Potassium sorbate is the potassium salt of sorbic acid, chemical formula CH3CH=CH-CH=CH-CO2K. 
A white salt that is very soluble in water (58.2% at 20 °C). Used as a food preservative (E number 202). 

Potassium sorbate applications in food, wine, and personal care products. While sorbic acid is naturally occurring in some berries, virtually all of the world's production of sorbic acid, from which potassium sorbate is derived, is manufactured synthetically.
