Potassium Sorbate is the INCI (International Nomenclature of Cosmetic Ingredients) name for potassium sorbate, a preservative agent. Potassium sorbate is a potassium salt of sorbic acid. It is notably used as a food additive, found in yogurts, beverages, and sauces. In its natural state, potassium sorbate is present in the Rowan tree.

Potassium Sorbate, what is its use?

Potassium sorbate is also used in the field of cosmetology as a preservative agent. It inhibits the growth of microorganisms in preparations. It helps to combat the formation of yeasts and molds in water-based preparations. Its role is thus to extend the shelf life of skincare products. It is also used for its ability to reduce or inhibit the odor or even the taste of the base of the preparations. It is particularly used to preserve formulas that include a base. The maximum concentration allowed according to European regulations is 0.6%. Its concentration should be 0.1% to 0.2% if it is combined with other preservatives.

Potassium Sorbate is found in intimate wipes, makeup removal gels, and body creams.
