Potassium sorbate

Other Name(s):

E 202; CAS# 24634-61-5; Sorbic Acid Potassium Salt

Potassium sorbate is a naturally occurring compound found in some berries like those of the Mountain Ash (Sorbus aucuparia). But commercially available sources of potassium sorbate are made under strictly regulated laboratory conditions.

Is Potassium sorbate Faithful to Nature?

Depends.

Potassium sorbate is a nature-identical preservative that helps to prevent waste by spoilage.

Benefits: Why is Potassium sorbate used?

Mild Preservative

Potassium sorbate is a mild preservative, much gentler than formaldehyde releasing agents. Its is widely used in foods, drinks, and personal care products.

Gentle on Humans

Potassium sorbate doesn’t kill beneficial bacteria in the gut or on the skin.

Extends Shelf Life

Potassium sorbate stops the growth of mold, yeast, and fungi and can therefore prolong the shelf life of foods.

Subject to Strict Controls

Potassium sorbate use is strictly controlled by governing bodies.

On the Shelf: Which Products Use Potassium sorbate?

Potassium sorbate is used widely in cosmetic and food products to extend their shelf life. It inhibits the growth of yeast and mould. It’s most commonly found in foundations, moisturisers, shampoos, wines, ciders, cheeses, pickles, and fruit juices.

Production: How is Potassium sorbate Made?

Potassium sorbate is made by reacting sorbic acid with potassium hydroxide at room temperature in the presence of distilled water. The resulting potassium sorbate is then formed into crystals by dehydration. Reputable laboratories will subject the crystals to quality testing, ensuring no contaminants are present.

Interesting Fact: Potassium sorbate

ECOCERT, Soil Association and COSMOS (some of the most widely recognised organic cosmetic certifiers) both approve of potassium sorbate as a preservative.

The European Food Safety Authority has indicated that potassium sorbate is safe up to a daily intake limit of 25 mg per kg of bodyweight. For the average adult weighing 62 kg, that’s a daily intake limit of 1550 mg.
