Potassium sorbate, also known as 2,4-hexadienoate, is a potassium salt of Sorbic acid. Its Molecular formula is C6H7O2K. It is white to light yellow scaly crystals, crystal particles or crystal powder, odorless or slightly smelly, and it is easy to absorb moisture, be oxidized and decomposed to change color after long-term exposure to the air. Easily soluble in water, soluble in propylene glycol and ethanol. It is often used as a preservative and damages many enzyme systems by binding with thiol groups in microbial enzyme systems. Its toxicity is much lower than other preservatives and is widely used. Potassium sorbate can fully play the role of anti-corrosion in acid medium, and has little anti-corrosion effect in neutral conditions.
