Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The following text is copied from the EU Risk Assessment Report for hydrogen peroxide (European Commission 2003, page 35): "There are no experimental results on bioaccumulation available. Hydrogen peroxide is reactive and short-lived polar substance and no bioaccumulation is expected. Also the estimated log Kow of about -1.5 indicates negligible potential of bioconcentration in aquatic organisms. BCFs calculated according to the TGD for fish and earthworm are low, 1.4 and 3.3, respectively." In addition, the enzyme catalase is almost ubiquitously distributed in biotic systems enabling organisms to convert hydrogen peroxide into water and oxygen. In consideration of these points, a bioconcentration test in fish or other aquatic organisms is deemed not necessary.
