Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hydrolysis of dicumyl peroxide was tested in a study according to OECD test guideline 111. The shortest half-life at environmentally relevant temperatures was found to be 77 days at pH 7 and 10 °C. Degradation products could not be detected.

Key value for chemical safety assessment

Half-life for hydrolysis:
77 d
at the temperature of:
10 °C

Additional information

The reaction rate constants calculated within the hydrolysis study show dependency from the temperature, as expected, but no significant influence of the different pH values could be observed. At an environmentally relevant temperature of 10 °C, only moderate degradation could be observed at the different pH values (81.8–91.3 % of the initial concentration after 14 days). Besides the test item no degradation products could be found and analytically identified throughout the study.
