Potassium sorbate is the potassium salt of sorbic acid , chemical formula CH3CH=CH−CH=CH−CO2K . It is a white salt that is very soluble in water ( 58.2% at 20 °C ) . It is primarily used as a food preservative ( E number 202 ) . Potassium sorbate is effective in a variety of applications including food , wine , and personal-care products . While sorbic acid occurs naturally in some berries , virtually all of the world 's production of sorbic acid , from which potassium sorbate is derived , is manufactured synthetically .
