EC number: 221-111-2 | CAS number: 3006-86-8
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.
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.
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.
