Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The chemical safety assessment revealed that direct and indirect exposure of soil and terrestrial enviroment is practically negligible, as:

1) Methyl-ethylketone peroxide is manufactured and formulated in completely closed systems. Thus, direct and indirect exposure of soil and the terrestrial environment during manufacturing and formulation is practically negligible.

2) Methyl-ethylketone is not coming in contact with final consumers, because substance is chemical bounding completely during industrial polymerisation process. Therefore, the direct and indirect release of methyl-ethylketone peroxide to soil and terrestrial environment is practically negligible.

Therefore, direct and indirect exposure of methyl-ethylketone peroxide to soil and the terrestrial environment is unlikely and performance of tests for toxicity to soil micro- and macroorganisms, arthropods, terrestrial plants and birds are scientifically not justified.

For more details on exposure assessment see risk assessment report in section 13.
