Potassium Sorbate Food Grade

Potassium Sorbate is the potassium salt of sorbic acid and is widely used as an effective preservative in food, cosmetic, and personal care formulations. It is a white, odorless, crystalline powder that helps inhibit the growth of yeasts, molds, and certain microorganisms.

Due to its effectiveness and good solubility, Potassium Sorbate is commonly used in water-based products to help maintain product quality and extend shelf life.

INCI Name

Potassium Sorbate

Recommended Use Level

Typically 0.1–0.3%, depending on the formulation, pH, and applicable regulatory requirements.

Potassium Sorbate performs best in acidic formulations, so the final product pH should be considered for optimal preservative performance.

Solubility & Phase

Water-soluble. Dissolve in the water phase with adequate mixing. Preservative effectiveness is generally enhanced at lower pH levels.
