Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A fugacity level III calculation, using a four compartment (air, water, soil and sediment) model has been conducted using the Mackay model (DeGroot, 2005). A 100 % release to the water compartment was assumed. Based on the results of the calculation, peracetic acid is expected to partition almost exclusively to the aquatic compartment (99.95 %) with the remainder to sediment (0.040 %), soil (0.002) and air (0.009 %). The measured Henry’s Law constant of 0.217 Pa m³ mol-1 indicates that volatilisation from surface water is not expected. Thus, high water solubility, low vapour pressure and low octanol-water partition coefficient lead to the conclusion, that peracetic acid is mainly found in the water compartment without removal via volatilisation.
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.
