Description of key information

Additional information

Potassic extracts is a multiconstituent substance with three simple organic salts as main constituents (i.e. potassium sulfate, sodium sulfate and calcium sulfate). The environmental fate and behaviour of potassic extracts is therefore assessed based on the properties of its three constituents.


The main constituents of potassic extracts completely dissociate into ions in water and are not susceptible to photodegradation in air , water and soil. Due to their inorganic nature, standard biodegradation testing systems are not applicable.


Based on their high water solubility and their ionic nature, they are not expected to adsorb onto soil and sediment or bioaccumulate in aquatic organisms.
