Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 study of the "ready" aerobic biodegradability of DI-TERT-AMYL PEROXIDE using the OECD method 301 D shows that this item reached a maximum biodegradation level of 7 % in 28 days and 10 % in 56 days. These values were calculated on the measured initial concentration of the test item in the medium. As a consequence, DI-TERT-AMYL PEROXIDE is not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- not biodegradable
Additional information
- The oxygen uptake of the inoculum blank has been: 0.9 mg O2/L in 56 days, which is below 1.5 mg O2/L.
- The residual concentration of oxygen did not fall below 0.5 mg/L at any time.
- The difference of extremes of replicate values of the removal of test chemical at the plateau, at the end of the test, or at the end of the 10-d window, was less than 20%.
- The percentage degradation of the reference item reached a level of 89% by 14 days which is above the required level of 60%.
- In the toxicity control flasks, containing both the reference item and DI-TERT-AMYL PEROXIDE, the percentage of biodegradation reached 48% after 14 days. Since this value is higher than 25%, the test tem is not inhibitory for inoculum

These values were calculated on the measured initial concentration of the test item in the medium. As a consequence, DI-TERT-AMYL PEROXIDE is not readily biodegradable
The item did not demonstrate any inhibiting effect on the micro-organisms at the 2 mg/L nominal concentration (0.62 mg/L measured concentration)
