Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The toxic effects to microorganisms of this substance are read-across from data obtained with dilauroyl peroxide: EC50 was determined to be > 1000 mg/L based on nominal concentration, when absorbed onto silica gel. No NOEC was obtained.
Key value for chemical safety assessment
Additional information
There is no test performed with didecanoyl peroxide. The toxic effects to microorganisms of this substance are read-across from data obtained with dilauroyl peroxide. An activated sludge respiration inhibition test was performed with dilauroyl peroxide, according to the OECD 209 guideline. The test substance was not soluble in water and therefore the activated sludge was exposed to dilauroyl peroxide adsorbed onto silica gel at a concentration of 1 g/litre. By this exposure an effect was recorded indicating that the obtained distribution of the test substance in the water system did inhibit the activated sludge slightly (24%). The EC50 was determined to be > 1000 mg/L based on nominal concentration, when absorbed onto silica gel. No NOEC was obtained.
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.
