Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Due to the salt-character of the substance the calculation of a fugacity model is not appropriate. Based on the physico-chemical properties ofammonium sulfate, water is expected to be the main target compartment. Based on the high water solubility a low geo-accumulation potential and high mobility in soil is to be expected. However, due to ion-ioninteractions it is to be expected that mobility in soil is significantlyreduced. Ammonium sulfate will not volatilise from soil.

Because of the chemical structure of ammonium sulfate, the Henrys Law Constant is not assignable.
