Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Peracetic acid can be regarded as readily biodegradable. It will be degraded in sewage treatment plants if the influent concentration is not extremely high (e. g. > 100 ppm). If effluents generated during the production or use of peracetic acid are treated by a waste water treatment plant, no emission of peracetic acid to the aquatic environment is expected.
If peracetic acid reaches surface water, it can be expected to be degraded rapidly, mainly by abiotic rather than biotic decomposition / degradation processes. The same holds true for peracetic acid in contact with sediment and soil, although adsorption to sediment or soil is not likely to occur due to the physicochemical properties of peracetic acid.
Because of the dominance of abiotic decomposition / degradation processes no specific half-lives for biotic degradation can be derived. Instead, the half-lives listed under "Abiotic degradation" are used as input parameter for the environmental exposure assessment.
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.
