.
Long-term toxicity to aquatic invertebrates
No effects on daphnids were observed in the long-term toxicity test. Thus, the NOEC was determined to be >= 0.112 mg/L (time-weighted mean measured concentration).
Toxicity to aquatic algae and cyanobacteria
The 72 hour ErC50 and the EbC50 of cyclohexylidenebis[tert-butyl] peroxide in a static test system are > 10.0 mg/L expressed as initial loading rate (EL50), corresponding to approximately 0.5 mg/L expressed as acutual concentration (the assumed limit of solubility), for Pseudokirchneriella subcapitata.
Toxicity to microorganisms
The 3-hour EC50 of cyclohexylidenebis[tert-butyl]peroxide was determined to be > 20 mg/L for activated sludge. The 3-hour EC10 of the test substance was > 20 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
